You are walking along a narrow passage.  These halls are not used as much
as the main halls so they are not as big or as decorative.  There are candle
holders provided for light and the walls are bare stone.  
A castle guard is here checking to make sure nothing illegal is going on.
A tall castle guard bows before you.
