Approaching a Ritual Chamber                           NW     N     NE

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

Energy flows furiously like gusts of wind around the turns of the diamond
forming an invisible barrier.  Magical barriers like this have been raised
to contain experiments from causing disasters and to harness all of the
power within a concentrated area.  An eerie glowing light emits from runes
sketched all around and rises in a thin blanket towards the arched apex. 
From the north, murmurs of chanting can be heard.
