"Call me Aletheia. I am truth and its revelation, and I am calling you out."

Aletheia was an Isu and the Dikastes of Atlantis around the time of the Human-Isu War. Unlike many of the known Isu who were deified by their human slave species, Aletheia became a personification of truth and was repulsed by those among her own people who had embraced divine status.[1]

Before her death, Aletheia replicated her own consciousness into the Staff of Hermes Trismegistus so that she could one day interact with the Keeper of the staff and help the Staff's heir in her journey.[2] She also made numerous recordings on the Olympos Project and stored them in the Gateway to the Lost City, a vault connected to Atlantis. In order to teach Kassandra how to use the staff, Aletheia also created several simulations based on the memories of her time as Dikastes of Atlantis.


Dikastes of Atlantis

"In my time as Dikastes, I also tried to bring balance to Atlantis, but it wasn't enough."
―Aletheia to Kassandra, c. 422 BCE.[src]-[m]

During the Isu Era, Aletheia served, for a time, as the Dikastes of Atlantis, appointed by the city's ruler Poseidon. During her tenure, she attempted to bring balance by passing judgement on the city's laws and customs.[3] At one point, Aletheia became aware of the Olympos Project,[4] a scientific exercise conducted by her fellow Isu Aita and Juno as a means to quell a rebellion by the humans if they ever revolted.[3] Horrified at their experiments, Aletheia made numerous recordings detailing their actions and stored them in a number of steles in a vault connected to Atlantis.[4]

In time, she also became acquainted with Hermes Trismegistus and replicated her own consciousness into Hermes' own Staff, so that she could one interact with and help the wielder of the staff, known as the Keeper, to control its power in the future beyond her time.[2]

Helping the Keeper

Sometime after 422 BCE, on Poseidon's Island, a projection of Aletheia appeared before Kassandra, now the owner of the Staff of Hermes Trismegistus. She told Kassandra to pledge herself to the "Heir of Memories". She then told Kassandra to find Theras, in order for the Heir to continue her journey.[2]

Aiding the Heir of Memories

After finding Theras, Kassandra was sent to three tombs by Theras, Aletheia appearing at the entrance of each, in order so Layla, acting as the Heir of Memories, would be able to unlock the gate to Atlantis. During Layla's exploration of three tombs, Aletheia revealed that she had a consciousness kept within the Staff, able to communicate with Layla and listen to frequencies, speaking of a currently unidentified male "interloper" who was interfering with the communications frequency between the Altair II and Layla.[5]

After the gate to Atlantis was unlocked, Aletheia appeared as a projection to Layla, and later to Victoria Bibeau, instructing that Layla synchronise with Kassandra's experience of Aletheia's custom built simulations in order to unlock the full potential of the Staff of Hermes Trismegistus.[5]

When three members of Sigma team attacked, Layla remarked that Aletheia had turned tail, and as such is nowhere to be found after the attack.[5]


In 431 BCE, when the misthios Kassandra visited the Ancient Forge on the island of Andros, Aletheia spoke to her, acting as the system voice for the Forge as it upgraded the Spear of Leonidas.[6]

Aletheia's recordings on the Olympos Project was later discovered by Kassandra, who traveled to the vault in search of her father, Pythagoras.[4]

In 2018, Layla Hassan kept a record of her findings about Aletheia on her laptop.[1]
