Oblivion (Eurasian: Oblivio; Dovazhul: Oblivion) also called the Void of Oblivion, the Planes of Oblivion, and Wastes of Oblivion, is a collective term used to describe one subset of the planes of existence. The planes of Oblivion are those that have the least connection with the mortal plane, Mundus. Oblivion is also home to the Daedric Princes.
The planes that make up Oblivion are defined primarily by exclusion. Any plane which is not Nirn itself, not one of the planets or moons, and not Aetherius itself, is generally considered to be a plane of Oblivion. It is commonly believed that there are an infinite number of such planes, though Deosian scholars are aware of only a small handful. In particular, it is believed that each of the sixteen Daedric Princes rules over his or her own plane, which is formed into an image of his or her choosing indicating that there may or may not be just sixteen planes in Oblivion.
