Equestria hasn't had to worry about a mass panic or pandemic for 1000 years. Until now. When a lab accidentally unleashes an experimental substance that was meant to help cure fatal diseases, Equestria faces a constant evolving virus that could destroy their world. As mindless beings start to increase in number and roam the streets, neighbors turn on each other, families split, and best friends turn on each other. Will they survive? Or are they doomed to the fate of those already infected?
