This cave seems very dangerous and very man-made as you examine further
into the cave.  The walls are covered in strange sigils and runes of some
unknown language.  The cave glows with a soft blue glow, that radiates from
the walls themselves.  The glow dims and soon diminishes behind you, and
brightens ahead.  Some runes cover the walls, somewhat readable.  
  You can see the faint red outline of something moving around the area.
