During her travels as a mercenary, Kassandra came into conflict with the secretive Cult of Kosmos, an organization intent on controlling the entire Greek world. She later opposed the Order of the Ancients, who sought to hunt her down, due in part to her nature as a "Tainted One", and also for her allying herself with Darius. For her opposition against the Cult and the Order, Kassandra is considered one of the early precursors to the Assassin Brotherhood.
She was the older half-sister of Alexios and, through her mother, Myrrine, the granddaughter of King Leonidas I of Sparta. Although raised by her step-father, Nikolaos, Kassandra was the biological daughter of Pythagoras. She was also the mother of Elpidios, an ancestor of Aya, one of the co-founders of the Hidden Ones.
- Kassandra: "Sparta. All I remember is the bottom of Mount Taygetos."
- Myrrine: "When I brought you to the Pythia as a baby, she never said we would live a nightmare. She said you had such promise."
- Kassandra: "The Pythia can't predict everything."
- —Kassandra discussing her childhood with Myrrine, 429 BCE.[src]-[m]
Kassandra was born in Sparta, in 458 BCE, to Myrrine, the daughter of the late King Leonidas I, and the philosopher Pythagoras, whose lifespan was extended due to the Staff of Hermes Trismegistus he possessed. Shortly after her birth, her father departed from Sparta on a quest to learn more about the Isu and the staff he possessed. As such, Myrrine was left to raise Kassandra alone. As a baby, Myrrine brought Kassandra to the acting Pythia, who proclaimed that the child showed a lot of promise. At one point, Myrrine later met and married the Spartan general Nikolaos who, despite Kassandra not being his own flesh and blood, raised her as one of his own. Kassandra would later gain a younger brother, Alexios.
Owing to her lineage as being a granddaughter of Leonidas, great hopes were placed upon her to live up to the strength and valor of Leonidas. As such, Kassandra was trained to fight at a young age by Nikolaos. While training in the woods near Sparta, Myrrine presented Kassandra with Leonidas' broken spear that she inherited as a heirloom. Since then, the spear never left Kassandra's side even in her sleep, with her telling her parents that she needed it "to fight the monsters in [her] dreams." Like other Spartan children, Kassandra also participated in the agoge, learning there about various things, including the Gortyn Code.
Exile From Sparta
When Kassandra was seven, the Pythia Praxithea at Sanctuary of Delphi prophesied at the decree of the Cult of Kosmos that Kassandra's younger brother, the baby Alexios, would bring about the fall of Sparta. In order to prevent this, Alexios was to be sacrificed at Mount Taygetos, despite Myrrine's pleas for Nikolaos to stop it. As a priest was about to drop Alexios, Kassandra attempted to stop the sacrifice but instead pushed the priest and Alexios to their apparent deaths. Kassandra was condemned as a traitor to Sparta by the ephors, who urged Nikolaos to execute her immediately.
Nikolaos, being adherent to Spartan law, reluctantly complied and held Kassandra by her hand and dropped her down the mountain despite pleas from Myrrine. However, Kassandra survived the fall and escaped to the beach with the spear. Refusing to be found by the Spartans, Kassandra fled out to the open sea in a boat, with an eagle following her. A storm later turned Kassandra's boat overboard and she woke up on the beaches of Kephallonia. There, she was found by the merchant Markos, who took her under his wing.
Life as a misthios
Under Markos, Kassandra performed errands for him, occasionally helping him to settle debts that he owed. At one point, after cutting off the fingers of a boy who threw a rock at Ikaros, Kassandra befriended her neighbour Anais, who saved her from being beaten up by the boy's brothers. The two became close friends and were noted troublemakers on the island. Kassandra was greatly affected when Anais had to leave Kephallonia.
When she got older, Kassandra forged a career as a mercenary under the tutelage of such men as Photios and Heitor, and acquired misthios as her nickname on the island. It was during this time, circa 433 BCE, that she and Markos took in an Athenian orphan Phoibe as part of their 'family'.
By the early 430s BCE, Kassandra had set up home near the ruins of Kranioi on the western coast of Kephallonia, which she shared with Phoibe. From there, Kassandra habitually clashed with thugs and bandits working for the Cyclops, a bandit leader who sought to rule the island.
In 431 BCE, Kassandra was confronted once again by the Cyclops' thugs who gave her a bruised nose. After taking care of them, Phoibe stopped by, telling her that Markos requested to meet her at his newly-bought vineyard. Coming across Markos in his new property, Kassandra expressed her disbelief at his purchase of the vineyard even though he still owed her drachmae. Calming her with the promise of more, he directed her to collect from Duris, a merchant in Sami who owed Markos drachmae. In exchange for helping Markos to collect his debt, Kassandra convinced him to give her a horse, which she named Phobos.
Before Kassandra could depart, she and Markos were stopped by Euterpe, a farmer who informed them that Phoibe had been kidnapped by the Cyclops' thugs and was being held at Ktimene Beach. Making her way to the beach, Kassandra stealthily dealt with the thugs and freed Phoibe, who informed her that the Cyclops had hired the mercenary Talos the Stone Fist to kill her. Assured that Phoibe was alright, Kassandra then traveled to Sami to locate Duris and collect her debt. In doing so, she discovered that Markos had bought his vineyard with money he borrowed from the Cyclops. Once Duris had been dealt with, Kassandra returned to Markos at the Temple of Zeus, speaking to one of Cyclops' thugs. As Markos and Kassandra devised a plan to deal with the Cyclops, Drucilla, the town's bowyer, confronted Markos about her stolen lumber shipment. Kassandra later helped Drucilla to deal with her stolen lumber problem in exchange for having her bow fixed.
Afterward Kassandra returned to Markos, who then laid out his plan to repay the Cyclops by stealing his obsidian eye. Kassandra infiltrated the Cyclops' estate and stole the eye. Upon returning to Markos, he insisted she hold onto the eye before telling her that a group of bandits had arrived on Kephallonia. He believed the bandits were there to work with the Cyclops and suggested Kassandra deal with them. Before going to slay the bandits, she spotted a worried Phoibe asking her help to check on her friend that, supposedly was infected with a blood fever that was spreading in the Village of Kausos. Kassandra travelled to the place, encountering the family of Phoibe's friend ready to be executed by a local priest, who was afraid that they would infect the whole island. She decided to kill him and his followers to then free the family and let them go search for a doctor. At some point while running her errands, she killed the misthios that had been persuing her.
Odyssey through Greece
Working for Elpenor
Kassandra then went to an abandoned house the bandits Maykos had spoke off were squatting in and killed them all. To her surprise, the last bandit was executed by their real employer, a man named Elpenor of Kirrha. Furthermore, Elpenor stated he was looking for Kassandra and hired her to recover Penelope's shroud from Ithaka. She sailed to the island in a boat and found the item in possession of a bandit in the ruins of Odysseus' Palace. While there, she freed a woman named Odessa that claimed to be one of Odysseus' descendants, in pilgrimage, and scorted her through the ruins, until she had to sail away. Subsequently, Kassandra returned to Elpenor, who then hired her to assassinate a Spartan general nicknamed the Wolf in Megaris.
Requiring a ship to reach Megaris, Kassandra learned from the shipmaster Telemenes that the Cyclops had a ship and had returned to Kephallonia. Thus she confronted him in Kleptous Bay, interrupting him torturing a one-eyed man. After mocking the Cyclops by sticking his obsidian eye up a goat's backside and then killing him, Kassandra rescued Barnabas, captain of the Adrestia, who agreed to transport her to Megaris. After bidding farewell to Markos and Phoibe, who gave her Chara, her wooden eagle, Kassandra informed Barnabas of her contract and was surprised to learn that the Wolf was none other than her father, Nikolaos.
Arriving in Megaris after breaching a blockade, Kassandra met Stentor, the adoptive son of Nikolaos. As she asked to meet the general, Stentor hired her as a mercenary to fight the Athenians in the region due to the Peloponnesian War. She spent the next few months trying to earn the Spartans' favour by weakening the Athenian forces. In her time aiding the army, she discovered a mole witin the ranks supported by a rival mercenary, Hyrkanos, and later discovered that he had stolen supplies from the Spartans, blaming the Athenians for the act. She was then sent to Megara to kill him, discovering in the process the vantages of killing other misthioi. While in in the city, she met a blind Persian that wanted to see the wonders of the Greek world. Kassandra agreed to be his eyes, in exchange for his story and the promise of a hidden treasure. She also encountered Odessa again, near the Port of Nisaia, managing to help her heal her sick father and also stopppng a conspiracy for having her killed in order to steal her estate, later recruiting the woman to her crew.
After some time, Kassandra eventually succeded in killing the Athenian leader and, subsequently, defeated the Athenian army in a battle, becoming know as the "misthios with the broken spear". She finally confronted Nikolaos alone but ended up deciding to spare his life. Regretting to have thrown Kassandra as a child, Nikolaos decided to quit the Spartan army and revealed to Kassandra that he wasn't her father. Before leaving, he tasked Kassandra to find her mother for more answers, warning her to "beware the snakes in the grass". Kassandra returned to the Adrestia, tolding to Barnabas what had happened in the last months, when he proceeded to told her that a plague had spread through all the Island of Kephallonia, in part thanks to Kassandra's actions. She ended up tolding him to go to Pilgrim's Landing, Phokis, in order to meet her employer.
On June that year, the ship arrived in Kirrha, with Barnabas deciding to go to Delphi, while Kassandra would conclude her task. She met Elpenor and showed him Nikolaos' helmet to prove she accomplished her mission. As the discussion went wrong, Elpenor fled while his guards attacked Kassandra. She survived the encounter, deciding then to track down Elpenor in the surrounding region.
Uncovering the Cult of Kosmos
Going to the Sanctuary of Delphi to question the Pythia about her family, Kassandra met his companion again, who presented to her the historian Herodotos who seemed to have knowledge about the Spear of Leonidas. When she spoke to the Pythia, Kassandra discovered that the oracle was under the control of the Cult of Kosmos, who forced her to tell the prophecies they wanted. After being thrown out from the meeting, she forced entry in the Pythia's house, in the Chora of Delphi. Talking alone with her, Kassandra discovered that the Cult were having a meeting under the Sanctuary soon and that Elpenor was one of its members. She also told her that, without the ceremonial outfit of the Cult, she wouldn't be able to pass the Cult guards. Kassandra then went to the fort the woman had pointed to be Elpenor's hiding place, but ended up killing his decoy. Finding a note in his belongings, she discovered his true hideout, finally fighting and killing him. On his corpse, she found a mask, a robe and a strange shard.
With the mask and the robe in her possession, Kassandra went to the meeting of the Cult in the Sanctuary of Kosmos. In the middle of the room was a Pyramid composed of the same type of shards she had found on Elpenor and felt compelled to complete it. During the meeting, Kassandra stole some of their documents and listened to some of their conversations, learning that the Cult had infiltrated virtually all of Greek society: economy, religion, politics, arts, and sports. They even had Cultists in the Delian League and the Peloponnesian League. She also discovered that the Cult was hunting her family to control the bloodline. Suddenly, Deimos, the weapon of the Cult, entered the room, tossing Elpenor's severed head to the ground and stating the Cult had a traitor in their midst. To find the traitor, he tested the members with the Pyramid: his hand on one face, the accused's on another. When it was Kassandra's turn, the artifact showed them memories of their childhood. Kassandra realized that Deimos was his lost brother Alexios. Disturbed, Deimos decided to let Kassandra go and accused Epiktetos as the traitor, smashing his head against the pyramid and killing him. During the confusion, Kassandra took a shard of the Pyramid before leaving the hideout. Exiting the cave, Kassandra met Herodotos outside, who convinced her to join him in a trip to Athens for reporting to Perikles the information she had gathered but, before sailing to Athens, they would meet at Thermopylae to discuss a secret about her spear.
Before heading to the place, she found a doctor named Lykaon in the Chora of Delphi whose grandmother was the oracle that had sentenced Alexios to death as a baby. She helped him to free Praxithea from a kidnap in order to judge her for acts. While exploring a Temple of Artemis in Phokis, she found a member of the Daughters of Artemis, Daphnae, who challenged her to hunt the Kalydonian Boar, the legendary boar that dwelled in a plateau nearby. After going to its den, Kassandra emerged victorious from the hunt. After delivering its pelt to the huntress, she tasked her to hunt all the other legendary beasts throughout Greece, in order to earn the trust and protection of the Daughters.
Kassandra traversed the mountains surronding Delphi through the Cave of Kratos and met Herodotos at the Lion of Leonidas at Thermopylae, where her grandfather died during the Battle of Thermopylae. There, the two touched the Spear of Leonidas and relived the king's last memory during the battle. Understanding it was an artifact of an ancient civilization, Herodotos talked to Kassandra about an ancient complex on Andros island. Kassandra was convinced to visit the island: once there she was able to open the Isu-built gate with her spear. Inside, she found a mold corresponding to the spear and using the shard she took from the Pyramid, she upgraded the weapon. Leaving the Ancient Forge, she was confronted by her brother, who accused her of throwing him from Mount Taygetos when he was an infant. Kassandra tried to tell him the truth but his indoctrination by the Cult was too strong and he left his sister with a threat to stay out of his way. Kassandra returned to the Adrestia to tell to Herodotos what she saw and they began their trip to Athens.
Interfering in Athens politics
In July 431 BCE, Kassandra and Herodotos arrived in Athens, which was besieged by the Spartans. The population was tired of Perikles' strategy to wait behind the walls of the city until the enemies left. The politician and army general Kleon advocated a more aggressive tactic and many Athenians were ready to follow him. As Kassandra wanted information about her mother, Herodotus told her she should go to Perikles' symposium to gather information on Myrrine's whereabouts. Perikles, the Athenian leader, said she must help him with three tasks to be allowed into the Symposium.
The sculptor Phidias was targeted by the Cult of Kosmos and Perikles wanted him out of Athens for Phidias' safety. Kassandra escorted him to Seriphos and killed Brison, the man charged to kill Phidias. Kassandra also saved Metiochos, who was captured by thugs and left in his house to be killed by poisonous snakes. Kassandra discovered that the thugs were poor people manipulated by a mercenary to kill Metiochos. She found the mercenary and killed him. Finally, Kassandra helped rig the ostracization of Anaxagoras to be sure he would be exiled. After the vote, Kassandra met the philosopher Sokrates who questioned her about her choices.
After accomplishing her missions, Kassandra was accepted to participate in Perikles' symposium. Entering Perikles' Residence, she met Phoibe, who had left Kephallonia, working now for Aspasia, Perikles' lover. Entering the party, Kassandra spoke with Herodotos who introduced her to the guests of the symposium: the playwrights Sophokles, Euripides and Hermippos, the sophists Protagoras and Thrasymachos, Sokrates and Perikles' nephew Alkibiades. Speaking to Sophokles, Kassandra learnt that Euripides had heard about a Spartan woman who might have been Myrrine. After plying him with wine, she discovered that the woman went to Asklepios Temple in Argolis to save her son. He told Kassandra to speak to Hippokrates in Argos to learn more information. After giving some oil to Alkibiades, he advised Kassandra to search for the Spartan woman in Korinth and speak with the influential hetaera Anthousa.
Conversing with other guests, Kassandra met Aspasia. Learning about her mother, the hetaera told Kassandra to meet her friend Xenia on the island of Keos who might have more information. After that, Kassandra spoke to Perikles about the Cult of Kosmos and the threat they represented for Athens. Later that night, Kassandra left the party after saying goodbye to Phoibe.
Before searching for her mother, Kassandra helped the playwright Aristophanes to investigate Hermippos and discovered that he was a Cultist and killed him. She found another member of the Cult in Attika, the Master, who mistreated his slaves. Kassandra attempted to free one of the Master's slaves, and the Master agreed, if Kassandra killed a woman. She refused, and slew him instead. She also helped the general Demosthenes and Kleon to fight the Spartans who were camped around Athens. She was tasked by Kleon to find two of his men Heremos and Onomakles. The first one was dead but she saved the second before attacking the Spartan fleet, permitting Onomakles to sail to Mytilene.
Searching for her mother
When Kassandra left Athens, she decided to follow all the lead she gathered during the symposium. Arriving in Argos, she met the doctor Hippokrates, who was missing his notes. As he needed his notes to heal his patients, she went to Fort Tiryns but the notes were burnt. She escorted the doctor of the fort to Hippokrates as he had read the notes. After that, Hippokrates told her that when he was younger, he saw a Spartan woman who went to the Asklepios Temple to save her wounded son. Going to the Temple, Kassandra helped the priests. They all gave information on the elder priest Mydon who had cut out his own tongue. Going to interrogate Mydon, Kassandra surprised him with his lover and slave. The slave spoke for Mydon, explaining that the priest met Myrrine who tried to heal her son, but that the priests failed to save him. Chrysis, the priestess of Hera forced Mydon to cut out his tongue to prevent him to speak about the Spartan woman and her child. Kassandra understood that Chrysis made her mother believe that Alexios was dead to later abduct him.
Going to the Altar of Apollo Maleatas, she was attacked by Cultists, proving the link between Chrysis and the Cult of Kosmos. As the priestess of Hera kidnapped another baby, Kassandra confronted her. Chrysis explained that she rose Alexios as her son and tortured him into becoming the weapon of the Cult. She also explained that the mother fled to Korinth after that and that the Monger was sent to capture her. Chrysis proposed Kassandra join her family but she refused. The Cultist set fire to the altar with the baby inside allowing her to run away from Kassandra. While Chrysis fled, she was killed by her estranged son Dolops.
Arriving in Korinth, Kassandra made contact with Anthousa. She also met again Phoibe, who was sent by Aspasia to announce her arrival to Anthousa. The heteara accepted to give information on Myrrine if Kassandra helped her to kill the Monger, a member of the Cult who forced the hetaerae of the city to pay him. She helped Damalis and Erinna against the Monger's men. Kassandra also burnt one of the Monger warehouse to stop his smuggling but was trapped by the guards. As she fought them, she was assisted by the Spartan general Brasidas and defeated them. Brasidas explained to Kassandra that he was there to stop the Monger crimes as Korinth was an ally of Sparta. He agreed the Monger had to be killed, but stealthily. When the Monger arrived, he was killed by Kassandra, Brasidas with the help of Roxanna and Erina. After that, the Monger's remains were then displayed publicly by Kassandra and Anthousa at the theater against Brasidas' wishes. To thank her, Anthousa told to Kassandra that she sheltered Myrrine, who later left Korinth after winning a ship, the Siren Song.
Arriving on Keos, Kassandra infiltrated the Temple of Athena Nedousia the headquarters of Xenia the queen of pirates, who control the island. As she asked her information, the pirate demanded a payment. When Kassandra collected the money, Xenia revealed that Myrrine worked for her as a pirate for a time and renamed herself Phoenix. She later left the island sailing southeast to search another goal. Kassandra began a partnership with Xenia for finding treasures with maps that the pirate gave to her.
Returning in Athens during the Autumn 429 BCE, Kassandra witnessed the city being struck by the plague. As Hippokrates tried to save the sicks, she helped him to burn the bodies of the dead as the Followers of Ares impeached that, seeing this practice as sacrilegious. Going to see Perikles, she learnt from Aspasia that he was also ill. Speaking with the strategos, she understood he was really weakened and that Kleon would take his place as the leader of Athens. When she returned to Aspasia, Perikles' lover tasked her to find Phoibe who was missing after she sent her to find a ferry. Investigating around the Odeon of Perikles, she found a massacre. As she saw Phoibe being followed by guards of the Cult, she ran to save her but when she finished the fight the young girl was already dead. Mourning her friend, Kassandra placed Chara in Phoibe's hands. Joined by Sokrates and Hippokrates, she decided to go to the Parthenon to speak with Aspasia.
Arriving near the temple, they found Aspasia who searched Perikles. Kassandra announced her the death of Phoibe which shocked Aspasia. When they entered in the temple, they saw Deimos killed Perikles. As Kassandra tried to stop him, he ran away sending guards. Following that, Kassandra decided to leave Athens with Aspasia. As Kleon was the new ruler of the city and ordered that no one leave the city, Kassandra fought her way to the Port of Piraeus. Before leaving, she asked to Sokrates and Hippokrates will stay to give Phoibe a proper burial. On the Adrestia, Kassandra spoke to Aspasia about the clues she found on her mother. Aspasia said she knew someone named Phoenix on Naxos Island, so they set sail for the island.
Finding her parents
Arriving on Naxos, Kassandra learnt that her mother had become the Oligarch of the island. When they met, the touching reunion between the daughter and the mother was interrupted by attacking Parian forces. Kassandra and Myrrine killed the invaders with the help of Timo and Hektor. After that, Kassandra spoke with her mother about her fate after the night on the Mount Taygetos and explained that Alexios was alive but working for the Cult. They decided to fight the Cult together and save Alexios from its control. As Naxos and Paros were at war, Kassandra helped her mother to defend the island and weaken the power of Silanos, Paros' obligarch. Kassandra also stopped the propaganda against her mother made by the artist Lichas, who was paid by Silanos.
During a symposium, Aspasia warned Myrrine that men were sent to kill her. Kassandra killed them before they could and discovered they were from the Cult. On their bodies, she found a coded message with the seal of Paros, confirming that Silanos was a Cultist. Aspasia deciphered the message and informed Kassandra that one of the Two Kings of Sparta was a Sage of the Cult. Myrrine was shocked as Sparta always resisted the Cult. The Archon decided to go to Sparta after the conflict with Paros was over. As the fleet of Paros had blockaded the harbor of Naxos, Kassandra destroyed the fleet with the Adrestia. After that she sank the Amber Dawn, Silanos' ship, killing him in the process and assuring the victory of the Spartans. Arriving in Naxos, her mother decided to return in Lakonia and fought the Cult. Kassandra agreed to join her. Before leaving Myrrine revealed to her daughter that her biological father was last seen in Thera and that she needed to see him. The two promised to reunite in Lakonia.
On the volcanic island of Thera, Kassandra found the Minoan Ruins and a gate like the Ancient Forge on Andros. Using her spear, she opened the gate and explored the underground of the island. Arriving in an Isu temple, she saw her real father Pythagoras greeting her. He explained to her that she was in the ruins of the legendary Atlantis which contained powerful knowledge. He told her that she was conceived to perpetuate an ancient bloodline and that her destiny was to help him to protect Atlantis from the Cult of Kosmos. For that, they needed to seal the Atlantis with four artifacts which were hidden around Greece. Kassandra accepted to help her father in his quest.
Tracking the Sage-King
Around 428 BCE, Kassandra joined her mother in Lakonia and the two went to Sparta. They first went to their old home to take it back but Brasidas informed them that the city claimed it after Nikolaos' disappearance. As Kassandra wanted to see the Kings, Brasidas advised her to deal with the Helots revolt in Sparta to be sure that the rulers will listen to her. After that, Kassandra and her mother met the Kings Archidamos and Pausanias of Sparta. As Archidamos was furious against Myrrine and Kassandra after what happened on Mount Taygetos, Pausanias proposed that the misthios proved her loyalty. Archidamos tasked her to conquer Boeotia while Pausanias demanded her to escort the champion Testikles to Elis and assured the victory of Sparta during the Olympic Games. After the meeting, Brasidas informed Kassandra that he had a lead on a Cultist in Arkadia. Myrrine chose to follow Brasidas while Kassandra would accomplish the Kings' tasks. Before her mother departure, Kassandra promised to join them in Arkadia. During her time in Sparta, Kassandra met the General Lysander who tasked her to find Polemarch seals from Athens.
Escorting Tesikles on the Adrestia from Sparta to Kyllene, Kassandra accidentally made the champion fall into the sea to be eaten by a shark. Alkibiades who was there proposed that Kassandra replaced Testikles for the Panchrates. Arriving in the Sanctuary of Olympia, Kassandra participated in the rituals of Olympic Games with Barnabas. During the competition, Kassandra defeated Orion and Erastos which qualified her for the final. While she celebrated her first victories, Alkibiades collapsed after he returned from a party. As Barnabas supposed he was poisoned, Kassandra investigated the case. She discovered the corpses of other Athenian guests and was attacked by a guard of the Cult. Interrogating the merchant Priam she learnt that someone pay him to poison the wine. She went to Fort Koroibos to find an antidote. Returning to Alkibiades, she saved in time the young man.
During the final, Kassandra fought the champion Dorieus and won the competition. Receiving an olive wreath, Kassandra was announced as the Olympic champion. In Olympia, she discovered that the champion Kallias was the Cultist who poisoned Alkibiades. She killed him and collected more information on the Sage of the Peloponnesian League. She also met Phidias who was target by the Cult. He told her that he received a scytale and a note. On the note they discovered a riddle that led to Temple of Zeus in Olympia. There Kassandra found a symbol for decoding the mysterious message. Phidias told her to find the others on three other statues in Kythera Island, Samos, and Thasos. Kassandra agreed to accomplish this quest.
After travelling to Lokris and finding a note stating that funds were donated by the Abantis Islands to the nation, Kassandra learned of Skylax, the Spartan leader of the islands and another member of the Peloponnesian League branch. To find a little more information on the Sage, Kassandra killed him. 
In Arkadia, Kassandra was attacked by the misthios Sosipatros who was after a bounty on her head. After she defeated him, she learnt that this was the Spartan Archon of Arkadia, Lagos, who had placed the bounty on the heads of her and her mother. Joining her mother and Brasidas, Kassandra understood that Lagos was a member of the Cult. Myrrine wanted him dead while Brasidas suspected that the Cult had forced Lagos' hand. Then, Kassandra aided Brasidas in his investigation about Lagos' motivations. She later discovered that the Cult had kidnapped his family and, after finding them caged on a hideout of the Cult, she released them from their custody. To low the bounty on her head, Kassandra weakned Lagos' control over Arkadia. She then went to Fort Samikon to confront the archon. When she found him, Lagos presented her with documents that proved that Pausanias was the Sage. She then convinced him to leave the cult, reassuring him that Brasidas would protect him.  With all the members of the branch defeated, Kassandra gained the Spartan War Hero Armor. After dealing with Lagos, Kassandra came back to Brasidas and Myrrine to tell them of her findings. Then, she decided to aid in the war against Athens in Boeotia before returning to the kings.
In 427 BCE, Kassandra arrived in the Spartan Military Camp in Boeotia to help their general but she discovered that it was Stentor. He accused her to have killed Nikolaos and was angry that the Kings sent her to help him. He ordered Kassandra to kill the four Champions of Boeotia who worked for Athens. She killed Drakon and Nesaia. She discovered that the champion Deianeira was a Cultist, so she killed her and her cousin Astra to avenge the death of Timon's brother Abreas.
While she prepared to assassinate the champion Aristaios, she saw Nikolaos fought and kill the champion. Discussing with him, he explained to her that he helped Stentor in the shadows to repair the wrong he did to his family. Kassandra convinced him to reunite with Stentor. As she accomplished her mission, Kassandra joined the Spartan troops and defeated the Athenians on the battle ground. After their victory, Stentor dueled Kassandra for avenging Nikolaos' death. However, before it could start Nikolaos appeared to separate his children, the fight was over. Nikolaos calmed his son and asked him to lead his men. Before she left, Nikolaos wished that the gods watch over Kassandra and her mother.
Returning to Sparta, she confronted the Sage before Archidamos, the ephors, the Gerousia, and the Hippeis, which charged Pausanias for his crimes. As Kassandra made a great service for Sparta in addition to accomplish the Kings' quests, Archidamos granted Kassandra and Myrrine to live in their house. After Pausanias' exile, Kassandra tracked him down and slew him. She found a letter from the Ghost of Kosmos, the leader of the Cult, saying they planned to trick the misthios to believe that Archidamos was the Sage of the Peloponnesian League and ask to Pausanias to unite the Greek poleis under their command.
Fighting the Sage of the Delian League
When Kassandra and her mother entered their house, Brasidas came to ask help from the misthios to prepare an attack against the Athenians in Pylos as they were rumors that Deimos was on their side. She accepted and went to Messenia. In Summer 425 BCE, the two armies battled for supremacy. During the fight, Brasidas was wounded by Deimos who then attacked Kassandra. The duel came to a stalemate after a burning tree fell of Deimos and later Kassandra, rendering them both unconscious. The Athenians subsequently won the battle, and Kassandra was captured by Kleon and brought to a prison in Athens.
Waking up, Kassandra met with Deimos observing her outside the cell. While she discussed with her brother, Kleon entered and revealed he was the Sage of the Delian League and ordered the murder of Perikles. He then left while his guards attacked Kassandra in her cell. She defeated them and met Barnabas and Sokrates who broke into the prison to save her. They gave her equipment and together went to Perikles' Residence. Together with Aristophanes, Alkibiades, Herodotos and Hippokrates they formed the Periklean Circle, a group dedicated to dimish the power of Kleon and bring back Democracy in Athens.
With Sokrates, Kassandra exposed Kleon lies on the revolt of Mytilene before Athens citizens. She also help Aristophanes by protecting the actors Thespis and Aikaterine who were targeted by the Cult as they played in The Knights which criticized Kleon. In the process, Kassandra killed the Cultist Rhexenor. With that, the popularity of Kleon decreased and he was forced to fight the Spartans led by Brasidas in Amphipolis to regain some reputation. Kassandra decided to join Brasidas to fight Kleon.
In Summer 422 BCE, during the Battle of Amphipolis, Kassandra saw Brasidas being killed by Deimos. As she confronted her brother, the duel was short as Alexios was hit in the back by an arrow shot by Kleon who targeted Kassandra. Angry, Kassandra racked the Sage who ran away from the battle. After a fight, Kleon tried to convince Kassandra to join the Cult but she killed him. On his body, she found a letter from the Ghost which proved that the leader of the Cult organized the death of Perikles and asked Kleon to unite the Greek cities under their control. Returning on the battlefield Kassandra didn't find the body of Alexios.
Reuniting her family
Returning to Sparta, Kassandra told her mother what happened in Amphipolis and the undetermined fate of Alexios. Going to Mount Taygetos where it all begun, Kassandra and Myrrine saw Alexios near the cliff. They tried to reason with him to leave the Cult and rejoin his family, but he had lost the will to live and said that he couldn't be what they wanted him to be. Tired of reasoning with him and resentful of his actions towards her friends and family, Kassandra realized that her brother was beyond saving. In a desperate move, Alexios feinted towards his mother with a blade, forcing Kassandra to fight him and kill him. She recovered his sword and his armor. She also found a letter from the Ghost of Kosmos which proved that the leader of the Cult manipulated all the cult members against each other.
After the tragedy of losing her brother, Kassandra organized a dinner in her old house with her mother, Nikolaos and Stentor.
Kassandra also returned to Perikles' residence to celebrate with the Periklean Circle their victory over Kleon and the Cult, remembering Kassandra's adventures and paying tribute to their fallen friends during the War. The Athenian general and politician Nicias, who was a member of the Circle, engaged with Sparta for the proposal of a peace.
During her journey, Kassandra also searched the fragments of Atlantis. Pythagoras gave her the half of a medallion of the Isu and advised her to go to Boeotia to meet his ally Gorgias. Meeting him at the Lair of the Sphinx, he informed her that his apprentice Pibos had the other half of the medallion but he was missing. Searching him, Kassandra found Pibos dead, devoured by a lion. Understanding that the lion ate the medallion's other half, she hunted the animal and killed it.
Completing the medallion, Kassandra returned to the camp and saw that Sphinx's statue disappeared and that Gorgias was dead. She inserted the medallion in the lair but nothing happened. She returned the night to retry and a giant Sphinx appeared. The creature told to Kassandra that she needed to solve three riddles to have the artifact. If she answered wrongly, she will die as Gorgias. Answering the three riddles and activating the corresponding symbols, a flash a light killed the Sphinx. Kassandra took from its body a glowing feather which turned in a metallic sphere and the creature took the form of a decayed human corpse.
Investigating on another artifact on Kythera Island, Kassandra was tasked by a man to save Empedokles, a supposedly living god who was captured by the priestess of Aphrodite. As she saved him, Empedokles proposed to Kassandra to join him to Olympos to see the gods. But as the key was stolen, he tasked her to find the thief. When she recovered the key, she discovered that it was another medallion key.
Reuniting with Empedokles on the Isle of Thisvi, Kassandra opened an Isu gate. In the cave resided the Cyclops Brontes, who killed Empedokles by smashing him. Kassandra fought the giant and killed him. Like with the Sphinx, when she took the eye of the creature it turned back into a spherical artifact. During other travels, Kassandra fought and killed two other Cyclopes, Steropes on Andros island and Arges in the volcanic island of Nisyros.
In Krete, Kassandra went to the ruins of Knossos Palace. There, she found a boy, Ardos, who tried to find his father Nikios who disappeared while exploring the labryrinth under the palace. The boy showed to Kassandra the entrance under the palace. She agreed to help Ardos to find his father interrogating the three men who accompanied Nikios. Interrogating the Collector, she learnt that Nikios, the Swordfish and him tried to kill the Minotaur using Theseus' armor for protection. As they were afraid of the creatures, they fled but left Nikios behind. He gave a part of the armor to protect Kassandra and explained where were the other parts. Searching for the Swordfish, she learnt that he was a criminal who controlled Herakleion but was also a member of the Cult. When she found his hideout, the Swordfish believed that Kassandra was Deimos. He revealed to her what happened in the Labyrinth and that Nikios was dead. As he wanted to quit the Cult, the Swordfish attacked Kassandra but he was killed.
As she searched for Ardos' caretaker, Kassandra fell in a trap of the Cult but defeated them. She rescued the captured caretaker. He explained that he had the key of the Labyrinth but that Ardos stole it. Returning in the ruins, Kassandra spoke to the boy who gave her the key. With the Theseus armor, she entered in the labyrinth and faced the Minotaur. After killing the monster, she broke one of his horns which transformed into a spherical artifact like the ones before it. She left the labyrinth, giving Ardos his deceased father's ring and bid him farewell.
On Lesbos island, Kassandra witnessed a woman named Bryce cornered by an angry mob who accused her of making a sacrifice for the Writhing Dread. She explained to Kassandra that she lost her lover Ligeia during their hunt of the creature. Kassandra accepted to help her saved Ligeia and went together to the Dread Ruins. There, they found the Petrified Temple closed. As they needed the key to open it, Kassandra went to the village of the Daughters of Artemis on Chios and recovered the key.
Kassandra also interrogated Zetes the Retired, a misthios who claimed to have killed the creature. He explained that he was paid by the Cult to recover an artifact and that he killed the monster with his spear after it killed his friends. As Kassandra needed his weapon, they fought and Zetes died. On him, she found a letter explaining that it wasn't Zetes but Ligeia who killed the Writhing Dread but when she touched the artifact, she transformed into the creature herself.
Returning to the Petrified Temple, Kassandra entered with Bryce in the Isu complex. When they were before the Writhing Dread, Bryce was petrified by the monster. Kassandra fought the creature and killed it before taking a snake on its head which was in fact the Prize of the Medusa. She paid respect to the petrified Bryce before leaving the Temple. After that, Kassandra met a woman who claimed to have created an elixir to reverse the effect of petrifaction, however, it was a lie. As she tried to kill Kassandra, the misthios returned the favor.
Returning to the Gateway to the Lost City, Kassandra put the artifacts in the pillars. When she activated its, the records of the Isu were hacked by the Isu Aletheia who spoke about the First Civilization, the Olympos Project, the Human-Isu War and the Great Catastrophe. The Isu also asked Pythagoras to pass the Staff. In her last message, Aletheia spoke directly with someone who wasn't there.
After that, Kassandra asked Pythagoras how they will seal the Atlantis. He said that the Staff of Hermes Trismegistus could but that he needed to learn all the knowledge of the Isu to change the World. As Kassandra saw that her father turned away from his goal, she tried to convince him to abandon his pride and to save humanity as the Cult of Kosmos could discover the secrets of the Atlantis. After an argument, Kassandra received the Staff which killed Pythagoras instantly due to his age. Paying respect for her father, Kassandra sealed the Atlantis with the Staff. Returning to the Adrestia, she made Herodotos and Barnabas promise to never talk about the Atlantis to anyone.

Even with Kleon's death, the Delian League branch continued to work. Kassandra received a letter from Kyra to help her and the Spartan Thaletas to lead the rebellion against the ruler of the Silver Islands Podarkes, who was a member of the Cult. Arriving in Mykonos, she accepted to help them but discovered that Podarkes was Kyra's father. Regardless, she killed him, liberating the islands. That night the island celebrated their liberation, Kyra also gave her father a proper send-off. On Chios, Kassandra was hired by the merchant Thais to kill Kodros, the corrupt leader of the Petrified Islands. Finding out he was a Cultist she killed him. Arriving on Lemnos, Kassandra was contacted by Mikkos, the caretaker of Barnabas' nephew Neleus. As the young man was sicked, he asked her to help him. Investigating, she discovered that the leader of the Hephaistos Islands and Cultist Iobates poisoned him as he knew about his plan to create an army of ferocious mercenaries with the athletes of Thasos. Kassandra killed Iobates in the Ancient Stronghold, freeing the Hephaistos Islands. With all the branch members killed, Kassandra continued her vengeance.
On the Adrestia, Kassandra explored the seas to hunt down the members of the Gods of the Aegean Sea. She sank the ships of Asterion, the Octopus and the Mytilenian Shark. During the naval battle for the conquest of the Obsidian Islands, Kassandra attacked the Eos, the ship of the Cultist Sokos, and destroyed it. In Messara, Ptolemaios hired Kassandra to kill the leader of the region. When it was done, she discovered that the leader's son, Melanthos, was a Cultist. She located him and sank his ship the Kronos. With all the fleet destroyed, Kassandra located their Sage the Hydra near the coasts of Messenia. She attacked his ship the Hyperion. When she killed him, she discovered that the Ghost was a woman via the Cultist's note.
Traveling around Greece, Kassandra tracked the members of the Worshippers of the Bloodline. She killed Zoisme and the leader of the Followers of Ares Harpalos. On Kythera, Kassandra was contacted by Diona who told her that the Cult wanted to take over the Island. She helped her but discovered that she was a member of the Cult who wanted to kill her twin sister Eritha to become the High priestess of Aphrodite. She killed her ending her plot. In the region of Pephka, she met Leiandros who claimed she could fight the Minotaur and gain a large sum of drachmae. After three pre-trials which were tourist trap, Kassandra could enter the Minotaur's cave. She discovered that Leiandros disguised himself as the creature to scare the tourists but that it was forced lately by the Cult to doing as his daughter Amara was kidnapped. Kassandra saved her and learnt that it was the plan of Melite, a Cultist. Kassandra killed him in Kydonia. Kassandra then located the Sage Iokaste on Chios. She infiltrated the Anavatos Ruin and killed her. Via the note correspondence, she discovered that the Ghost used religion to manipulate the Greek population.
The Heroes of the Cult branch was the armed fist of the Cult. Kassandra killed Okytos in Attika. While trying to become the new champion of Pephka Arena, she dueled and killed Belos, the Beast of Sparta. During the conquest of Achaia, Kassandra fought Pallas on the battlefield and killed him.

With all the fragments of the Cultists, Kassandra upgraded the Spear of Leonidas to its maximum.
With all these clues and only the Ghost remaining, Kassandra returned to the Sanctuary of Kosmos to confront the Ghost. She only found the Pyramid and when she touched it, she had a vision of Pythagoras from the past. He was in the Sanctuary speaking directly to her. He explained that the Cult of Kosmos was once a part of the Cult of Hermes, which worshipped the balance between Order and Chaos, but that the members of Kosmos began to prefer Chaos and used it to have control over Greece. He said that her destiny was to destroy the Cult and as she succeeded, she would be a hero. But in tandem, without Chaos, another group will impose Order without freedom. He reassured her that there still hope in a faction inspired by her. He finished saying that the world needed her and she saw a last vision from a distant future of her passing the Staff to another woman.
When it was finished, Kassandra saw in the Sanctuary Aspasia who revealed she was the Ghost. She explained that she lost control of the Cult over Deimos and that she was against the goals of the other members as the War began to be out of control. When she met Kassandra, she understood she could end the Cult. She also revealed that she saw a vision of the future with the artifact: Kassandra destroying the Cult and the Pyramid, the creation of a rational and perfect society under a philosophical king. As Aspasia wanted to create this new republic, she asked Kassandra to join her. She refused but let Aspasia left the Sanctuary alive. When Kassandra saw the Pyramid, she destroyed it with the Spear of Leonidas before leaving the place.
Fighting the Order of the Ancients
During her odyssey, Kassandra received a letter inviting her to go to Potidaia in Makedonia as a huge force attacked civilians. Arriving there, she witnessed the village burning by Spartan soldiers who took the villagers hostage. Kassandra killed the soldiers, saving Aiantides and the other villagers. As she searched for other hostages, she was taken by surprise by a soldier but was saved by a persian archer. After that she was confronted by a masked man and Persian soldiers. She killed the soldiers but the masked man escaped. Later, she met the man who saved her, Natakas, and helped him to save other villagers. He explained that these men knew her and obeyed for the Huntsman. While Natakas decided to stay with the civilians, Kassandra tracked the masked man.
On the road, Kassandra found the bodies of Spartan soldiers and the masked man, dead. As she inspected the body, she was attacked by an old hooded man with a strange blade. The fight finished when Natakas interposed, as the hooded man was his father and told him that Kassandra was the Eagle Bearer. As the two men left, Natakas told her to join them to their hideout below the Rock Arch. There, the mysterious man explained everything: he was Darius, the man who assassinated the king Xerxes I of Persia three decades ago. The king was manipulated by the Order of the Ancients, a secret society that seeked to impose order in humanity by force. He told to Kassandra that Natakas and him flew the Order since the death of the king and that she was also tracked by the Huntsman, a member of the Order who lured Kassandra in Makedonia to kill her as she was a Tainted One. He offered her the choice to leave or fight the Order, Kassandra agreed to fight back.
Hunting the Hunters
Darius explained to Kassandra that the Huntsman was the Magus of the Order of Hunters, a branch of the Ancients. They decided to track him by eliminating his lieutenant. Kassandra hunted a boar with Natakas and discovered more on his family, that was killed by the Order. Talking with Barnabas, she explained the situation to her first-mate. With Natakas, Kassandra investigated on the plague which stroke the village of Potidaia. As the Magistrate of the village didn't do anything, she helped the healer Timosa who was attacked by the Magistrate's guards. The healer asked her to found medicine on ships took by pirates. Kassandra boarded them but found that they weren't pirates but Persians. Returning in Potidaia, Natakas informed her that the village was poisoned. Kassandra understood that Timosa was the one who did that as she was a Hunter. After a fight, she killed the Ancient.
Working with Darius, Kassandra tracked the Conspirator who recruited men for the Order. She infiltrated Olynthos Fortress and discovered an encoded note of the Conspirator which prepared a meeting near the farms the night. Kassandra and Darius awaited him and killed the Conspirator. In the fort Kassandra also discovered that Akantha, the wife of the ruler of Makedonia, was a member of the Order. She tracked Akantha and killed her.
Kassandra tracked the other members of the Order. She killed Phratagounè who kept the beasts of the Huntsman. She also killed Konon who worked with the Followers of Ares. Investigating on a villager who survived an attack from the Magistrate of Potidaia and she discovered that he joined the Order to take his revenge. In his camp, she found a note on Echion, the Ancient who hired Hylas. She found the Ancient and killed him. She also killed Hylas who stole the secret stash of the Magistrate. Kassandra hunted the wolves of the Huntsman who attacked civilians near Amphipolis.
Natakas sent Kasandra to find one of his informants in the Swamps of Thermes. Finding a camp, she freed a woman who informed Kassandra that her young son worked for Natakas but was captured by the Ancients. Searching him in the fog, Kassandra found the child who was afraid that she killed him. Following him, she found a tree with the hanging corpses of the men she killed in Potidaia. There she was confronted by a masked man who told to not trust Darius as he wasn't what he pretended to be. He also wanted to show her the chaos she provoked with all the persons she killed, as their relatives confronted her near the tree. The masked man fled but left a message where it was written that the Huntsman waited in the forest.
Meeting with Natakas, Kassandra collected all the information she gathered on the Ancients and localized the Huntsman. In the forest, she saw the Huntsman, who was the masked man in the Swamps of Thermes. He told her that as a Tainted One, she was dangerous for the world and that his duty was to kill her and Darius. Kassandra fought the Huntsman and his men. The Ancient flew in a cave where Kassandra tracked him and mortally wounding him. When his men tried to kill Kassandra, Darius and Natakas arrived in the cave and killed them.
In his last breath, the Huntsman revealed the truth: his real name was Pactyas and Darius was Artabanus, his old friend. Together with their friend Amorges, they planned the assassination of Xerxes I to protect Persia from the Ancients. After the death of the king, Amorges and Pactyas though that allying with the Ancients could bring peace in Persia while Artabanus decided to kill the young king Artaxerxes I of Persia as he was a puppet of the Ancients. As Amorges was against the murder of an innocent, he protected the king from an assassinating attempt by Artabanus. Artabanus was branded as a traitor and tracked by the Order leading to the death of his family.
As Pactyas died, Darius confirmed it was the truth and buried the corpse of his old friend. Later, Kassandra met again in Darius' hideout where she saw the old man and his son prepared their leaving as they knew that Amorges will track them after the death of Pactyas. They bid farewell and Kassandra promised to fight back the Ancients if they tracked her.
During her time in Makedonia, Kassandra saved Ide, a friend of Natakas who was imprisoned in military camp. She explained to Kassandra that she was angered that the Order hired mercenaries who patrolled around her drinking spot. Kassandra offered to kill the three mercenaries while Ide promised she would share a cup of wine with her for that. After killing Agis of the North, Gaia the Fist, and Theos the Stargazer, Kassandra returned to see Ide. At the drinking spot, she discovered that Ide had been killed by a fourth mercenary, Exadios the Backbreaker. After toasting with a cup of Ide's wine, Kassandra killed the mercenary to avenge the old lady.
Returning in Potidaia, Kassandra found a letter from Aiantides who wanted to reward her for saving him during the attack of the village. Kassandra followed his instructions and collected the reward. Later, Kassandra found another letter from Aiantides who wanted to pay his debt to the misthios as she had saved his brother at the farm during the ceremony led by the Conspirator. Kassandra recovered the treasure.
Fighting the Storm
Sometime later, Kassandra received a letter from someone asking her to meet him at Dyme in Achaia. Arriving there, she discovered that it was Darius who sent the letter. He informed her that Natakas and he took refuge in Achaia but that the Ancients found them. Natakas tried to secure a boat to escape from the blockade in Patrai but he never returned. Together, Darius and Kassandra searched Natakas and killed guards who tried to kill them. As they met Natakas, he informed them that the Ancients captured civilians and imprisoned them in the Teichos of Herakles. Kassandra decided to liberate the prisoners.
In the fortress, she found a letter that proved the connection between the Cult of Kosmos and the Order of the Ancients. She liberated a man, the mother of a girl Natakas found and Kleta. Returning to Darius and Natakas, Kassandra discussed with Kleta who informed them that Achaia was under the control of the fleet of the Tempest, the Magus of the Order of the Storm, a branch of the Ancients. As Natakas wanted to help the people of Achaia, Darius accepted to fight the Ancients which could permit them to leave the Greek world. Kassandra decided once again to join the father and the son in their fight against the Order.
With the note of the Cult, Kassandra collected other pieces of information on the Tempest, learning she kidnapped the civilians of Boura and prepared a weapon for her ship. Going to Boura, Kassandra met again Kleta who helped the stranded peoples to leave Achaia. Kassandra offered her help and Kleta sent her to the merchant Orontas. As they discussed their plan to recover Orontas ships, guards of the Ancients arrived. After Kassandra killed them, she joined Kleta and Orontas planning to make a deal with Ariston, the foreman of the docks of Pellene. Before leaving, Kleta revealed to Kassandra that the Tempest was her daughter Phila. Arriving in Pellene, Kassandra succeeded to make a deal with Ariston to take back Orontas' ships. At this moment guards arrived to arrest the responsible for the stranded release. Orontas took the blame to protect Kassandra and Kleta.
Kassandra received a letter from Aiantides, who wanted to thank her for killing the Huntsman. He indicated to her the location of his last gift on Achaia shore. Collecting it, Kassandra met in person Aiantides who thanked her for liberating his aunt at the Teichos of Herakles. As he had no other gift, he claimed that he owed a favor to Kassandra. After she asked him many favors, like killing the Tempest or joining her crew, but Aiantides refused. Kassandra decided to let him go even if Aiantides still claimed he had to redeem his honor.
During her hunt, Kassandra tracked the Ancient known as the Broker. On a shipwreck, she found on a corpse a manifest indicating that the Broker was Sophos, a wealthy shipwright of Patrai who funded the Ancients. Kassandra assassinated him and found on his body a letter from the Ancient Nestor, the captain of a ship that patrolled the waters of Achaia to blockade the region. On the Adrestia, Kassandra boarded the ship of the Ancients and killed Nestor. Another letter led Kassandra to his next target, Augos, who monitored Darius and Natakas. Kassandra went to the Shipwreck Cove and assassinated Augos.
Returning to Patrai, Kassandra joined Natakas and spied on the Tempest, testing a new fire weapon for her ship, the Skylla. As the weapon exploded and the Ancient left, Kassandra and Natakas investigated in the city to find her. After attacking Tempest's mercenaries, they interrogated one of them who revealed that the Tempest locked down Achaia to kill Kassandra. With the Adrestia, Kassandra destroyed a part of the Tempest's fleet.
Later, Kassandra met Darius in his hideout the hull of an unfinished ship in Patrai. As Gyras, the Tempest's chief engineer wanted to flee Achaia, they decided to interrogate him. At the amphitheater, the engineer revealed that his new weapon, the Chimera's Breath, wasn't complete. He accepted to install it on the Adrestia if Kassandra recovered the cyphered plan which was under guard. After recovering the plan, Kassandra discovered that Gyras was killed by Megakreon, an Ancient. As she was ambushed, Darius helped her to defeat the guard and killed the Ancients.
After, Kassandra met Darius, Natakas and Kleta to organize their plan: Kassandra will attack the Tempest's fleet while Darius, Natakas and the stranded evacuate Achaia. During the night, Kassandra and Natakas went into an empty house at Dyme. While drinking, they spoke about their difficulty to make friends and remembering their time in Makedonia. The next day, as Kassandra bid farewell to her friends, the Tempest and her fleet approached to stop the evacuation.
With the Adrestia, Kassandra sank the Skylla and confronted the Tempest who dragged herself on the shore. As the Tempest swore to kill Kassandra as she was a Tainted One, Kleta arrived and revealed to her daughter she was herself a Tainted One. A duel between the two Tainted Ones occurred, resulting in Kassandra killing Phila and ending the Order of the Storm.
Founding a family
After the destruction of the Order of Storm, Kassandra was ready to bid farewell to Darius and Natakas, but they ultimately chose to stay with her in Achaia. Taking the empty house in Dyme as home, they formed some kind of family, Kassandra and Natakas having a son, Elpidios. While raising her son, Kassandra resumed her work as a mercenary, obliging her to leave her family from time to time.
Later, Kassandra discovered that, before dying, the Tempest recruited mercenaries to kill her. Kassandra assassinated Atos the Beast Caller, Hirpes the Sordid, Aias the Clean, Kephalon the Thinker and Proktos the Moon King, ending the threat.
Returning to Achaia after a contract, Kassandra slain boars to protect Dyme and used the meat for Darius' gathering. Joining Darius, she discovered that Natakas and Elpidios played hide and seek on the beach. Kassandra and Darius intervened in their game, finding Natakas and Elpidos. After some time with her son, Kassandra collected shellfish with Natakas while Darius took Elpidios to prepare the feast.
During their time together, Kassandra and Natakas spoke about their son and the impact he had on their lives. Near a cliff, Natakas showed Kassandra a charm that his mother gave him to protect him. He threw it in the water, proving he trusted her to protect the family. At the night, Kassandra shared a diner with the others before Natakas put Elpidios to bed. She reflected with Darius on the peaceful life they had.
Searching her son
During their conversation, Kassandra and Darius spotted smoke over Dyme. They ride to the village, discovering it was attacked by the Order of the Ancients. Kassandra was welcomed by Orontas but Darius revealed that Orontas was Amorges. After fighting soldiers of the Ancients, Kassandra and Darius joined Natakas and Elpidios. Darius decided to attack the Ancients to give time to the three others to leave. Before leaving, Kassandra promised to Darius to protect their family.
On the way to the beach, Kassandra protected Natakas and their son, killing soldiers of the Ancients. While preparing a boat to leave, Kassandra decided to save Darius, leaving Natakas and Elpidios on the shore. As Darius was about to be killed by the Immortals, Kassandra intervened saving Darius and killing the two Ancients. Realizing that the attack was a diversion, Kassandra and Darius returned to the shore only to find Natakas dead and no trace of Elpidios.
The next day, Kassandra and Darius buried Natakas in their house. Darius reproached Kassandra to break her promise to protect their family. When Kassandra proposed to work together to find Elpidios, Darius left to find him alone. On the grave of Natakas, Kassandra promised to find their son. Talking with Barnabas, she discovered that the ballistae used by the Ancients were created in Messenia. With no other lead, Kassandra took the Adrestia to find her son.
Arriving in Aipeia, Kassandra discovered that many guards of the Ancients were assassinated. Investigating the area, she was ambushed by Darius. Sharing his information, Darius revealed that Messenia was the stronghold of the Order of Dominion. Having the support of the Spartan Army, the Order also had a large production line for their weapons, One of their commanders supervising the helots. He also spoke about the Ancient Dimokrates who tried to negotiate reinforcement with the Cult of Kosmos. Finally, he told to Kassandra that an Athenian General was captured by the Order, but if he was freed, he could help them. Kassandra reluctantly decided to work with Darius.
Going to the Leader House, Kassandra freed helots to learn the identity of the commander working for the Order of Dominion. She saved the helot Rhode who would be executed. The helot accepted to lead her to the commander if she helped her to free her son Pebble and other helots' children. With Rhode and the children, they were blocked by the commander Harpagos. Kassandra killed him and his guard, founding a letter of the Magus of Dominion indicating to maintain the helots under the control. After this, Kassandra joined Rhode and the children and must choose between sending the children out of Messenia or not.
Joining Darius, Kassandra began to track Dimokrates. As they didn't what he looks like, Kassandra eavesdropped on a meeting between the Order of the Ancients and the Cult Of Kosmos. Identifying Dimokrates, she killed him and found a letter from the Magus, indicating the uneasy alliance between the Order and the Cult.
In the Spartan camp, Kassandra freed the Athenian General and his soldiers. After giving Darius' letter, the General accepted to help Kassandra against the Order if she sank the Spartan fleet near Messenia. Destroying the fleet, Kassandra recovered on the commander a letter from the Magus, indicating that the Order supported Spartan Army.
During her track, Kassandra found a letter from Amorges demanding respect for his soldiers sent to Aipeia. She killed all the soldiers. She also rescued once again Aiantides who was captured by the Ancients. She let him choose between working for her on the Adrestia or leaving.
Meeting up with Darius to prepare the last step of their plan, Kassandra received a letter from the Order inviting her to go to the graves of Aipeia. Going there, She encountered Gergis, Magus of the Dominion and herald of the Order. He told her about the goal of the Order and why they tried to kill her as she brought chaos. While admiring an island near the coast of Messenia, he proposed to tell her how Natakas die and even let her decide if she could kill him or not.
While the Athenians prepared their attack against the Spartans, Kassandra and Darius set fires in Aipeia to force the helots to flee, drawing the attention of the Ancients. After killing the guards, Kassandra interrogated a soldier who informed her that the Order's headquarters was in the Andania Mine. As the Athenians were slaughtered by the Order, Darius attacked them while Kassandra went to the mine. As she found the archives of the Order, she was attacked by members of the Ancients she defeated.
Reaching the Temple of Zeus, Kassandra confronted Amorges to get back her son. As she told him she will destroy the Ancients, Amorges replied that the Order had already infiltrated the Greek society and will bring peace to the World, but the only obstacle of this was her. As Darius arrived, the two fought Amorges as he refused to give back Elpidios. During the fight, Darius and Amorges fell from the hill. Going down the hill, Kassandra witnessed Darius making peace with a dying Amorges. The Ancient revealed that Elpidios was on the island that Gergis show to Kassandra. In his dying breath, Amorges warned that the Order will continue to hunt Elpidios and will never be destroyed.
Going to the island, Kassandra and Darius met Elpidios' caretaker, Prince Darius, son of Artaxerxes I. He willingly gave back Elpidios to his family. Understanding that the Order will always hunt her, Kassandra decided to protect her son, leaving him to the care of his grandfather. Before their departure, Kassandra wrapped Natakas' blanket around her son. Darius promised to protect Elpidios while investigating the Ancients. Kassandra witnessed the last remnants of her family take a felucca sailing to Egypt.
Kassandra continued to track the Ancients of the Dominion. As Gergis was dead, Kassandra found a letter from Gaspar indicating she found a strange gate and allied with the Followers of Ares. Founding a letter on a follower's corpse, Kassandra localized Gaspar's hideout and kill her. With a clue left by Darius, Kassandra hunted an Ancient specialized in cleaning up after them. Going to a Persian camp, she found a letter on the Captain's corpse, revealing the identity of the Ancient, Artazostre. Kassandra killed her and found a letter from a Daughter of Artemis indicating that a letter from another Ancient was at their Pedasos Camp. Kassandra stole the letter and discovered the identity of the writer, Pithias, the Dominion planner. Kassandra killed him destroying the Order of Dominion.
Returning at Dyme, Kassandra went to Natakas' grave to tell him what happened. She decided to recover the charm Natakas threw in the sea. She returned in Makedonia, recovering Natakas' Hunting Bow in their old hideout. She also went to the island in Messenia recovering Elpidios' blanket. Going back to the Natakas's grave to place the charm and the blanket while keeping his bow.
Trials of Atlantis
Becoming the Keeper
While exploring the Island of Triton, Kassandra was contacted by a projection of Aletheia, whose consciousness was in the Staff of Hermes Trismegistus. She explained that Kassandra became the Keeper of the Staff and must protect it until she met the Heir of the Memories. Kassandra accepted her new duty. Aletheia tasked Kassandra to find Theras as he knew the location of symbols for the Heir. Arriving in Seriphos, Kassandra saved Theras who was captured by the Cult of Kosmos. He explained to her that Phidias was killed and that the Cult interrogated him about symbols he discovered in three tombs. He gave a map to Kassandra to find them.
Returning to Olympia, Kassandra discovered that Theras told the truth about Phidias. On his brutalized corpse, she found the scytale he tasked her years ago to decipher. With the symbols she found on the statues of Zeus in Olympia, Aphrodite in Kythera, Theagenes in Thasos and Poseidon in Samos, Kassandra could read the scytale. It revealed that there was a secret room in the Stronghold of Lemnos. Going there, Kassandra unlocked the door and recovered the Atlantean Blade, a weapon created by the Isu.
Later, Kassandra went to the tombs of Agamemnon in Argolis, Eteokles in Attika and Orion in Boetia. Each time, she spoke with Alethia who explained her role as Keeper and that she will help the Heir by standing before the tombs. Returning to the Atlantis, Kassandra opened the throne room with her blood and the Staff. Alethia explained to Kassandra that she created simulations for her to learn how to control the Staff through Keeper's Insights. Kassandra accepted to pass the trials, accessing to the first simulation.
Rebellion in Elysium
Unconscious, Kassandra was awaked by a dog. Standing up, she was attacked by Isu soldiers commanded by an Isu woman. After defeating them, Kassandra met Hermes, who recognized her as Pythagoras' descendant as she had his staff. He explained to her that she was in the Fields of Elysium which was ruled by Persephone, Hades' wife. As Kassandra told about the trials, Hermes said that the only way to leave Elysium was through Persephone. He informed her to speak to Hekate, Persephone's advisor. The Isu indicated that Kassandra could prove herself to Persephone if she smothered a rebellion in the Deukalion. At last, Hermes revealed that Kassandra could empower his staff through the Perceptions of Hermes, unlocking new capacities.
Later, Kassandra met Adonis, a living human forced to stay in Elysium as Persephone fell in love with him. Wanting to rejoin his lover Aphrodite, Adonis led the human rebellion against Persephone. Kassandra decided to help him, attacking the Fortress of the Three Sisters. She destroyed the Torches of Hypnos who controlled humans and killed the overseer Aegea. This act convinced Adonis to ally with Kassandra. She also killed the overseers Iphigenia and Atalanta and destroyed other Torches and ressources, decreasing Persephone power in Elysium.
Arriving at Pheraphassa Point, Kassandra met Persephone who apologized to have sent her soldier against her. The Isu informed her that Orphnaeus, one of her husband's horses, disappeared from her stable. Fearing to be accused of stealing the beast, Persephone tasked Kassandra to find the horse. After investigating, Kassandra found that Orphnaeus escaped before being taken care of by the blind man Mulios. After choosing between leaving the horse to Mulios, returning it to the stable, or giving it to Adonis, Kassandra informed Persephone that she solved the problem.
Later, Kassandra met Hekate who proposed to help her to leave Elysium, even if she was Persephone's friend. The Isu gave her the key to Persephone's hidden sanctuary and tasked her to recover Persephone's journal to discover where was the gate to the Underworld. Returning with the journal, Kassandra gave it to Hekate. After reading it, Hekate didn't discover the location of the gate but advised Kassandra to decrease Persephone's power in Elysium to have access to the gate.
Kassandra also met Hermes and followed him on a tour of the Minos' Faith. The Isu explained to her how to unlock the power of his staff through the Keeper's Insights. After founding one in the region, Kassandra found the others in the Elysium, expanding her knowledge and power of the Staff. Later, as Hermes searched for a bodyguard for Persephone, he tasked Kassandra to free Kyros of Zarax from the rebels. When she rescued Kyros, as an old friend of Pythagoras, he revealed to her that he secretly worked for the human rebellion. His captivity served as a cover to be hired by Hermes. Kassandra brought him before the Isu without revealing the truth.
When humans stole Hermes' recipe to the eternal flame, a powerful weapon, the Isu tasked Kassandra to recover it. After killing the thieves, Kassandra retrieved the recipe and chose if she must give the flame to Hermes or Adonis. Later, Kassandra had to choose between helping Hermes kill the leaders of the rebellion or breaking her alliance with the Isu.
As Adonis tasked Kassandra to free humans from Persephone's influence, she learned that Hermes' Staff could liberate their captive minds. After this, Adonis said that an old Spartan warrior could help the rebellion if convinced. Meeting the warrior, Kassandra discovered that it was her grandfather Leonidas. After a fight to see her combat skills, the defeated King accepted to join the rebellion. Later, Kassandra continued to use the Staff to free other humans from their mind-control, who joined the rebellion.
Hekate tasked Kassandra to meet the orator Isidore who could spread the message among humans to join the rebellion. The orator accepted to help the misthios if she rescued captured villagers. She also demanded to her to free her son Theron from his indoctrination. After accomplishing her task, Isidore became an ally of the rebellion. Later, Hekate ordered Kassandra to recover the last Lethe's water for a woman who promised to help the rebellion. After recovering the Lethe, Kassandra met the woman, Almatheia, who wanted to forget about her dead lover. Ultimately, Kassandra had to choose between giving her the Lethe or destroying it. After hearing rumors on Lethe's water entered circulation, Persephone had suspicions of Hekate's loyalty. Kassandra herself had doubts about Hekate's true motives. Kassandra once again worked with Hekate to decrease Persephone's power. During a symposium of Persephone's Devotees, Kassandra poisoned their wine with aconite to kill them.
Adonis discovered that a traitor among the rebellion gave information to Persephone. After identifying two suspects, a blacksmith, and a messenger, Kassandra had to choose which of them she must kill. During an audience with Persephone, the Isu made a deal with Kassandra: bringing from the dead a loved one if she killed Leonidas as he served the rebellion. Kassandra had to choose between killing her grandfather or sacrificing Kyros of Zarax and revealing he was a mole. After the rebellion stole an explosive device from Hermes' workshop, Kassandra brought it in the Palace of the Kolossi, destroying all the Kolossi in the area.
Later, as Kassandra went to Hekate's hovel, Persephone waiting for her. As she didn't trust Hekate, Persephone tasked Kassandra to spy on her during a secret meeting. She discovered that Hekate met Hermes who confronted her about Kassandra's actions. During their conversation, she learned that the key to the gate of the Underworld was the collar of Persephone's dog, Ros. After this, Kassandra must defend her cause before Persephone as Hekate accused her to be the only one responsible for her mischiefs.
With the rebels, Kassandra launched the attack on Persephone's palace. Defeating her army, Kassandra confronted Hermes who was thrown away by Persephone as he failed her. In the throne room, Persephone decided Hekate's fate and how Adonis will leave Elysium. Kassandra tried to convince Persephone to leave Elysium but she refused, throwing an artifact in the pit to the underworld and Ros followed it. Immobilized by Persephone's power, Kassandra was thrown in the Underworld.
Bringing order in the Underworld
Rising from her long fall to the Underworld, Kassandra discovered that the artifact transformed Ros into a giant Cerberos. Forced to fight the monster, she killed the three-headed dog and recovered the artifact. While exploring the Underworld, she met Hades, who was angry that she killed his dog. As nothing kept the dead to return to the living realm, Hades tasked Kassandra to find four heroes to watch the gates of the Underworld. He also informed her to help Charon bring order in the realm as prisoners of Tartaros escaped. As Kassandra wanted information on the Staff, in exchange for her work, Hades promised he will help her fulfill her destiny.
On her way to see the ferryman, Kassandra saw prisoners of Tartaros escaped from a rift. Kassandra killed them by activating the rift which weakened her. Meeting Charon, he informed her that she needed the Armor of the Fallen to pass through the Tartaros Veil to ended the threat of the Shaded. Charon said that The Fallen kept four pieces of the armor while the last one was lost. Through his indication, Kassandra began to collect the armor.
Kassandra went to the Hades' Palace which was attacked by the prisoners of Tartaros. After killing them, Kassandra met Elpenor, the first cultist she assassinated. Now working for Hades, Elpenor proposed to help Kassandra find the gauntlets of the Armor of the Fallen to make amendments to his past life. He explained to her that the Shaded were led by the Monger who resumed the work of the Cult. Going to Kronos' Treasury, Kassandra recovered the gauntlets from the Shades. To claim the four other pieces, Kassandra killed the Fallen who were four past targets: The Poisoner, Epiktetos, Deianeira and Swordfish. With the complete set, Kassandra could enter the Lost Temple of Nyx and killed once again the Monger, sending him to the depth of the Tartaros.
Searching heroes to keep the gates of the underworld, Kassandra defeated Perseus, Herakles, Agamemnon and Achilles, who accepted their new roles. Kassandra also found the Keeper's Insight in this realm, expanding her link with the Staff.
Kassandra also assisted Charon to help lost souls in the underworld. As an Athenian soldier died before he could fight the Spartans, Kassandra dueled him to permit him to enter Elysium. Kassandra tried to cure a woman who died from the plague and didn't receive the proper last rites. During this quest, she crossed the olympian Testikles. Kassandra helped a family who died during the war to find a new home and protected them from the Hounds of Hades. Finally, Kassandra investigated to find a thief who stole the coins of the dead, preventing them to cross the Styx.
Founding a letter from a child searching her parent in the underworld, Kassandra followed the footprints and discovered it was her friend Phoibe, who was amnesic after someone forced her to drink the Lethe's water. To bring back her memories, Kassandra recovered Chara, Phoibe's eagle sculpture. Remembering she died in Athens, the young girl explained that she was in Elysium but went into the underworld to find her parents. Kassandra helped her friend in her quest. Going to the Ixion Wheel, Kassandra saved a woman attacked by guards. The woman explained that they were soldiers of the Cyclops of Kephallonia searching Phoibe and her family. She told them that Phoibe's parents went to Elysium to find her. Phoibe remembered that it was the Cyclops who forced her to drink the Lethe's water.
As Phoibe went to find the Keres to help the woman but didn't return, Kassandra searched her before being ambushed by Cyclops' men. Discovering that Phoibe was captive, Kassandra met Charon who transported her to the Cyclops' location, a recreation of Kephallonia. After killing once again the Cyclops, Kassandra said one last time goodbye to her friend who went to Elysium to reunite with her family.
Among soldiers fighting on the Eternal Battlefield, Kassandra saw Brasidias and helped her friends. After the battle, Kassandra was attacked by Brasidias who, once defeated, remembered they were allies. Wondering why he wasn't in Elysium, Brasidias explained that Hades wanted him to fight his greatest enemy. Believing it was Deimos, Kassandra decided to help his friend, recovering his shield. Going with Brasidias, Kassandra with him his greatest enemy, a doppelganger of himself symbolizing his hubris. After defeating him, they met Hades who explained that Brasidias must confront what defeated him. The Isu led them to the Forest of Oizys to resume their quest.
There, they met the soul of Lilaira. She tasked them to bring her love in exchange for her knowledge. Going to the Cradle of the Underworld, Kassandra recovered a baby's urn containing the ashes of Lilaira's child. Returning to Lilaira, she revealed that her village was attacked by the Spartans led by Brasidias who killed her husband. As she tried to protect him, she was pushed by Brasidias, resulting in a miscarriage. After her losses, Lilaira committed suicide. Discovering the truth, Kassandra must choose if Brasidas was worthy of Elysium.
After all her tasks, Kassandra met Hades to discover what he knew about the Staff. Hades said he never promised that only he will help her fulfill her destiny. Explaining they were five gates in the underworld, Hades wanted Kassandra to guard it. As she refused, the two fought, leading to Hades' defeat. As Kassandra was about to beat the Isu on the ground, Poseidon, Hades' brother, appeared through a portal and conjured a repulsive force between the two fighters. He invited Kassandra to go to Atlantis, a proposal she accepted. As Tartaros rifts began to appear, Kassandra followed Poseidon through the portal while Hades was trapped in a rift.
Dikastes of Atlantis
Looking around her, Kassandra discovered she was in Atlantis, Poseidon's realm where Isu and humans lived together. As he explained that every seven years the city began a new cycle if judged to be imperfect, the Isu chose Kassandra as Dikastes to enforce judgments in the city to prolonge the cycle. He also informed her about the Keeper's sight in the city who could increase her link with the staff but also unlocked the sixth sense of the Isu, knowledge. While learning the duty of a Dikastes, Poseidon told her that experience on humans were forbidden in Atlantis.
The first brother she met was Gadiros who tried to entertain the humans through games to keep them calm. Kassandra participated in the games, fighting soldiers and the Champion of Atlantis in an arena. The games took a gruesome take when Gadiros ordered Kassandra to slaughter unarmed civilians to please the crowd. Later, Kassandra met Ampheres who fought a human rebellion in his district. Kassandra had to decide if she assassinates the human leaders or burns their supplies to stop the rebels. While Azaes tried to cure the humans of a plague, Kassandra recovered an experimental replica of a Shroud of Eden to heal them. They used it on a man who exploded. Kassandra must decide if they continue to use the Shroud or not.
After helping the three Archons, Kassandra returned to Atlas. She discovered that the Archon brought his brothers to execute them for their mistakes in ruling humans. Kassandra tried to convince him to spare them. After the judgment, Kassandra received a key fragment from Atlas.
During her time in Atlantis, Kassandra solved the quarrel between the Isu Neokles and Melitta about the Garden of Triton.When a human Lyra was accused of murder, Kassandra investigated and discovered that Lyra inadvertently transformed into a werewolf. Kassandra also met Elpis, Atlas' human lover. She helped Elpis recover adamant in her project to become an Isu to ease the relationship between Isu and humans.Ultimately, it led to the death of one of the lovers.
Exploring Atlantis, Kassandra recovered her Dikastes armor which was stolen by the Atlantean Polemarchs. Kassandra found the Keeper's Insights in Atlantis and the Isu codex, increasing her knowledge. Finding adamant ingots, Kassandra discovered the Forge of Atlantis and forged different weapons with the metal.
Tired of her duty, Kassandra decided to rest when she was contacted by a young human Alkon who searched his parents. Kassandra investigated, interrogating the Isu Harbormaster and discovering that the Isu Xarios took Alkon's mother for the Project Olympos. In the Atlantis Latomia, Kassandra interrogated the Isu Foreman who told her that Alkon's father was brought to the experiment chamber at the Garden of Kymopoleia. She informed Alkon of her progress before confronting Xarios. After killing him, she found a key fragment.
Combining it with Atlas' key fragment, Kassandra entered the experiment chamber. There, she found in test tubes replicas of the mythical creatures she fought in Greece. While seeing this, Kassandra heard the voice of Aita, the Isu scientist leading the Olympos Project. Investigating the place, Kassandra fought deformed humanoid creatures. Founding Alkon's parents and other imprisoned humans. As Aita broke Poseidon's law on experimenting on humans to create hybrids, Kassandra challenged the Isu who explained that he did it for the betterment of Atlantis. Kassandra threw her spear at Aita but it was only a hologram. The Isu left her the choice between freeing the prisoners or seeing his greatest achievement but at the cost of their lives.
Later, Kassandra confronted Poseidon explaining to him that Isu experimented on humans. Before they could argue longer, Aita arrived with his wife Juno, telling them that they created hybrids in a future war against humanity as Poseidon was more preoccupied with the Great Catastrophe. They said that they thought to use Kassandra as a template for their hybrids but seeing her as too human, they created the Hekatonchires and released it to suppress any future rebellion. While Poseidon restrained Juno and Aita, Kassandra defeated the Hekatonchires, recovering the artifact which transform it.
Even with Juno and Aita imprisoned, Kassandra felt that humanity wasn't safe from Isu in Atlantis. Poseidon agreed with her judgment and explained that she could end Atlantis' cycle forever by using the Staff of Hermes and the prizes of Cerberos and Hekatonchires. By using the Pieces of Eden, water began to flood the city. While the citizens began to leave, Poseidon decided to die with Atlantis as his family failed to fill the gap between Isu and humans. The Isu greeted her farewell to Kassandra, reassuring her that she was the best person to keep the Staff.
Succeeding the trials
Awakening in the throne room, Kassandra spoke with Aletheia who congratulated her for passing the trials. She explained that they were based on Isu's memories, even some of her own when she was Dikastes. As holograms of Leonidas, Brasidias and Phoibe appeared, the Isu explained that the trials taught Kassandra to say goodbye to her friends. When Kassandra asked if they were real in the simulations, Aletheia only said they were always with her.
When holograms of the Persephone, Hades and Poseidon appeared, Aletheia explained each teaching of the trials: Elysium was doomed as its ruler searched for total control, the underworld was devasted by chaos, and Atlantis show her the flawed nature of the Isu. With that, Aletheia affirmed that Kassandra's role was to keep the powers of the Staff, not to rule the world. Swearing to protect humanity as the Keeper, Kassandra left the Gateway of Atlantis.
Vacation and adventure in Korfu
However, exhausted and pressured by her new responsibility, Kassandra decided to take a break from her duties, travelling to Korfu to rest and relax. However, this did not last long as she was soon found by Barnabas and Herodotos who followed in her leads. After much persuation, she was convinced to participate in a treasure hunt planned by Barnabas himself.
This hunt was soon further complicated with the involvement of an Apple of Eden which permanently disable the power of Kassandra's spear after interacting with it. The interaction also caused launched the Apple to fly northwards, where it came under the posession of Barnabas. Barnabas, under the influence of the Apple, created a path of destruction which left civilians and villages destroyed. However, Kassandra was able to confront Barnabas in the Temple of Zeus in Kassiope and free him from the Apple's control.
These events led Kassandra to ultimately embrace her role as the Staff's Keeper and to prevent people around her from interacting with the Isu artifacts. After handing over her depowered spear to Herodotos, while receiving of the historian's manuscripts, Kassandra departed from Greece with onaboard the Adrestia with Barnabas choosing to remain by her side until the end.
Search for Isu artifacts
After departing from Greece, Kassandra travelled to her first destination of Egypt, arriving in the city of Alexandria. There, Kassandra came upon the Great Library where she chosed to place Herodotos' manuscript, preserving his stories amongst the city's residents.
Over the years, Kassandra devoted herself to tracking down Isu artifacts throughout the world similar to the ones she found in Greece. In each area she visited, she would not remain for long in order to prevent herself from attracting attention. By the 9th century CE, her search brought her to Northern Europe, where she became acquainted with the Hidden Ones operating in the region, occassionally working alongside them with their shared goals. Kassandra was even given a Hidden Blade for her relation with the Hidden Ones.
In the 880s, Kassandra learned of a Piece of Eden on the Isle of Skye in the Kingdom of the Isles which has been disrupting the local population and driving them mad. During her investigation, she encountered and befriended the Viking Eivor Varinsdottir of the Raven Clan, who was investigating the strange phenomenon on behalf of a woman named Edyt.
Later life and death
Having faded into obscurity over the centuries, her identity was rediscovered through a book by Herodotos called Lost Histories, found by the former Abstergo Industries employee and later Assassin Layla Hassan. In 2018, this helped Layla relive Kassandra's memories through the Animus and find the Staff of Hermes Trismegistus. When Layla ventured into the Gateway to the Lost City, Kassandra finally appeared before her and bestowed her with the Staff, in the process passing away.
Personality and traits
- "I always finish what I've started."
- ―A catchphrase of Kassandra as a misthios.[src]
Kassandra had a soft spot for children, particularly Phoibe, a young orphaned Athenian girl. She also possessed a scar on her right upper lip and heavy scarring down her arm from falling from Mount Taygetos as a child. According to both Phoibe and herself, she was rather immune to illness.
Skills and equipment
Trained from a young age to fight as a Spartan, Kassandra was a highly skilled warrior capable of defeating multiple opponents simultaneously. Kassandra was able to competently wield a variety of weapon types, including swords, bows, spears, and axes. Unlike most Spartan warriors, however, Kassandra did not rely on a shield for protection, instead being able to easily deflect enemy attacks.
A master of stealth, Kassandra was able to silently assassinate her targets undetected and was also able to utilize the foliage of bushes to remain hidden from her enemies. She also proved proficient in the use of the Spear of Leonidas which aided her in silent assassinations. The Spear also gifts Kassandra with Superhuman powers which includes enabling her to know what, when and how her enemies are going to attack, giving her a major edge over her enemies in combat. It greatly enhances her physical strength to the point where she can send normal and giant-sized men to animals as large as grizzly bears flying through the air dozens of feet away from her in a single blow with sufficient force. Her blows could even stagger Legendary beasts like the Nemean Lion and a Cyclops with significant effort.
She could also briefly enhance her speed and reflexes to the point where she can move faster then a human eye can see or react to and can also regenerate her injuries that would normally be fatal. If necessary, the Spear can also turn her invisible for a short while, allow minor control over poison and fire, produce concussive shockwaves, charge arrows with raw explosive energy, phase arrows through solid objects, and very minor control over time, only allowing for time to be stopped for five seconds.
A skilled freerunner, Kassandra was able to scale the statue of Athena in Athens as well as natural elements with relative ease. She also proved to be a strong swimmer whilst searching the ruins of underwater shipwrecks and was capable of holding her breath for a relatively long period of time.
Kassandra shared a symbiotic relationship with her eagle, Ikaros, which aided her in reconnaissance thanks to her Eagle Vision. Unlike later generations who possessed the skill, her Eagle Vision was far more literal in the sense that activating the ability allowed her to see through the eyes of Ikaros. Like the Daughters of Artemis, Kassandra could also tame a variety of wild animals to fight with her.
With the Staff of Hermes Trismegistus, which was passed on to her by her father Pythagoras, Kassandra was rendered immortal and remained unchanged for far longer than two thousand years. With the staff, she no longer required food or water as the staff sustained her needs. She could even cause the Staff of Hermes to transform into anything she chooses, such as a lantern. While never shown, it is assumed she could use everything the staff gave to its user, including short range teleportation and energy manipulation and projection. However shortly after coming into possession of the Staff, Kassandra learned the Staff can easily corrupt individuals who lack the strength to control it, setting Kassandra through simulations of Elysium and Hades to gain control of the staff as well as full tap into her own hidden potential. During her journey through Elysium, Kassandra learned to tap deeper into the spear's power, able to enhance several of her abilities to the level of an Isu as well as briefly summon the Full Power of the Spear of Leonidas. With these abilities Kassandra grew to rival the gods themselves, easily besting Hermes, an actual god and slaying the mighty Cerberus. After her trials through Atlantis and under the guidance of Poseidon and fully awakening the Isu's sixth sense of Knowledge within her does Kassandra come to control the staff and realize that is actually is far more destructive then it appears, having the power to destroy entire cities if she wanted to, which she displays by destroying Atlantis after learning how horribly the Isu treat humans.
By 2018, Kassandra had a great deal of knowledge of every innovation and discovery which have happened in her immensely long lifespan, recognizing Layla's device. She also is aware of a great deal of historical information as well as the existence of many secret societies that have risen during her immensely long lifespan.
Behind the scenes
Kassandra is one of two selectable protagonists in Assassin's Creed: Odyssey, alongside Alexios. Regardless of who the player chooses, the two protagonists share the same story. However, the novelization of the video game confirms that Kassandra is the canonical protagonist. She is voiced by Melissanthi Mahut who also provides the motion-capture. Maria Syrgiannis voices her as a child with Jennifer Michele providing motion capture.
If the player chooses Alexios as the protagonist then he and Kassandra's roles in the story are reversed, with Kassandra becoming Alexios' younger sister. The game writers original intent was for Kassandra to be the sole protagonist of the game but Ubisoft executives told them that wasn't an option. As of January 2019, one-third of Odyssey players have chosen Kassandra as the protagonist. During playtesting, the split was 50/50.
Kassandra (Κασσανδρα) is an Ancient Greek name derived from possibly κέκασμαι (kekasmai) "to excel, to shine" and ἀνήρ (anḗr) "man", altogether meaning "shining upon men". Her name could also be a reference to the Trojan princess who was given the power of foresight by Apollo, but when she rejected him, he cursed these visions so that they would come true, but she wouldn't be believed (this is known as the "Cassandra metaphor", in which a figure with knowledge of the truth and/or upcoming disasters is ignored).
