Which Assassin's Creed game stars Bayek of Siwa?

Assassin's Creed Origins stars Bayek of Siwa.

Bayek is a Medjay, a traditional protector of Egypt, and the game's story follows his search for those responsible for a personal tragedy. His journey unfolds during the first century BCE, when Egypt is ruled by the Ptolemaic dynasty and political power is contested by figures including Cleopatra and Ptolemy XIII.

Origins explores the formation of the Hidden Ones, the organization that later develops into the Assassin Brotherhood. Bayek and Aya are central to that transformation, although the game does not portray the Brotherhood in its later, fully established form.

The setting is ancient Egypt, while Odyssey focuses on ancient Greece and Valhalla follows Viking-era England and Norway. Those games share the broader franchise but have different protagonists and historical periods.
