Kassandra is the canonically intended playable protagonist of Assassin’s Creed Odyssey.
At the beginning of Odyssey, players can choose to play as either Kassandra or Alexios. Ubisoft later established Kassandra as the canonical protagonist, while Alexios is used as Deimos, the opposing sibling in the main storyline. Both choices follow the same broad historical setting and many of the same narrative events, but the canon novelization also uses Kassandra’s story.
Odyssey is set in ancient Greece during the Peloponnesian War, beginning in 431 BCE. Kassandra is a Spartan mercenary and descendant of Leonidas I. Her journey involves the Cult of Kosmos, the family’s divided history, and the ancient Isu legacy connected to the Staff of Hermes Trismegistus. Kassandra should not be confused with Phoibe, a young ally, or Myrrine, Kassandra’s mother. Odyssey takes place before the events of Assassin’s Creed Origins.
