The Planes of Oblivion are the dimensional planes which are home to all the daedra. Each of these planes can be very extensive; Molag Bal's plane is described as being a replica of all of Nirn, and Hermaeus Mora's is infinite in size.
Each prince's plane may have a more specific name, for example: Apocrypha for Hermaeus Mora's, Coldharbour for Molag Bal's, Moonshadow for Azura's, Quagmire for Vaermina's. Each plane is supposedly very different in appearance, depending upon the nature of the prince who rules it. They can range from beautiful to desolate; some may not even resemble worlds as we think of them, containing nothing but dust and smoke, or changing constantly.
Oblivion is often associated with tales of Hellspawn and most forms of Destruction (especially fire), and is likely known as Hell, or the home to demons. This image is only accurate for the planes of Daedric princes known for destruction, such as Mehrunes Dagon and Molag Bal, as the Daedra are not actually demons, only sentient beings who do the bidding (often destructive) of their respective masters.For more information, see the Lore article on the Planes of Oblivion.
 Political Views
In the Game, the political structure of Oblivion is as follows:
 Allies & Enemies Affiliations
- In Daggerfall Sheogorath is not associated with Oblivion in any way, he is actual an independent faction and has also no allies or enemies.
- In Daggerfall the Night Mother and the Dark Brotherhood are associates of Mephala. So reputation gain/loss with Oblivion or Mephala influences the factions of the Dark Brotherhood, but not the Night Mother, as well.
