Altaïr Ibn-La'Ahad (1165–1257) was a member of the Levantine Brotherhood of Assassins who served as their mentor from 1191 until his death in 1257.
Thanks to knowledge of the Apple of Eden, Altair made several discoveries and inventions that greatly helped the development of the Order. His leadership took care of spreading the influence of the assassins throughout Europe and Asia.
Raised as an Assassin from birth, Altair became a Master Assassin at the age of 24.
