Celestia covered a yawn with her hoof as she crawled atop of her bed, flopping down against the mattress after the long day of royal duties. She fluffed up her pillow and buried her muzzle against its downy softness and entered into a deep sleep right on the spot. A sinister chuckle rumbled out from the curtains, emitting from Starlight Glimmer as she trotted out confidently.  Starlight approached the regal bed, Luna following behind with that large equal grin.

	“My, your poor big sis.” Starlight cooed out as she pulled back the covers just a little, showing off Celestia's bright sun cutie mark. “Still shackled by her silly cutie mark. But now that her loving little sister has discovered the truth, we'll soon fix her up. Wouldn't you like that, my little Luna?”

	“But of course, Mistress Glimmer.” Luna replied in a whisper as per Starlight's orders. Luna's body was rigid to attention, her mane having stopped its continuous flowing after a few days in her new life as an equal pony. Luna of course happily let Starlight style it to a cute curly pigtail that hung down by her cheeks. Her dark purple flanks that once bore a majestic moon now only bore a glossy ink black equal sign.

	“Now, my little Luna, you remember what to do?” Starlight prodded, standing before Luna. Luna beamed out with her blank featureless eyes eagerly.

	“Yes, Mistress Glimmer! Thank you for letting me help bring my sister to the truth!” Luna stated almost too loudly. Starlight's eyes narrowed and she planted her hoof firmly to Luna's maw.

	“Silence, you don't want to ruin the plan!” Starlight scolded, making Luna kneel down a bit to try and appease her Mistress. Starlight let the transgression go and turned back to the true matter at hoof: conquering Celestia. Starlight's tail flicked to motion Luna to the other side of Celestia's bed. Both their horns began to glow, though Luna's magic had been getting exponentially weaker. Starlight knew this would happen and didn't really expect Luna's magic to do much of anything at all. It was really more about subtle symbolic domination, of having the younger sister “help” in bringing down the older, trying so very hard to strip her own older sister's power. This will be delicious to watch~

	In her dream, Celestia was trotting toward the horizon, her long multicolored mane flowing endlessly. She paused to gaze towards the night sky as Starlight and Luna materialized into a bush out of earshot behind Celestia. Starlight smirked as she leaned in towards Luna as if to whisper, but instead she sent her magic reeling thru into Luna's unprepared brain! With a stifled gasp, Luna's eyes widened only briefly before their light flickered away, her memory having been rewritten.

	Luna found herself outside with her sister just standing there, gazing with a relaxed air. Just before Luna could move, her eyes widened at an eerie sight: the sun was rising from the skyline all without Celestia's magic! Luna stood flabbergasted at the sight, giving Starlight ample time to just slink in to whisper with a sultry tone.

	“You see, I was right all along, little Luna. Your cutie marks were all lies. She deceived you all along, your own sister herself lost to this cutie mark facade.” Starlight's voice dripping like morning honey, oozing into Luna's ear as easily as melted butter.

	“I... I see the real truth...” Luna whispered back, her equal cutie mark giving a very strong pulse of its glossy blackness against her flank as it sealed deeper into her very essence. Starlight pressed her hoof to Luna's long horn, pushing against it firmly to cause Luna to shake and obediently close her eyes, falling into a limp trance. Starlight had learned her lesson back at her old town – she needed to make sure her equality grip was far deeper than just a mark on the flanks of ponies.

	With that out of the way and Luna not paying attention, Starlight turned her attention back to the unsuspecting ruler. A devious smirk played upon the unicorn's muzzle as she oozed her magic from her own, which snaked its way over to Celestia and played about with the royal's flowing long mane. The tip of her magic brushed just underneath Celestia's ear before oozing inward.
	“Naturally, without any power. Just watching it rise like everypony else.” Starlight's voice wormed its way through her magic into Celestia's mind. Celestia fidgeted a bit, though Starlight's powerful magic hushed Celestia's inner voice. Making Celestia feel like this new voice was her real inner voice. “Feels so much better being just like everypony else. To give up this silly cutie mark facade. To be equal to everypony.”
	Celestia managed to shake her head, though her ears rolled back submissively. She gazed back up at the sun, which started to dim, a large oily black equal sign oozing onto its surface like ink spilling from a bottle. Celestia stared up at it, Starlight implanting a great driving urge to be part of equality, making Celestia feel weaker.
	The princess's long legs shook weakly, feeling her chest tighten as she panted. Her heart raced as her sweat tickled down her white hide. Starlight giggled to herself as she concentrated more magic, bombarding Celestia's inner psyche. Celestia felt a shaking to her very inner core, letting out a hot sweating cry as her sun cutie mark morphed into a thick deeply-ingrained equal cutie mark, tears rolling down her cheeks as she screamed!

	Celestia gasped and flew from the bed, her breaths coming in deep gasps. She felt every drop of sweat upon her body, her wings sticking straight out like boards. Her eyes darted all about her empty room, feeling like her heart was trying to escape from her chest. Quickly, she flew off the covers and checked her cutie mark – still a bright sun. She sighed out and brushed off the sweat collecting on her forehead.

	Starlight took the limp body of Luna in her magic and quickly trotted outside, heading for the balcony for another pounce on the sun princess. She awoke Luna quickly with a shake of the former moon princess. Luna murmured a bit, being brought out of that particular trance, though still believing what she saw was true.
	“M-mistress Glimmer, I-” Luna started to say, but Starlight shushed her by placing a hoof to her lips.
	“Shush, my child, I know. You were so shocked, you fainted the whole day away.” Starlight said to lampshade the fact it was still night. “But now, we don't have to worry about my plan anymore, do we?”
	“Of course, Mistress Glimmer! Thank y-” Luna began to say before Starlight shushed her again, no longer needing to reinforce the now truly gone princess. As just then, the real prize stepped into the scene.
	Celestia took a deep breath of the fresh air, gazing up to the twinkling stars. Her mind still remembered the odd nightmare. She could still swear she felt the deep inky black equal signs upon her white flanks. Could feel them pulse that eerily deep sameness into her core, making her feel... She shook her head sharply and let out an exasperated sigh. Maybe her sister could help interpret the dream? Wait... where has Luna been? She just realized Luna had been missing for a few days without a word, making Celestia have to take back over. At first she figured Luna was on another of her usual sprees of exploration, but... Celestia turned around to search for her sister, only to find Luna right behind her. 
	“Luna, there yo-... what happened?” Celestia asked, noting Luna's dull colors, different mane style, and wide creepy smile. “Um, sister, are you alright?”
	“I'm doing better than I ever had before, sister!” Luna stated as she stood erect. “And now, you can join me in the truth!”
	“The truth?” Celestia asked half-heartedly, her mind racing as to what might have happened – but then Luna turned happily to show off her deep dark equal sign blazoned upon her flank. Celestia recognized it from her dream and started to back away, only to bump into another pony. Thinking it was a guard, she turned to give an order – only to be blasted into her eyes by Starlight's intense magic. Celestia's body froze with a raised foreleg, her maw falling slowly agape as Starlight's magic flooded the princess's eyes, oozing out and trickling into her ears next.
	“I see you remember my symbol of equality.” Starlight's voice resonated into Celestia's brain. “Did you love that version of reality, my vision for everypony? Don't try to deny it; I remember your blush quite well.”
	Celestia's wings shook lightly as she tried to resist from inside, but Starlight had gotten too much of a hold to be pushed so easily away. Starlight laughed sinisterly, quickly making sure to block access to Celestia's horn before motioning Luna over. With the same large creepy smile, Luna trotted over to her captured sister.
	“I'm so glad you'll be with me, sister. I can't wait for your smile to match mine, then we can help the rest of Equestria join us!” Luna said like a good drone. Celestia wanted to talk some sense into these two ponies, but Starlight had kept that mouth shut. “You should let Mistress Glimmer take your silly sun mark away, especially since we both know cutie marks are unnecessary for true happiness. You don't need the silly thing and it only makes every other pony feel oppressed. Surrender the monarchy, dear sister, let Mistress Glimmer rule with equality for all!”
	“That's enough, my dear Luna.” Starlight said with her wicked smug smirk. She stepped forward, her magic sending out a bulbous ball of extra energy that squeezed against Celestia's ears lewdly before popping in, making the princess's eyes roll up and her maw to gape in a silent gasp. The feeling was like an electromagnetic pulse just hit her full on, buckling her elegant knees. Her thoughts became scrambled and disjointed briefly, making Starlight's voice even stronger, more in control. Thus Starlight began her beautiful mantra, each sentence augmented with smaller bulges that pulsed and disjointed any other thought that did not conform.
	“In sameness, there is peace. Exceptionalism is a lie. Free yourself from your cutie mark.” Starlight's magic continued undaunted, thudding hard against Celestia's weakening will. “Choose equality as your special talent. Difference is frustration. To excel is to fail. Be your best by never being your best. Conformity will set you free. Accept your limitations, and happiness will follow.” Starlight's magic fattened as time went on, straining against Celestia's ears before popping in with a lewdly wet sound. Celestia's legs shook weakly, drool oozing from her huffing maw. Starlight stepped closer, gliding a hoof to Celestia's head and pushing down. “You're no better than your sister.”
	Celestia's legs finally collapsed along with most of her psyche. She tried to wobble back up, a little bit of Celestia still somewhere inside that wrecked mind. Then a hoof planted onto her back, stepping down and keeping her to the ground – but it wasn't Starlight's. Celestia's head shook weakly in its state as she tried to look behind her, although she knew what she'd find. Luna's blank muzzle-wide mindless smile met Celestia's eyes, Luna's leg planted firmly to Celestia's back. Celestia could feel that Luna wasn't using a lot of force – just a regular amount. Yet, her entire being felt weak. Her body, muscles, her mind itself feeling loose. Utterly dominated, too weak to even push off her conquered sister, knowing she was next to end up just like Luna.
	“No more responsibilities. Finding true happiness in being one with everypony.” Starlight continued undaunted, her voice both smooth and firm. Celestia's mind faded weaker and weaker, and it didn't help that she knew it was going to happen, that the outcome was inevitable. That she was being defeated right here, right now. Starlight's magic began to manifest around Celestia's cutie mark.
	Celestia let out a shaking groan, feeling her cutie mark getting pulled onto, but not off her – rather, into her flanks! The sensation was unlike anything she had ever experienced in her entire life, and a part of her was embarrassed – it was so good! Maybe... maybe this unicorn was right.
	“Of course I'm right. Everypony should be equally servile to me. You should be just like them, free of worry and hurt.” Starlight's voice dripped into Celestia, taking over and purging all other thoughts. Celestia nodded softly, her eyes fading as her cutie mark slowly disappeared inside of her, glowing from within. With a pull of her head, the glowing orb that contained the powerful sun cutie mark moved up through Celestia's body, pulsating up into her belly.
	Celestia couldn't believe this intense new deep feeling nor even begin to describe it as her cutie mark was pulled along from inside, with the sensation of all her magic and essence and individuality being absorbed into the glow of her own cutie mark – a very stiff shake rocking through her once majestic frame as it passed her heart, stealing what little was left. Tears rolled down Celestia's dull muted gray cheeks as her smile grew, fully conformed and aching for its sweet release, to be free and equal! She arched her back and rolled her muzzle up towards Starlight, now helping to be rid of her once powerful essence. Her maw reflexively closing as it felt the large lump of her cutie mark at the back of her throat.
	Starlight giggled out with a smug smirk as Luna clapped her hooves. The glow was much brighter now, oozing up Celestia's neck and protruding lewdly against the skin. Celestia's large wings flapped erratically before going stiffer than steel. Celestia's mouth slowly rolled back open, a pink rose blush across her muzzle when her cutie mark brushed against her tongue. With a faint moan, Celestia “voluntarily” opened out her maw, betraying her cutie mark and letting it go to its rightful place.
	Starlight eased the glowing sun mark out and away, floating it into a jar and sealing it tight. The victorious unicorn smiled softly as she tapped her hoof. Both Luna and the new and improved Celestia stood to attention with beaming large empty smiles. Celestia's flank now bore faint black equal sign, which stained darker and darker with each passing minute, pulsating its brainwashing equality straight through. The process of taking the cutie mark through the inside made it much easier and quicker for the equality to brand itself upon the once powerful alicorn. Starlight looked over the dominated duo before clopping her hoof twice. The unspoken command hit the two former princesses, who eagerly started to recite the addicting equality mantra together.
	“In sameness, there is peace. Exceptionalism is a lie. Free yourself from your cutie mark.” Their voices rhythmically matched each other in their mindless obedient droning as they continued on. Starlight trotted out of the room, closing the door behind her and sealing it with a spell as the sisters kept repeating the mantra over and over. Starlight took a big breath, wiping the seat from her bow that she had been holding in – that was the most powerful brainwashing spell she had to pull off! She gazed at the cutie mark inside as she rested just outside to make sure guards didn't wander inside. She shrunk the jar down to hid it into her mane, taking her rest as she knew an even harder task was before her – bringing up the sun for the other ponies to not raise suspicions.

	Starlight stood atop the royal castle in Canterlot, Celestia's cutie mark still right inside the jar, though the lid had some holes poked through it now. She gazed to the sparkling stars, before concentrating upon her horn. Celestia's cutie mark pushed upward, smooshing a bit against the lid. Faint smoke-like tendrils of sparkling pink oozed through the holes and coiled around Starlight's horn, intensifying her magic. Her face flushed and she groaned, eyes clenching tight as her body started to shake as she reached for the sun. The sight must have aroused some ponies, she was sure, as the sun wobbled upward at a snail's pace.
	Starlight grunted, sweating across her muzzle. She pulled harder at Celestia's trapped essence, straining the cutie mark harder against the lid. Starlight stomped her hoof to the roof, leaning forward as she tried to control her growing panting. Her face flushed in a strained blush, the former magic of the princess helping the almost impossible task. Once the sun was in its proper order, Starlight plopped with a big gasp, her right hindleg twitching out. She lay there, a lot taking out of her.
	“I'll have to move onto the masses sooner then planned...” Starlight muttered to herself.
	“Very impressive.” A voice suddenly said. Starlight shakily tried to shoot up to her legs ad twirl, only making her dizzy after her sun-rising spell. A hoof-full of changelings hovered around their queen, who trotted closer. “I should thank you for taking them down for my little minions.”
	“H-how-” Starlight started to say, though her voice was still hampered by her panting.
	“Oh, don't be too suprised. Ever since our defeat at the Crystal Empire, I've been rebuilding my adorable minions bit by bit, salvaging the love of the siblings. Once you took their marks and identities away, the sudden drop of love power was hardly unnoticeable.” Chrysalis stated in a matter-of-fact tone. Starlight grimaced and braced herself, her horn sparkling weakly.
	“Now, I had thought briefly about a diplomatic tie with you, as sorts. But a civilization of equal dull love? That won't stand the test of time. Ironic that now I will be saving those silly ponies. Ah well...I'll get over it.” Chrysalis stomped her hoof and her changelings swarmed around the weakened Starlight. The cutie mark jar flew out from the fray, letting Chrysalis catch it in her own green magic.
	“Don't be too harsh now, my little minions. The princess of friendship wouldn't take too kindly to us if we teach her new friend some lessons without her tutoring.” Chrysalis trotted back inside, purposely taking her time. The sisters wouldn't remember anything anyway, so why not enjoy this little moment? Besides, it'd be fun the see sun and moon bowed low to one of their own subjects for a bit. A sly smirk crossed Chrysalis' maw at the idea of toying with the corrupted sisters for at least the night... or two.
