Desmond Miles, a bartender, is kidnapped by the company Abstergo Industries for use as a test subject in the "Animus," a device that can simulate genetic memory. Abstergo intends to put Desmond in the device to recall the memories of his ancestor, Altaïr Ibn-La'Ahad, a member of the Assassin Brotherhood in the year 1191, who lived during the Third Crusade in the Holy Land. Initially, Desmond has trouble adjusting to the device, but eventually relives Altaïr's exploits over the next several days. The game then primarily changes to Altaïr's point-of-view, with occasional transitions to Desmond, due to problems with the Animus or onset of the Bleeding Effect.
