Twilight is beyond the title protege. Prodigies are merely brilliant. Twilight has surpassed most of the greatest mages in history before the age of thirty. Twilight's research has changed the landscape itself. She is a living legend who some whisper may be the greatest user of magic to ever exist... perhaps even an equal one day to the semi-divine princesses.
But Twilight's knowledge is not infinite. She has one final lesson to learn. Twilight must learn the Final Law of Magic.
