With nothing more of interest in the rat lair, the party continues to move on down the the tunnel. Nothing eventful takes place for the next hour. Soon the path comes to an abrupt halt as the floor of the tunnel drops in a shear cliff about 20 feet as a stream of trickling water over time has cut out a this channel. To counter this, travelers of this route have placed a large wooden plank across the channel which is about 30 feet across. The plank is more or less a thick log and look sturdy, but contain patches of mold, which don't look as if it would lessen the strength of the wood, but instead make them silppery.
