While the qualities of Gehenna are widely known — massive fragments of rock, of varying levels of volcanic activity, floating in an infinite void — the core nature of Gehenna is less so. Gehenna is nothing less than the plane of the apocalypse, of the violent end of worlds upon the Prime. To paraphrase a Prime poet, some of these worlds have ended in fire, others in ice. But they all have ended. Shattered, crumbled, rent asunder by the actions of those that have dwelt upon their surfaces. And that which remains dumped into the Furnace of Perdition. As the Beastlands show the gentle harshness of the land before the touch of sentience, Gehenna shows what remains from its hubris. It is said that this dark is the reason the yugoloths have such great interest here; that they desire to pick over the remains of countless civilizations, to collect the lost knowledge powerful enough to bring end to any number of worlds.

Physical Conditions

The layers of Gehenna are each made up, as described above, of massive planetary fragments, ranging from a few inches across to thousands of miles. Earth worlds, being the most likely to suffer such a cataclysm, make up the vast majority of Gehenna, but on occasion one can find the undulating remains of a Water world, or a massive glob of a Fire world mistaken for erupted magma; the remains of Air worlds are likely to manifest here too, though any such would probably be indistinguishable from the native atmosphere. For those planets large enough to form a gravity shell, gravity points to the center of the fragment, meaning that for the most part level ground is at an absolute premium; most ground ranges in slope from as shallow as 5 degrees to as steep as 80. On the steepest surfaces, one must be careful in maneuvering, as it is quite easy to build up enough speed in a fall to tumble off into the void entirely.

Most of the very largest fragments in Gehenna still have the lifeblood of worlds running through them, magma running hot in their depths. This activity makes for the sole natural source of light and heat in the plane, leading to very different experiences throughout the layers. On all of them, though, any natural light is a dull red, the radiation of the liquid rock and slag that so often erupts to the surface. Because of their role here, those locations where it does breach the surface, flowing free above ground, are the areas colloquially known as "furnaces". They are most common upon Chamada, where the most blatant volcanic activity is to be found.

The layers of Gehenna are of ascending age, those fragments in Khalas of the most recent disasters, and those of Krangath the oldest. As a fragment ages, it sinks relative to the others, and given enough time it transitions over into the next. The actual process of transition has never been observed; it seems to occur only when unobserved from the outside.

Magical Conditions

Abjuration	No change
Conjuration	Summoning spells on Gehenna are incapable of drawing inhabitants from off plane, as Gehenna is somewhat separated from other planes due to its inner nature. Further, the summoner must pass a DC 15 Spellcraft check to rigorously define the terms of the summoning spell or allow the summoned creature to have total free will.
Divination	Gehenna, being the plane of the apocalypse, in a sense has no future. Thus, any divinations which intend to read events yet to come require the stealing of the future of another; a casting of the entrails of an intelligent being following their death. Divination spells which merely offer detection can be cast freely.
Enchantment	Impeded
Evocation	Enhanced
Illusion	No change
Necromancy	Spells to harm: enhanced; spells to heal: impeded
Transmutation	No change
Elemental	Due to the large amount of elemental material dumped from the Prime, many elemental spells function in differing ways in Gehenna. Earth spells are enhanced throughout the plane. Fire spells are enhanced in the first three layers, and impeded in Krangath. Water is impeded below Khalas, and Air is unaffected throughout the plane.

Spell Keys

Spell keys in Gehenna tend to relate symbolically to the school they represent; for example, the current spell key for Fire is a piece of still-warm obsidian. However, these keys tend to change over time, as the shifting fragments alter the thaumatic matrix of the plane; in general, any given key is valid for only one to three years. Occasionally an invalidated key will still function in the lower layers, but this is spotty at best.
