"Celestia, Luna…give up. Even with your incredible might, there is no stopping us. For now, it is our time…it is our time to rule Equestria." the violet mare commanded, her voice ringing and orotund. They continued to walk forward, and wherever their hooves fell, the earth died.
"No," The Sun's voice boomed. "We will not back down. We will continue to fight, no matter how powerful you claim to be. If any one of us should give up, it should be you! You have no idea the magnitude of what you're about to do, Twilight Sparkle! Please, for the safety of yourselves and of Equestria, you need to see reason!" She cried, extending her massive, grand white wings. At this, the Six halted in their tracks, the intense, burning gaze of Magic trained on The Sun.
And for a moment, everything stilled. The two sides, the Six and the Sun & Moon, were completely and utterly motionless. In the distance, a whit hot bolt of lightning flashed across the blackened sky, followed by a clap of thunder; the dry, hot wind kicked clouds of dirt and dust across the barren landscape. Magic continued to focus intently on The Sun, mentally weighing her words. Her gaze was so powerful that The Sun could feel it burning, boring a hole into her skull. Still, The Sun stared straight back into Magic's amethyst eyes, which glowed and pulsated with arcane energy. They remained that way for what seemed like an eternity, two of the most powerful beings in Equestria locked in a contest of staring. That is, until finally Magic closed her eyes. It seemed like she had successfully diffused Magic, and for a moment, she was filled with relief. But then…Oh, no.
Alarm flared in The Sun's mind as the rest of the Six shut their eyes as well, all in unison. And all of a sudden, it seemed as though the very foundations of the planet were quaking in fear of what was coming. Magic's mouth began to move; it began as nothing but a whisper, and in that moment The Sun was certain that her words had fallen upon deaf ears.
"That in the spirit, and fire, and the earth and the water, come unto me, disharmony."
The wind began to pick up, and the thunderstorm grew closer, the claps and booms becoming more frequent. Magic's voice grew louder, seeming to come from everywhere and nowhere at once, filling all of the empty space around them, invading The Sun's mind.
"No…" The Sun breathed, tears gathering in her eyes, her body already beginning to burn with pain.
"From Tartarus, where the demons roam, come to me from your unholy home.
Let me reign in chaos and insanity. Come unto me, disharmony.
Devils, spirits, and magic of all kinds- submit to me, for you I bind.
This is my will, so mote it be. Come unto me, disharmony!"
The Sun and Moon screamed in strangled agony as they fell to their knees, weapons clattering to the ground as they clamped their hands over their bleeding ears. The voice of Magic, the incantation she spoke, was not meant to be heard by anyone other than the caster and the dark spirits they summoned. The Sun was beyond terrified that Magic even knew that spell. It was a thing of pure evil, and with Magic's powerful arcane ability…she screamed once more, and she could feel her throat tearing with the pure force of it as she did so. She screamed not only for her physical pain, but for the mental and emotional trauma she was experiencing. It seemed like just yesterday she was meeting the bright, beautiful, sweet, starry-eyed filly Twilight Sparkle for the very first time, although it was countless moons ago.
"Princess, I'm so sorry!"
"Its okay, Twilight. You know, Iv'e never seen a Unicorn filly with as much magic talent as you, Twilight. In fact, I would like to make you my star pupil."
Now, her star student, her daughter- that she was once so proud of, not to mention all her wonderful friends- was turning into something unspeakable.
And through the tears, through the dust in her eyes, The Sun could do nothing but watch as the spell wreaked havoc on the Six. Black, deathly tendrils began to push out of the earth, writhing and coiling in the air in a macabre dance of death. It was pure, unholy dark magic. There was nothing more powerful, and nothing more deadly. Magic smiled, and The Sun gasped. Already, her teeth had become deadly fangs, like that of a hydra or manticore. The dark magic reached up, and began to wind itself around the Six. From the hooves up, wrapping them in airtight magic cocoons. The noticeable transformations started soon afterwards, beginning with Honesty.
Honesty screeched loudly into the night as a pair of leathery bat wings began to push out of her back, covered in blood and flesh. Her nails began to fall out, one by one, and were replaced with menacing claws. Her teeth began to morph and change into fangs like Magic's. Then, a bloody line appeared on her forehead as her mind's eye opened, tears of pain welling in her other eyes.
The transformations continued, one by one, from Honesty, to Kindness, to Generosity, to Laughter, to Loyalty, and finally, to Magic, until they all were nothing but demons, harbingers of darkness and chaos.
Despite how much she didn't want to believe it, The Sun knew in her heart that the Elements of Harmony were long gone. There was nothing of what used to be now, nothing of the sweet mares that would have gladly given their lives to protect what they were now destroying, burning and crushing until there was nothing left. And there was nothing that The Sun or Moon could do to stop them.
Equestria was forever doomed.
