Below you hangs the rib cage of the dragon, and below that the long drop
towards the chasm floor.  Dragonbone bridge shows no sign of movement,
making you wonder if it would give way even under a buffalo stampede.  The
skeletal walkway continues to the east, and to the west is the skull of the
dragon.
