I was wondering if there was any way to create a thrall out of a powerful dremora. I've never encountered one with one of my high characters after about level 15, but do they level up to Dremora Lords? I know you're guaranteed to encounter a few in Mehrune's daedric quest, and if they level, is it conceivable that you could have a permanent dremora lord follower as a thrall? Thanks for your input.
