In Assassin's Creed Origins, which Medjay from Siwa becomes the central protagonist?

Bayek of Siwa is the Medjay from Siwa who becomes the central protagonist of Assassin's Creed Origins.

The game is set in ancient Egypt during the first century BCE, around the period of Cleopatra's struggle for power. Bayek is a protector of the Siwa Oasis and begins a personal investigation after a traumatic attack on his family. His journey takes him across Egypt and leads to the formation of the Hidden Ones, the organization that later develops into the Assassin Brotherhood.

Aya of Alexandria, Bayek's wife, is also a major character and an important founder of the Hidden Ones. She should not be mistaken for Bayek himself. Senu is Bayek's eagle companion, while Khemu is his young son.

Origins was released in 2017 and reworked the series with role-playing systems, equipment levels, quests, and a large exploration-focused map.
