Assassin's Creed

Desmond is captured by Abstergo and forced to use a machine called the Animus to explore Altair ibn-La'Ahad's memories during the time of the Third Crusade. Desmond begins to witness events after Altair breaks all three tenets of the Assassin Brotherhood while attempting to stop Robert de Sable from taking a Piece of Eden. Al Mualim, the Brotherhood's leader, demotes Altair to Novice and tasks him with assassinating the nine Knights Templars, including de Sable, to regain his former status. Altair's quest eventually leads him to face de Sable in the presence of King Richard I of England warning the King of de Sable's plot to kill him. Altair defeats de Sable, but with his last words, de Sable reveals that there were ten Templars, the last being Al Mualim, who now holds the Piece of Eden. Altair returns to face Al Mualim, struggling to fight through the illusions created by the Piece, but eventually kills Al Mualim. When Altair recovers the piece, he - and those watching the Animus - witness a holographic map showing locations across the globe where other artifacts are located. Desmond is pulled from the Animus, and was going to be killed, but his life is spared by Lucy Stillman, an Assassin working as a mole within Abstergo, as she claims they might need to further examine his memories later. He comes to learn that a former test subject had left messages only Desmond can see, foretelling of the end of the world in 2012.
