The Plane of Shadows

The Plane of Shadows (Shadow Realm) is another plane of existence in C. A. Perez's books. It is typically depicted as empty, cold, and dark. The natural state of the plane is a black aether only broken by some deep purple anomalies and the Swirling Void above. The Swirling Void is a multicolored spiral that has not yet been explained by observers. It seems that nothing is there, and that is supposedly how it received its name.

The denizens of the Plane of Shadows are just shadows and shades. Many see a semblance to creatures of other planes so it is theorized that every being makes a shadow in this plane, sometimes in addition to a spirit that eventually reaches another plane of existence. Most of the time, the shadows are chaotic in nature, and will react in a number of ways to intruders of their realm. Most often these beings observe, and if they attack they do so without regard for their existence.

If one sets foot on the plane, it is assumed that being is immediately under scrutiny or has been sensed by the plane and its inhabitants. Many do not stay on the plane very long because of this, for all the shadows begin to converge upon the intruder.

It has not been confirmed that "slaying" a shadow completely removes it from existence, unless its essence has been consumed or removed by other means.
