In the generations since the fall of the Akaviri Potentates, a new martial tradition has arisen in Tamriel, one which bears all the hallmarks of a coherent magical discipline, though it is said to be descended from the powers of the legendary Dragons and those mortals who fought them. I refer, of course, to the so-called "Dragon Knights."
Whether or not their abilities originated from Dragons — and you must give me leave to doubt it, for no Dragons have been seen in Tamriel for thousands of years, if they ever existed at all — the powers which a skilled Dragon Knight can deploy are undeniable. There are several right here in the Imperial City, members of the Tower Guard, and they have demonstrated some of their effects at my request.
One of these Dragon Knights, a sergeant in the Guard, showed me how he could wreathe himself in flame without being burned (though I could feel the heat from several paces away). He then cast a loop of flaming chain around a target dummy and drew it too him, where it was quickly immolated. Finally, one of his subordinates burned another target dummy by literally breathing fire upon it!
I was impressed. It was almost enough to make one believe in Dragons.
