Baghdad is the central setting of Assassin's Creed Mirage.
Mirage takes place in ninth-century Baghdad during the Islamic Golden Age. The city is divided into districts with distinct landmarks, markets, institutions, and political influences, allowing the game to connect Basim's personal story with the wider history of the Abbasid capital.
Basim Ibn Ishaq is the protagonist. The narrative follows his transformation from a street thief into a member of the Hidden Ones, the historical organization that predates the later Assassin Brotherhood. This makes Mirage a character-focused origin story within the broader franchise chronology.
Baghdad is sometimes confused with Damascus, Jerusalem, or Cairo because those cities appear in other Assassin's Creed settings. Damascus and Jerusalem are prominent in the original game, while Cairo is associated with several other historical periods and series locations.
