I don't agree with nor support the motion that the COC is indeed Sheogorath. As to what's going to be canon with the Dragonborn, I'd say Warp Of The North will occur or something similar in nature.

Yeah, of course that's the irony. I think with Hammerfall gone, the majority of the Imperial Legions are Nords.

NO WONDER they want to keep it.

History will never remember which side won the rebellion. All they will know is that the old empire fell, and the dragonborn kicked their armies into shape and lead them into the second great war against the dominion reforming a new empire.
