From publisher blurb:
The Grand Stair stretches behind the scenes of the multiverse,
The Doors upon its unfathomably vast span leading the way to gossamer worlds of limitless variety and infinite possibility. Out there somewhere is a place for every dream... and every nightmare.
The Nightmare Kingdom is a realm of pure fear, capable of warping its highly mutable fabric to take the shape of anyone's darkest dreams - or spinning newly crafted horrors as of yet unimaginable. In that sadistic playground beyond compare, the gruesome Ghoul toys with its hapless victims, feeding upon their fright as they stumble through the sinister scenery pursued by the realm's monstrous boogeymen. Ancient, primal, and terrifyingly powerful, the Nightmare Kingdom bends the rules of gossamer reality to the breaking point, twisting so hard you'll scream.'
