AARGH! I think this game has a bug. I found the merchant lying in front of the caves after his card to get through the merchant pass was stolen. (A woman in Thais told me he'd be there) I went in, easily killed the four or so total rogues there were, rummaged through the corpses and nada. No pass. I've gone back in and out, re-checked every nook and cranny to see if I missed a room, still nada. I saw the door with the card reader, and could see a couple rooms with thieves that I couldn't access, but nothing else. I'm ready to cry...
