Long before she had met anyone in Ponyville, before she knew friendship, Twilight was a self-exiled scholar. (much like myself) She tried to find out how to spend more of her time studying and less time with others. Eventually she came across a spell that could take her to a dimension filled with nothing but the endless knowledge of the universe. She spent what seemed like several days inside the huge collection of books and knowledge, but something felt wrong with the place. Like nothing she had ever felt before, like the place seemed to be drawing something from her. Scared, she left the dimension to ask Princess Celestia about it. When she exited the dimension she had discovered that only several minutes had passed. Confused and scared, she ran out of the library.

Twilight got up to the Princesses private chamber and was allowed access by the Royal unicorn guards outside. She told Celestia about the realm she had discovered. And the Princess looked angry. “What’s wrong?” Twilight asked, stepping back sheepishly. Celestia Responded “Where did you find this spell?” Twilight then said “I found it in one of the books you gave me. Am I in trouble?” Celestias expression lightened, “No my faithful student, you are not in trouble. But I am afraid that I cannot let you keep your knowledge of this spell, at least not until your older. Please stand still.” Twilight complied with the request, standing absolutely still, not even breathing. Her face had started to turn an odd color when Celestia noticed, “You can breathe.”

Twilight exhaled sharply, and then blushed. Celestia simply smiled and shook her head as she resumed powering up her spell. Twilight asked “What are you going to do to me?” Celestia replied “I am going to erase all your memory of this dimension, the spell and the book you found it in.” Twilight leaned back away from her teacher, “will it hurt?” Celestia shook her head, “I should believe not, as I’ve had to use it on you once before.” Twilight curled here face up in confusion and shock, “What?” Celestia chuckled “I was just joking. Now hold still.” She brought the tip of her horn down to touch Twilights, and she fell unconscious. Celestia looked over the unconscious form of her student with worry, “Nothing good will come from this.” She thought as she levitated Twilights unconscious body onto her back, giggling slightly at the adorable snores coming from her favorite student. She sighed at the thought of having to explain herself if Twilight ever found out what she had done.

MANY YEARS LATER

Twilight Sparkle was at a small birthday party, when she received a letter from Princess Celestia explaining something odd.

To my faithful student, Twilight Sparkle
I regret to inform you that at one point in the past, I had to modify your memory to protect from harm. I feel that you are now of a proper age to handle the spell I had removed from your memory. It is my hope that you would find a proper use for this spell and one day figure out how it can be used for the benefit of everypony.

Happy Birthday, my beloved student.

From Princess Celestia
Ps. I’m having the spell copied from its book as I’m writing this letter, it should take a few days. And try not to go crazy again.
Twilight looked over the letter again and again, wondering what kind of spell she had found that would’ve prompted the princess to take such an extreme measure. “Maybe I’d discovered dark magic too soon, maybe the banishment spell, or possibly a combat spell, or somet...GAHK” She found a hoof shoved into her mouth. “Calm down there, Sugarcube. ‘Ahm sure the princess had a perfectly good reason for blanking your memory like that.” Applejack said to her panicking friend.

Despite Applejacks pleading, Twilight refused to stay calm. She ended up pacing the library for hours on end which isn’t strange for Twilight, as she tends to do this quite often when nervous. “Twilight, could you at least try to relax?” Spike asked. “I don’t know how YOU could be so calm.” Twilight replied. Spike simply pointed to a clock and said, “3 A.M.” Twilight looked up at the clock in confusion, “how much time passed?” She thought to herself. “Ok, I’ll try to get some sleep.” Spike glared at her, “Use that knockout spell you learned a few weeks ago.” Twilight replied “Remind me again why I studied that.” Spike replied “Because it’s relevant to the plot of the story?” Twilight looked him with a look of extreme confusion, “WHAT?!?!” Spike sheepishly backed away, “I’ve been spending way too much time with Pinkie Pie.” Twilight right eye started to twitch and made to ask a question, but decided against it as it would bring up more questions than it answered. “Whatever, let’s just get some sleep.”

After tending to Spike and making sure the library was set for the night, Twilight hopped into her bed and had cast the knockout spell onto herself, but she had made some minor alterations to it so that instead of simply knocking her unconscious it would induce a natural sleep. Simply put, it was a sleeping spell. After a few moments of drifting lazily through some clouds, she realized “I’m not a Pegasus.” She then fell to the ground and hit with a thud. She got up and rubbed the dirt off of herself before moving on into town. It seemed eerily deserted, “Where is everypony?” She shouted. In the distance she could hear a voice say her name, it was quite faint. She would’ve even heard it at all if one of her ears hadn’t been tilted in that direction. She started toward the voice at a normal pace. The voice getting louder and louder. Suddenly the voice stopped, she looked around at the abandoned town, and tried to convince herself that none of it was real. “It’s just a dream, It’s just a dream….” She continued her mantra. She closed her eyes in a feeble attempt to wake herself. When she opened them again, she was terrified at the sight in front of her. All her friends, their bodies twisted and mangled. Rainbow Dash, her mane in pieces, her right wing bent and broke with the bones piercing the skin and her left wing in a similar state, but with it broken in two places. Her gut sliced open along the sides, intestines dragging along the ground. Her face covered in cuts and bruises and her left eye dangling from its socket. The rest of them were in similar, if not worse shapes. Among them being Fluttershy, Applejack, Rarity, and Pinkie Pie. With Pinkie having a rather demented looking smile on her face that would Celestia cringe.

“Why did you do this to us?” The mangled bit of flesh that was Fluttershy asked. Rainbow said “I thought we were your friends.” Pinkie added “We wanted to party with you.” Rarity added “We loved you.” Applejack said “And all you did was torture us.” Twilight replied “What did I do?” Rainbow replied “Isn’t it obvious? You betrayed us.” Twilight was shocked by this statement, “Why would I betray my friends?” Fluttershy spoke up, in a manner highly unlike her, “You never were friends with us, you were using us the complete your goals.” Pinkie said, “It doesn’t matter to us anymore.” Applejack “We have nothing more to say to you, murderer.” If Twilight was shocked before, now she was terrified. “W-W-W-What do you mean?” Rainbow replied “You killed Princess Celestia.” Twilight was tearing up. Applejack laughed, “Ok look, the cold killer’s crying.” Rarity said “She doesn’t deserve the pleasure of being able to cry.” Pinkie said, “I agree.” She looked over at Twilight “Your number has come up.” And she pulled a knife out of her mane. The rest of her friends pulled out similar knifes from various parts of their bodies, rainbow pulling one from her broken wing, Fluttershy pulling one from her eye, Rarity pulled one from her leg and Applejack pulled one from her ribs. Each new open wound gushing out blood as the offending object was removed.

They began approaching Twilight, shortly after Rainbow jumped at Twilight stabbing her in one of her rear legs, pain shooting up along Twilights nerves causing them to shut down, paralyzing that legs. Fluttershy leaped next burying the knife into Twilight marehood, twisting it as if to cause insult to injury. Applejack jabbed the knife into Twilights right eyes, causing a third jolt of pain and more screaming from the now utterly crippled, used-to-be mare. Rarity jumped and tried to stab Twilights mane, failing that she put her knife to twilights flank and cut out her cutie marks then moved over to her head and cut off Twilights horn. Pinkie pouted, she spoke up and said “That was my idea.” Rarity laughed and said better luck next time.” Pinkie walked over and stabbed Twilight in the gut, twisting the knife in full circles. Pinkie then flipped Twilight onto her back and Said “There is one more who would like to speak with you.” Twilight looked through her one remaining eye at the sight of an alicorn walking towards her. But something was wrong. The alicorns wings were broken and shattered, horn ripped in 2 and barely hanging, cuts all over its body, its gut ripped completely open with most of its organs dragging behind it. Its coat was completely soaked with blood and other juices. Its mane reduced to nothing more than cinders. Then Twilight saw its cutie mark, the sun. This was Princess Celestia walking up to her. The princess had walked over to Twilight without are simply thought to how she was able to accomplish it, and said “I knew this day would come, and yet I let it happen. You will bring about the deaths of tens of thousands all because I made a mistake. NO. You are the Soul case of this, and you WILL be punished. I, Princess Celestia, hereby expel you from the School for gifted unicorns, renounce you as my student, declare you an enemy of Equestria, and sentence you to death for the murder of tens of thousands.” She began walking towards Twilight, who was trying to crawl away. Celestia pulled a knife out of the center of her chest and took the knife in her magic. “It is only fitting that you be killed in the same way that you killed me.” The Celestia plunged the knife directly into Twilights heart.

Twilight jumped out of bed, screaming loudly. Spike immediately rushed to her side. “What’s wrong Twilight?” She shook her head, and through her immense, paralyzing fear, she heard Spike, but couldn’t respond. After 30 seconds, the full weight of the dream dropped down on her like a ton of bricks and she started crying uncontrollably. Spike hopped up into Twilight bed and embraced her in an attempt to comfort her. “It’s ok, it was only a dream.” Twilight her him, and said through the tears “Only a dream…” She repeated her mantra a few more times before laying back down; Spike was just about to hop off the bed when he heard Twilight say “Don’t leave me. Please stay with me.” Spike crawled back over to her, “are you sure?” Twilight nodded. She put a forelimb over him and they fell asleep again shortly. The nightmare didn’t return and she slept peacefully for the rest of the night.

Off in Canterlot, Princess Luna was dreamwalking, when she stumbled across Twilights nightmare. “That is quite troubling. And so soon after Celestia sent……no I must be simply nerves. I truly hope that IT hasn’t returned”. Luna noticed that Twilight had awoken from her dream, And she said to herself “Rest well young one, for tonight I shall watch over you.”

Author's Note

I may or may not make something of this. It depends on how people react to it.

The plot is largely undeveloped, because I kind of just put this together after going on a grimdark reading spree.

I know it says, "Dark and tragedy" But I can't help but throw in a few lighthearted moments.
