Gehenna, also know as "The Four Fold Furnaces", is the evil Outer Plane of perpetual fumes, magma, and rock. Gehenna is one continuous climb up the side of a never-ending, massive, volcanic cliff. On the surface of the volcanoes, it gets so blistering hot that creatures' eyes boil from their skulls, meaning that most life in Gehenna resides within various cracks and crevices carved into the surface of these volcanic cliffs.
