“No one would come right out and say it, but the worldwide magical ecology was suffering from a serious imbalance: too many magicians, not enough monsters.”
–The Magicians – Lev Grossman
Let’s suppose there is a magical planet named Fillory that your siblings have found a way to visit from Earth via a magical doorway. However, you never get to stay and it is the only place in the universe that you want to be. One day you find a spring that holds all the magic and you drink from it giving you the power the stay, but it also gives you unimaginable magical power. What do you do?
Those of us who love The Magicians know what happens next. The power of magic absorbs the boy who becomes The Beast and he almost dries up all of magic for Fillory and Earth in his unending thirst for the power of magic.
