BLANKET OF DARKNESS

'BLANKET OF DARKNESS'
Syntax: commune 'blanket of darkness'

A dark mist seeps through the room, completely blocking all sunlight and
visibility from outside.  While inside, you are also isolated from the
surrounding environment.  You will not be able to teleport or scan out, 
and no one will be able to teleport or scan in.  Only by foot, can you 
leave this blanket of evil and darkness.
