In Assassin’s Creed Origins, Bayek of Siwa’s official role is a Medjay.
A Medjay is a protector and law-enforcement official in ancient Egypt. Bayek serves as the Medjay of Siwa, a position that gives him responsibility for protecting local people and resolving disputes. His personal investigation into the murder of his son draws him into a much wider political and religious conspiracy.
Origins uses Bayek’s story to depict the formation of the Hidden Ones, the organization that later becomes the Assassin Brotherhood. His wife, Aya, is also central to the group’s creation and its early activities across the Ptolemaic Kingdom.
The word “Medjay” originally referred to a Nubian people and later became associated with elite guards or protectors in Egyptian history. The game turns that historical term into Bayek’s profession, so it is not the name of a rank such as pharaoh or vizier. Bayek remains known as the Medjay of Siwa even as his adventures take him far beyond the oasis.
