Prologue
The Princess looked at the remains of her once great empire. The meteors had come so soon, they weren't ready. Not even the physical embodiments of the elements of harmony had made it past the first stages of the game. The princess shed a tear as her sister walked into the room.
“Sister, you did your best. We must accept our fate now. Every great civilization is meant to fall at one time or another.”
The princess turned, “Not like this Luna! They are meant to gradually die or be taken over by opposing kingdom. Not slaughtered in some sick twisted game that the Gods have decided to play!”
Luna took a step back, he sister wasn't normally like this, “Tia, what is the matter?”
The princess looked enraged at this, “The matter? Look at this Luna! Look at the craters left behind from the meteors! All we have worked for is dead! Nothing remains of Equestria but craters! And there is no sign of stopping!” The princess walked out to look at the carnage that remained of her society. It had only been yesterday when the meteors started coming. No, that was the past and she couldn't think about it anymore. “Live in the present” her mother used to say.
“But Tia, it's not your fault!” Luna said running outside after her sister.
“Then whose fault is it Luna? Those accursed humans who started talking to my pupils? Twilight Sparkle for initiating the chain? Or perhaps you want to blame it yourself?” the princess turned to face her sister, “You know very well whose fault it was.” A meteor exploded against the shield protecting the floating city of Canterlot, the mountain that had once held it now destroyed.
“You cannot blame him! You saw this coming as well as I did! Dark Dawn is not the source of our problems! Whether or not he played it still would have come! The Reckoning always comes! No matter what session!”
The princess sighed, her sister was right. Another meteor hit the shield and the princess fell to the ground, Luna's horn instantly flared up with magic as her sister temporarily lost control of the shield holding Canterlot in place. Luna's knees buckled as she tried to hold the shield in place. She wasn't used to holding this much magic. Her sister finally maintained her composure and nudged Luna telling her she could stop now. Luna's horn finished emitting magic and The Princess continued powering Canterlot's floating city.
Luna looked at her sister with worry, “You know we can't keep powering the city for long. It might almost be time for us to leave.”
Princess Celestia looked down as Luna continued, “We can't keep the castle safe and maintain the shield for much longer, you've been doing it for a full twenty four hours. You know better then I do that the meteors are just going to keep coming. This is a doomed timeline. We must go.”
“No. You must go. I will keep the city powered for as long as I can, and then...”
Luna looked shocked, “But Celestia, you can't possibly leave yourself all alone here! What if you die? I couldn't possibly bear the thought!”
“Then you know you must make the mission succeed. Take the TARDIS and go”
Luna opened her mouth to speak but then turned to walk away, before she did she turned back and embraced her sister, “I love you Tia. Please don't die.”
Celestia smiled, “Then you must make sure your mission is a success. Now go bef-” before she could finish a massive meteor hit the shield, shattering it, Celestia screamed out in pain as the spell protecting the castle was now done
“TIA!!!” Luna turned and ran for her sister but Celestia's magic caught her and teleported her to the basement where the Tardis was. An explosion rocked the ground around her and she suddenly couldn't feel the presence of her sister anymore, it was over.... Princess Celestia... was dead. Luna wiped away her tears and ran through the corridors towards where they had hid the Tardis.
Luna ran through the empty halls toward the tardis as she suddenly realized she was thrown onto the ceiling. The TARDIS was nearby, she could feel it but the city was falling from the sky, She screamed as she faced her doom coming towards her but out of the corner of her eye she saw the Tardis heading down the hallway, she used the last bit of her magic to teleport to the door. She whipped open the door, jumped in and slammed the door shut. She closed her eyes and listened to the flow of the timestream as this doomed timeline came to an end, She opened her eyes and flipped a switch and jettisoned herself back into the past.
Chapter 2: 12 days before Reckoning
A lone statue sat in a garden, it's face frozen in a state of pure terror frozen on it's face. The creature this statue embodied was that of a draconequus, but it was no ordinary statue, This statue held the God of pure chaos, Discord. Having once tried to plunge Equestria into eternal chaos he had been thwartedby Twilight Sparkle and her little band of ponies and thrust back into a state of eternal prison by their Pathetic Elements of Harmony. However he could hardly call a path of magic that trapped one in stone pathetic. He had almost managed to harness their power before Twilight Sparkle had interfered and thrust him back into this prison. Curse you Twilight. He thought as this stupid look was plastered on his face. This close, only five more minutes and Equestria would have been mine for all of Eternity. Well, at least until the Reckoning. How long until that? I believe it should be about twelve days. Yes, twelve days until I am once again free from this prison. Being an omniscient being was quite useless when there was nothing to do with it, having all that knowledge but being trapped in stone. Though with all his knowledge he could never figure out how the Elements of harmony worked.
Twilight Sparkle and her friends proved to be quite the nuisance. If only there was something I could do, to go back in time then Equestria would be mine. If only I could get out. Out of this stone cold prison, Bound in eternity to let me reflect. That Princess and her meddling ways! OH CELESTIA WHY! He took a deep breath in his stone prison. Though on the outside he was frozen, on the inside he was free to wander about in a field of neverending blackness. Patience. Patience was all he needed, You waited eons to escape. You can wait twelve days. Twelve days and then Chaos shall flood throughout the planet. Though if Only I had an eye. An eye into the chaos. As Discord walked along the blackness a pinprick of light appeared in the distance. Could it be? A crack? A flaw in the Elements of Harmony's prison?He rushed over and basked in the wonderful light. At last something to work with, something to see what was going on out there. He stroked the crack with his paw and felt the energy of the light flow out. What's this? There is time displacement in this crack. If I send a form out then it might not actually reach Equestria until.... Discord smiled, perfect. This will do just nicely.
Discord let his energy flow out of the crack and into the world behind it. Finally something to stave off this boredom. He closed his eyes and drifted into sleep as he let his consciousness drift into the world behind the crack.
??? before the Reckoning
Outside smoke gathered around the statue of a smug draconequus and formed itself into a unicorn. The unicorn stood tall as it opened it's eyes to the world around it. It looked about trying to find out exactly what time it was. The unicorn took a step and tried not to fall on his face. It had never walked on four legs before. Two legs had always been the way to go, or even floating. The Unicorn looked back at his flank, wondering if a cutie mark as was so popular had appeared upon it. He looked and saw nothing, but he knew better than that. Though his coat was black, his cutie mark was that of a black hole, the perfect symbol for chaos.
The Unicorn smiled as it took a couple more steps and then entered into a full gallop. With a smile his horn lit up with blackness and his form disappeared in a poof of smoke. The black stallion looked up, it was night about now, and the moon was full, But there was a strange shape in the moon. It looked like a mare, but he couldn't tell perhaps someone else might know, he'd have to ask a pony later. For now, he had to start his journey to Ponyville, that's where the collective knowledge on the Elements of Harmony were.
Perhaps all that study was not for naught, I can still use what I know, and learn more from that book in Twilight's library, though if I'm correct Twilight still lives in Canterlot... Perhaps I should pay her a visit.
