Through the power of friendship, any threat can be defeated. The inhabitants of Ponyville know this first-hand. They have seen Princess Twilight and her friends face down threats that nopony thought existed. The six of them in turn can always rely on the goodwill and cheer of their Ponyville friends and fans.
However, the plucky population of Ponyville faces its greatest threat yet. One of apocalyptic proportions. One that will need everypony's (and maybe even Discord's) help to defeat.
Bad fanfics.
Can they stand their ground against overpowered OCs, rampant shipping, and other horrors? Will Ponyville survive the onslaught? Will Vinyl Scratch ever find a time when her Bass Cannon is not the answer? All these questions and more, answered in "Canon Fodder".
