In Assassin's Creed Revelations, Ezio Auditore is the main historical playable character.
The game concludes Ezio's central storyline as he travels to Constantinople, the capital of the Byzantine Empire, in search of Altaïr Ibn-La'Ahad's lost library. Ezio is older than in the previous games, and the narrative explores his attempt to understand the legacy of the Assassins rather than simply pursue personal revenge.
Players also control Altaïr in several memory sequences. These sequences show important stages of Altaïr's life after the events of the first Assassin's Creed, including his leadership of the Brotherhood. The presence of both characters is why the title is sometimes mistaken as an Altaïr-led game.
Revelations was released in 2011 and is the third main game centered on Ezio, after Assassin's Creed II and Brotherhood. It also continues the modern-day storyline of Desmond Miles and includes the hookblade as a major traversal tool in Constantinople.
