Dragons, there's precedence for a hero emperor in TES. First, there's Tiber Septim who kicked butt all over Tamriel. More recently, Martin Septim strapped on a suit of armor to fight his way through the Daedric Forces of Destruction in the Imperial City and then turned into the avatar of Akatosh to do battle with Mehrunes Dagon.

Plus, there's even precedence of a Hero type becoming a ruler. The Champion of Cyrodil (AKA Hero of Kvatch) became the Madgod Sheogorath. Looked like Haskill ended up in charge of the bureaucratic side of the governing while the new Madgod just had to save some villages from random creature attacks.
