The Plane of Shadows is a plane of existence that pervades the material plane. The Plane of Shadows may be accessed and manipulated from the material plane through shadows. Shadow spells make use of the substance of this plane in their casting. Since some creatures use the Plane of Shadows to travel from place to place, it is often described as a transitive plane (like the Astral Plane and Ethereal Plane).
- The Plane of Shadows was featured in the Shadows of Undrentide campaign.
