Planar Regions

The Universe teems with an unknown amount of worlds as well as multiple alternate dimensions of reality, called the Planar Regions (or planes of existence). There are pocket dimensions/planes in existence within the planes some large in size others so small they go unnoticed.

Beyond the physical planes are realms of pure thought and ethos, the homes of fiends and celestials, and the dominions of gods and the domains of raw elemental matter and energy that are the foundation of the universe.

Physical Planes
The Physical Plane is where the philosophical and elemental forces that define the other planes collide creating an existence of mortal life and mundane matter. The rest of the universe is defined in relation to the Physical Planes. Originally the Physical planes were a singular Plane that was in constant chaotic change, the Primal Gods of the universe seeking for life to exists balanced the universe by separating the physical planes so that one material plane could flourish with balance this started a chain reaction across the physical universe cementing the balance throughout.

 * The Wilds
 * The Abyss

Inner Planes
The Inner Planes surround and enfold the Material Plane and its echoes (The Wilds and The Abyss), providing the raw elemental substance from which all the worlds were made. The four Elemental Planes of Air, Earth, Fire, Water, void and Light form a ring around the Material Plane, suspended within the churning Cosmic Chaos.

At their innermost edges, where they are closest to the Material Plane the six Elemental Planes resemble a world in the Material Plane. The six elements mingle together as they do in the Material Plane, forming land, sea, and sky. Farther from the Material Plane, though, the Elemental Planes are both alien and Hostile. Here, the elements exist in their purest form
 * Plane of Fire
 * Plane of Water
 * Plane of Earth
 * Plane of Air
 * The Void
 * The Light
 * The Ethereal plane
 * The Astral Plane

Outer Planes
The Outer Planes are the direction, thought and purpose for such construction. Accordingly, to many the Outer Planes are known as divine planes, spiritual planes, or godly planes, for the Outer Planes are best known as the homes of deities, celestials and fiends.
 * Anuris (the heavens, the shade lands, afterlife)
 * Gehenna (hell, underworld,the grave)

Demiplanes
Demiplanes are small extra-dimensional spaces with their own unique rules. They are pieces of reality that don’t seem to fit anywhere else. Demiplanes come into being by a variety of means. Some are created by Spells, such as  Demiplane, or generated at the desire of a powerful deity or other force. They may exist naturally, as a fold of existing reality that has been pinched off from the rest of the multiverse, or as a baby universe growing in power.
