Wolves of Hogwarts

Harry Potter has a secret. Even for a world of magic, his secret is big. Every full moon, he transforms into a wolf, but is not a werewolf. HE is a therion, a creature thought as a myth within his world. How will this secret change him and the story. This will be be a Harry/multi fic, but not in the way you think. Rated M for certain reasons. NO BASHING.
