Sheogorath
"Daedra are the embodiment of change. Change and permanency. I'm no different, except in the ways that I am."
I've declared Pawanallpa my playground for now. If I've chosen you, little mortal, as my playmate you may run, fight, or die. You may of course, submit, and become one of my subjects that must pay tribute to the cause. If you're too inactive to fight back, you're welcome. I'm picking up the trash you left in everyone's way. After all, why would you care where your cities are if you don't do anything with them? Scenery?
Allow me to preemptively thank you for the fun I will have with you dear mortals. Do try and fight back, I hate it when something dies quietly.
"A change is coming. Everything changes. Even Daedric Princes. Especially Daedric Princes."
Sheogorath owes his origin to his fellow Daedric Princes, for he was formerly Jyggalag, the Daedric Prince of Order. In times beyond memory, Jyggalag had vastly grown in power, and his influence spread across the seas of Oblivion. The other Daedric princes grew jealous and fearful and cursed Jyggalag to live as Sheogorath, the incarnation of the thing he hated most. The curse did allow Jyggalag to return in his true form at the end of every Era, and reconquer his lands, an event known as the Greymarch. After that, however, he would be transformed back into Sheogorath, and Sheogorath would spread madness upon his lands once more.
Sheogorath is one of the first four Daedric Princes mentioned in written history, they say he is the "Sithis-shaped hole" of the world brought into being when Lorkhan's divine spark was removed. One superstition is to avoid thunderstorms, for they belong to Sheogorath. Another is that madmen are driven to that state by speaking with Sheogorath, who gives them advice and information which is beyond their capacity to know. History is littered with stories of worshippers of Sheogorath doing great harm to themselves and others, as well as mortals succumbing to madness thanks to his efforts and those of other daedra. Such people are said to be "touched by Sheogorath", or "Sheogorath-kissed".
Sheogorath is, above all, unpredictable. He is the type of deity that does things on a whim to quench his boredom, such as indulging in a sadistic pleasure and treating everyone as a plaything. A great number of myths, stories, and legends notably reflect this. Sheogorath's favorite passtime is torture, and Sheogorath himself claims to have spent his first three to four thousand years of existence tormenting butterflies, before eventually growing out of it. Butterflies are now associated with him, serving as a sign of his influence. New Sheoth, the divided capital of the Shivering Isles, is said to have been founded at his whim. Myths of Sheogorath is an anthology of tales that serves as another example: "Sheogorath Invents Music" (from the body parts of a young woman), "Sheogorath and King Lyandir" (who was killed by his deranged son after his entire kingdom fell to madness), and "The Contest of Wills" (which Sheogorath wins without even trying). Fall of Vitharn tells the tale of a Count in the Shivering Isles who disrespected Sheogorath, and who Sheogorath rewarded with an overabundance of madness in his family, leading to their demise. While his fellow Daedric Princes feared Jyggalag's raw power, they must fear Sheogorath's cunning. Accords of Madness are stories of Sheogorath's encounters and inevitable triumphs over other Daedric Princes, such as besting Hircine in a duel of champion beasts (by letting Hircine's beast maul itself to death), winning a wager with Vaermina (by doing nothing), and claiming the soul of an Orc who had murdered one of his followers (by letting Malacath do the work and kill the Orc, who turned out to be Malacath's own son). The general theme is that he lets his opponents defeat themselves, remaining impervious and yet doing relatively little unless he's in a bout of (often violent) creativity. Sheogorath has also sentenced a man to death for the crime of trying to grow a beard.
A sudden spark of light shined through the planes between all and connected two worlds during Mid Year, an imbalance in nature called upon a change. Since the Heart Of Corruption fails to embody every aspect of chaos, and The New Light choose not to take on the responsibility of maintaining order, an imbalance in the very fabric of reality caused a reaction. The influence of Daedra slipped through the veil into the wrealm of Illyriad. A mortal was inhabited by the essence of Sheogorath, and that vessel works to rebuild The Shivering Isles on the same plane as the mortals of Illyriad. A world marred by lack of order, yet in peace for lack of chaos. Surely Sheogorath will encounter his alternate self here, Jyggalag, fighting to establish order in the lands.
