"The Staff is a gift, not a toy! It can be a key, a weapon, and a way to attain power until the very end of time."
―Hermes Trismegistus[src]

The Staff of Hermes Trismegistus, also known as the Staff of Hermes or the Caduceus, is an extremely powerful Piece of Eden created by the Isu philosopher Hermes Trismegistus.

From its creation until the 6th century BCE, it was wielded by Hermes himself before he passed it on to Pythagoras who, in turn, passed it on to his daughter, Kassandra a century later. Becoming its Keeper for more than two millennia, Kassandra passed the Staff to the Assassin Layla Hassan in 2018. In 2020, the Staff was acquired by the Hidden One Basim Ibn Ishaq after Layla dropped it in the Isu Temple holding Yggdrasil.



Isu Era

During the Isu Era, the Isu Aletheia replicated her own consciousness into the Staff in order to save her life from a fatal wound. Resolving to meet her lover Loki in the distant future when he eventually reincarnated,[5] she waited in the Staff until such time came that she could interact and help the staff wielder to master its power[3] and unwittingly serve her own purpose.[5]

6th century BCE

Around the 6th century BCE, Hermes met the Greek philosopher Pythagoras along with his protégé Kyros of Zarax in a remote desert. Declaring the former a worthy successor, Hermes handed over the Staff to Pythagoras before disappearing. Pythagoras later parted ways with Kyros,[2] embarking on a journey to learn about the Staff.[3]

5th century BCE

Living abnormally long using the Staff, Pythagoras fathered a child with Myrrine of Sparta and eventually discovered the sealed ruins of Atlantis, with which the Staff was connected. There, he spent years attempting to uncover the secrets of the place, only to find its entrance sealed by four artifacts.[3]

During the time of the Peloponnesian War, the Spartan misthios Kassandra, Pythagoras and Myrrine's child, reached the entrance to Atlantis and encountered Pythagoras, still alive thanks to the Staff's power. Following the encounter, Pythagoras tasked Kassandra with finding the four artifacts that, combined with the Staff, would allow the pair to either permanently seal off Atlantis or open its gates to acquire the knowledge contained within.[3]

After Kassandra recovered all the artifacts, Pythagoras briefly considered opening Atlantis, but after a brief argument with his daughter, he relented to sealing Atlantis and entrusted the Staff to her. No longer artificially sustained by the Staff's power, he then passed away.[3]

Sometime later, Kassandra began to hear the voice of Aletheia coming from the Staff and eventually witnessed an apparition-like hologram. Aletheia explained to Kassandra that her role as the Keeper of the Staff was to hold onto it until she met the "Heir of Memories". Kassandra visited four different tombs under the directions of Aletheia and slowly began to understand that the Heir of Memories Aletheia spoke of did not yet exist.[3]

Under the last direction from Aletheia, Kassandra descended back into Atlantis and used her Hybrid Isu-Human blood to gain entrance to the outermost part of Atlantis, the Throne Room, where Aletheia presented Kassandra with three fictionalized simulations of the Sister Realms; Elysium, the Underworld and the last days of Atlantis; wherein Kassandra would learn to use the power of the Staff. After enduring these trials, Kassandra fully embraced her role as the Keeper and fully obtained the power of the Staff.[3]

21st century CE

In 2018, Layla Hassan and her cell of Assassins managed to find the entrance to Atlantis using the genetic memories of Kassandra that were recovered from the Spear of Leonidas. While in Atlantis, she met with Kassandra, who had used the Staff's power to survive until that time. Believing Layla to be the Heir of Memories that Aletheia had mentioned, Kassandra passed the Staff on to Layla and instructed her to destroy it and all other Pieces of Eden with it before passing away herself.[3]

Following Kassandra's death and her experience with her memories, Layla began communicating with the virtual consciousness of Aletheia and visited the four tombs that Kassandra had visited before her time as Keeper in order to find the right passcode to enter the Atlantis Throne Room proper.[3]

Once inside, Layla once again relived the genetic memories of Kassandra, this time of her time within the simulations. While within the the throne room, Victoria Bibeau accompanied her and attempted to stop her from continuing, noting her instability and fearing the Staff and her brief sojourn into the genetic memories of Deimos had caused a sort of corrupting Bleeding Effect.[3]

Soon, the duo was ambushed by members of Sigma Team, elite Templar operatives under the command of the Juhani Otso Berg. Layla used the Staff to defend and kill most of the ambushing party, leaving only one alive to allow him to return to his leader. Noting Layla's brutality, Victoria tried to actively stop her from continuing the simulations, causing Layla to strike her with the Staff in a fit of rage. Immediately contrite, Layla attempted to ensure Victoria's safety but soon returned to the simulation.[3]

With Aletheia doubtful of Layla's role as Keeper of Memories after this violent episode, Layla discovered that she had, in fact, murdered Victoria. Still, Layla continued into the simulations despite Aletheia's doubts. After finishing the last simulation, Layla awoke to discover that Otso Berg himself had come to Atlantis' throne room to confront her and take both Atlantis and the Staff. Using the Staff as a spear, Layla defeated Otso in combat. Soon afterwards, she stabbed Otso, leaving him paralyzed but stable and gloated over her newfound immortality. Taking the earpiece from Victoria's corpse, Layla called for an extraction.[3]

While exploring the memories of Eivor Varinsdottir to attempt to figure out a way to normalize the planet's magnectic field, Layla would keep the Staff inside a case so as to not be affected by it. After going to the Isu temple of Yggdrasil, she used the Staff to connect to the device, dropping it and unknowingly releasing Basim Ibn Ishaq. Basim then took the Staff and healed himself with it. [4]


"I'm not worried. I have the Staff of Eden. It heals and protects."
―Layla Hassan, 2020.[src]-[m]

The Staff of Hermes' most prominent ability is to bestow its wielder with biological immortality. It has the power to preserve its owner and protect them from the passage of time as well as to sustain them. Pythagoras was able to stay alive for centuries inside Atlantis with only the Staff, without requiring sustenance.[3] The Staff also possesses instantaneous regenerative functions which are similar to the regenerative abilities possessed by the Shrouds of Eden. This was evident at how the Staff was able to revive and fully regenerate Basim's biology back to his prime.[4]

However, once he finally passed down the Staff of Hermes to one of his children, Kassandra, he almost instantly passed away. The Staff was able to keep Kassandra from aging for far longer, for more than two thousand years, until she was able to pass it down to Layla. Like Pythagoras before her, she passed away after handing over the Staff, with her body even rapidly aging, demonstrating the limits to the immortality granted by the Staff—it did not truly prevent aging. Whether physical contact between the wielder and the Staff is required to impart such longevity is unknown. Those who passed ownership of the Staff onto another individual, either willingly or by force, at a point that was past the former owners natural lifespan would die almost instantly. This passage of ownership required both parties to maintain simultaneous physical contact on the Staff.[3]

Aside from its life-giving powers, the Staff of Hermes was the key to sealing off Atlantis and could take the form of whatever its user wished, given that Kassandra came back to Atlantis to greet Layla with the Staff in the shape of a lantern. In a potential though untrue simulation of Kassandra's memories, Kassandra fights Pythagoras over the sealing of Atlantis, where the Staff gives Pythagoras the physical attributes of a young man despite his elderly appearance. In this false simulation, he is able to use the Staff to create precise blasts of energy and teleport short distances during combat. He is also able to conjure balls of energy, channel the Staff's power into himself, and project that energy from his hands.[3]

The Staff can easily corrupt those who do not possess the strength to wield it. Aletheia therefore created simulations for Kassandra to learn how to control it and through her, the Heir of Memories. The simulations allowed Kassandra to learn and fully control the staff, but while Layla was experiencing these same memories, it became clear to Aletheia that she was becoming corrupted by the staff. She began to doubt Layla's role as Heir of Memories after her violent fit which resulted in the death of Victoria.

Behind the Scenes

The Staff of Hermes Trismegistus first appears in Assassin's Creed: Project Legacy as Hermes Trismegistus' gift to Pythagoras in Chapter 2 of the Divine Science pack of memories. In these, the staff is described as adorned with living snakes, capable of speech, and presenting intelligence so that the staff chooses Pythagoras as the successor of Hermes Trismigestus. Similarly, it's implied in these that the Staff passed hands multiple times before Hermes Trismegistus bestowed it to Pythagoras.

The Staff reappears in Assassin's Creed: Odyssey as an important item in the Atlantis quest lines and The Fate of Atlantis DLC episodes. Furthermore, the Staff is acquired as a weapon after the memory "Ancient Revelations". Despite its name, it is registered as a spear and shares the same animations as all other spear weapons, differing only in stats and Engravings.
