“It’s quite simple,” Discord said, off-hand. “It’s the duality my morose friend just recited for you. When you repair something, you put it back exactly the way it was before. How orderly, how dreary, what a wasted opportunity. But Mending, that’s the natural way. That’s a splint to help a broken bone grow back on its own. That’s a mutation to help a species adapt to an unfamiliar environment. That’s chaos. I am not sending you to put things back exactly as they were, as Harmony here would do. The old way is destroyed, gone forever! And good riddance to it. Life isn’t living if we aren’t changing. Even an eternal life is nothing if it’s eternal repetition. No new experiences, no risks.”
