Walls of black marble streaked with ice-blue enclose the circular chamber. A heavy armchair upholstered in midnight-blue velvet sits behind an intricately carved ebony desk. Blue silk tassels and fine blue fringe adorn the dark velvet draperies covering most of walls. Heightening the dramatic darkness of the room by way of contrast, a swirling iridescent cloud hovers against one wall like a mist-filled door.
