So...unless I missed it and it was explained somewhere: is the Sheogorath in Skyrim the REAL Sheogorath? Or is it the Champion of Cyrodiil? (I remember either Sheo or the butler telling CoC that they can't become a Daedra...)

Both

I was wondering the same thing as well. Was it Champ of Cryodill or the original Sheogorath.

In Official canon, the Champion of Cyrodiil becomes the new Sheogorath. The old Sheogorath reverted into Jyggalag, and just before that gifts the CoC with all of his might.

I can therefore be safely assumed that the Steward on the Palace is wrong and that with time (apparently 200 years is quite enough time). just having the powers of a Daedric Prince, and performing the duties of a Daedric Prince, the CoC Mantled himself and thus became Sheogorath.

So like a person above me said, the answer is both. The CoC is Sheogorath as in the process of Mantling, the CoC and the very Essence of Sheogorath became indistinguishable over the course of those 200 years, therefore he ceased to be the CoC and fully took on the Powers, Essence, and Persona of Sheogorath. Thus your old character is now an Immortal Daedric Prince of Madness and Creativity.

Given the COC is making Pelagius the Mad SANE as opposed to mad, it's also quite possible that he's running a shell game.

I.e. acting like the original Sheogorath while pursuing his own agenda.

I don't agree with that as official Canon.

Who says you need to be a Daedra to be a daedric prince? Daedra simply means "not of our ancestors" no matter what power the CoC gains he will alway be descendant from the Aedra and thus technically not a daedra. But I wouldn't argue that point with him. Not unless I had a parachute on,.

Well, Daedra are the embodiment of change. Change and permanency.
So, I think he is the CoC. Except when hes not.

So I guess that settles the argument. CoC is the most powerful antagonist(right word?)

i want to do sheogoraths shrine ... what level is recomended tahst all i want to know ill find it on teh game banshee map if its listed

Is that an opinion based on fact, or a refusal to accept the established metaphysics of the TES universe, that is both documented heavily before Oblivion, and foreshadoweded strongly throughout Shivering Isles?

If you played Shivering Isles with both eyes open you'd have seen this coming

You can do it at any level, but don't waste time looking for a shrine; there isn't one. Hang around near the bard's college in Solitude and the quest'll come to you.

Even though CoC is Sheogorath now (I think everyone's decided that...so I'll go with that), I don't think they're more powerful than the Nerevarine. (I read somewhere that the Nerevarine achieved CHIM.)

I didn't agree with how he pronounced his name. Shay-O-Go-Rath.
I always thought it was a blur you just spit out, like Sugar-Rath.

Well, maybe you'll come across a voice actor that'll pronounce it that way! Sometimes they can't decide (similar to 'Dwemer'.)

Source? I thought only Vivec achieved CHIM.

Posters on Gamefaqs. They said Vivec and Tiber Septim definitely achieved it and that it's speculated that the Nerevarine did too.

Although they also said...negative things about the entire concept.

Problem is that Daedric Princes are full power gods that have all of their power while Aedra gave up some of their power to create the world. So Daedric Princes > Aedra seeing as how the main god Akatosh was only able to put Mehurnes back in his realm, not kill him despite Akatosh being the MAIN god of the ES Pantheon. So the CoC is a Daedric Prince and thus more powerful than Aedra

Sheogorath isn't actually a person. He is more like identity, personality and madness which takes over the person who has been considered to be Sheogorath. It's not important who he was before because now he is Sheogorath. You can compare it to the identity and crowl of Gray Fox which makes it's carrier to be Gray Fox.

If the Nerevarine achieved CHIM, she would be far more powerful than any Gods or Deities.
