When a regular axe just won't cut it.
The teaser image for the Dragonborn DLC is that of a new, Dragonborn Dragon Priest. This is all of the information we have been given so far, but I will venture to say that he is a Snow Elf.
This may seem counterintuitive, considering that nords were the only known followers of the dragons, but it is not too farfetched to assume that a small group of Snow Elves could have picked up the Dragon Cult, especially considering that they lived in Skyrim alongside the dragons and Nords at the time. Also consider that the mask that the Dragonborn is wearing; if viewed alongside a Falmer helmet, the similarity is obvious.
