Name: Ephemeral Plains of Ill Repute

Geography: Dominating the plains is the [i]Plateau Encephalon,[/i] a sagging, disgusting mound of moist flesh-soil with an enormous grimacing mouth-canyon. A thousand rows of black-gummed teeth gnaw and gnash for eternity anything that slips into the canyon. Stretching out from the Mouth are veiny black ravines and tunnels that stretch to the furthest reaches of the Plain. These labyrinthine paths change and shift frequently, and ultimately lead any creatures to the Mouth for consumption.    

Method of Recycling Matter: The Mouth at the center of the Plateau Encephalon deposits matter into the vast subterranean intestinal complex known as Damnation. Depending on the size of the matter (and the resilience) it may take centuries or hours for something to be consumed and returned to the Plains.
