Al Mualim mentors Altaïr at the beginning of the original Assassin’s Creed.
Al Mualim is the leader of the Assassin bureau in Masyaf, the mountain stronghold that serves as the Brotherhood’s headquarters during the game. After Altaïr breaks the Assassin code during a mission, Al Mualim strips him of his rank and equipment, then assigns him a series of targets as a path toward redemption.
The name Al Mualim means “the teacher” or “the master” in Arabic transliteration. In the story, he instructs Altaïr while also directing the Brotherhood’s operations during the Third Crusade. His relationship with Altaïr changes as the investigation reveals more about the Templar conspiracy and the Apple of Eden.
Al Mualim is not Altaïr’s father or a modern-day mentor. William Miles fills a major leadership role in the modern Assassin network, while Achilles Davenport mentors the later protagonist Connor Kenway. Those characters belong to different periods and storylines.
