As you get ready to leave the room, Gareth remarks, "Isn't it strange that the leader doesn't seem to have a lot of treasure? Knowing the goblinkin, they would have stashed away *something*. But we hardly found anything in those rooms... Ah well."
You head west and then north, looking forward to breathing fresh air again. However, halfway through the hall, the floor drops out and the first six players tumble down a long, curving slide, leaving Kurik and Gareth, the last two characters, still back up on top.
Everyone else drops down (taking some minor damage) into a 30' hexagonal room with a wooden door on each side.
