Gehenna

Today's map is the plane of Gehenna, Formed out of four impossibly huge volcanoes floating in an endless black void, with little open ground anywhere. The slopes are always in between a 45 degree angle to a full-on cliff face. Aside from the rocky and soot-stained walls, the dangerous terrain (lava, the River Styx, acidic ash) and the hostile inhabitants (Yugoloths and other fiends) make Gehenna a thoroughly unpleasant place.
