Was fighting Karstaag and used all three words of Dragon Aspect. Got the familiar cloaking animation, but something interesting appeared: Ancient Dragonborn! At first I thought he was another adversary, but he was friendly and starting attacking Karstaag! Which was a relief for my archer specced assassin. She just sat back and lobbed arrows until Karstaag went down.
Unfortunately the Ancient Dragonborn hasn't appeared in any of my other fights using Dragon Aspect. Is this a Karstaag only event? I did fight Kaarstag after killing Miraak, so I wonder if it gets added to Dragon Aspect after killing him?
Any explanation greatly appreciated.
