This small indentation in the ground looks as though it was already here
when the city arrived from above.  However, over time it has become filled
with rubble and other discarded pieces of junk.  Scavengers must discard
most of their unwanted items here, and you doubt that there is anything
useful at all in this area.  
A large stalactite is dislodged from the ceiling, narrowly missing you!
