TES: Sheogorath's Quest ch. 1

The Hero of Kvatch sat on his—no, Sheogorath's—throne. Sheogorath had made him the new Mad God,  but… it wasn't right.  Not only had he left his old life completely behind, but he also knew that he could never truly take Sheogorath's place. He was in a sort of limbo, unable to resume his old life, but unable to be the kind of beloved ruler Sheogorath was.
"Haskill…"
"Yes, my lord?"
"Do you… miss Sheogorath?"
"… Yes," he admitted, "Yes I do. When you serve a man like him for ten thousand years, he grows on you. But at least there will be no more Greymarches. That was what he wanted…  Wherever he is now, he knows his kingdom is safe. Probably sealed away in the back of Jyggalag's mind somewhere…"
His butler's attempts to cheer him up had no effect. The hero stared at his—no, Sheogorath's—cane, the Wabbajack, the only thing left to testify that the true Sheogorath had even existed.
Suddenly, the entire palace began to shake violently. Both Haskill and the new Mad God looked around wildly. Thunder roared outside, and, with a flash of lightning, as suddenly as it had started, it stopped.
"Wh-what was—"
"No idea," said Haskill, "This doesn't usually—"
CRASH!
A huge, grey, armored behemoth kicked in the double doors and in rushed dozens of grey knights.
"J-Jyggalag? What are you—"
"Silence, servant. I have no quarrel with you. Stand aside."
Haskill, realizing why Jyggalag had come, stood defiantly between his employer and the massive Prince of Order.
"You will not harm him,"  said Haskill.
"Then you leave me no choice."
Jyggalag snapped his fingers, and Haskill screamed in pain and dropped where he stood. The Hero of Kvatch stared in horror at Haskill's inert form.
"He's unconscious, Hero, not dead. I want him to live to serve me. Now… hand over the Wabbajack. Originally, it was known as the Hand of Order. I intend to return it to  its true state."
Jyggalag produced a glowing, jade-green orb. The Hero of Kvatch had only read of this object in books. It was the Sealbreaker, said to be able to unlock anything.
"Give me the Hand of Order."
"No."
"Give. Me. The Hand. Of Order."
"No."
Behind him, a knight brought the pommel of his sword down on the hero's head. He collapsed, stars dancing before his eyes, and the Wabbajack rolled across the floor and came to rest at Jyggalag's feet. The Prince of Order picked up the cane, and activated the Sealbreaker.
There was a flash of green light and Jyggalag screamed as a portal opened on his forehead and a man was thrown from it. His jacket was purple on one side and orange on the other. His hair and beard were grey, and his eyes were catlike. It was Sheogorath.
"Haha! Freedom!"
Jyggalag was stunned.
"How… How did you…"
Sheogorath picked himself up off the floor and dusted himself off.
"Weeeeeeell, I s'pose yer little Sealbreaker there breaks all seals, not just the ones ye want it to."
Sheogorath grinned, but the smile vanished when he saw Haskill.
"Haskill…"
He whirled to face Jyggalag, rage blazing in his eyes.
"What've ye done to Haskill?!"
The Hero of Kvatch, whose vision was returning,  had never seen Sheogorath this angry.
"He refused to cooperate."
This infuriated the resurrected Mad God further, and he lunged at his counterpart. Jyggalag raised the Hand of Order and blasted Sheogorath in midair, sending him flying across the  room and slamming him into the wall. The Mad God scrambled to his feet.
"Ye've hurt Haskill, ye've corrupted the Wabbajack, ye've invaded my realm… what're ye plannin' to do?!"
Jyggalag gave a sinister smile.

"Nothing less than destroying the forces of chaos and evil once and for all. I shall cleanse the world of wickedness, and then, only then, shall my mission be complete."
He pointed the Hand of Order at Sheogorath. The staff glowed, and Sheogorath screamed in agony. His eyes lost their catlike qualities and their luminescence, and his clothes turned a dull grey. He was having his power drained. Finally, the Hand of Order stopped glowing. Sheogorath tried to stand, only to slump back to the floor.
Sheogorath could only watch, too exhausted to act, as his champion, the hero of Kvatch, was run through with Jyggalag's blade and killed. Jyggalag's knights were released into the  Shivering Isles in another  Greymarch. With his last fading flickers of consciousness, Sheogorath vowed to set things wrong again. And with that, the Mad God blacked out completely.
Jyggalag snapped his fingers, and a portal opened. He didn't know where it led, and didn't care. He kicked his alter-ego's prone body through the portal. Sheogorath would hopefully die in the wilderness, and Jyggalag would be left to conquer unhindered.
Jyggalag smiled.
Let the Greatest Greymarch begin.
