Shivering Isles is the first and only major expansion for Oblivion, and the only major expansion pack for the game. Set within Sheogorath's plane of Oblivion, the Daedric Prince seeks a mortal champion to save the realm from the devastating Greymarch, led by the dreaded Forces of Order. Many mysteries await investigation in this twisted, split reality that the Prince of Madness calls the Shivering Isles.
- Shivering Isles features more than 30 hours of new gameplay and allows you to explore an entirely new plane of Oblivion – the realm of Sheogorath, the Daedric Prince of Madness. Shivering Isles adds to the existing world of Oblivion so you can continue playing with your existing saved game or character, or create an all new character just to explore the new content. —Official Summary
