An airless, featureless void of darkness with gravity being an individual choice. Somewhat paradoxically, a border region allows for structures to exist on a landscape of sorts, either made of the physical, solid darkness, or perhaps of elemental earth that could survive in regions of the plane that did not exhibit the major-negative dominance trait. The atmosphere was not vacuum but could not be used by winged creatures for propulsion, nor could it sustain life, yet torches and lanterns would burn for a short while before being extinguished. Magical light sources worked as usual but visibility was extremely limited. These characteristics led cosmologists to speculate that it was the energy-sucking nature of the plane that greedily devoured any life-giving energies rather than the complete lack thereof, but the difference is of interest only to sages. In practical terms, without protection from the negative energy and elimination of the need to breathe, death was only a few minutes away at best.

Just as there were areas where the negative energy seemed to recede and create the doldrums, some locations exhibited concentrations intense enough to create stable chunks of solid matter that were dubbed voidstone. These absolutely black blobs ranged from a few inches/centimeters in diameter to the size of a small house and perhaps larger. Anything that touched a voidstone was destroyed in the span of a few heartbeats—even the undead were not immune.

No matter where you enter this world from, after three days of travel in any direction except up, you will meet a great void of pure blackness, which is the source of the life draining force of the realm. Passing into this void accelerates the passage of time tenfold, and is complicated to exit at all. As with on the Positive Energy Plane, while in border regions of this plane, one can see into neighboring planes, though those on neighboring planes can not view the traveler without magical assistance.
