Fan Casting Rashid ad-Din Sinan in Robin Hood and the House of Plantagenet (TV-Series)

The legendary "Old Man of the Mountain" and the feared Grand Master of the Hashshashin (Assassins). Operating from his impregnable mountain fortresses, Sinan is a wild card who plays both sides of the Crusade to ensure the survival of his sect. He uses terror as a precise surgical tool, turning the tide of the war with a single blade in the dark. To him, kings and sultans are merely temporary actors in a divine play, and he is the shadow that ensures none of them become too powerful to control.
