The Elemental Planes surround and enfold the Material Plane and its echoes, providing the raw elemental substance from which the world is made. The four Elemental Planes- Air, Earth, Fire, and Water- form a ring around the Material Plane, suspended within a churning realm known as the Elemental Chaos. At their innermost edges, where they are closest to the Material Plane (in a conceptual if not a literal geographical sense), the four Elemental Planes resemble places in the Material Plane. The four elements mingle together as they do in the Material Plane, forming land, sea, and sky. As they extend farther from the Material Plane, the Elemental Planes become increasingly alien and hostile. Here, in the outermost regions, the elements exist in their purest form: great expanses of solid earth, blazing fire, crystal-clear water, and unsullied air. Only pure elemental creatures can survive on these outer edges where the Elemental Planes devolve and mix into the swirling Elemental Chaos.
