You are walking down an ashy tunnel.  Ash covers the floor of this narrow
tunnel as it continues on into darkness.  The tunnel walls are covered with
odd runes and scripture that you can't understand.  The upper part of the
volcano is lighted by torches along the walls put there by brave men who
dared to explore the volcano that nearly destroyed their people.  The tunnel
continues on into the darkness.
