The Elder Scrolls IV: Shivering Isles

The Elder Scrolls IV: Shivering Isles is the second expansion pack for the role-playing video game The Elder Scrolls IV: Oblivion.

Shivering Isles takes place on the eponymous isles ruled by the Daedric Prince of Madness, Sheogorath. The player becomes Sheogorath's protégé, and together they try to defeat the Daedric Lord of Order, Jyggalag, thus preventing the isles from being destroyed; this main quest can be ignored for as long as the player wishes to interact with the new world.
