Need info on the Steel Kingdom of Dunspeirrin

[questionmark]

I am looking for detailed information on the city of Dunspeirrin, population, slaves, assets and all that the description in the underdark book is very vague for such a big city, which leads me to believe that a more detailed description is out there.
please help! My players will want to go there soon.

Thanks,

The best place to have your FR questions answered is the forum at www.candlekeep.com.

I think the Steel Kingdom was probably an invention of the ever-creative Eric L Boyd and he posts regularly there.

FWIW, I think that there is also a write-up on 2E's rather good Drizzt Do'urden's Guide to the Underdark and I think that this might also be the only other product in which it saw print (but I can guarantee that someone at Candlekeep will correct me if I am wrong).
