Known Universe

The Planes are dimensions making up the known universe. These planes frequently merge and split off like streams or rivers, with dimensions frequently being created or subsumed into other planes.

Material
The material planes are designated by number, and are the type most commonly associated with Earth. The material planes are similar, however people and events often vary from plane to plane.

Prime
The prime planes are each ruled by a different element or state of being, taking on it's characteristics. These include the Shadow Realm, the Frog Dimension, and the Underworld. The prime planes are not subsumed or merged in the same way the material planes are, however they will still sometimes interact with the material planes or each other in a conjunction event. This leads the conjunct plane to take on characteristics of the prime plane it is nearby, and allows individuals to travel more easily between realms.
