The source cited is merely a list of known drow cities; it has nothing beyond the name of the city. None of the material in this article is substantiated by a source, other than "According to the CRPG..."

Please put the Icewind Dale game in the source listing, if in fact it is a source, and then cite the details in the article that come from the game. I don't have the game, so I can't verify it myself.
