A Nicely Lit Hallway                                   -      N      - 
(-------------------------------------------------)     - <---(M)---> -
                                                        -      S      -

The hallway continues north towards the faint sound of clanging metal,
and south towards a faint smell you recognize, but cant quite place.  It is
more like a mix of aromas that should not be mixed together.  Your curiosity
piqued, you decide that you must determine either the cause of the sounds or
what that smell is.
