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.
In total, 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.
The Inner Sphere is the center of the Great Beyond, sitting at the hub of creation surrounded by the Astral Plane. It is composed of the immensely huge, yet finite layers of the Elemental Planes, which surrounded the Material and Shadow Planes, which are in turn separated by the Ethereal. At the metaphysical center of these sit the dualistic Positive and Negative Energy Planes.

The Astral Plane surrounds the Inner Sphere, and fills the space between all of the planes of the Outer Sphere. The Plane of Fire, outermost of the inner planes, is often shown in maps of the multiverse as being a dot, or burning sphere, floating in the Astral Plane at the center of the Outer Sphere.
While the Inner Sphere contains the elemental planes, the Outer Sphere contains nine planes, each with a strong tie to one of the nine alignments.
