I'm not one of these players that are obsessed with ingame power (lol, I won't make any jokes...) but there's one thing that's in fantasy medieval movies, and that's the duel.

By duel, I mean I want to face an enemy in which we would both batter each other for a few minutes, and it would be a BIG challenge to beat. I would want to fight a humanoid enemy (dragons are fun, but not the man v man medieval duel I'm after) where we both fight with swords.

So... what enemies can I find like this? I've heard of the Ebony Warrior, but I don't yet have Dragonborn. And I'm on the XBOX.

Definitely

And who is this? Where can I find him?

He's also added by Dragonborn.
