I was just wondering as this was their original killer of vampires, would it have a unique effect? You know how when an original dies, their bloodline dies as well. What if a normal vampire staked with the WOS, he and evey vampire descended from him dies.
This vampire king called Marcel, most if not all of his vampires, especially his day walkers would be descended from him. Say my theory is correct, it would eliminate most of the vampire threat in New Orleans.
