Twin Pine Journey - Twin Pine Casino & Hotel, Napa Valley

A haunted mansion with a twist, it was touched by the shrouded king, an inter-dimensional being of darkness, now the mansion acts as a pocket dimension with seemingly infinite rooms, and phases through time and space, having been photographed before it was technically created....

Mythgirl

1. The lotion room: Dozens if glass shelves hold hundreds bottles of lotion. Footsteps are muffled against the leather floor. The walls are made of living skin hidden behind thin wood panels which fold out of the way like shutters.
   
2. The crime scene: A manikin lies motionless inside of a chalk outline. The decor is that of a seedy motel. Flies buzz lazily, crawling in and out of the the sink’s plumbing. Upon inspection a few strands of hair are found in the drain. If you pull them they slide out, slimy and damp, attached to a piece of scalp.
   
3. The powder donut: a room with opulent furnishings. Overstuffed chairs and sofa’s welcome visitors. If sat upon, they release a white cloud. Poison? Mold? Anthrax? Powdered sugar? Mites? Only time will tell the effects.
   
4. Abandoned room: all the furniture is covered in sheets. If lifted, nothing but dust is found under the cover.

18. Statue room (full of statue figures)
    
19. Portrait room (full of portraits)
    
20. Sculpture room (not figures, more artistic)
    
21. Room of stone where everything is made of marble
    
22. Golden room (painted or real you decide)
