The history and details of Nadrun the Artificer, who designed the aptly named Nadrun's Doors for Undermountain, just popped into my head as if it were a memory of something I already knew. I did some searching. Nadrun hasn't really been developed anywhere else that I can find. So...here's a challenge. Who can guess where Nadrun is originally from and where he learned his lethal art (as I'm detailing it in RoUIII)?
