I went High Elf also, I agree that they don't really fit the setting though. Personally I've fluffed it that my character had found a way to magically trap the souls of dragons within himself, hoping for a power boost but instead turning into something of an artificial dragonborn. He would either be a covert agent of the Thalmor attempting to incite Skyrim into war to weaken the empire with his status as something of a folk hero, or a disgrunted exiled mage who wants to see the Thalmor burn. My other character is an Imperial who wants to rally up Skyrim for war to defeat the empire, as it's the only way to drive the High Elves out and restore his home. He thinks being the Dragonborn is a sign from the gods that his path is right.
