"and even visited http://www.uesp.net/wiki/Lore:Sheogorath's realm of insanity to battle the Daedric prince and end an eons-long cycle of order and chaos, becoming the new Sheogorath, Prince of Madness." -UESP
Now I'm officially confused. What happens here? Does the hero in Oblivion actually kill Sheogorath and replace him, or merge with his oversoul or something? And if so, if the Sheogorath we see in Skyrim Sheogorath, or the hero from oblivion?
