he's a demon.. the episode itself comes from the legend of witch's Familiars, which are demons.. not quite Lovecraftian as it can be explained (and is explained in the episode) - it's a curse gone wrong.. hence magic.

demons don't have to come from Hell, they are just magical beings with more power than "monsters" but usually less power than "deities" or "cosmic entities".
