Athens is the ancient city identified as Socrates' birthplace in Assassin's Creed Odyssey.
Odyssey is set in 431 BCE, during the Peloponnesian War between Athens and Sparta. The game includes historical figures such as Socrates, Pericles, and Hippocrates, placing the player in a fictionalized version of classical Greece.
Socrates was an Athenian philosopher, and the game presents him in Athens while adapting his documented life into quests and conversations. The playable protagonist can be Kassandra or Alexios, but that choice does not change the historical setting.
Odyssey is not the same game as Origins, which is set in Ptolemaic Egypt. It also uses an earlier period than Valhalla, whose main historical events occur in ninth-century England.
