Jyggalag

Jyggalag is the Daedric Prince Of Order. He was at one time a powerful Prince, so powerful, however, that the other Princes began to fear his Power and cursed him to live in opposition of everything he stands for, cursing him to live the life of a madman. Sheogorath to be exact. He was transformed into the now Daedric Prince of Madness. However he was allowed his original form once after every era, an event known in the Shivering Isles (Sheogoraths Realm) as the Greymarch, when Jyggalag exerts his control over "his" realm to summon the Knights of Order, his emotionless, viscious minions, to attck and burn everything to the ground. Near the end of the Greymarch, Sheogorath would "leave" the Isles and Jyggalag would come in person to finish the Isles off. In reality, Sheogorath simply transformes into Jyggalag. Sheogorath then "returns" to recreate the Isles and its inhabitants, causing him some suffering.

However, after the death of Uriel Septim VIII, the Greymarch begins once again. This time however, Sheogorath send an "invitation" of sorts to mundus in the form of a strange door. The Champion of Cyrodiil went through and met with Sheogorath, who appointed him his champion. Through the Champion's actions, Jyggalag's plans were somewhat diverted. Jyggalag was forced to confront the CHampion one-on-one, and was defeated by the Champion. After his defeate, Jyggalag disclosed his story to the Champion and named hm the new Prince of Madness.
