Papa Dyaman (Papa Diamond) is a madman!

 

He lived his mortal life from 1765 to 1809.  Using Vodou magic, he fought in the Isle de Lakwa's revolution, helping his fellow captives win their freedom and take control of the island.

 

Though he died in 1809, he lives on.  Dyaman's consciousness resides in a skull made of diamond.  He takes control of the recently dead, to give himself a temporary body.
