In Assassin's Creed Revelations, which historic city serves as Ezio's principal base?

Constantinople is Ezio's principal base in Assassin's Creed Revelations.

Released in 2011, Revelations follows Ezio Auditore as he travels to the capital of the Byzantine Empire. The city, also called Istanbul in modern usage, is divided into districts and forms the central hub for much of the campaign.

The story also connects Ezio's journey with Altaïr Ibn-La'Ahad through the Masyaf keys. Constantinople's location between Europe and Asia supports the game's emphasis on cultural contact, political rivalry, and the legacy of earlier Assassins.

Alexandria is the main setting of Assassin's Creed Origins, while Jerusalem is strongly associated with the first game. Athens appears in Assassin's Creed Odyssey, but it is not Ezio's principal base in Revelations. The game's historical period is the early sixteenth century, shortly before the Ottoman conquest of Masyaf's region becomes part of the narrative background.
