You have reached a brightly-lit, three-way intersection in the caverns. 
There are numerous globes of light bobbing near the ceiling, each of them a
different color.  To the west is a long passage leading back to the first
level of the caverns, while passages north and south lead to different areas
on the second level.  You hear the scrape of claws on the stone floor close
by.  You wonder what sort of animal calls this place home.
