Harry Potter: Demon Lord? Nah, I'm Just A Dementor

Dementors are dark magical creatures that have no facial features and can only distinguish living people by smell and emotion floating in air. Wherever they go, happiness disappears, leaving the deepest fear in people's hearts and there's even saying that under the hood of the dementor there is a face that can devour souls. Alan Norton, who had become a dementor in human skin could not deny any of this as his craving for soul began to increase.
