The woman appeared to the Jamestown settlers just as they were beginning to starve. They assumed she was sent by a local native tribe, though her true tribe was far older and far more removed from the world than anyone knew. Using her blood magic, she saved the lives of the injured and dying colonists. Though they feared her, they were grateful, and left her alone... until the day she suggested the village elders stop hoarding the food and share it freely amongst the colonists and even with the native tribes.
At this, the colonists declared her a witch and plotted to hang her. The woman discovered it quickly and retaliated with a curse: the hoarding colonists would no longer be sustained by ordinary food. The only thing that would now satsify their hunger was the taste of human flesh... and not just any flesh. Only the flesh of their own blood relatives.
Before condemning the colonists to madness and death, the woman said: "And thus did Roanoke meet this same fate. I had hoped you would be different."
