Cosmology - The Great Beyond

The Great Beyond is a term that encompasses all the planes of existence that make up the known multiverse. These realities beyond our reality are the domains of the gods, and play home to non-godly powers fit for worship, planar dragons, and entirely alien races.

There are nineteen major planes that comprise the Great Beyond, modeled as two spheres: the Inner Sphere and the Outer Sphere. Connecting the two spheres is the Astral Plane. The spaces between the primary nineteen 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.
