In Assassin's Creed Revelations, which city is Ezio's primary base of operations?

In Assassin's Creed Revelations, Constantinople is Ezio's primary base of operations.

Ezio travels to Constantinople, the capital of the Byzantine Empire, while searching for keys connected to Altaïr Ibn-La'Ahad's legacy and the Masyaf fortress. The city provides the main setting for the game, with districts controlled by Byzantine Templars and missions that take Ezio across its neighborhoods and waterways.

The story is set in the early sixteenth century, chiefly in 1511 and 1512. Ezio works with local Assassins, including Yusuf Tazim, and encounters figures such as Suleiman, the Ottoman prince. The game also includes playable sequences from Altaïr's life, creating the connection between the first protagonist and Ezio.

Masyaf is crucial to the plot because of Altaïr's library, but it is not Ezio's main operating city. Jerusalem belongs primarily to the setting of the original Assassin's Creed, while Alexandria is strongly associated with Origins.
