After a mission to Solomon's temple which led to death of one of his companions Altair was demoted and had to work his way back to ranks (its all an excuse to teach you new skills). He is a young skilled assassin, but also an argonant man. In 1191 the playable character is Altaïr Ibn La-Ahad, an assassin. Abstergo place him in a machine called the Animas and the theory behind it was that DNA also contends the memories of out ancestors. In 2012 the main character is Desmond a former assassin who is kidnapped by a company called Abstergo who wanted to access the memories of one of his ancestor. The game has a strange premise, it is both set in 20 and you play two characters. Assassin's Creed is basically a cross between Grand Theft Auto and the Hit-man series set during the Third Crusades.
