A Pain Eater is an Under Fae.
The appearance of a Pain Eater is a tall and bald disfigured being with pronounced facial features and long fingers, from which long pointed nails extend. It possesses telepathic abilities and can project images into a victim's mind by touching their temples. The Pain-Eater can convince the hypnotized individual to harm himself or others.
When the Pain Eater enters a victim's subconscious mind, it appears as a friendly, elderly humanoid man.
Despite their apparent intelligence and powerful telepathic abilities, they are Under Fae because of their inability to blend physically among humans and be undetected.
