*Spoilers for "Elder Scrolls 4: Oblivion" "Shivering Isles" quest-line*
In the 3rd era, Sheogorath was sick of the Greymarch, he was sick of having to rebuild his kingdom, he was sick of swapping back-and-forth between his amazing self and boring, old Jyggalag. So he decided to try something new, to play a little trick, he decided to leave behind a champion to defend his realm from his other self. No one could possibly have predicted the results, not even if they had bothered to try.
