The Planes of The Veiled Realms

The world of Aurora is composed of many realities, called Planes, each with its own rules, composition and inhabitants. There are 3 main categories in which the Planes can be sorted, with the Prime Material as the outlier. The "Inner Planes", the "Outer Planes" and the "Transitive Planes". There is another place, known as the "Dead Realms", which has a presence in this world. It is however the most mysterious and unexplored part of the cosmos.

The Prime Material

The Prime Material plane consisted of an infinite expanse filled with a fluid known as phlogiston, within which floated immense crystal spheres, each enclosing an entire system of one or more worlds. Specific conditions varied greatly from one crystal sphere to another, but they were all considered to be part of the same plane. Aurora was one such world.

The mostly empty space contained inside the crystal spheres, known as wildspace, as well as all the worlds that existed within each sphere, were connected to the border of the Ethereal plane. It was unclear whether the phlogiston was also connected. The Ethereal plane served as a conduit between the Prime and the Inner Planes.

The Prime Material plane was also connected to the Astral Plane, which served as a conduit to the Outer Planes. There was no known direct way to travel between the Inner and the Outer Planes, or between the Astral and the Ethereal, that did not pass through the Material Plane first. Similarly, the Prime was the only plane in which spells that required a connection to the Ethereal or the Astral both worked.

Being the only plane that intersected both the Ethereal and the Astral, the Prime Material plane occupied an important position as a crossroads of the multiverse, and all other planes were defined in relation to the Prime.

Transitive Planes

The Transitive Planes are special in that they are the connection between all planes. Without these, nothing and no one from any Inner or Outer Plane could ever reach or interact with the material plane. These planes can be compared to the emptiness between realms, they are unique in that they only exist as gateways to other planes and do not have their own physical reality. To move within these is often more a mental exercise than a physical one.

Inner Planes

Connected to the Prime through the Ethereal Plane, the Inner Planes contained environments that were among the most hostile in the multiverse. Unlike the Outer Planes, which were built on belief and thought, the Inner Planes were the manifestation of central aspects of physical reality. As a result of this intense concentration of reality, everything in the Inner Planes, including its inhabitants, felt more vivid and intense, while at the same time more indifferent.

Outer Planes

Connected to the Prime through the Astral Plane, the intangible and esoteric Outer Planes—the realms of ideals, philosophies, and gods—stand in contrast to the Inner Planes, which compose the material building blocks of reality and the realms of energy and matter. The Outer Planes are a collection of Planes built upon by belief and the power of potential. They can also be referred to as godly planes, spiritual planes or divine planes. The Outer Planes are home to beings such as deities and their servants such as demons, celestials and devils.

Celestial Dominions

The Dead Realms

The dead realms are a cosmic junk heap, myriad realities that have become unstable or suffered through an irreparable apocalypse and have inturn scoured or abandoned of mortal life and the gods that oversee them. Seeking to avoid further disruption of the cosmos, the great entities which govern the astral sea quarantine the dead realms in their own fold of space. Cross contamination renders the plane into a simmering cauldron of chaotic energies, as civilization plagues and reality storms crash against each other with the tomb-prisons of world eating gods as backdrop. Any breach of the realms’ containment could lead to potential doom, as anything that can survive the end of multiple worlds is likely more than capable of ending a few on its own.
