 WARNING: You are in a LAWFUL PLAYER KILLING room.      -      S      -

You are walking through a narrow, circular tunnel leading into the depths
of the mountain.  The edges of the corridor are very smooth, almost as if
they had been melted away.  Perhaps these tunnels were originally conduits
for flowing lava, which proves that Hellbent Mountain must indeed be a
volcano.  You hope that there isn't going to be an eruption any time soon,
or else you could be in some serious trouble.
