Sehn is a creature made up by a friend of mine. They are heartless men, who have sworn an Oath of Heart, which has been broken. They are cursed to go to Murheen Maat (Lands of Grief), where they are tormented, blinded and ripped of their humanity. They are beasts of eternal hunger, without any emotions besides hunger and longing. They live forever if not killed by some paladin, but their life is an empty one. Their sole purpose is to wander after food, which, far too often, happens to be human beings... Sweet, isn't it?
