They had believed her to be perished in a battle long ago. But there she stood, in all the glory that was left of her. Princess Storm, the only pony in all of Equestria that could control the weather from any where with a thought.
No one could bow from the illusion they thought they were beholding in their presence. But surely if both Princess Celestia and Princess Luna could see her, then the haze wasn't a delusion after all. Unless of course, Discord had decided to play another trick on them, one he undoubtedly believed to be harmless.
"You return. . ." Luna's eyes questioned her sister standing before her. With no tail, nor main to distinguish her royalty presence, no one could say she wasn't an impostor. Yes she had the height and dialect of her sister Princesses, but that could easily be cast with a spell. The hair, for a reason not understood, when passed a thousand years, would flow with such grace and strength that no one could replicate nor question it. All she had to go on, was the storm raging outside, the one that had not been there only moments ago before the explosion sounded off her presence.
"I return after your troops did not succeed in finding me." The words were stone cold coming from someone only past had dictated as warm and kindhearted. "Tell me, Sisters, what was it like to stop searching for one of your own?" Storm began to pace the grand hall, the belts tied around her hoofs clinking together to make a sound much scratchier than bells. "Was it easy? Or did you cry yourself to sleep endless nights wishing me home? Or were you glad to be rid of me, the middle sister who merely only disobeyed the laws to win a fight."
Celestia held herself together, at least, only on the outside - no one could see what reeled inside her mind. They hoped it to be thoughts of pleasant kindness toward their sister, whom had to of only been acting this way because of her disconnection from society. No one really knew how long she was gone, but the age was clear on her face.
"We thought you burned in the fire," Celestia's words were like brittle chains against weak wrists. "Luna and I ourselves looked for you, what even may have remained of you. . ." Not even one pony within the grand hall could speak. "You were never found. We could only assume you were dead."
Storms eyes blazed with hatred. "ASSUME!" Her voice shook the hall, two of the many stained glass windows shattering in. "And I, after your futile attempts at a rescue, could only assume that you took pleasure in my assumed demise. I was alive, buried under rubble, burning under the crimson cinder that I had begun to call my fate."
"How did you survive?" Luna sliced off her words and turned her head away, realizing how cold the question had sounded against the chill in the air.
"I survived by the grace of my storms calling and the rain that pelted away the fire. Only then did I trudge up strength under the debris and nurse my own self back to health."
"Why did you not come find us?" Celestia had dropped any anger, her voice now a soft lullaby.
Storm's eyes furrowed. "Do you not see the burns that flake my pelt? I could not fly nor walk back even if I wanted to. I was weak, tired, on the verge of meeting my final fate." Her head hung low for a moment before she raised it, her eyes darker than the night. "Even if you had come back to find me, I would have hidden myself away in the curves of the mountains that surrounded me and used them as my shelter. The day you left me to burn in that fight, was the day I turned my back from being a Sister to the both of your ungrateful lives."
"Storm, please. . ." Celestia stood, begging her sister. Everyone could see where the conversation was leading, but no one wanted to speak of it for sake of sanity. "Don't berate us for a mistake that happened long ago. Let us revel in the truth that you are home, and that you have all that you need to become whole again."
Storm slammed a hoof to the ground, another window shattering at the force. "I AM WHOLE!" Tears stained her skin and her burns. "I have never been more whole in my life. The day I burned in that fire, was the day I realized I needed only myself to survive."

Half an Hour Earlier:
Twilight dug her nose into the scroll, her eyes scanning over every detail as if it were to fade away within moments.
"Is everything ready yet?" Spike leaned against her neck, his nostrils blowing away some stray hairs she hadn't pulled back from the morning rush. "I'm starving and Rarity said she wanted to eat Lunch with us."
Twilight stopped, her eyes beading down the scroll one last time before she quickly rolled it up and stuffed it in her saddle bag. "I'm sorry, Spike, but this event is just far too big for me to dilly-dally on." She sighed, trotting toward the restaurant Rarity had spoken of. "I mean, one small mistake and we may mess it all up. It's nothing like-"
"The G.G.G, ya I know. . ." Spike interrupted, holding his stomach as it growled at him for the fourth time.
"The what?" Twilight halted for a moment, her eyes darting toward Spike.
"The Grand Galloping Gala." Spike moaned, rolling his eyes.
"Oh yes," She started the journey again. "The G.G.G, why didn't I think of that." They arrived in time to see Rarity talking to one of the hosts, her eyes glimmered with passion at the decor that settled itself around her. Lamps covered in fine Persian Silk, carpets made of only the finest, smoothest fur, seats drenched in bold and passionate colors that made the place sparkle like a golden gem. It was nothing short of perfection for Rarity and her tastes.
"Oh, Twilight, Darling," Rarity stood from her seat, trotting their way when the host left. "You wouldn't believe this place to be real if someone told you about it, would you?" Her voice drenched with sultry love for the interior. "They opened only days ago and it's packed gloriously. I hadn't even expected it to be so full today, but reservations were hard to get and I'm not backing down because of a few Ponies who want to enjoy the simple things in life."
"Simple," Twilight nodded. "Very."
"I think it's simple," Spike leaped off of Twilight's back and walked toward their table that had one booth wrapped around it. "Simply beautiful."
"Oh, Spike, I'm so glad you adore it as much as I do." Rarity waited until everyone was seated before raising her hoof. "Host, we're ready whenever you are."
The one she'd been speaking with earlier trotted up to her, a pen and pad floating next to him. Smiling, he fixed his tie and bowed his head. "And how may I treat you lovely ladies today? May I interest you in our finest delectable's we have out for today? Or our main dish that is simply to die for, and already has heaping reviews from almost all of our most famous and most fashionable patrons who have visited?"
Rarity opened her mouth, but her words were met with a loud explosion that shook the restaurant. Everyone fell into a panic, their words barely but a whimper behind the noise that began to grow outside. Loud thunderstorms rolled over Canterlot, sheets of rain pelted away at the roof, demanding inside, lighting crashed outside, meeting with metal and creating a hysteria of ponies scattering into anywhere they could.
"What was that?" Rarity screeched, grabbing hold of Spike for comfort.
"I don't know," Twilight looked out the glass doors that showed the rain turning the streets into a flood way. "But it sounded like it had come from the castle, and right now Celestia and Luna were supposed to be having a meeting with the council ponies from all over Equestria."
"That doesn't sound good," Spike gulped.
"No, it isn't," Twilight stood. "And I intend to get to the bottom of it." She transported herself to the castle to find that the doors had been flung off their hinges, the solid oak no where in sight. Galloping inside, she searched for the Grand Hall where the meeting would be held. Celestia would have invited her, but she had enlisted her help other places, commenting that her wisdom was wise and deep, but unneeded for the meeting that would be taking place.
Finding the doorway into the Hall was blown off as well, she stopped at the sight of everyone watching a pony who stood on the ground floor, her voice loud and deafening. Wind shoved her back, whipping her mane to the point that she felt someone had grabbed it and was forcing her back. Pushing against the force, she worked her way into the Grand Hall where eyes fell upon her. The pony before her turned, her eyes dark and cold against the hidden sun.
Turning fulling, the pony with no cutie mark, main, or tail, faced her. Something sparked inside of her and Twilight could not hold her words back. "Princess Storm. . ."
"And you must be Princess Twilight Sparkle," Princess Storm's voice sung like a lullaby against the winds and storm. "I was wondering who my sisters had chosen to replace me. It took them longer than I had expected, but my, my, you are a poor sight to behold." She walked through through the winds as they bent to her command, and she encircled Twilight. "So small and puny, and quite a ridiculous sight. Small, main with no flare or flow - just a little pony who got lucky because of what? Friendship? . ." She laughed, her voice quaking what was left of the glass windows. She leaned in close and spoke, her voice a sharp knife slowly cutting through Twilight's ears. "Soon you will learn how easy it is for them to leave you to die and forget that you ever existed. If you are to be my replacement, you are to suffer my fate." Her laughter caught the winds and it was carried out through Canterlot.
Twilight screamed as Princess Storm used her magic to shove her out of the hall and set the doors back in place. She was carried out back to the streets and dropped into the rushing river that had once been solid brick. Holding her neck up high, she fought the current, but the rapids grabbed and plunged her deeper under the water. Reaching the top, she spattered out the water and breathed as deeply as she could before being sucked down under once more. Lighting cracked beside her, barely touching the water as it carried her farther and farther away from the castle.
Lifting herself up once more, she saw the restaurant pass her and with one sheer thought she forced what was left of her strength to transport her there. Her eyes clenched shut, she only knew that she had arrived from the tearful cries of Rarity and Spike who quickly ran to hug her. Towels were wrapped around her body to warm her and slowly she opened her eyes to the atmosphere of at least twenty other ponies glancing at her awkwardly, with a fear she'd seen and felt before.
"What happened, is everything alright?" Rarity pulled her to their booth and sat her down. "Speak to me Darling."
"No, everything's not alright. . ." Twilight looked up. "There's a Princess that has been held back in history, long dead in the battle we were celebrating today. She was of royal blood and strength and was most known for her kindness. But I'm afraid that she's back for vengeance against her Sisters and those who wiped her from history." She lowered her head, her mind sunk in thoughts. "And I'm afraid, she's far too powerful for any one of us to handle. . . I don't even believe that the Elements of Harmony will work against her."

Heyo, everybody, welcome to my story, hoped you had as much fun reading it as I did writing it. 
I'm hoping to update soon, but works going to be crazy this week, so I might have something up by next week. Mostly though, I'm going to see how this works out, because I just thought I'd have some fun with MLP:FiM because I've been re-watching some episodes and got this idea. Anywho, have a great rest of your day/night!
"At first I was super excited to come. Then I saw the storm and I thought to myself, ooooh, that's not good. But then I thought, All my friends are here, so THEN I thought to myself, everything's going to be alright. Because we're the Elements of Harmony." Pinkie hid behind her tail when the thunder clapped outside the rumbling glass window.
"I'm so sorry to have all called you here, especially at such a late hour." Twilight trotted back and forth, her head hung low in deep thought. "But I couldn't keep any of Equestria waiting. Right now Princess Celestia and Princess Luna are trapped within the Grand Hall with all the Council Ponies from around Equestria. Who is with them? . ." Her cheeks puffed out before a loud sigh sliced the tension in the room. "None other than Princess Storm herself."
"Darling," Rarity spoke up, her voice but an octave higher than fluttershy's amidst the outside. "I know you told me earlier who this, Princess Storm, was, but I don't quite understand it one bit. She's an Alicorn, that I understand, but who exactly is she and where does she reign from?"
Rainbow dash crossed her arms. "Ya, I've never heard of this - Princess Storm," She huffed, circling her hoof. "Is she some kind of impostor? Because if she were a real Princess, I'm sure we all would have learned about her in school."
"No, you wouldn't have," Twilight sat, her ears drooping. "I only learned about her when I became an Alicorn. She's the forgotten Princess, decreed so to be by the Two Sisters orders." She stood up and made her way toward the window. Looking out at the storm her head shook. "They lost her in battle, the one we were to celebrate this night. It is only Celebrated every one-thousand years to commemorate that it was the first large battle ever won by the sisters, two-thousand years after Equestria itself had been created - and one a thousand years after the Three Sisters were chosen as the Princesses."
"And why have we never heard this story before?" Applejack questioned, her brow raising with strict question. "I mean, it seems pretty important to me."
"Because Celestia and Luna despise how their reign was started."
"Do I smell a story!" Pinkie Pie gasped, her eyes growing wide as she situated herself on the nearby seat pillow.
Twilight paid no mind to her or the others as she began. "Celestia called it the Night of Descent. . . When she should have seen it coming, the repercussions of the seeds she had so heavily and eagerly sewn as a new Princess and leader of a new and barely thriving world. Her and Storm had gotten into a fight about who was the real ruler of Equestria, which undoubtedly was Celestia, but Princess Storm was always one, behind the castle walls, to question her politics. Storm was angered that she had not been a part of a decision to send out an army to fight the growing darkness that threatened to take back the land of Equestria they had all fought so hard to keep. Storm had not agreed with the plan after it was done, and so she believed, from what her sister had done - and most especially when only twenty-seven of the hundred soldiers sent, returned - that she was more fit to be the leading ruler of their beloved land."
"Thou cannot overrule us!" Celestia demanded, her hoof shaking the timid walls that had only begun construction.
"Thou believe that thou can be a better leader than I!" Princess Storm screeched back, her anger unfurling. "Thy common ponies believe I to be a better leader for this nation! Shall thou stop I from following our Common Ponies demands!"
Celestia closed the door with her magic before her sister could exit. "Thou shall not leave without thy permission. Most Especially when thou is a menace to herself and society of Common Pony."
"Thou is the menace, Celestia!"
"Please, Sisters!" Luna's voice blasted over theirs. "Do not fight in thy turn of night! Sleep now and let us rest so that in the morning, as Celestia raises our Common Ponies beloved sun, we may speak clearly."
"No, we are finished only when I speak so!" Storm threw the doors open with a growing wind and flew out.
Luna turned to her sister and sighed. "We must find our Sister before she strikes terror into thy Common Ponies."
"Our Sister shall do no harm to our Common Ponies. Her heart may not be as equal as ours, but surely her heart is equal with the Common Ponies."
"Then we rest this night, and allow our sister to relieve herself of this anger." Luna turned from her sister and began to retreat back toward her quarters. "Rest now my Sister, we shall talk with our Sister Storm in the morning, for by then she well have calmed herself."
Celestia watched her sister until she disappeared around the second floor corridor. "Our Sisters, if we do not comply with each other, our kingdom shall surely fail." Her head hung low. "Storm, thou anger for our reign, but thou love for the Common Ponies shall surely be thou end. . . And Luna, thou soul within the shoulders, hiding from the light, let not thouself be consumed." She raised her head so that her eyes watched the sky, her sister Luna flying about, watching over the young ponies of Equestria. "Let me not, thyself, be consumed by power or be estranged from thy dearly beloved sisters. For our life has not been easy, and our chosen lives have not been expected, but we shall surely survive." -
"So what they got off to a rocky start," Rainbow Dash interrupted, her voice breaking away everyone's concentration. "What's that got to do with this big hissy fit 'Princess Storm' is having now?"
"Everything, Rainbow," Twilight watched the outside world, the rain having drowned out all the roads and low shops and houses - she could only imagine what Rarity's boutique looked like now. The thunder and lightning above lit up the city that wasn't already illuminated with what minimal light that had made it through. Everything was going terrible, and the sickness in her stomach grew.
Applejack stood and clomped her hooves together. "Then we just grab the Elements of Harmony and send Princess Storm right back where she came from. Easy Peasy."
"Oh, Darling. . . Twilight already explained it to me. Princess Storm is far too powerful for us now, with what time she's had to practice, far longer than Princess Luna when she was on the moon. And with that time, she could have built an army, dozens of armies, and practiced her abilities on them until she knew she outranked her Sisters. . . And even with all that power, she doesn't even want to try and make herself look halfway decent. From what Twilight explained to me, most of her body was burned along with her tail and main." She ran her hooves down her hair. "I couldn't imagine losing something so lustrous, so wavy and free. She must be devastated."
"I'm sure from what I've heard, she doesn't care about her looks," Applejack commented.
"This isn't about looks though," Twilight groaned. "It's about something so much more than that and if we don't figure it out, we're all destined to a life living among storms. This won't be like Nightmare Moons night, it'll be worse, because the sun will be with us, but it will be blocked by storm clouds. We'll live in eternal darkness, this time not for a lust for power or respect, but for revenge on those who didn't save her and those who never knew about her." She stepped away from the window when a bolt of lightning flashed before it. "Ponies like us, the Common Ponies, used to love her, her songs, her caring nature she carried only outside of the castle walls. They sang her name in anthems, wrote her name in history books and books of the present. . . Nights were celebrated with all three Princesses where she was the most beloved as she was like a mother to all filly's and colts. Now her name is but a whisper to the wind, a forgotten mantra that people question when asked about. She's a raise of an eye, a scoff and a laugh, and worst of all for her, a memory chosen to be forgotten."
"Is there any way to stop her?" Flutteryshy asked, her voice barely audible.
"I. . ." Twilight drooped her whole body. "I don't even know."
"Then we'll figure it out," Rarity comforted, hugging her friend.
They all huddled together into a tight hug. "Together?" Her voice quavered, a feeling of dread washing over her.
"Mmhm," Their voices fit in sync and the dread disappeared with a feeling of hope and knowledge that they would, one day soon, fight and win the battle that was yet to come.

Little bit of a past story, hopefully without revealing too much, XD. I want to say a thank you to all who have favorited my story, you all are awesome and make me excited to write the next chapters that have yet to come! I'm excited to keep going because I have some things going on with this story that I really want to write out. For now though, I bid you all a good night/day
