After Sue makes a right, the walls inexplicably slam shut behind her. A forty feet stretch of floor in front of her splits in half, and as each half recedes into the wall, a pool of water appears twenty feet below her. Just below where the floor originally was, ten tiles jut out from the sides of the pit. The are twenty inches long and ten inches wide, and tilt downward at a fifty degree angle. They are placed at varying distances from each other, and in the water below, small dark forms can be seen thrashing around. Suddenly, the lights in the hall way begin to vary in brightness. Near Sue, the light is as it was before, but as the lights grow dimmer every few feet until complete darkness blankets the last two tilted tiles and the end of the hallway.
