Taklinn, you listen at the stream as it flows eastwards. You are waiting for action on the rope when the trap door swings back upwards, closing the hole up and trapping the rope in the seam.
Thoart, you enter the lair again. Nothing about the scent seems any different. You notice the snakes at the north of the entrance again, but they do not make any moves toward you. You keep pressing in, and pass into the dragon's lair. Through the open doors, you can see Taklinn and Davik peering anxiously at the ground, holding a rope.
