The vast nothingness of the Void is a merciless, lightless expanse of manifest destruction and nihilism. Sapping and consuming the life force of any living creature exposed to its energies, it corrodes and disintegrates material objects to rubble, then dust, and then nothing at all, yet the Void contains its own form of anti-life. At their densest concentration, the plane's energies aggregate into bizarre, black crystalline snowflake structures. These irregularities spontaneously generate the plane's resident sceaduinars. Dwelling in exquisitely lethal cities drifting in the vacuous darkness, these so-called void raptors are incapable of true creation and blame this flaw on some ancient betrayal by their rivals in Creation's Forge. Sceaduinars react violently not only toward creatures sustained by
vitality energy, but also toward undead, whom they view as unnatural parasites unworthy of their plane's energies.
The deepest depths of the plane house the most resilient of undead creatures, which survive the constant entropy by virtue of their unliving state. Perhaps one of the most hazardous regions in the Great Beyond, the plane remains in a state of constant entropic advance that technology has yet to overcome. Some brave (or foolish) explorers make their way into the Void, whether to research or hide away from greater threats. Scores of Corpse Fleet agents fled here from the Universe, establishing great shipyards in the plane's most barren realms. The Degradation Swarm, a sentient swarm of self-replicating entropic nanites, meanders through the plane like a roiling thundercloud that converts everything in its path, with some of its tendrils being summoned into other planes of existence.
