With a flash of light and an accompanying burst of red smoke, the party pony reappeared in a now much larger room. Her eyes lit up, instantly noticing that her other friends were all standing around in various states of boredom. Twilight seemed anxious, her eyes lighting up and the worry disappearing from her eyes when she saw the now demonic Pinkie Pie appear in the centre of the room.

“Oh thank goodness it went alright.” She exclaimed, trotting over to Pinkie and wrapping her hooves around the former pony’s shoulders. Pulling back suddenly, she gained a strange look in her eye. “You are alright, right?”

“Yupperdoodles!” Pinkie Pie exclaimed, squeezing her friend back while a noodly appendage snaked down the purple pony’s back and squeezed her butt. “I’m better than ever Twibooty!”

The purple unicorn giggled, magicly removing the demonic pony’s hoof from her posterior. “That's great to hear.”

Applejack nodded. “Thank goodness y'all finally decided to join us, Twi was about to have an aneurysm over there.”

Pinkie Pie smiled, noting the way that Applejack’s body had changed, growing more lithe, and feminine while also retaining that same strength and power she always seemed to have. Her fur was starkblack like the rest of theirs as was her mane, though hers had a thin stripe of green and orange running through it. “Nice horns Jackie.” Pinkie Pie complimented, pointing to the demonic pony’s newest additions.

Applejack smiled. “Thanks Pinkie Pie, yours doesn't look too bad either.”

Pinkie Pie looked up, her stark black eyes staring into the centre of her head where a long jagged horn now sprouted. “Thanks, though it doesnt nearly look as cool as yours.”

Fluttershy wiggled over, smiling broadly to the newest demonic pony. “Well I think it suits you quite well.”

“Daw thanks Fluttershy. I think you look pretty good as a slime demon.” Pinkie Pie replied.

Said slime demon blushed, her goopy form closing in on itself. “Your just saying that.”

“No way Fluttershy, it's true!” Rainbow Dash exclaimed, floating down on her membranous wings. “You look great!” She smiled widely, showing off her now razor sharp teeth, which she ran a long, snake like tongue over. “Like, really good.”

The demonic pile of goop blushed a little harder. “Oh stop it you.”

Rarity slunk her way over, smiling at her friends. “While it is true, I am rather remiss that this is going to make sewing you a nice dress quite a bit more difficult.”

Fluttershy smirked. “You say that like you aren't going to enjoy the challenge.”

Rarity tapped her chin. “True.”

“Um excuse me girls.” Twilight called out, getting the attention of her now demonically infused friends. “If you don't mind I was hoping to get my own transformation completed soon, this entire ritual is time sensitive I’m afraid.”

“Oh I’m so sorry dear. What do you need us to do?” Rarity apologized.

The rest of her friends all nodded, noting the worry on Twilight’s face had returned with a vengeance. “Ooh ooh!” Pinkie Pie waved her hoof. “Do we have to all gang bang you at the same time? If so, dibs on anal.”

“Damnit Pinkie Pie, this is not how this works.” Rainbow Dash griped, before smirking. “But if it is, dibs on that pussy.”

Rarity tutted, giving the winged demon a smack upside the head. “We may be demons now but we are still ladies, and Twilight should still be respected.” She chuckled. “Besides, everyone knows I have a standing dibs on those delicious lips of hers.”

Twilight blushed, noticing now just how closely her five friends were staring at her. “Girls, please, there will be plenty of time for that later. Right now we have to finish this.”

Fluttershy sighed. “Okay, but after this can we please fuck you?” The gooey demon shuddered. “Because I really want to be inside you.”

Twilight rolled her eyes. “Fine, but not till later okay?”

Rainbow Dash pumped her hoof in the air. “Hell yeah.”

Applejack smirked. “Whaddya need us to do anyway?”

“I just need you all to don your elements, and focus on casting the same spell we used to defeat Nightmare Moon.” Twilight grinned. “I’ll do the rest.”

Her friends all nodded, watching as Twilight summoned her magic and brought forth the elements of harmony. When the jewelry were lifted out of their case the five friends quickly realized that the objects had changed along with their bodies, and were now much different then they remembered. Though they held the same overall shape as the original elements of harmony, they were also much darker, their colors muted. Where before they appeared to be elegant necklaces, now they appeared more like ornate collars, some with spikes, and others with large black jewels inset.

The five demonic ponies shivered in delight as they felt their elements come to rest once more, fitting over the same spot they had so many times before. Pinkie Pie giggled, poking her spikey collar. “Oooh, this is way more metal then our last set of jewelry.”

Rarity smiled, striking a few poses in front of a conjured mirror. “Yes, they aren't quite as elegant as before, still, they are much more striking don't you think?”

Twilight nodded. “The elements react to changes in their bearers, twisting them as your mind, body and spirits have been twisted.” She shook her head. “But that doesnt matter, merely form a group and cast the spell, it should be enough to complete the transformation.”

“Right.” Rainbow Dash agreed, getting into position as did the rest of her friends.

The small group assembled quickly, their newly changed jewelry fitting them perfectly. With all five friends now standing in a circle around Twilight, the unicorn smiled widely. “Oh this is going to be perfect.” She announced giddily, feeling the energy already begin to build inside them.

The familiar glow didn't appear as normal, instead being replaced by a perfectly black light that was only visible due to the way that it seemed to consume the very space around it, creating a space devoid of light or color. The gems themself took much longer to charge, seemingly drawing deeper from within their bearers. Each demonic pony seemed to squirm slightly under the intense draw of their artifact, yet none complained, and no pain accompanied the drain, merely leaving a faint tickle that lingered deep in their chests.

As the light expanded it was not joined by the element of magic, which had yet to power up and seemed to have even lost some of its usual shine. The dull, normal artifact remained motionless on Twilight’s head, content to merely sit there as the dark energy built all around it.Until finally the light exploded upwards, streaking through the air before finally slamming into the grinning unicorn.

That smile didn't last long however, and as the seconds passed it turned into cry of agony before that too was blotted out by the dark light. In the absence of light her friends looked on in mixed expressions ranging from confusion, to nervousness while Pinkie Pie stood silently, a wide smile on her face.

A second later the weird unlight vanished, dashed aside by an explosion of blood red light shooting out of Twilight’s form, blotting out the rest of the light in the room and nearly knocking the demonic ponies off their hooves. They recovered quickly, their more powerful constitutions enabling them to keep standing where mere ponies would have been blown away.

They stared in silence as the light and energy began to build, glowing brighter as a cruel wind whipped about their heels. From the distance a cry could be heard, loud and keening, carried on the wings of a dark wish and brought to the centre of the room, screaming through the halls. Then a second, and a third, then a great multitude of cries the likes of which drowned out all other sound came from every direction. The demonic ponies didn't even flinch, hardly perturbed by the screams of agony that flew through the room before being consumed by the ever growing orb of light hovering where Twilight had been only a moment earlier.

When the wind itself had grown so pregnant with cries that no other sound could be heard, the light stopped growing brighter, and flashed briefly. The screams stopped, as the light pulsed once more, signalling that whatever event they had put into motion had begun to come to fruition. A third strobe and the light dulled, the creature inside beginning to be visible through the blood red light.

A fourth and final pulse sent a shockwave through the room, banishing the light, and forcing a surge of red smoke to billow in every direction. The five demons looked up in terrified wonder, their eyes beholding the sight of a being so powerful it made their very souls quake in fear. As one they bent low, keeping their eyes on the ground as the being descended to the stone floor.

“Rise, my friends.” Said a voice like whispering thunder, which echoed in the very minds and hearts of all that heard it.

The five demon ponies rose, smiles now gracing their faces. They looked up in wonder, beholding the majesty that was their friend and ruler. The demure unicorn was gone, replaced by the very picture of fury, her short, and slightly unfit body replaced by a towering monster of pure and undiluted power that now stood where Twilight had.

Pinkie Pie grinned, looking up at what had been Twilight, already wondering what new name this terrifying creature would take. She was tall, easily as tall as Princess Celestia, and probably even standing a good head above the towering alicorn. Her horn had elongated, growing sharp as it curved nearly three times the length that her original horn had, appearing as more of a scimitar strapped to her head then a true horn. Her mane had darkened significantly, nearly becoming black yet retaining a small trace of the color it once had. Her eyes had changed similarly and were now as black as pitch with only the tiniest pools of magenta distinguishing her iris from the rest of her eye.

Her tail had followed the same example as her mane, but her fur was different and was now the deepest black any being in the room had ever seen. Where her cutie mark had been was now a crown, identical to the one that now rest upon her head. The original element of harmony could be described as beautiful, graceful and even elegant, none of which could be described what it had become. It was now tall, with each point of the crown several inches of sparkling pure silver that was topped by a red gem of absolute crimson. The thin band of silver that wrapped around her head had a strange alien script inscribed into it, glowing a deep unholy light, and making terror find root in the heart of every being that looked upon it.

The mare flicked her mane from her face, sending the entire thing shimmering for a brief moment before it formed into a great mass of flowing purple and black fire. At first glance it reminded the five beings of Celestia’s or Luna’s aetherial mane, but that was where the comparison ended, as Twilight’s mane showed not the soft light of the moon or the kind light of the sun but the furious glow of the deepest pits of tartarus. Wings blacker than the night itself unfolded from her back, darkness dripping from the membranous wings as the demonic alicorn gave them a few test flaps.

With a smile on her face, the mare stood tall, her limbs cracking and popping as she forced them into position. Yet despite the fact that she had grown significantly and changed even more, Twilight showed no unfamiliarity with her limbs, moving with a grace and poise that was reminiscent of both a dancer, and a killer.

“Well girls, how do you like your new bodies?” She whispered, making her friends shiver at the mere utterance.

They all nodded weakly, unable to offer words that could compare to the magnitude of their new mistresses’. “Good, because I was hoping to make a little pit stop at ponyville before we started our little orgy.” She smirked. “After all, what's a gang bang without a few more participants?”

The girls all shared a look of barely contained glee, before Pinkie Pie suddenly leapt up and threw a hoof in the air. “Shotgun Cheerilee!”

“Damnit Pinkie Pie!” Rainbow Dash griped. “Fine, but I call Derpy first.”

Applejack shrugged. “Yall do whatever you want so long as you leave Applebloom to me.” she smirked. “And Big Mac.”

“Now that's just not fair.” Rarity pouted. “How about you get Applebloom, while I take Big Mac, then we can switch, and in return we can both enjoy Sweetie Belle after that?”

The demonic farmer tapped her chin before nodding. “That sounds fair.”

Fluttershy shuffled up beside the smiling demonic alicorn. “Do you mind if I take Spike?” She winced, rubbing the back of her neck with a goopy appendage. “I know he's your number one assistant...”

Twilight shook her head, smiling all the while. “Of course Fluttershy.” She smiled, noticing how her friends were eagerly plotting away at which ponies they would turn first. “Just remember to bring them back to the library, and do so discreetly. Until we have an army we need to stick to the shadows.”

The five demonic ponies all smiled back, eagerness readily apart in their crooked grins. “Yes mistress!” They shouted back.
