For those who have the psychic capability to see spirits,  this stone will overlay the astral area of the property it is on with a Halloween landscape, transforming the house's astral image into that of a haunted mansion, with spooky graveyards and twisted trees.  It will be inhabited by an array of creepy creatures, ghoulies, and ghosties that may be born, grow, die (and maybe get back up again), and continue changing over time.

In addition to the standard house Guardian capabilities, this guardian will defend any building the stone is placed in from hostile psychic intrusions by those who do not belong and were not invited there by the rightful occupants.  It can create a formidable variety of house shields, and also extends its protection to all of the people who are legitimately inside the building, and is affectionate toward them.  It also has all of the abilities of the creatures that are part of it, including werewolves, zombies, vampires, and other creepy entities.  As with all of our realm guardians, this house guardian can withdraw its realm projection at the owner's request.
