There are only six villains left in the entire world. Queen Chrysalis, Lord Tirek, Cozy Glow, King Sombra, the dread Grogar, and the Spirit of Malice and Madness known as Cosmos. All others have been reformed, seeing the light and embracing Harmony. Twilight Sparkle, ruler of Equestria, and her friends have decided to send these villains to a school where they can be reformed.

I'm sure that nothing else is going on.

...Right?
