You are at the beginning of the passageway to the throne room.  One must
take a certain route to reach the King for security.  Unfortunate for you,
only high staff of the King know the route.  As you move forward you cringe
at the chance that you might find yourself in a place you don't want to be. 
You take a deep breath, prepare yourself and continue, determined to reach
the King.
