Penumbral Plane

The Penumbral Plane has sometimes been called the Prime Plane's shadow, and this belief is thought to be where the Penumbral Plane derives its name, though this view is somewhat inaccurate. In actuality, the Penumbral Plane is thought to be a "shadow plane" for all other planes in existence. It is layered upon itself, acting as a transitive plane for things such as shadow walking spells, and entering into the Penumbral Plane from one plane will bring the caster to the penumbra of that particular plane. It is thought to be impossible to enter into a plane's penumbra without being on that plane to begin with. A plane's penumbra tends to shift and change just as an eclipse's shadow changes depending on the location of the celestial bodies creating the eclipse. As such, it is not always possible to enter into a plane's penumbra and end up in the same geographic location as where one started, and spells may bring would-be travellers to different parts of the Penumbral Plane than intended.
Mimicries of living creatures in other planes are often found in the Penumbral Plane; before planar theory was widely understood, some mistook the Penumbral Plane for the world of the dead, for the shades in the Penumbral Plane tend to outlive their counterparts in other planes.
