There are several guards lounging here, waiting to take their turn on
active duty in the guardpost.  Some of them are playing various dice or
board games, others are whittling and one or two are even dozing a bit. 
There are tables and chairs set against the wall for them to use while they
wait.  
A castle guard tries to keep alert during his long shift.
