It was a warm springtime day in Ponyville, birds were chirping, fillies and colts were playing in the sunbeams, and everything seemed fine. But fate likes to play a little game called "UP YOURS PEACE!!!". Her name is Lyra Heartstrings, she's an average unicorn with an unquenchable desire to learn of humans and their hands. She and her friend, Bon Bon work in the local confectionery shop just downtown, Lyra was also there on that fateful day.

"Wow, we've seen lots of customers today, righ Lyra?" Bon Bon said as she was rolling out some liquorice from the nearby roll and handing it to a customer who immediately bore an enourmous grin.

"At this rate, we'll have that vacation in Tailhiti in no time!" Lyra said as she wrapped up some cherry bombs for two young fillies which bore a devious smirk and giggled happily upon running out the door.

Time passed since then, and finally at closing time, it happened. Lyra was closing up shop for the night and went back upstairs to her bathroom, she was brushing her teeth with her hooves for some reason, an effort which turned out to be fruitless. As she eventually got the paste onto her teeth, she received a migraine and almost blacked out completely, if not for hitting her head on the bathtub behind her. As the headache got sharper, green mist started to form around her legs, and an eerie voice along with two others said, "This is not you. Awaken your true potential, and get revenge on all who scorned you and us."

After hearing the voices, Lyra was consumed by the green mist, and her horn was being corrupted by a black aura, this went on for a minute before everything dissipated and her eyes were closed. As soon as they were opened again, her eyes had reverted to sinister-green. It was the wedding day all over again.

"Bon Bon...." She said in a sly grimdark voice, "Come out come out wherever you are..."

"Over here, Lyra. In bed, waiting for you." She said in her double ended bed, one end for her, the other end empty with the covers rolled up, waiting for Lyra to lie down and doze off, "Forgotten where your bed is?"

"Actually, i wanted to play a game with you, a game you've probably never even played before."

"Lyra, this is no time for one of your bedtime games, we've got lots of patrons to serve tomorrow."

"Do you remember what happened at the Royal Wedding?"

"Yes, The Changelings invaded, Celestia was struck down, and eventually the real Cadence and Shining Armour defeated the Changeling Army and got married, happily ever after."

"I meant do you remember what happened to me?" Lyra was getting ever so closer to Bon Bon's side of the bed, with a few dozen knives hidden in her flank pocket.

"You were invited to be one of Fake Cadence's Bridesmaids, until Twilight's friends were elected to do the job."

"Something happened when we were replaced. Something that made our lives a lot more... interesting." She was levitating some knives out of her flank, as if to slaughter the cream coloured earth pony when she stopped.

"Lyra, what are you talking about?"

"Strange voices consumed our minds, and ordered us to kill the princesses in the caves. But we were stopped by some flowers."

"OK, you've definitely been watching too much Equestria Girls. Come on it's time for bed."

"No, it's time for you to go to bed...... permanently." Lyra now revealed her hypnotized state to Bon Bon.

"What are you doing?!" She said as she noticed a dozen knives were levitated around the green unicorn.

"Night-Night. Forever!!!" Lyra's knives started to cut off all of Bon Bon's legs one by one. She screamed at the loss of her legs, both in agony and fear. And to add insult to injury, Lyra now moved the knives in an amazingly complex way, to cut open Bon Bon's stomach in a way that said "Long Live The Evil Bridesmaids.". And to finish it off, Lyra beheaded her friend with one fell swoop of all 12 blades, and then immediately tossed the head and legs into the fireplace nearby. Bon Bon was dead, and Lyra killed her. All that Lyra could say was "It feels so good to be grimdark again!"

And now we move onto the local Dentistry, where we meet our second of the three murderhorses, Her name is Doctor Colgate, she specializes in keeping teeth clean and studying time travel at the same time, and she too was there in the caves.

"Next!" Said Minuette, Colgate's newest assistant and timekeeper extroadinaire. The dentistry wasn't very busy today, as there were only three ponies waiting on the bench. As the next patient entered the dentist's room, she was asked to take a seat on the chair behind him.

"OK then, Vinyl, let's see what the damage this week is." Colgate said as she pulled up a little mouth and nose mask, flicked on a light and pulled out a little mirror on a stick with her magic and shoved it into the white unicorn's mouth, "Just as i thought, you've been brushing your teeth with your dubstep again, haven't you?"

"I can't help it doc, after all, my Cutie Mark is based around music and dubstep." She said in response after revealing her partially yellow teeth.

"I'm gonna have to drill out some of your teeth and give you fillings. It's a painful procedure that happens to naughty ponies that don't brush properly. Oh well, should have used toothpaste when you had the chance. Stay here while i grab the drill and filling cream. Colgate said as she trotted off to the office behind her and opened a draw with a dentist's drill in it. As she picked it up however, she received the same migraine, dark voices, green mist and dark magic just like Lyra did. With an evil smile on her face, Colgate stepped back into the dentist's room, with her drill in magic aura.

"Please doc, spare me this time, i've got some important songs to sing and/or remix. I promise to brush my teeth with toothpaste from now on, and i'll even cut down on some of the sweets i've been trying. Just have mercy on me!" Vinyl said as she was shaking for life in the chair's straps which were suddenly wrapped tight around her chest and hooves.

"Too late for that, my dear Vinyl Scratch. Now open wide and say aah." She said as the drill now spinning, came ever so closer to Vinyl's muzzle.

She was scared beyond belief but did as she was told, She even shut her eyes and hopefully Colgate would reconsider, but to no avail. And what Vinyl got next would scare anyone who had a dentist appointment. Instead of moving the drill towards her Vinyl's teeth like she usually did, the now possessed Colgate moved the drill towards Vinyl's chest instead, and without hesitating, stabbed her with the chest with the spinning blade, creating a big hole in Vinyl's body. As the white unicorn screamed in utter agony, Colgate ripped out Vinyl's heart and ate it right in front of her terrified eyes. Causing Vinyl Scratch to scream for a few seconds longer before collapsing to the floor as a corpse. After which, Colgate said, "Looks like Bon Bon and Lyra were right, without candy, i'd be out of business."

And finally, the 3rd and final evil one, Her name is Twinkleshine, an honorary student at Princess Celestia's School For Gifted Unicorns, and she was the last other soul in those caves on that dark fateful day.

"And as we can see by this equation, an aging/youthening spell can be chosen to be made permanent or removeable when casting it. It all depends on the caster's concentration, any questions?" Said a teacher in a spellcasting class as he was pointing at a rather complex equation that would have made Twilight Sparkle bounce up and down in giddyness.

"I have one." Said a white unicorn with a pink mane and tail raising her front-right hoof at the desk, "Can an aging/youthening spell be removed by waiting or magic?"

"Well, Twinkleshine, While someponies choose to let time take it's course, some other ponies decide to remove the spell when a certain time period has passed." The teacher responded. "Now class, not many unicorns are able to perform this spell without a little helping hand. A few examples include, getting a bunch of friends to pull off the spell, focusing really Really hard and praying for something to happen, or you could resort to the Alicorn Amulet used by Trixie not long ago. Only certain unicorns are able to perform this spell without aid or dark powers, but those unicorns have long sinced either passed away or been reincarnated as alicorns."

After he stopped, the bell rang, signalling recess. And all the classroom ponies walked out into the corridor, writing down the equation on a notepad on their way out, in an attempt to try it out once they got back to their dorm rooms. Once Twinkleshine made it back to her dorm room 2517, she pulled out the spell on a notepad and wrote it down in a textbook under her bed. However, after she finished writing the spell down on her book, the very same migraine, dark magic, green mist and evil voices consumed her, and before she knew it, she had been corrupted again.

As night fell, and all of the dorms were silent, Twinkleshine walked out into the darkness with a weird black tome in her pocket and headed for the teacher's bedroom. As she entered the room, she saw some if not all of the teachers sleeping cozily in their beds, dreaming happy dreams and trying to memorize curriculum lessons for tomorrow, when Twinkleshine opened the tome and read in whispers, a spell called "Black Hole". As her horn aura glowed in the darkness, a black vortex appeared in the room, getting larger and louder as time went by. The teachers had only woken up the second they realized that they were being pulled into the vortex with no means of escape, even their magic was effortless. Twinkleshine then closed the book and galloped back into her dorm room in silence, and began to use a dark sonar spell to relay a message to the other possessed ponies, "Sisters, it is time for us to rise again. Let all ponykind know of your grimdark wrath, then meet me at Canterlot." Next Chapter: Chapter 1: Genocide Estimated time remaining: 11 Minutes
