Pishacha
Region of origin: India
Ghoulish creatures that manifest after an evil or sinful human has passed on but their spirit lingers on earth, often residing near cremation grounds. They come out at night and can possess humans they encounter, feeding off their life energy and driving them to madness or compelling them to commit violent, wrathful acts.
