The Transitory Planes

The Transitory Planes are planes which lie in some sense between other planes. While many planes overlap with others in certain areas or occasions, the transitory planes connect to all planes, without being entirely planes of their own.

The Astral Plane is sometimes referred to as the space between planes, above planes, or around planes, while the Shadowfell is within or below planes. Some have poetically described the Shadowfell as the shadow the other planes cast in the light of the Astral Plane.
