William Miles (non-canon)

William Miles was a member of the Assassin Order and the father of Desmond Miles.

William lived with his family in a desert community, sometimes taking his son on trips through the barren wasteland surrounding their home. During one such trip, when they were watching an eagle in flight, William warned his son to always be careful of the "vultures", referring to the Templar Order.
