Prime-Material Plane

The  Prime-Material Plane,  or simply the Universe, is the inner sphere reality in which Djorig finds itself, along with its sun and solar system. It is an seemingly endless void with collections of Stars birthed by Lumeth in the Age of Divinity and sometimes terrestrial bodies that occasionally, even rarer still, hold mortal life.

History
The Prime-Material Plane was created originally by the Core Gods as a prison for the Primordial being, Primordas, to separate it from the Elemental Planes from which it gained strength. It is mirrored by the Faewild and the Shadowfell and surrounded by the Elemental Planes. This collective Inner Sphere stands closest to the Arcane Weave and the Boneyards of Purgatory while the Positive-Energy Plane and its mirrored Negative-Energy Plane both stand at the Inner Sphere's poles.

Metaphysics
The Prime-Material Plane is governed by fixed, if magically mutable, laws of physics such as gravity and a fixed speed of light.

Relation to other planes
The Prime-Material Plane is metaphysically conterminous with the Faewild and the Shadowland, existing in slightly unaligned  dimensions within the same coordinates of the overarching cosmos, with the Ethereal Plane keeping them separate, acting as a transitive plane. The Faewild is pulled from the anchoring of the Prime-Material Plane by its relation to the Arcane Weave, while the Shadowfell is likewise pulled by the Negative-Energy Plane. The Prime-Material Plane is anchored by the Positive-Energy Plane.

Creation Myth
While there is some dispute between the Mortal races as to who exactly created the Prime-Material Plane, there is a general acceptance that it was during the Age of Creation and a product of the War of Divinity. Through limited communication with elementals, they claim that it was not the work of the Gods but of their progenitor Primordas who created the Prime-Material Realm as a refuge from the younger gods and there It rests until time time the four elemental planes are brought back together.
