Prime Material Plane
The plane most organic beings call home. The Prime Material Plane feeds off the energies of the Transitive and Elemental planes and is the balance point of the multiverse.
Transitive Material Planes
These planes overlap the Material plane like two sides of one coin. Each plane is a concentrated reflection of the forces that shape the Prime.
The Elemental Plane
The elemental plane surrounds the Material planes but rarely overlaps it. Upon first glance, visitors may be lead to believe that the plane is are made of material substances, but this is not the case. Raw elemental energy forms the substance of the plane and flows forth from elemental nodes. The elemental energies constantly jostle against eachother and feed power into the prime material plane where it forms material air, water, stone, fire and all other material substances.
Seat of Eo
The Stygian Marsh of Limbo
The first stop for the souls of every deceased mortal. Limbo is neither punishment nor reward. Most souls left unclaimed by the higher or lower planes drink of the river Lethe and are robbed of the memories of their former lives.
The Silent Realms
The last stop for unclaimed souls weighted by the actions of their uncaring life. These realms are not the eternal suffering of Inferus or the Abyss, but are nonetheless unpleasant.
Home realms of Ashmedai and his devils. This is the final resting place of wicked and heartless souls, the spawning pit of new devils, the bureaucratic center of all diabolic bargains and front line in the war against the Abyss.
The Infinite Abyss
Not a realm in itself, but a cascading infinity of chaotic realms. The forces of the Abyss are endless and can not be truly defeated, but individual layers can be won or lost. Only by the strength of those that oppose them do the demons not simply wash over the finite realms above.
This is the space outside other planes, also known as the space between spaces. It is a timeless realm without air or light. Little more than a buffer zone between the known realms and the Far Realm. Travel through Near Space is difficult as no means of propelling oneself seems effective and magic does not function. That being said, there are demi-planes that exist in this realm, each with their own unique features.
