Outer Planes

The speculated structure of the planes is divided into four neat packages outside of the mortal realm. This apparent simplicity will deceive the unwary.
Palatium: The celestial palace court. The Heavens.
Astra: The sea of starry light connecting all motes in the skies and beyond.
The Void: The dark astral threads permeating the space between the stars, worlds and planes.
Carceri: Hell, as imagined by the free peoples of the world, is eternal prison.
