You are at a corner of the Castle, you look up and see a long ladder made
of iron leading up the tower.  From there archers can easily pick off
invaders on the ground.  The cold dark walls leading up are lighted by
torches on the walls, providing enough light for you to make your way up. 
From the tower one can see Vospire at a new perspective, and also see the
great Mount Vesuvius.  From the wealthy look of the castle, you can only
assume that the king and the people are wealthy too.
