The Great Equestrian Virus

The creature strapped down to the table was not of ponykind. It looked like a pony, but it wasn't a pony. It pushed against the ropes that held it down and growled at the unicorn doctors standing over it. Celestia had even come down from the castle to see what the ponies had found. There were three more ponies lying sleeping next to it. They had apparently been bitten by the creature and had passed out soon after. The three of them looked pale and blood ran down their necks or legs where they had been bitten. The creature groaned at the unicorns and pushed against its bonds again as the Sun Goddess looked over it.

"Doctor, what is wrong with this pony?" Celestia asked.

"We are not sure. I have cast spells to look at it through X-ray, and I can tell you one thing Princess. That creature, its heart doesn't beat, it doesn't breathe, or get hungry, it doesn't do anything a living thing would, the only thing left, alive, is its brain. And not as much as any pony, just a small piece of it. This thing. It isn't alive, we don't know what is wrong or how it happened but it has happened, this pony is dead." The unicorn doctor replied.

"What of those three." Celestia asked.

"They were bitten and just, passed out. They have been like this for hours. They were all bitten around the same time. They are weakening more and more and may die. There is nothing we can do." The unicorn replied.

"Thank you doctor. I shall be going now." Celestia replied. She turned to leave and there was a low groan coming from one of the ponies that had been bit. Celestia looked to it and saw it was awake. Its eyes white and dull. The pony got up slowly and walked forward, groaning again.

"Hello? Are you okay. How do you feel?" The unicorn doctor asked. The pony turned to the doctor and groaned again, then lunged forward and bit into its neck. Blood sprayed out over the hospital floor and the doctor screamed and feel to the ground. Ponies suddenly screamed as the other two ponies stood and galloped toward ponies, biting into the panicking ponies. Celestia stepped back to the doorway. Shouting for guards. They ran in with weapons and armour. Charging at the corrupt creatures, the bitten were slowly rising up as well, more and more ponies dying and, changing. Celestia felt a push of a guard; he had been bit on the neck and was bleeding out.

"Run! Princess run!" He shouted, his eyes turning white and coughing blood out of his mouth. The guard slumped down, before slowly groaning and growling at the princess. Celestia stepped back again and ran out of the room, screams and groans following behind her.

Celestia made her way to the castle; ponies were panicking all through Canterlot, hearing the fighting and panic of the hospital. Those things swarmed out after Celestia, attacking ponies as they went, unicorns shot spells and fire at the creatures but they kept coming. Spears and swords had no effect to the creatures either. They wouldn't die.

Celestia ran through the castle, ordering guards to close and lock the doors behind her, they did. Shouts from ponies followed and they banged on the doors, trying to get in.

"Do not open those doors! Those things out there are not of pony kind!" Celestia shouted. "Mother please forgive me for abandoning those ponies outside." Celestia muttered. The air filled with groans now, the sounds of those corrupt, not those of the normal ponies.

"What in Equestria is that?" Luna asked. She had obviously been woken up by the noises and was walking down the stairs of the castle, rubbing her eyes with one hoof.

"Luna, get some supplies, we are leaving." Celestia ordered.

"Sister?"

"Ponies are, changing. I don't know how to explain it. If you get bitten, you change, only wanting to bite more ponies. They are swarming Canterlot. We need to leave, get to Ponyville and warn them. Move!" Celestia shouted. She then looked to the guards standing at the doorway.

"What are our orders princess?" Shining Armor asked.

"Tell the men to evacuate. I want a few to defend the doors until we are ready, then we are all evacuating to find your sister. Go find Cadence." Celestia replied. Armor nodded and turned.

"You heard her! Hold the doors until we are ready. It's time to leave!" Shining Armor shouted. A window smashed and a few corrupt ponies fell down, they had made a pony made ladder to the window to get in. The creatures groaned and smashed to the ground, they slowly got back up, limping from broken limbs. Blood dripping down.

"Princesses! Get out of here. Ponies. With me!" Shining Armor shouted, aiming his spear down.

"It's been an honour sir." A pony muttered as the guards charged forward.

"Celestia. Keep Cadence safe!" Shining Armor shouted, then a pony bit into his neck and he screamed in pain. He fell down. Celestia heard herself counting. "One...Two...Three...Four...Five...Six..." At this point Shining's body was moving and he was screaming against the corruption, his eyes changing colour and his limbs going through uncontrollable spasms. "..Ten...Eleven...Twelve...Thirteen..." His body had now gotten up; it stood prone for a second before groaning and looking to the princesses. It lunged forward. "Fifteen." Celestia shouted and ran; Luna quickly took flight and followed. A corrupt pony jumped at her and Luna screamed out.

"Luna!" Celestia shouted, looking to her sister. Blood dripped down Luna's leg and she crashed down to the floor. Celestia was too high up to be grabbed but nearly fell herself at the sight.

"Sister!" Celestia shouted, shooting a spell at the creature biting into her. The creatures head was blasted off and the body flopped down. The jaw was still biting at the air.

"Tia. Tia. I am, I-. I am so, so sorry. Goodbye sister." Luna muttered and shut her eyes. Corrupt ponies swarmed around Luna as they jumped to Celestia.

"Me too Luna. Me too." Celestia muttered. She felt tears forming but knew she couldn't do anything about it. Her sister was already getting back up and was groaning. Celestia let a tear drop and flow out of the window, cried and screams quickly followed. "Mother, what have you done?" Celestia asked to her mother.
