Discord is brought to Ponyville to be reformed. As a safety precaution, he is deprived of his magic before his release. Naturally, he is upset by this, but... No one thought that the powerless spirit of chaos would actually run away!
Twilight Sparkle's is now the headmistress of her very own school and is ready to help mold the young minds of the next generation. But then Discord signs on as a teacher and she finds herself just as much a student as those she's leading.
Twilight manages to turn herself into a draconequus - now the only one who can help her learn to control her new chaos magic and change back is Discord. What could possibly go wrong?
