In Assassin's Creed, Altaïr Ibn-La'Ahad's first target in Damascus is Tamir. Tamir is a wealthy arms merchant operating in Damascus's Poor District during the Third Crusade. Altaïr must investigate the target, identify the evidence linking him to the Templars, and then carry out the assassination.
The mission introduces the game's investigation structure. Altaïr gathers information by pickpocketing, eavesdropping, and completing informant tasks before confronting Tamir in his trading area. Tamir's behavior toward a desperate merchant also reveals his ruthlessness and helps establish the moral framing of the target system.
Tamir is one of nine major targets assigned to Altaïr by Al Mualim. He should not be confused with Robert de Sablé, the Templar Grand Master, or with Al Mualim, who leads the Masyaf Assassins. The Damascus mission is the game's first major assassination after the opening sequence.
