The Plane of Shadow is a plane of existence that pervades the Material Plane. It is a world of black and white, as though color itself has been bleached from the environment. The Plane of Shadow may be accessed and manipulated from the Material Plane through shadows. Spells cast with the Shadow Weave make use of the substance of this plane in their casting. Since some creatures use the Plane of Shadow to travel from place to place, it is often described as a transitive plane (like the Astral Plane and Ethereal Plane).
