In Guinea, Africa, there’s a vampire spirit called Ovengua (pronounced Ov-in-way).
When an evil sorcerer dies his bones begin to escape from his grave. One bone at a time they gather in a secret location. When all the bones are together the skeleton will realign and become an Ovengua, the only difference is it has hooks for hands.
This vampire skeleton hides during the daylight hours, and hunts at night, attacking lone travelers. Not to drink blood but to process the body.
If it wins the fight to control the traveler’s body, it will kill the traveler and reanimate the body as its own.
The Ovengua can’t be killed on its own. It must pocesses a body and both body and Ovengua will be killed and burned to ash.
