I found it at Wikipedia .com and this is what it said''Scythe - An ancient Hero, Scythe is one of the oldest beings in Albion; only Jack of Blades has seen and done more. Obsessed with cheating death and kept alive only through supernatural means, Scythe is a withered shell of a man, resembling a tall, mummified corpse. At the beginning of the game, he leaves for the distant Northern Wastes to guard the Oracle of Snowspire. In Fable: The Lost Chapters, Scythe returns after the defeat of Jack of Blades to seek the Guild's help in battling a new threat to the Northern Wastes. He is the only Hero in the game the player is never given the option of killing'' I guess it doesn't really say he's immortal , but it sure sounds that way.
