The heroes of Tamriel have always been one of the mortal races(Nord,Imperial,Altmer,Khajit,etc.) but what about some of the intelligent humaniod Daedra - Dremora, Mazken, Aureals, etc.? Game-play-wise there is nothing preventing them from being plausible as they use the same animations as men/mer/beastfolk, so the conflict would be lore/cannon. Would it make sense? Could it be plausible? Would a Daedra do it? The Daedra are highly unknowable. What little we do know is based on inaccuracies, conjecture, rumour, myth. Who are we to conclude that a Daedric being can't fulfill a prophecy pertaining to Nirn? There are ways they could be binded to the mortal realm until physically banished. Conjurer's experiment gone wrong? Daedric Prince's will? Aedric deal with Daedric Prince for one of his servants?
I guess a good way too sum up my question for this discussion is: how far-fetched is it? Daedra have always played a significant part in all TES games. Either as main baddies, Summonable minions, or in Morrowinds case; actual inhabitants to some extent. Would you like to see them as new playable races? Summerset isle is without doubt a magical oriented place. If the next TES took place there I don't see why their inhabitants would be freaked out seeing a Dremora walking down the street. They probably see daedra every day!
