An Indigo Tunnel                                       -      N      -

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

As you continue down the tunnel, the indigo of the rock walls begins to
become much darker, until it is almost black in color.  There is obviously
some kind of magic at work here, since these passages seem to shift and
change as you follow them.  Such tunnels could not have been created by
hand, and you are now almost certain that the sorceress Baba Yaga is
responsible.
