Which Assassin’s Creed game introduced the playable character Bayek of Siwa?

Assassin’s Creed Origins introduced the playable character Bayek of Siwa. Bayek is a Medjay, or protector, from the Siwa Oasis, and the game follows his efforts to defend his family while uncovering the origins of the Hidden Ones.

Origins is set in ancient Egypt during the first century BCE, amid the political struggles involving Cleopatra, Ptolemy XIII, and Julius Caesar. Its story presents the Hidden Ones as the organization that later develops into the Assassin Brotherhood. The game also changed the series with role-playing systems, leveled equipment, and a large exploration-focused world.

Bayek should not be confused with Kassandra, the playable protagonist option in Assassin’s Creed Odyssey, or Eivor, the central character in Assassin’s Creed Valhalla. Origins is the specific title that introduced Bayek and his wife, Aya.
