- "A dark tide rises to the east – an army of such size and power that all the land is made quick to worry. Their leader is a man named Temujin, who has adopted the title Genghis Khan. He sweeps across the lands, conquering and subsuming all who stand in his way."
- ―Altaïr Ibn-La'Ahad's Codex, page 29.[src]
Temujin (c. 1162 – August 1227), also known under the title Genghis Khan, was the founder and first emperor of the Mongol Empire, which he ruled from 1206 until his death.
By the year 1217, the Mentor of the Levantine Assassins, Altaïr Ibn-La'Ahad, suspected that Genghis Khan's rise to power was due in part to his possible ownership of a Piece of Eden, presumably one of the Swords. Altaïr, his wife Maria, and his son Darim traveled to Mongolia intending to assassinate Genghis Khan, and to retrieve the Piece. In 1227, the Mongolian Assassin named Qulan Gal shot Genghis Khan's horse with a bow and arrow, dismounting the Mongol Emperor and providing Darim the chance to kill him with a crossbow bolt.
