A smell wafts in from the west that makes your eyes water and your nose
wrinkle in disgust.  You think there is quite possibly no smell in the world
that is worse, until you smell the breeze that comes in from the east.  You
nearly double over in disgust from the overwhelming smell.  You can see that
the passage to the north remains relativly clean so to speak, and there is
no smell coming from that direction.
