Celestia's guilt for putting Luna on the moon. Luna's guilt for falling to temptation. Discord's Xanatos Gambits and chaotic machinations. Put them together and you have a recipe for a very bad time. Solar Flare, Nightmare Moon, Discord, the Changelings. Can the Elements of Harmony handle it? Or will the magic of friendship burn out in blaze of futile heroics?
