Duel Monsters. This popular game in Equestria introduced by Discord had been the way ponies settled disputes for over a year. Little did anypony know, it was a trap devised by Discord. He brought these things called "humans" into our society a year ago, and now we're all but finished. These creatures of strange power knew more about duel monsters than any of us could imagine. Now, we're just barely surviving the onslaught of humans that keep coming. They also brought this thing called the Shadow Realm. This was what has diminished us. Even the four princesses couldn't win. This is about me, Diz, who came to be the last hope of pony kind.

Rated T for mild cursing
