Once, there were four worlds, nestled like pages in a book, each pulsing with fantastical power and connected by a single city: London. Until the magic grew too fast and forced the worlds to seal the doors between them in a desperate gamble to protect their own.

I tell them that once I graduate, I will gladly join the rest of civilized society in allowing my strength, my drive, and my focus—what they call Will—to be leeched away and added to the power of those above me, as millions already do. As all must eventually do.
