The Planes of Edrazion

The Planes of Edrazion encompass all the planes of existence that make up the known multiverse. These realities beyond our reality are the domains of the gods, non-godly powers fit for worship, planar dragons, extraplanar beings, and entirely alien races.
There are eighteen major planes that comprise the Planes of Edrazion , modeled as two spheres: the Inner Sphere and the Outer Sphere. Connecting the two spheres is the Astral Plane. The spaces between the primary eighteen planes contain countless demiplanes. Despite the names implying a spherical layout, the planes exist on dimensions incomprehensible to mortals, thus these terms are used to represent the planes in two or three dimensions.

Inner Sphere

The Inner Sphere is the center of the planes, sitting at the hub of creation surrounded by the Astral Plane. It is composed of the immensely huge, yet finite layers of the Elemental Chaos, which surround the Universe, which are in turn separated by the Ethereal. At the metaphysical center of these sit the dualistic Faewyld and Fell of Shadows.
