In Assassin’s Creed Origins, Bayek’s home at the beginning of the story is the Egyptian settlement of Siwa.
Siwa is an oasis in Egypt’s Western Desert, far from the Nile Valley’s major cities. In the game, Bayek serves as the local medjay, a protector and law-enforcement figure whose duties connect him closely with the community. The opening chapters establish his family, responsibilities, and conflict with powerful outsiders.
The real Siwa Oasis lies near the border with Libya and is historically known for its distinctive culture and the Temple of Amun. Assassin’s Creed Origins uses the settlement as both a narrative starting point and an explorable region.
Siwa is not the same as Alexandria, Memphis, or Cyrene. Those larger ancient cities appear elsewhere in the game and have different historical and geographic roles. Bayek later travels widely as he investigates the forces threatening Egypt.
