Yeah, he should be just attacking. Maybe someone charmed him? Not sure if you're playing with some scripts But it's not exactly a quest, but a chance to get only lightly enchanted katana for low-leveled heroes Well, you can learn where he got this sword from, there is a woman near the mine entrance (exterior area), but it's just that.

But when examining his unidentified sword, the description reads "Why don't you just ask him?"

Erm, that sounds like a bug? I checked and the unidentified item description has a normal katana description, but... well, at least it's a funny bug

Thanks for the note on that typo It's a big mod, there may be some more of these. Thanks for understanding!
