The Hurricane is an area within the Appalachian Mountains of Virginia that locals try to avoid. This is not without justification as it is a hothouse of supernatural activity. It contains coal mines with deformed Melungion witches, houses the sabbath of regular witches, and the home of Jeremiah Witkins.
Reverend Watts' church also stands in the area, a battered bastion against the threats therein.
The Hurricane was one of the first settled areas in that location. Native Americans tended to avoid the area though, so it doesn't take a leap of the imagination to conclude it has been a supernatural hotbed for many centuries.
