  You are standing on top of a grassy plateau.  The area is covered with
vines that tangle around your feet, almost as if to keep you here.  By now
you realize that you are not alone, these silent stalkers are deadly
killers.  You decide that perhaps it is best to leave while you still can. 
Either way, it would be best to not stand in one place for very long.
A silent moving shadow slips across the walls.
