Cosmology

Dimensions

Dimensions are akin to an entire Universe each one filled with its own Galaxies and Solar Systems. Every campaign setting has their own dimension complete with their own planes.

Astral Rivers

Astral Rivers flow between dimensions normally going from one Astral Sea to another. The dimension of Alamai unfortunately doesn't have an Astral Sea and only possesses Astral Rivers.

Planes

Planes are akin to their own Solar System and each dimension has their own. Each plane is represented by its own constellation.

Layers

Layers of a plane are similar to their own planet in general and are also known as Realms. Some of these layers have moons.
