Aya is the first name of Bayek's wife in Assassin's Creed Origins.
Aya and Bayek are Medjay from Siwa who become central figures in the origins of the Hidden Ones, the organization that later develops into the Assassin Brotherhood. Their personal story is set during the Ptolemaic period of ancient Egypt, amid a struggle involving Cleopatra, Ptolemy XIII, and Roman power.
Aya is not merely a supporting character. She is playable in several sequences and has her own political and military connections, including ties to Cleopatra and Julius Caesar. Her actions help shape the organization and its long-term methods.
The name can be confused with characters from other games, especially Aya of Alexandria, whose role is sometimes shortened in casual discussion. Bayek remains the primary playable hero, but Aya's choices are essential to the formation of the Hidden Ones.
