Who is the playable protagonist of Assassin's Creed Mirage?

Basim Ibn Ishaq is the playable protagonist of Assassin's Creed Mirage.

Mirage follows Basim in ninth-century Baghdad, where he develops from a street thief into a Hidden One. The game serves as a character-focused prequel to Assassin's Creed Valhalla, which introduced Basim as an important figure in Eivor's story.

Baghdad is presented during the Islamic Golden Age under the Abbasid Caliphate. Basim's missions emphasize stealth, parkour, investigation, and targeted assassinations, reflecting the structure of earlier Assassin's Creed games while using modern series systems.

Basim is not Bayek, the Medjay hero of Origins, nor Arno Dorian, the Assassin of Unity. Edward Kenway is the pirate protagonist of Black Flag. These characters belong to different historical periods and games, making Basim's identity specific to Mirage's ninth-century narrative.
