An Incredibly Hazy Chamber                             NW     N     NE

As you step into this room, you are overcome by an intense fit of
coughing.  The air is thick with a toxic black smoke of some kind, making it
impossible to see anything.  When you finally recover you are totally
disoriented, and have no idea where you came from.  You can make out the
vague outlines of several doorways, but have no way of telling where any of
them lead.  
You feel dizzy, and everything seems to spin around you.
