Diametrically opposed to the Spirit World, the Shadow realm is a bleak dimension cloaked in eternal darkness filled with decay and dread. This dimension was created by the First Gods as an afterlife for the souls of the dead, but once its keeper perished in the Godswar the realm was left alone and forgotten. The Shadow Realm began to take its current form after a mysterious entity known as Shade found the plane and made it their own, crafting a domain of eternal darkness from which they could influence the material plane.
