Shimmer Run 2101

"Muffin!" Derpy called out and with a quick blast of magic the Kirins Voice transformed into a muffin and fell to the ground.

"You insolent cur!" Stygian shouted as he paced toward her. "With the power of the Lunar Core I can just transform it back. I am the most powerful pony in the universe!"

"You're not powerful at all!" Derpy shouted at him as she placed herself in between Stygian and the muffin that was once the Kirins Voice.

"Stand aside or come at me!" Stygian shouted as magic streamed toward him from the Lunar Core and charged up in his horn.

"No." Derpy said calmly as she stood tall. "It's time for the wolf to shed his fleece." She looked over at Sunset Shimmer and then back to Stygian.

"You can't possibly hope to stand against my power!" Stygian warned.

"You're not powerful." Derpy said curtly.

"What!?" Stygian crackled with magic and rage.

"This whole time you've silenced Sunset; you've isolated her; you've broken her; you've controlled her and made her do things she doesn't want to do. You've taken her away from the ponies who love her." Derpy lectured angrily.

"But I love her!" Stygian protested.

"If you really loved her you would have let go the moment you realized your tight grip on her was causing her pain. But you don't because you're an abuser"! Derpy looked over at Sunset who stood with a forlorn expression.

"Absurd!" Stygian fired a blast of magic at Derpy, knocking her down. Sunset Shimmer winced as she watched Derpy writhe in pain.

"Your little sad pony act might fool others but it doesn't fool me. You don't hold on because you love Sunset. Even with all the magic in the universe you are powerless- you are a slave to your fear of the well-deserved, miserable, lonely and pitiful existence that awaits you the moment you loosen your grip." Derpy taunted as she pulled herself back to her hooves.

"Enough!" Stygian screamed angrily as he unleashed an even more powerful blast of magic. Derpy fell to the ground and writhed and wailed in agony.

Sunset Shimmer began to shudder and sob as she watched the spectacle unfold.

"She's right..." Sunset Shimmer said with one last sob as she stood tall and started channeling energy into her horn from the Lunar Core. "Get out of my life!" Sunset unleashed a powerful blast of energy at Stygian- knocking him back.

"Everything I've ever done has been because-" Stygian fired back at Sunset Shimmer who met his volley of magic with an equal one of her own.

"I never asked for any of this!" Sunset Shimmer began to glow red as the walls of the pit started to shake violently.

As the couple became entangled in their magical duel their grip on the others lifted.

"They're too evenly matched. This fight will rage on for eternity at this rate!" Discord warned.

"An take out all of pony kind along with it..." Applejack said with a sigh as boulders started raining from above.

"Our powers are equal!" Stygian warned as he and Sunset Shimmer began to levitate in front of the Lunar Core. "Your friends are right. Let us tame this power together for the greater good." The two met each other with another stream of magical blasts.

Sunset Shimmer turned and met Derpys stare. Sunset was channeling her blast at Stygian; Derpy was hastily turning falling boulders into harmless muffins. A tear came to both of their eyes with a nod of understanding. A sphere of magic enclosed Sunset and Stygian and they began hovering toward the Lunar Core.

"Sunset, what are you doing!?" Rainbow Dash protested and attempted to fly toward the scene but Trixie held her back with a stream of magic.

"Trixie doesn't want to lose you too!" Trixie said.

"You'll kill us both!" Stygian called out.

"And then nopony else." Sunset said with a tearful whisper as the couple collided with the Lunar Core. The core began to pulsate violently and the air rippled with searing heat.

"We have to get out of here!" Discord said. He quickly snapped his fingers and the rocket caravan appeared at the bottom of the pit.

"Everypony in!" Trixie ordered.

Everypony quickly filed onto to the caravan and no sooner than they launched did the Lunar Core explode into a burst of energy. Arcs of lighting and plasma chased the caravan toward the surface of the moon. The moon quaked as the caravan escaped the lunar orbit and set course for Equestria.

"I guess they're together on the moon forever now." Derpy said as she looked out the window at the moon and watched as the red glow from the explosion of the Lunar Core faded to grey.

"Well uh, technically ah saw Stygian fall in first." Applejack said.

"So you mean Sunset died a widow?" Fluttershy asked woefully.

"Eeyup." Big Mac agreed.

"Well I then suppose that satisfies the prompt." Discord pondered.

"The what now?" Applejack quizzed.

Trixie walked over to the window and looked back and a tear came to her eye. "Sunset..." She began.

"Here we go again." Discord sighed as he pulled out his phonograph and started to play tragic music.

"Really? Another tragic back story? Didn't you already have two of those?" Rainbow Dash protested with a roll of her eyes.

"Yeah, uh, no offense sugar cube, but it's been a long day an' well ah'm thinkin' it be a might' bit nice if we could end it on a high note for once." Applejack said.

"Ooh- I know! Let's end it on a freeze-frame!" Discord suggested.

"A what?" Rainbow Dash asked with a tone of skepticism.

"Just say something inspirational and everypony jumps up and cheers." Discord explained.

"Trixie isn't finished-" Trixie began complaining.

"It's time to go run all the Osees out of Equestria!" Rainbow Dash interrupted as everypony jumped up and cheered as the caravan streaked through the sky like a shooting star.
