 WARNING: You are in a CHAOTIC PLAYER KILLING room.     SW     S     SE

This suspended platform floats in mid-air, with no visible means of
support.  It is made of an indeterminate, hard, grey material, apparently
one entire, solid piece.  It is in the shape of the bottom half of a sphere,
about fifteen feet wide in diameter.  A thin, translucent bridge leads back
to the southwestern tunnels.  A heavy veil of darkness covers this entire,
expansive area, making it nearly impossible to see.  There's probably forty
feet of visibility, past which there is only an echoing expanse, impossible
to judge the size of, but extremely large.  The only things actually visible
are this platform that you're standing on, the bridge back whence you came,
and the flat, black ceiling about twenty feet above you.
