The Paper House is a model haunted house in The Hunter, but also the location where Julian physically transports Jenny and her friends to play his game. It seems to exist somewhere between the real world and the Shadow World because it's suggested that the location was destroyed when the model paper house was.
The House has an ever-changing interior that's based on the memories of the players, but is roughly three floors and a turrent high. Each floor has several doors that lead to a character's nightmare.
The first floor is a Victorian parlour. The players start here, and there are no nightmares on this floor.
The second floor is based on the Haunted Mansion in Disneyland, California.
The third floor is a hall of mirrors.
The turrent is based on the More Games store in which Jenny first met Julian.
