Editing Planes of Existence (section)

=== Elemental Chaos ===
Generally speaking, the closer the Elemental Plane is to the Material Plane, the more “pure” the plane is. The Plane of Fire, for example, is entirely fire the closer to the Material you get, and more diverse the farther away. The farther away you get from the Material Plane, the more the Elemental Planes begin to break down and commingle with each other, creating at the edge the Elemental Chaos, a strange and formless plane where all of the elements coexist in chaos. In the deepest recesses of the Chaos lie various primordials who were cast away long ago.
