During her mercenary travels, 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 was born in Sparta 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 his 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 her own flesh and blood, raised her as one of his own. Kassandra would later gain a younger brother named 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 as a child, Kassandra was presented with the broken Spear of Leonidas, an Isu weapon, as an heirloom by her mother. Afterwards, Kassandra wouldn't let go of the spear, even in her sleep, telling her parents that she needed it "to fight the monsters in [her] dreams."
Exile From Sparta
In 446 BCE, 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 greeted by Markos, who took her under his wing and tasked her to do errands for him.
Life as a misthios
As the years went by, Kassandra continued performing errands for Markos, occasionally helping him to settle debts that he owed. Around this time, she 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. At some point, she and Markos took an Athenian orphan Phoibe as part of their 'family'.
Kassandra set up home within the Ancient Ruins of Kranioi on the western coast of Kephallonia, far from other people. She worked from there, and 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 vineyard, 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 was 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. Assured that Phoibe was alright, Kassandra then traveled to Sami to locate Duris and collect her debt. In doing so, she was given the revealtion that Markos had bought his vineyard with money he borrowed from the Cyclops. Once Duris has been dealt with, Kassandra returned to Markos at the Temple of Zeus, catching him speaking to one of Cyclops' thugs. As they 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.
Odyssey through Greece
Working for Elpenor
Afterwards 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. Kassandra then went to an abandoned house the bandits were squatting 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. Subsequently, after Kassandra recovered the item, Elpenor 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 made the acquaintance of 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, Kassandra met Stentor, the adoptive son of Nikolaos. As she asked to met the general, Stentor hired her as a mercenary to fight the Athenians in the region due to the Peloponnesian War. After defeating the Athenian army, Kassandra became know as the midsthios with the broken spear. She confronted Nikolaos alone but decided to spare his life. Regreting 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.
Arriving in Kirrha, Kassandra met Elpenor and showed him Nikolaos helmet to prove she accomplished her mission. As the discussion went wrong, Elpenor flew while his guards attacked Kassandra. As she survived, she decided to track down Elpenor in the region.
Uncovering the Cult of Kosmos
Going to the Sanctuary of Delphi to question the Pythia about her family, Kassandra met 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. Talking alone with the Pythia Kassandra discovered that the Cult had a meeting under the Sanctuary and that Elpenor was a member of the Cult. Finding his hideout she fought him and kill him. On his corpse, she found a mask, a robe and a strange shard.
With the mask and the robe, Kassandra went to the reunion of the Cult in the Sanctuary of Kosmos. In the middle of the room was a Pyramid composed by the same type of shards she found on Elpenor and decided to complete it. During the meeting, Kassandra learnt that the Cult had infiltrated the different levels of Greek society: economy, religion, politic. They even had men in Delian League and in the Peloponnesian League. She also discovered that the Cult wanted her family dead to end the bloodline. Deimos, who was the weapon of the Cult, entered in the room throwing Elpenor's head. To find the traitor, he test the members with the Pyramid. When it was Kassandra's turn, the two saw memories of their childhood. Kassandra understood that Deimos was Alexios. Pertubated, Deimos decided to let Kassandra went and accused Epiktetos to be the traitor before killing him. During the confusion, Kassandra took two shards of the Pyramid before leaving the hideout.
After that, Herodotos convinced Kassandra to join him in a travel to Athens for reporting to Perikles the informations she gathered. Before sailing to Athens, Kassandra met Herodotos at the Lion of Leonidas at Thermopylai, where her grand-father 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 a old complex on the Andros island. Kassandra went on the island and opened the Isu construction with her spear. In there, she found a mold corresponding to the spear and using shards she took from the Pyramid, she upgraded the weapon. Leaving the Ancient Forge, she was confronted by her brother, who accused her to have throw him when he was a child. Kassandra tried to tell him the truth but his endoctrination by the Cult was to strong and left her sister alone. Kassandra returned on the Adrestia to tell to Herodotos what she saw and they began their trip to Athens.
Interfering in Athens politics
In May 431 BCE, Kassandra and Herodotos arrived in Athens, which was besiege by the Spartans. The population was tired by the Perikles' strategy to wait behind the walls of the city until the enemies left. The politician Kleon was for a most aggresive tactic and the population was ready to follow him. As Kassandra wanted information about her mother, Herodotus told her she could go to the Perikles' symposium but the Athenian leader said she must help his friends to be accepted by the Athenians.
The sculptor Phidias was targeted by the Cult of Kosmos. 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 snakes. Kassandra discovered that the thugs were poor peoples manipulted by a mercenary to kill Metiochos. She found the mercenary and killed him. Later, Kassandra helped to rig the ostracization of Anaxagoras to be sure he will be exiled. After the vote, Kassandra met the philosopher Sokrates who questionned her about her choices.
After accomplishing her missions, Kassandra was accepted to participate to Perikles' symposium. Entering in Perikles' Residence, she met Phoibe, who left Kephallonia to search her parents, working now for Aspasia, Perikles' lover. Entering in the party, Kassandra spoke with Herodotos who introduced her to the guests of the symposium: the playwriters Sophokles, Euripides and Hermippos, the sophists Protagoras and Thrasymachos, Sokrates and Perikles' nephew Alkibiades. Speaking to Sophokles, Kassandra learnt that Euripides heard about a Spartan woman. After drunken him with wine, she discovered that the woman went to Asklepios Temple in Argolis to save her son. He told to Kassandra to speak to Hippokrates in Argos to have more informations. After giving some oil to Alkibiades, the young man adviced Kassandra if she searched a woman who took her independence to go to Korinth and spoke with the influencial hetaera Anthousa.
Discussing with other guest, Kassandra met Aspasia. Learning about her mother, the hetaera told to Kassandra to met her friend Xenia on the island of Keos for having more information. After that, Kassandra spoke to Perikles about the Cult of Kosmos and the threat they represented for Athens. Later during the night, Kassandra left the party after saying goodbye to Phoibe.
Before searching her mother, Kassandra helped the playwriter Aristophanes to investigate on 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. She killed him after he tasked to kill a woman against the freedom of one of his slaves. She also helped the general Demosthenes and Kleon to fight the Spartans who camped around Athens. She was tasked by Kleon to join two of his men Heremos and Onomakles. The first one was dead but she saved the second before destroying the Spartan fleet permitting to Onomakles to go to Mytilene.
Searching 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. As he need his notes to heal his patients, she went to Fort Tiryns but the notes was burnt. She escorted the doctor of the fort to Hippokrates as he red 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 his wounded son. Going in the Temple, Kassandra helped the priests. They all gave information on the priest Mydon who had his tongue cut. Going to interrogate Mydon, Kassandra surprised with his lover who was his 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 decided to cut Mydon tongue to impeach him to speak about it. Kassandra understood that Chrysis made believe her mother that Alexios was dead to abduct him.
Going to the Altar of Apollo Maleatas, she was attacked by Cultists, understanding 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 to become the weapon of the Cult. She also explained that her mother fled to Korinth after that and that The Monger was sent to capture her. Chrysis proposed Kassandra to join her family but she refused. The Cultist set in fire the altar with the baby in here to run away from Kassandra. While Chrysis fled, she was killed by her son Dolops.
Arriving in Korinth, Kassandra entered in 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 hetaerai 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 was agreed that Kassandra killed the Monger but steathly. 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 gave a shelter to her mother and that she fled Korinth with 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 stroke by the plague. As Hippokrates tried to save the sicks, she helped him to burn the bodies of the deads as the Followers of Ares impeached that, seeing this practice as sacrilegious. Going to see Perikles, she learnt from Aspasia that he was sicked. Speaking with the strategos, she understood he was really weaked and that Kleon will 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 deposed Chara on the corpse of her owner. 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 Piraeus. Before leaving, she asked to Sokrates and Hippokrates will stay to bury Phoibe. 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 the Adrestia sailed in this direction.
Finding her parents
Arriving in Naxos, Kassandra learnt that her mother became the Archon of the island. When she met her, the touching reunion between the daughter and the mother was stopped as Naxos was attacked by Athenians from Paros Island. Kassandra and Myrrine went to the battle and killed the invaders. 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 together the Cult and saved Alexios from its control. As Naxos and Paros was in war, Kassandra helped her mother to defend the island and weak the power of Silanos, Paros' Archon. 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 restisted to 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 vicory 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 daughter and the mother 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 her that she was in the ruins of the legendary Atlantis which contained powerfull knowlegde. 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 ok 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 adviced her to deal with the Helots revolt in Sparta to be sure that the rulers will listen 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 will 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 accidently made the champion fell in the sea and been eaten by a shark. Alkibiades who was there proposed that Kassandra remplaced Testikles for the Panchrates. Arriving in the Sanctuary of Olympia, Kassandra participated to the rituals of Olympic Games with Barnabas. During the competition, Kassandra defeated Orion and Erastos which qualificated her for the final. While she celebrated her first victories, Alkibiades collasped after he returned from a party. As Barnabas supposed he was poisoned, Kassandra investigated the case. She discorvered the corpses of other Athenian guests and was attacked by a guard of the Cult. Interrogating the merchant Priam she learnt that someoene 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. Receving an olive wreath, Kassandra was confirmed as an Olympic champion. In Olympia, she discovered that the champion Kallias was the Cultist who poisoned Alkibiades. She killed him an collected more informations 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 which 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 Kyrenia, Samos and Thasos. Kassandra agreed to accomplish this quest.
In Arkadia, Kassandra was attacked by the misthios Sosipatros as a bounty was on her head. After she defeated him, she learnt that this was the Spartan Archon of Arkadia Lagos who ordered her death. 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 forced Lagos to do that. When they confronted Lagos, Myrrine killed him.
In 427 BCE, 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 killed the champion. Discuting with him, he explained her that he helped Stentor in the shadows to repair the wrong he did to his family. Kassandra convinced him to reuniting with Stentor. As she accomplished her mission, Kassandra joined the Spartan troops and defeated the Athenians on the battle ground. After their victory, Stentor duelled Kassandra for avenging Nikolaos' death but as the Wolf of Sparta appeared to seperate 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.
To have more information on the Sage, Kassandra killed Skylax the Spartan leader of the Abantis Islands. With all the members of the branch dead, Kassandra completed the Spartan War Hero Armor and determined that Pausanias was the Sage. Returning in 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. In Pausanias affairs, in addition to taking the Xiphos of Dionysos, Kassandra found a letter from the Ghost of Kosmos, the leader of the Cult, who said it will trick the misthios to believe that Archidamos was the Sage of the Peloponnesian League and asking to Pausanias to uniting the Greek cities under its command.
Fighting the Sage of the Delian League
When Kassandra and her mother entered in her 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 as their sides. She accepted and went in Messenia. In Summer 425 BCE, the two army battled. During the fight Brasidas was wounded by Deimos who then attacked Kassandra. The duel was settled between the siblings as a burning tree fall on them, making them unconscious.
Waking up, Kassandra saw she was in the Athens prison 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 in the prison to save her. They gave her equipement and together went to Perikles' Residence. They formed with Aristophanes, Alkibiades, Herodotos and Hippokrates the Periklean Circle, a group dedicated to dimish the power of Kleon and brought 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 a 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. Kassandra took Paris' Bow and found a letter from the Ghost which proved that the leader of the Cult organized the death of Perikles and asked to Kleon to unite the Greek cities under its control. Returning on the battlefield Kassandra didn't found the body of Alexios.
Reuniting her family
Returning in Sparta, Kassandra told to her mother what happened in Amphipolis and the undetermided fate of Alexios. Going to Mount Taygetos to turn the page, they saw Alexios near the cliff. They tried to resonate him to leave the Cult and join his family, but he lost the will of living. In a desesperate move, he threated his mother with a blade, forcing Kassandra to kill him. She recoverd his sword and his armor. She also found a letter from the Ghost of Kosmos which prove that the leader of the Cult manipulated every members against each others.
After the tragedy of losing her brother, Kassandra tried reformed her family. She organized a dinner in her old house with her mother, Nikolaos and Stentor. They decided to follow her through Greece on the Adrestia becoming her lieutenants.
Kassandra also returned to Perikles' residence to celebrate with the Periklean Circle their victory over Kleon and the Cult, rememoring Kassandra's aventures and paying respect to their friend fall during the War. The Athenian general and politician Nicias, who was a member of the Circle, engaged with Sparta the proposal of a peace.
During her journey, Kassandra also searched the fragment of Atlantis. Pythagoras gave her the half of a medallion of the Isu and adviced her to go to Boeotia to meet his ally Gorgias. Arriving in the Lair of the Sphinx, he informed her that his apprentice Pibos had the other half of the medallion but he disappeared. Searching him, Kassandra found him dead, devoured by a lion. Understanding that the lion ate the medallion's other half, she hunted it and killed it.

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 was a medallion of the Isu.
Reuniting with Empedokles on the Isle of Thisvi, Kassandra opened an Isu gate. In the cave was the Cyclops Brontes, who killed Empedokles. Kassandra fought the giant and killed him. Like for the Shinx, when she took the eye of the creature it turned back as the Prize of the Cyclops and took the Polyphemos Cyclops Bludgeon During other travels, Kassandra fought two other Cyclopes, Steropes on Andros island and Arges in the volcanic island of Nisyros. She defeated them each times.

Interrogating the Collector, she learnt that Nikios, the Swordfish and tried to kill the Minotaur using the Theseus' armor. As they were afraid of the creatures they flew but left behind Nikios. He gave a part of the armor to protect Kassandra and explained where was the other parts.

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 which was the Prize of the Medusa and took the Harpe of Perseus. She paid respect to the petrified Bryce before leaving the Temple. After that, Kassandra met a woman who pretended to create an exilir who reversed the effect of the petrifaction but 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 to Pythagoras to pass the Staff. In her last message, Aletheia spoke with someone who wasn't there.
After that, Kassandra asked to Pythagoras how they will sealed the Atlantis. He said that the Staff of Hermes Trimegistus 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 discovered 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 promised to Herodotos and Barnabas to never talk about the Atlantis to anyone.

She killed Sotera in Megaris and Midas in Argos from the Eyes of Kosmos to locate their Sage, Nyx the Shadow. In Athens, Kassandra assassinated her. On her body, she found proof that the Ghost influenced Athenian politics. With all the Cultist of this branch dead, Kassandra recovered the Snake Set and the Dagger of Kronus.

She learnt that their Sage Polemon hid in the Teichos of Herakles in Achaia. She infiltrated the fortress and killed him. In his affairs she found a letter of the Ghost which explained that it wanted to create a new era. With all the Branch dead, Kassandra collected the armor of Agamemnon and the Elysian Axe.
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 led 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. Whatever, she killed him, liberating the islands. On Chios, Kassandra was hired by the merchant Thais to kill Kodros, the leader of the Petrified Islands, who was corrupted. She found out he was a Cultist and killed him. Arriving on Lemnos, Kassandra was contact 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 poisonned 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 recovered the Athenian War Hero Set.
On the Adrestia, Kassandra explored the seas to killed 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 tthe leader's son, Melanthos, was a Cultist. She located him and sank his ship the Kronos. With all the fleet destroyed, Kassandra completed the Pirate Set and located their Sage The Hydra near the coasts of Messenia. She attacked his ship the Hyperion. When she killed him, she found the Gorgoneion Xiphos and discovered that the Ghost was a woman.
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 contact 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 pretended she can fought the Minotaur and gained many drachmae. After three pre-trials which were tourist trap, Kassandra could enter in the Cave of the Brave. She discovered that Leiandros disguided himself as the creature to attire 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 its was the plan of Melite, a Cultist. Kassandra killed him in Kydonia. Kassandra assembled the Immortal Set and located the Sage Iokaste on Chios. She infiltrated the Anavatos Ruin and killed her. She recovered the Rod of Asklepios and discovered that Ghost used the 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 duelled and killed Belos the Beast of Sparta. During the conquest of Achaia, Kassandra fought Pallas on the battlefield and killed him. She recovered the Amazon Set and discovered that their Sage was Exekias the Legend, the best misthios in Greece. Kassandra tracked him and killed him obtaining the Typhon's Mace. In a letter, she learnt that the Ghost desired to be free. With all the fragments of the Cultists, Kassandra upgraded the Spear of Leonidas to its maximum.
With all this 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 beween 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 was a hero. But in counterpart, without Chaos, another group will imposed 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 the 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 to Kassandra to join her. She refused but let Aspasia left the Sanctuary alive and received her circlet. 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 in hostage the villagers. Kassandra killed the soldiers, saving Aiantides and the other habitants. As she seeked for other hostage, 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 this men knew her and obeyed for the Huntsman. While Natakas decided to rest 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 who seeked to impose order in humanity by force. He told to Kassandra that Natakas and him flew the Order since the dead 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 Magi of the Order of Hunters, a branch of the Ancients. They decided to tracked them. 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 to found medecine on ships took by pirates. Kassandra aboarded them but found that they were Persians. As Natakas informed her that the village was poisonned, Kassandra understood that Timosa was the one who did that as the was a Hunter. After a fight, she killed her.
Personality and traits
As a mercenary, Kassandra had one prime goal - drachmae. Willing to go to extreme lengths to earn it, Kassandra had no qualms about choosing sides in battle. She had a soft spot for children however, particularly Phoibe, a young orphaned Athenian girl. She was able to hold a grudge, as seen with how she reacted when she was reunited with Nikolaos, her estranged step-father. Kassandra was also known to be impatient and quick to anger at times, and would often intimidate those who angered her.
Equipment and skills
- "To shoot, you need to raise your elbow to be level with your ear, keeping your arm straight and relaxed. Your arrow needs to be just below your eye, then exhale on release. Try to aim for the eye so that you don't damage the rest of the meat."
- ―Kassandra, on the bases of archery[src]
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, although the Spear does have a limit, as shown during the flashback of Leonidas' death that Kassandra experiences upon visiting his grave. 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. 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 a 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.
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.
With the Staff of Hermes, 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 it's 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 though simulations of Elysium and Hades to gain control of the staff as well as full tap into her own hidden potential. After her trials through Atlantis and under the guidance of Poseiden 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 discoveries 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.
- Kassandra (Κασσανδρα) is an Ancient Greek name derived from possibly κεκασμαι (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).
- 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.
- 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.
- Kassandra has a scar on her right upper lip.
- As of January 2019, one-third of Odyssey players have chosen Kassandra as the protagonist. During playtesting, the split was 50/50.
