Ched Nasad

Ched Nasad is a drow city in the Forgotten Realms fantasy world.

WARNING: PLOT SPOILERS AHEAD!
The City of Shimmering Webs, Ched Nasad, was constructed in a cavern shaped like a cone with the tip pointing downards. The various levels and the more influential buildings in the city are made out of extra thick spiderweb strands, thus giving the city it's name. It was not featured prominently in the Realms until the War of the Spider Queen series, where duergar mercenaries inadverdantly destroyed it through copious use of stonefire bombs, which were much more effective on the webs that held it together than on stone. Out of the 30,000 drow who made up the city's population, around 3,000 survived the disaster.
