Discord was defeated. Villains always are. It’s really quite cliché.
Before he lost, he asked himself a question: what if your virtues went out of control, rather than your flaws? Perhaps if the heroes and villains weren't so clear-cut, the conclusion wouldn't be so inevitable. If nothing else, there would be some fun chaos along the way!
Can the main six find a way to undo Discord's magic, in spite of themselves and each other?
Disclaimer; I have been working on this for a while, and the writing at the beginning is not as good as the writing later. Hopefully it is not too great of an impediment to the story.
