In Assassin's Creed, what is the name of the protagonist who serves the Levantine Brotherhood?

In Assassin's Creed, the protagonist serving the Levantine Brotherhood is Altaïr Ibn-La'Ahad.

Altaïr is the central playable character in the first Assassin's Creed game, released in 2007. He is an Assassin operating in the Levant during the Third Crusade, with missions taking place in cities including Masyaf, Jerusalem, Acre, and Damascus. His initial failure during a mission causes him to lose rank and equipment, forcing him to rebuild his reputation under the guidance of Al Mualim.

The game follows Altaïr as he investigates and eliminates a series of politically powerful targets. His experiences gradually challenge his assumptions about obedience, power, and the Assassin Creed. The story also establishes the enduring conflict between the Assassins and Templars that defines the broader series.

Altaïr should not be confused with Ezio Auditore, the Renaissance-era hero of the next major storyline, or Connor and Edward Kenway, who are protagonists of later games. Altaïr's full name is commonly written with the Arabic transliteration “Ibn-La'Ahad,” meaning “son of no one.”
