Bhut

Especially in areas of intense magical activity, corpses rarely stay dead for long. The Bhut is a result of a creature dying violently and suddenly, far from home. One of the more lively forms of undead, a Bhut is actually a formless spirit with the ability to inhabit dead bodies. Whilst it takes to its adopted form with some vigor it is not known for its finesse, and takes some creative decisions with the flesh of its host. Appearing as a horrible cloud of gristle, blood and bone, the Bhut aggressively attacks any who approach it.
