I always find it amazing that people doubt whether Shivering Isles was canon but seldom deny Knights of the Nine. SI was a full blown expansion pack that had its own retail package for PC.

The only possibility that the CoC is not Sheo in Skyrim is that he either died sometime after SI or SI was a ploy by Sheo to drive the CoC insane and into the madhouse. Considering the number of other powers watching over the hero, the latter is highly improbably. I wouldn't discount death though. The Isles does not become a safe place just because everyone smiles at you after you become Sheo. That said, gaining longevity and even immortality in TES and in SI especially is far from impossible.

I like to think the CoC was a great fit for Sheo. Only a champion worthy of the Mad God would undertake deadly quests daily without regularly eating or sleeping.
