Sparta is the ancient Greek city-state associated with Kassandra's early life in Assassin's Creed Odyssey.
Kassandra is raised in Sparta and begins the game as a mercenary in the Aegean world. The story later takes her across many regions during the Peloponnesian War, including areas aligned with both Athens and Sparta. Players can choose Kassandra or Alexios as the playable character, while the other appears as an important character in the story.
The game is set in 431 BCE, at the beginning of the Peloponnesian War. Athens is a major location and political power in the campaign, but it is not Kassandra's early home. The historical setting combines real places and figures with the series' fictional Isu mythology and branching role-playing structure.
