Harry smiled as he looked on at the sixth years practicing the patronus charm. It had been five years since the war against Voldemort, and he still couldn't quite believe that spells like these were no longer necessary for survival. He congratulated each child as they cast their first full patronuses, some small, some tall. A moose, a cat, even a pygmy puff! He came to the last student, and gasped. Standing there, glowing proudly, was a gigantic creature, with the wings of an eagle, body of a lion and the gills of a fish. He looked to the girl that had cast the patronus, sure he would find her gaping at it like he was. Instead, she was wearing a small smile, and Harry remembered that just because the biggest war was won, didn't mean they all were. Sometimes, to fight the monster under the bed, you had to create an even bigger one.
