The main plot line of the series is the unseen power struggle between two factions, the Assassins, modelled after the real-life Ismaili Nizaris, and the Templars, modelled after the Order of the Knights Templar, a war that has been going on throughout human history, behind closed doors and without the general population’s knowledge. This chapter demonstrates that by employing both instances of revived pasts as well as of recreated pasts, as well as by playing on the subject of memory, Assassin’s Creed in fact hides a deeper concern very relevant to the modern world: the opposition between freedom and oppression of thought. In the Assassin’s Creed universe, both the Assassins and the Templars are searching for the Pieces of Eden, ancient mysterious objects that possess supernatural powers. Geographically, the environment in which Altair Ibn-La’Ahad moves consists of Masyaf, the Assassins’ headquarters, the cities of Jerusalem, Damascus, and Acre, and a middle ground that connects them called 'The Kingdom'.
