Anomalous Planes

The cosmology includes some planes whose exact nature is not clear. These include the Far Realm, the Plane of Dreams, the Plane of Mirrors, and other mortal worlds. Anomalous planes stretch the boundaries of an already fantastic cosmology. They are the weirdest of the weird. They are conceived of as beyond the normal cosmology of planes (even more “outside” than demiplanes), being created from the dreams of all mortals, existing on the other side of mirrors, or built on other mind-straining concepts. Adventures rarely present themselves in these locations, as anomalous planes are genuinely inhospitable to most outsiders. However, denizens of anomalous planes often find their way into the world.
