The Crystal Empire had been mostly peaceful since Sombra's defeat, the Crystal Ponies were living great lives with new ponies coming in almost daily. As Twilight (Still in her flaming true form) and her friends stepped off the train to the Empire, everypony gave them only brief, strange, looks before returning to what they had been doing.
"They don't seem to mind, then again, it's not the first time Changelings have entered this place." Twilight said through the Localized Hivemind.
"What-ever, we still need to speak with Cadence." Rainbow said.
The group continued in relative silence as they approached the Crystal Castle and knocked on the door. Two guards opened the door, quietly, to allow them in.
"We wish to speak to the princess." Twilight said.
"As you wish." the guard said as they turned down a corridor.
The castle was about the size of Twilight's own with everything made of a form of crystal. A few staff ponies, including Changelings, walked around with treys of food, cleaning supplies, or anything else one would need as a servant. The group entered a hall that anypony would recognize. The hall was lined with stained glass windows showing important events in history. Rainbow smiled slightly when she saw the window depicting her with the crystal heart as she flew past Sombra to return it to its proper place.
"We're here." the guard said as he stopped.
"Thanks." they entered the throne room then. Cadence was siting on her throne with Shinning's currently empty, Twilight asked Cadence where Shinning was.
"Prince Shinning Armor left on a call from Princess Celestia concerning somepony breaking ancient laws like using forbidden magic." Cadence said.
Twilight hissed before speaking "How cruel of Celestia to send Shinny to kill his own little sister simply because she, being the most powerful being yet according to Celestia herself, wanted to test her limits."
"Wait! Twilight is the one that did that, but she would never go against Celestia."
"I assure you that I have." Twilight threw up her original disguise then, though it was her flaming form.
Cadence just stared, noling, and there had been plenty that tried, had ever been able to match Twilight's fire form, something Cadence had learned about the hard way. "Twilight? Why are you a Changeling?"
"Ask Celestia, she's the one that cast the spell to turn me into a Changeling and give the illusion of a new Alicorn, similar to what she did to you."
"What? Aunt Celestia would never do that."
"Really, she did it to Vinyl Scratch, to my own guard captain, to you, to me, and even to Clover. Don't you find her execution for 'impersonating Clover Leaf' to be a little too well timed in comparison to her intended meeting with you?"
Just then, Shinning came in. He looked at the fiery Twilight and instantly erected a shield to protect from her powerful magic, in-case she attacked as she had several years ago.
"Took you long enough Shinning, I was just getting to the point where I'm sure you'd be needed. Tell me though, have you ever memorized Cadence's magic signature, the only thing that can't be altered with any form of magic?"
"Of course I have." Shinning said with hurt in his voice, likely from the natural malice in Twilight's voice when she was in that form.
"Good. Cadence, if you want my proof then here." Twilight cast the advanced reveal spell then and aimed it at Cadence, revealing Cadence's true form.
Cadence's carapace was dark pink with a saddle carapace the same color as she originally had for a coat; her mane and tail retained their colors but were silk-like and had several holes in them; her horn, like Twilight's, had a few holes in it; her hoofs had holes in them; she had fangs like those of a bat-pony's; and her wings were of a Changeling Princess' and, like Twilight's, held the former color of her coat, except in Cadence's case they also faded to purple near the tips.
"What?" Cadence asked as she stared at her self.
"The spell I just cast is an advanced reveal spell, it's needed to reveres the advanced disguise spell you were under." Twilight dropped her disguise after saying that.
"Huh?" Shinning was utterly confused now.
"Basically, Celestia uses the True Metamorphosis Spell to give the illusion of turning a pony into an Alicorn, she also uses the Advanced Disguise Spell to make them look like Alicorns, She does this both to increase public image and to be able to stage a replacement and execute the Changeling should they learn her secrets." Midnight clarified.
After an hour or so of explanation Twilight took her got up to leave.
"So where are you going now?" Cadence asked, she hadn't bothered with putting her disguise back up.
"To pay a Sun Goddess a little visit." Twilight said, even after an hour of talking peacefully, she was still in flames.
The doors to Celestia's throne room were blasted open by powerful orange magic as Twilight, in her Harmony armor, which had changed to accommodate her new appearance; Midnight, in her personal armor and with a set of wing-blades strapped around her wings; Scootaloo, in her Night Guard armor with her sword floating near by; Aurora in the bright white armor she apparently had and with a sword; and Rainbow Dash, in her own Harmony armor ad Wing-blades burst in.
"Sister, what's going on?" Luna asked from Celestia's right.
"I'm being over thrown." Celestia said as she un-sheathed a golden sword with a sun emblem on the hilt and stood to fight.
Twilight spoke first "I can't believe I ever looked up to you Celestia, all the lies and deceit and I never saw them, now you'll be scorched by the Fires of Harmony."
"Stand down Changeling."
"So Luna doesn't know then, you mean to tell me that you wont even tell your own little sister that you've secretly turned me and Cadence into Changelings to give the illusion of turning us into Alicorns, you could have just as easily cast an advanced disguise spell on us to give the illusion."
"What is she talking about sister?" Luna asked as she looked at Twilight.
"I'm Twilight Inferno, the fire within Twilight Sparkle, and I'm here to bring her secrets to light and destroy her power over this land."
"But, what are you talking about?"
Twilight closed her eyes as a powerful rainbow energy began swirling around her body, the elemental symbols on all the Harmony Armors glowing brightly. Twilight released the spell and let it slam into Luna with full force, Luna then held her head while fighting off a major headache. "And that's with just one other element near me."
"Make it two." Fluttershy said as she flew in through a window with her own armor on. Her armor was gold with a metallic gold head band around her head and a butterfly in the center of the headband, chest, and hoof shoes. Fluttershy had a set of wing-blades on, a golden sword in each of her hoofs, and one in her mouth.
Celestia narrowed her eyes. "The Five Bladed Shy." she said angrily.
"It's The Five Bladed Bat now, and I'm not alone." all shyness was gone from Fluttershy's voice.
Fleetfoot, in armor that held the same color scheme as the wonderbolts uniforms and with a set of hoof-claws on; Spitfire in similar armor with a sword that had a fire design in her mouth; and a pony that looked like Flutterbat, but was Nightshy in full Night Guard armor with a set of wing-blades, and a set of hoof-claws all flew in threw the recently smashed window.
Celestia looked over each pony, stating their well-known nicknames. "The Nightly Wind, The Fire Phoenix, and The quad-blade Bat... where's The Vengeful Spirit?" she asked.
"Right here." Midnight said as she spread her wings out wide, using small amounts of Dark Magic to keep airborne, she had read about the nickname in a letter she had found in the room with Clover's diary.
"Hey!" Aurora said as she flew right in-front of Celestia. "Are you forgetting about me, The Dead Spectrum? I might be a filly, but I'm still part of the Spirit Clan and I'm still well known!" she yelled as she flew back to her original spot and placed both hoof's on her sword before splitting it in two, both halves holding the white tint that symbolized a pony with the natural ability to see the magic signature of others.
Twilight struck first, moving in from the side and slashing Celestia's side. Fluttershy was next, delivering five cuts in the form of a pentagram. Aurora stood off to the side with large amounts of Black Magic swirling around her in a cloud. Scootaloo flew in with a Lunar charged cut across Celestia's face.
"Come." Nightshy said as she flew over to Midnight and then flew her back to Fluttershy and Spitfire.
"Time to relearn a bit of you life." Fluttershy said.
Aurora was in darkness, literally no light could escape the Black Magic's hold. She didn't see anything with her normal sight, but she did see the different colored outlines that represented the magic signatures of those around her. Rainbow Dash was about four feet to her left and ten feet above her, she had a strong rainbow colored signature, the signature was moving in a circular motion around her. Twilight was slicing at the large golden signature that was Celestia, but Twilight's signature was about twice as large and held an orange fire design. Fluttershy, Nightshy, Midnight, and Spitfire were all in one place. Fluttershy's signature was a calm pink with little movement and was about as large as Twilight's and Rainbow's (Likely from them being Element's of Harmony. Nightshy's was light blue with a calm waving motion. Spitfire's was the color of fire and shifted from calm to erratic every now and then. Scootaloo's was silvery blue with a similar movement pattern to Nightshy's, though a lot more erratic. Fleetfoot's was the color of ice and misty like something that was extremely cold. Midnight's was the most interesting, it had been slightly recolored through a lot of training and practice, which was all that could really change a signature other than a powerful event, her signature was black and white with a faint grey tint in some areas, the tints were in the shape of a bat and were what had been faintly altered to make ponies that saw her signature know who she was. Aurora looked down at her own signature, hers was thinner then the others and moved like a storm, the coloration was red. Aurora was finely ready, right when the signatures of her family started moving in at four different angles, she unleashed all the black magic around her and shot upwards.
Celestia was blown through a nearby wall from the powerful team move the Spirit Clan had performed. Rainbow met her on the other side with a punch that's speed and force had been increased by a sonic rainboom. Celestia groaned as she slowly stood up.
"Where did that little brat come from?" she asked herself, thinking of the filly that had delivered the blow that sent her through the wall.
"You mean me?" Aurora asked as she flew in, both her swords now having Black Magic flowing off them, with the same occurring in her eyes. Aurora Light shot forward then and cut clean through Celestia with her twin swords, stopping a few feet away and looking at the badly wounded Alicorn. There was a lot of rainbow colored blood on her coat from the attack, but Celestia still stood. Twilight Inferno, Fluttershy, and Rainbow Dash flew in then, Scootaloo was no where to be found. Twilight's sword ignited in bright flames as she shot towards Celestia, cutting through her and spilling even more blood. Celestia angrily stood up and released a powerful explosion of magic, sending everypony there into the walls.
"I'm tired of this." Celestia released several blasts of magic at her captives. None of the blast made contact as a blue shield blocked them. Celestia turned to see Scootloo standing on top of Luna, who was now awake and very mad.
"I UNDERSTAND ALTERING MEMORIES TO HELP COPE WITH SOMETHING, BUT TO ALTER MY MEMORIES JUST TO ENSURE I'D CLING TO YOU IN HOPES OF GAINING FORGIVENESS YOU DIDN'T DESERVE, THAT IS JUST EVIL." the Lunar Princess yelled in the Royal Canterlot voice. Luna's magic swirled around her at an immense speed then and, with Scootaloo lending extra Lunar Magic, she unleashed it on Celestia.
When the smoke cleared, Celestia was weak, but she was still breathing. Twilight approached darkly and spoke to Celestia.
"As I said in the beginning, you'll be scorched by the Fires of Harmony." five streams of rainbow colored energy flowed from each of the element bearers, swirling around Twilight chest before she looked at Celestia. Celestia let out a pained scream as rainbow colored flames engulfed her. When the fire died, she was dead. "She had too much evil for Harmony to save her." Twilight said as she spun to face Luna, Midnight beat her though.
"Princess Luna, Chrysalis, formerly known as Crystal Bliss', Hive has split in two. we need Chrysalis and her Venom Hive to come and aid us as the Poison Hive, now lead by a vengeful Changeling, is planning to attack." she said.
"Got it." Princess Luna said.
