It has come to my attention that Sheogorath himself may have been responsible for the return of the Greymarch, other than the fact that his is Jyggalag. He sends the CoC to reactivate Xedillian, an ancient structure that calls to the minds of 'unwanted' mortals.
The Champion of Cyrodiil lays curled up in a ball in the corner. He is rambling on to himself "I am Sheogorath, I am Sheogorath." Sheogorath looks over at the Champion of Cyrodiil and laughs.

See, doesn't that give you more of a giddy, excited, satisfied feeling?

What's scarier: to wake up as someone you're not, or to wake up as someone you used to be? What's the difference?

He would have to be insane to become seogorath, because Seogorath is insanity. Mehrunes Dagon desroys things because he is destruction, so to become Mehrunes Dagon you would have to destroy things. get it?

I hate the whole, "Seogorath just drove the Coc insane and the Coc made it up" theory, given that after becoming sheogorath you can go back to cyrodil and have Jyglyag freeze people. Or get physically over encumbered by only Maddness ore. if you were just imagining it, when you froze somebody i'm sure they'd fight back.

Depends. the CoC is still mortal, so he may have died in the time TES:V is in, thus allowing a new Sheo to take over.

He isn't mortal though. In my opinion, his flesh and his soul became part of Sheogorath's flesh and soul. When you go nuts, you go Coc. and there will always be crazy people.

BUT he is only lord of the Shivering Isle! THere are other lands controlled by Sheo, and they will be ruled by others.

What other lands? it's called Seograth's MadhousE. not Sheogorath's MadhousES

There are only to Daedra with more then one realm. Dagon, he has the wastelands, but also a small island he threw into oblivion. And Meridia, who has the colored Rooms. they are millions of one-room realms, used for preserving the energies that make all life possible.

What I'm also interested in is what is Jyg gonna do with his newly found free time? Will he begin his conquest anew? Or, will he take it easy and let the anticipation set in on his brothers and sisters as they watch to see what he does next?

What exactly did the CoC do that was "insane"/"mad"/"loony" during the SI quests?

I liked the symbols. The symbols were nice and great at showing the transition of power from Sheo to CoC, but you never walked like Sheo. Everything you did was with purpose and order. Doesn't really matter though, if everyone else in Nirn sees the CoC as Sheo he will be Sheo.

And Sanguine, with thousands of realms that serve only as pleasure pockets.
But as the prince is the realm, you can see all those realms owned by one prince as one realm. I suppose there aren't borders or something in-between.

Light yourself on fire? Pursue a series of quests designed to turn you into Madness incarnate, with all the power of Madness flowing through you and in command of the Realm of Madness? Do battle with yourself? Pursue a library that turned out to be a man? I could go on.

Mehrunes has a point. Afterall, after it's all over, you can understand the gibberish-man, change the weather to anything random, freeze time in one area while everything else keeps moving, summon a random dancer to just dance, do anything and not get in trouble for it, and very few people seem to care.

Not to mention that through the process you've also killed a king and queen for being in love with eachother, eaten Feldew to get more Feldew, to get the cure for Feldew, killed a conspirator against a Queen who later gets killed by you, killed the baby of a sad Necromancer who can bring people fully back to life, helped two different races fight, and run around like a mad-man when Sheogorath could have just teleported you everywhere.

I'd say the character pretty-much went insane, or at least did insane things. I don't know about the whole "making it up" thing, because my black finery looks pretty real, and I sold it too.

Not to mention that there's always Order in Craziness, and Always Craziness in Order. There's a reason why Jyggalag didn't just change his realm back through magic, or why Sheogorath devised a plan, not to mention he has Haskill, who is the most Orderly person I know.

There's a reason Craziness and Order were put together and not Craziness and Death.

In a world where I can make fire at the wave of my hand, being lit on fire but not be hurt by it isn't crazy. Oh no, it's a doppleganger, I'll surely turn mad now. The people in Xedillian go crazy for the stupidest reasons.(Save for the orc. His at least was a believable reason). Need I remind you that you start Sheo's quest to be a champion and expecting reward(Heck you do other quests for daedra and get some really nice stuff out of it), not to become the madgod(Even still I think thats some pretty good motivation for quite a few people in Nirn to do it; turning into an immortal god isn't incentive?). Killing the duke and duchess isn't really crazy. You kill plenty of people in the game just because someone told you to do it(Dark Brotherhood?). If any of that crap makes you crazy, then the Nerevarine went off his rocker long ago.

I'll agree with you that you are insane at the end. Just for a different reason.

Fire not damaging you aside, first, what kind of person would willingly light themselves on fire, dedicated monks aside? Second, how would it look to Joe Imperial if you ran past them on the road on fire, and not asking or seeking a way to extinguish them?

No, even with magic, lighting yourself on fire is still a mark that you've got a few screws loose.

But I feel nice and warm. And it's great during a blizzard!

Even with a 100% fire shield eh? Actually I seem to remember a blackwood company man doing this too. Personally if I saw someone on fire that wasn't reacting in pain to it or even being consumed by it, I wouldn't think he's crazy. That's a crazy assumption to make. Maybe blessed by the gods, but not crazy. Crazy people set on fire die. Given the odd color of the fire looks more like some magical aura. Hey whats more is I have record of others doing it and not being hurt too.

Hannibal Traven didn't seem to mind.

Woah, Pelagius! Where's that fire?
