Can't figure out where I'm supposed to go. The viscount directed me to the gnome prince, who had me killing some drow in the basement, but I'm not sure who I'm supposed to talk to advance the quest. I feel like I misread the dialogue or something, and I don't have a save that isn't a few hours before heading to Verbobonc, so I'm not certain what I'm supposed to do. Google yielded talk of a dragon, but I've no idea where that might be. Help?
