Assasin's Creed; A New Threat? Or A New Ally?

Taking place primarily during the Third Crusade in the Holy Land in 1191,details emerge about a centuries-old struggle between two factions: the Assassin Brotherhood, who fight for peace with free will, and the Knights Templar, who desire peace through control.

Both factions seek an artifact called the "Apple of Eden", which can be used to control minds, with the Assassins wishing to destroy it before it can be used for evil.

The 12th century story follows Altaïr, a high-ranking member of the Assassins, who after breaking the tenets of the Brotherhood during a botched mission, must assassinate a select group of targets to regain his lost honor. The world comprised of four cities-Masyaf, Jerusalem, Acre, and Damascus. Mostly in the Levant.

But along the way Altair met someone, someone from the Southeast. This someone gets on Altair's nerve most of the time because of his way of thinking. But after Altair retrieve an Apple of Eden from Jerusalem, Altair's view towards him begun to change.
