"Ok, now that that's over with, I need to ask you both a vital question." Twilight said as Human Diamond and Silver took a seat on the bottom floor, "Did you two notice anything different about Ponyville during your little, conflict with your pony selves?"
"In all honesty, I wasn't really paying any attention to the battlefield around me." Human Diamond spoke to her, "I had one goal to achieve, making sure my evil pony self was taught a lesson she'd never forget!"
"Actually." Human Silver started this time as she raised her hand, "I did notice the sky had turned black and fiery whilst I was pushing back my evil pony's sword. Although it looked pretty scary at first, I quickly shrugged it off and focused on my target as well."
"What you two caused was a temporal abnormality." Twilight got all science-y on the two humans, "A slight change in the world's balance that can quickly escalate to the planet's detonation."
"Hold on, I'm confused here." Human Diamond stopped her, "What did we ever do to cause this event?"
"Diamond Tiara and Silver Spoon of the human world. You and your pony selves are both the same life-form, if both your pony selves and your human bodies touch, that counts as a paradox. And a paradox quickly creates hundreds upon thousands of temporal abnormalities." Twilight explained, "If these paradoxes continue to occur, who knows what could happen?"
"I can guess." Silver stated as she knew what was coming next.
"It could not only corrupt the balance of both our worlds on a colossal, life-threatening scale. But it could also remove you and your pony selves from existence altogether."
"Corrupt?" Diamond asked as she heard each word carefully and precisely, and growing a face of worry as each word impacted her ears.
"When I came to your world a few months back, Celestia only allowed me and Spike to travel there. It was for the best however, there were human doubles of all my friends there. and I assumed that if my pony friends came with me, it would cause temporal havoc on more worlds than just Canterlot High and Equestria."
"So, how do we stop these paradoxes?" Diamond asked after Twilight had stopped explaining, "Hopefully it doesn't involve making up with our other selves."
"It's simple." Twilight began, "We need to get the portal open and get you two back home. Once balance is restored to both our worlds, things should start to settle down."
"Ok, we need to get the portal open, but so far we've come to the conclusion that Twilight hasn't read the book to force it open yet. What should we do?" Silver asked once the task was presented to them.
"Celestia's Castle or the library in Canterlot could house the book we need." Twilight told them as she conjured up some visual aids of the town and castle, "We need to find the a book that has anything to do with the portal and its' workings."
"I don't think that's really gonna be a good idea." Diamond said once they heard that they were gonna head out of town, "If the ponies of Equestria have never seen a human before, they might start to panic and worry. I don't want to see that."
"Don't worry, I'll clear up any suspicions with the townsponies, Celestia and/or Luna might not be surprised however. They know the human species well."
"Quick question, how do Celestia and Luna know about us?"
"It was Celestia and Luna as well as my sister Cadence who told me about the portal and gave me an in depth analysis once I got back from the 3rd day." Twilight told them both.
"When should we be off then?" Silver asked once Twilight had finished.
"We could go right now." Twilight said, "I'm not at all busy today and Spike can cover for me as long as we're out."
"But how? Spike's just a little... um... help me out here would ya, Twi?"
"In this world, he was born and raised as a baby dragon. Although he does act a lot more mature than his title depicts." Twilight began, "Don't judge him by his size, Spike has often been very useful at times."
"She's right, you know." Spike started, "Did she tell you of the return of the Crystal Empire yet? That was me that played a big part in that tale."
"Alright, Spike. we know you've been busy with your business, but i need you to hold down the fort while me, Diamond and Silver are out." Twilight stated the task to him.
"Don't worry, i've got this." Spike said as he slid down the banister before clumsily landing on his face at the end of it, "I'll be fine. thick scales after all."
"Now then, shall we?" Twilight walked the two human girls to the train station and got on board. It was a law in Equestria that all princesses and their friends ride for free. The train was similar to the one Diamond and Silver took from the Crystal Empire and just like before, they had to lean back to avoid scraping their heads on the roof. The train ride lasted roughly 10 minutes as the three girls ascended the mountainous tracks to reach the city.
______________________________
Once they arrived in Canterlot, the two teens could not withhold their excitement any longer. They could tell from first glance that Canterlot was the classiest city in this new world, and their eyes were darting across fancy shop to fancy shop in mere seconds.
"Wow, i've never seen so much elegance packed into one little city." Diamond started once she calmed down a little, "How did you ponies manage to pull this off?"
Twilight chuckled a little, You didn't really think ponies were stupid animals did you?" She joked, "While most ponies were accustomed to farm work, a select few decided to take the higher-class route in life and thus, Canterlot was born."
"There's so much stuff to see and possibly do here." Human Silver said as she looked into each window with curiosity, "There's jewelry, clothing and high-class merchandising as far as the eye can see. I must have died and gone to heaven!"
"Focus, Silver." Twilight told her, "We need to find that book in the library before-"
Before she could continue, Human Silver was ensnared in a magical aura and levitated off the ground. It wasn't long before the same yellow aura wrapped itself around Human Diamond and sent the two off of the ground.
"Twilight." A familiar figure explained as she blocked her light. Twilight needed only to see the multicoloured flowing mane to know who it was. It was Celestia, and she didn't look very pleasant, "Would you care to explain to me what two humans are doing in Equestria?"
"Trust me, Princess Celestia, it's a very long story." Twilight said as the two humans were carried against their will to the throne room in Celestia's aura, with Twilight following close behind.
"I don't understand." Diamond said as they went through a set of double doors in one corridor, "What does she want with us?"
"Celestia must have thought all humans have a darker side just waiting to be unleashed." Twilight said to her, "She believes that everyone in the human world has a demon form, and she's come to the conclusion that humans aren't to be trusted."
"So what are we supposed to do?!" Silver asked once the throne appeared through the next set of doors, "Just sit around twiddling our thumbs until she gives us the death penalty?"
"I swear to god, i don't even know why they made us do the renaissance last term." Diamond said to Silver once she stopped, "It just seems stupid and make-believe."
"Don't worry, you two." Twilight said as Celestia conjured a cage over them both, "I'm gonna get you both out of here, alive. But you just need to let me do the talking."
The guards sheathed their spears once the cage materialized and Celestia took a seat on the throne, her sister Luna doing so shortly after.
"I had hoped this day would never come." Celestia started to speak to her three guests, "I never thought humans could be deemed fit to exist in Equestria after i saw that, that thing from your travels."
"In all honesty, Celestia." Twilight started, "These two are actual humans. The only reason Sunset Shimmer took a darker form, was because she wasn't human to begin with, so it just seems logical that no other human has a darker side."
"Still, how they got here is important." Celestia said as she came closer to the two humans, looking a little enraged and suspicious, "Who are you? How did you get here? And who sent you? Was it Chrysalis? Sombra? Figures they would send a spy to extract information for themselves."
"I'm Diamond Tia-"
I DON'T WANT YOUR BACKSTORIES!!!" Celestia said, clearly consumed by rage and despair, "I WANT THE TRUTH!!! TELL ME HOW YOU BYPASSED THE SEALED PORTAL OR I WILL BE FORCED TO EXECUTE YOU BOTH!!!"
"Sealed portal?" Silver began, "We didn't even know it was a portal or when it was sealed in the first place."
"Just shut it, different flesh!" Celestia threatened them now, a motive she never used before in the past, "I will have no more of your stupid accusations or any other-"
"THE PORTAL OPENED BY ITSELF! WE FELL THROUGH IT BY ACCIDENT!!! WE DON'T HAVE TO TAKE ORDERS FROM YOU!!! PRINCIPAL!!!" Diamond snapped straight back, "AS LONG AS WE'RE OFF SCHOOL GROUNDS, YOU CAN'T EVEN LOOK AT US!!!"
This notion caused complete and utter silence. The only noises that could be heard was the slight mumbling of guards, getting ready to prepare the death penalty.
"Oh dear." Twilight said to the two girls, "Now you've torn it."
"What do you mean, torn it? Celestia's obviously acting like a jerk because she hasn't had any sleep at all, what with her princessy type stuff and her sun raising business. That's bullcrap! The sun doesn't need to be moved by one person, it as well as the moon, moves all by itself, not by some stuck up princess who think she knows it all and is only cosplaying as a princess to get some guilty pleasures out of being a school headmistress."
"No. No, not now!" Twilight said in shock as she noticed a dark aura emanating from Diamond as every word was pouring out of her mouth, "The paradoxes are multiplying and mutating rapidly!"
"What's going on?" Silver asked.
"The paradoxes are reaching the next stage of corruptibility." Twilight explained to Silver, "Since this Diamond Tiara isn't like the pony version, the paradoxical energy is balancing it out by corrupting her momentarily and completely altering her mood and personality."
"No-one talks to me, Princess Celestia like that!" Celestia said as she removed the cage, "I sentence you both, to death by fire!"
"What?!" Twilight yelped once Celestia subsided.
The two humans were quickly dragged away by armed guards, screaming for help as they went. The guards quickly found it to be unbearable and removed their mouths completely with a high power spell.
"Celestia, why did you have to do that?!" Twilight yelled at her, "They didn't do anything wrong!"
"Listen my dear." Her voice suddenly changed into a dark double-toned voice, "I can't let your plans get in the way of the Changelings' itinerary for Equestrian conquest."
"Changeling?!" Twilight said in shock and horror as the words quickly came back to her, "Identify yourself, Changeling!"
"Perhaps i've said too much." A pillar of pinkish light rose up around Fake Celestia, and quickly enough, her stolen body quickly disappeared, revealing an insectoid pony-like creature with black skin with holes. Its' wings and hair also had holes, surprisingly enough, but its' hairstyle was a different style and colour than the last Changeling commander that Twilight saw. This one's hair was pink and spiky, and its' tail was shaped like a pink lightning bolt. The eyes were fire red and its' mouth was bearing 4 fangs.
"Luna! Do something!" Twilight said to Luna, who was just sitting there, doing nothing.
"I'm afraid Luna cannot help you now." The Changeling said as all the fake guards quickly lost their skin and turned into Changeling Grunts, "You see, the bond between sisters is a very cherished bond. And cherished is a veritable gold mine for Changelings such as myself. It seemed foolish to pass up an opportunity to feast on such a strong bond."
"What do you want with Diamond and Silver?!" Twilight said angrily but kept her cool.
The large Changeling chuckled, "We initially had our sights set on destroying the Crystal Empire after what your sister did a few years back. But during a recon mission, one of our spies had found a mirror of archaic make and design. Even more surprising, was when two weird and tall creatures fell out of it and went with Shining Armour and Cadence. We changed our target to both of them for, how do you say it? Scientific research."
"Scientific?"
"These weird things have never been seen in Equestria before." Said the Changeling, "If we could tap into the secret of their power, we could not only take Equestria with ultimate power, but maybe even extend our reach to the things' world of origin."
"You'll never take over our worlds!" Twilight bulked up, "The real Celestia will find out about this and smite you all down!"
"Oh, Celestia?" The changeling joked before pointing her hoof up towards a green cocoon on the roof, "I think she already knows."
It wasn't long after she stopped before Twilight was blitzed by hundreds of Changeling Grunts, all of which restricting her movement and nullifying her horn's magic and her wings' feathers.
"Who are you?" Twilight said as she was being crushed on the floor by the hundreds of bug carapaces, "And i mean NAME this time, not species."
"That's right, know your enemy after all." The Changeling chuckled once more, "I am Commander Exordaks, General of the Changeling 3rd Division and right hand Changeling to Queen Chrysalis herself."
"At the very least don't hurt them." Twilight said in agony now, "They're just kids after all."
"Don't feel bad, Princess Twilight." Exordaks said as she motioned her Grunts to take Twilight away to their stronghold, "If it makes you feel any better, you'll soon be joining them."
The Grunts holding Twilight buzzed their wings vigorously and took Twilight out of the castle, through the roof. Twilight struggled and moved as much as she could to try and escape, but her sky was soon cut off by four more Grunts, all of which holding her down, preventing her movement.
"What are you gonna do?!" Twilight yelled to her captors.
"You're in no position to ask questions, you miserable little horse." One of the Grunts said back at her, "Just know that you and your little things will have a front row seat to the extermination of your kind!"
"This is in no physical way a good thing." Twilight thought to herself as the Grunts neared the Changeling Stronghold on the farthest outskirts of all pony towns.
