A creature from its own pocket dimension, Dem takes pleasure in manipulating and tricking every living being he finds into his world, promising to fulfill their desires and grant them happiness, for a price, of course, granting a wish for your eyes and sew buttons into your eye sockets and come with him in exchange. His true name, story, age or bio are a mystery. He cannot sense darkness and is as blind to it as any human. However, his darkness cannot be manipulated, as he doesn’t have any.
