Bayek of Siwa, the protagonist of Assassin's Creed Origins, comes from the oasis town of Siwa.
Bayek is a Medjay, a protector and law enforcer in ancient Egypt. The game begins in the Siwa Oasis, where his personal quest develops into a wider struggle involving political factions, Roman influence, and the origins of the Hidden Ones.
Siwa lies in Egypt's Western Desert near the Libyan border. Its location made it a distinctive starting point for the game, contrasting with later journeys through cities, farmland, deserts, and the Nile Valley. The historical Siwa Oasis was also known for the Temple of Amun and its oracle.
The title Origins explores the beginnings of the organization that later becomes the Assassin Brotherhood. Players sometimes answer Alexandria because it is a major city in the game, but Alexandria is a later destination rather than Bayek's home. Memphis and Cyrene are also important locations, but neither is his birthplace.
