Rea

Rea is all of Reality. It is comprised of the four major planes, from which all others are derived.

Aetherium, the Supernatural Realms
All things that exist beyond mortal comprehension do so in this plane. Any divine being or individual who has attained great spiritual power

Limbo
Limbo is the realm of demons, and was once the plane of the Goddess before the demons began to appear.

Paradisium
The classical interpretation of heaven most closely resembles this divine realm.

Regna Divinus
Other divine realms are theorized to exist for the remaining divine beings. However as the other gods left Sol long ago, nothing is known of their nature.

Universum, the Material Universe
All things in the physical universe exist here. You Are Here.

Cognitum, the Domicile of the Mind
Cognition has an impact on Rea itself much like the other planes. How one's cognition impacts the world has a change to their interpretation of reality.

In addition, Places such as the Crimson Room and other palaces exist within the construct of the mind.

Aeternum, the Fullness of Time
Forever is a concept that does not even begin to describe this plane. Mortal spirits that have passed into the afterlife will find it here as well.
