An archway to the east opens onto a rounded plateau overlooking a steady stream of raw sewage, pouring from a drainage tunnel to the south. The air is thick with the rancid, oppressive stench of humanoid waste as it slides northward into a second tunnel, this one blocked off with a rusted iron grate. A sign has been hung over the canal, coated with sloppy red paint on a tattered board.
