EditJourney to Mongolia
When Genghis Khan's empire kept expanding rapidly, Altair suspected that he had a Piece of Eden with him that enabled his conquests and took Maria and Darim on a mission to Mongolia to end him. They arrived in 1227 and after a failed attempt to take his life, Genghis Khan attempted to flee by horseback. However the horse was shot down by Mongolian Assassin Qulan Gan and Darim managed to kill Genghis with a crossbow.
EditReturn to Masyaf
When Darim and his family returned to Masyaf, Darim was told that his brother Sef and his family fled to the town of Alamut. But when Darim arrived there he learned from his in-laws that Sef was killed and rushed back to Masyaf to alert his father. Altair was fighting off guards when Darim arrived and revealed to him that his mother Maria was also killed when he went to see Abbas who gained power in Altair's absence. They both manage to flee Masyaf and they lived in exile for twenty years until the day Altair returned to Masyaf to reclaim it and the Assassin order from Abbas.
