You are racing down a dimly lit hallway. Behind you great bulks move through the murky light. A thousand legs with beetle's bodies, horse's cocks, and the face of your mother screaming in anger and pain. You aimlessly race through the mist always a step ahead but only because they enjoy the chase.  You search for a door, a window, anything but the uniform grey walls.  At last you see a light in the distance.  You pull ahead, strength renewed by hope, and beat your pursuer to the open doorway by a good ten feet. You stop yourself just in time as you feel the cool breeze touch you face.  The doorway looks out upon a huge crater with red rock walls. You can see similar doorways lining the walls with figures similar to yourself being ripped apart monsters or leaping in to space.  Five hundred feet below is a lake of boiling green fluid choked with human bones and metal spikes and blades the jut upwards several meters.  You can hear the things behind you, feel and smell their hot fetid swamp breath at your back.
