(This was my first fic. It honestly isn't that good. My other fics are MUCH better.)
Twilight Sparkle unknowingly starts an outbreak of a deadly plague upon the land. The disease kills everypony it infects, the trouble is, they don't stay dead. Instead, they live again, becoming ravenous cannibals that will stop at nothing for their next meal. Now, a group of survivors must make their way to Canterlot, only then will they be safe -- or as safe as they can be.
