In Assassin's Creed Origins, Alexandria is the ancient Egyptian city home to the game's Great Library.
Origins is set mainly in Ptolemaic Egypt during the first century BCE. Alexandria was a major Mediterranean center of scholarship and commerce, and the game depicts its famous Library and the nearby Mouseion as important landmarks. The city is also associated with the Pharos lighthouse, one of the ancient world's celebrated wonders.
The protagonist, Bayek of Siwa, travels through Alexandria during his investigation into a hidden order that threatens Egypt. The city contrasts with rural settlements and desert regions, giving the game a broad visual and cultural range.
Players sometimes select Memphis or Siwa because both are important Origins locations. Memphis is a major ancient religious center, while Siwa is Bayek's homeland and the location where the story begins. Neither is the city associated with the Great Library in the game.
