Discord has once again been captured by the Mysterious Mare Do Well, AKA Twilight Sparkle, and has been brought back to the Rainbow Factory Asylum for The Criminally Insane, or the Rainbow Factory for short. But, the Dark Mare is suspicious. Discord barely put up a fight when she caught him. It turns out her suspicions are correct when Discord gets loose and takes control of the Rainbow Factory. Now Mare Do Well must figure out what Discord's planning and fend off his goons. But, what is "Titan?" What does Discord need Beast for? And what does Dr. Forever Young have to do with all of this?
