=== The Negative Energy Plane ===
By traveling to the great black orb in the Astral Plane, you'll find yourself in the place where all black holes go. The Shadow Plane may be dark, but this place is different. The Positive Energy Plane is the source of all light and life; this place is the end of it. It's not that there's no light here. Light pours into this place from all of the black holes and from the Astral Plane, but light here fades very quickly. The result is that things in the distance fade from view quickly. In addition to that, the Negative Energy Plane leeches the life out of everything within it. This ebbing life energy causes living things to glow faintly, at least until their life energy runs out.
