The climb up is longer and harder than the climb down but eventually Kalath reaches the top. Going back east through the tunnels of the sewer, he passes the secret door, still hanging open and then the painted frog and arrow across from the southern tunnel.
As he heads east, rats once again can be seen. However, not long after the south tunnel, Kalath spots another painting on the tunnel wall, this time on the south end. It is the picture of a red rat.
