Shimmering geometric patterns of black and silver adorn the walls of the
tower.  The designs are placed at oddly calculated intervals which make you
feel dizzy when you stare at them for too long.  Upon closer inspection you
notice that these are not designs but large moths that have attached
themselves to the walls, most likely to feed on the moss that grows freely
there.
What appears to be a random geometric figure on the wall suddenly moves!
