Along with the official Knights of the Nine and Shivering Isles expansions, a large number of user-created addons and mods are also available for the PC version. Gameplay takes place on both the mortal world, or Mundus, as well as in the many planes of Oblivion as players fight to bring the heir to the throne into power and banish the evil that threatens Tamriel.
