Shadow Plane

The Shadow Plane is a dark reflection of the Material Plane that overlaps and distorts the world of matter.

While on the Shadow Plane, one can move faster from location to location, as the plane's space is warped and bendable. Each location in the material world has a parallel location in the Shadow Plane, though it is a strange funhouse mirror reflection of that true place. It is relatively easy for a person on the Shadow Plane to see into the material plane and spy on the goings on in reality, and if one knows the right magic to hop out into the material version of the space they inhabit.

Human denizens of the Shadow Plane and their descendants are known as Shadowfolk, and are infected by the immaterial substance of the plane much like those humans connected to the elemental planes.
