If you have gotten the clue from the slums (the djinni) then go to the Arlax sewer. The entrances look like fire pits and are in the corners of the town, inside the fence. Once in the sewers walk around to the south/southwest and a drow should come up to you and start dialogue to the next clue.
Have fun. It's a great mod.
thank you very much..I was starting to thing I was losing my mind
