Prologue:
Everything happened so fast. It was unbelievable. I don't even know where to start. Should I start with what happened before? I think that would be the best place to start.
Before everything changed, my life felt normal. I would hang out with my friends everyday and I would do what most Pegasi do and control the whether. It wasn't anything special except I was a good flyer. Actually, I am. I am the best flyer in Equestria. I mean, Princess Celestia herself asked me to do a sonic rainboom at Princess Cadence and Shining Armor's wedding! How cool is that? I think that's cool and that qualifies me for my title.
On the day that everything went wrong, I was just napping on my comfortable cloud like usual. Although there were other places that I could have napped on, a cloud felt like the best spot to sleep on at the time. I could hear the blissfulness of nature while I slept on that cloud; it was nice and quiet. No one could have bugged me too while I was up there so it was great. I mean it was great until it happened.
It first started with a scream. The scream interrupted my sleep and I became very irritable because of my dislike towards waking up during a nap. I woke up half-asleep and half-irritable. I looked down at Ponyville from my cloud and tried to find out what all the fuss was about. When I looked, I saw somepony galloping down a street who was being followed by somepony else. It was a chase from the look of things. I watched from above to see what was going on between them and I hovered above to find out.
The pony that was doing the chasing looked weird. He was covered, from head-to-hoof, in this mossy like covering with tendrils growing out of his head. Maybe, I thought, they were doing some fake monster chase for Nightmare Night which was the following week at the time. So I ignored them and tried to go back to sleep on my cloud. It wasn't until I heard another scream from the same mare that was being chased that made me wake up again. This time, I became fully aware of what was happening.
The stallion that was doing the chasing caught up with the mare and he did one of the most disturbing things I had ever seen in my life. He bit her. Not like a small nibble like Pinkie Pie did to my neck when I had some pink cupcake frosting on me, he bit her with enough force to tear flesh.
I was shocked. It was like watching a horror movie except it happening in real life. I couldn't just watch as a pony was being eaten alive by some freak of nature. I had to go help. When I jumped off my cloud and landed on the ground, I heard more screams echo in the air. The killing wasn't just isolated. Everypony was being attacked by other ponies that looked just like the stallion. They were all covered in a mossy tendril coverings and covered in pony blood. I knew something was definitely wrong but I couldn't do anything to help by myself. I had to get Twilight and the others to help me. Although... something happened. I never had the chance to find all of them. Sugar Cube Corner, Twilight's Library, Rarity's Boutique, and Fluttershy's cottage were all on fire when I tried to find them and there was no trace of their bodies when I looked. Everypony either left Ponyville or died to the cannibals. The only one I managed to find was Applejack who was in the middle of packing her things to leave.
"Applejack," I asked her when I first met her. "What's going on? Why are ponies eating each other?!"
"Ain't no time to explain," Applejack said to me back as she was tying her rope around her luggage on her wagon. "Something infectious is causing everypony to eat each other. Twilight and the others have evacuated ponies that have not been bit."
"What happens if you get bit?" I continued to ask her.
"Like I said, no time . We'll meet our friends later. Come with me. We have to leave now!" Applejack said to me back again.
We never went back to look for our friends. We never came back to that dreaded place again because everywhere else in Equestria was the same. Ponies were eating each other and the carnage only seemed to get worse with each passing day. I didn't even get to find out what happened to everypony else until one day twenty years later.
