Pishacha/Pisacha

The Pishacha flesh-eating ghouls from the myths of India. They rise from the grave because they are trapped between heaven and hell, incapable of moving on or redeeming themselves. They take out their anger on humans who are still capable of redemption. Due to their supernatural nature, they have a great understanding of the past, present, and future. Oftentimes they’re imprisoned by sorcerers who use this knowledge to their advantage. Can be killed with normal weapons physically, though it will continue to haunt the location where their physical form is destroyed. They can be forced to move on if one has a holy sage and the Pishacha’s true name. The name can be used in a burial rite after killing the Pishacha with a sword. It is difficult to find its true name since Pishacha rarely resembles themselves in life. After this ritual, they are freed and can move on, but it’s uncommon for this to happen.
