Rainbow factory: the phantom ruby

Scootaloo ran for her life. She was crying because of what was once her role model, now betrayer and monster said to her.

"You are WORTHLESS, you squander your gift of wings, you FAILED. ALL YOU HAD TO DO WAS TO NOT FAIL. And you FAILED. I cared about you until you failed me. Now you will be made into a rainbow."

The words hurt, as it was her hero saying them, but she needed to survive. She survived out in the everfree ever since her parents threw her out. She survived Timberwolves at 10 years old. She survived everything life threw at her, she will survive this.

Seeing a vent opening big enough for her to enter but small enough to stop rainbow, she took it.

She sighed as she heard rainbow curse as she was too big to enter. She crawled through the vents until she saw the exit across the hallway.

Leeping out of the vents, she flew at high speeds to the door as she felt a flame of hope turning into a bonfire. That was until she heard rainbow scream her name as she entered the hallway, leeping at me at impossible speeds as I almost reached the door, the flame burning bright in her, as she was tackled to the ground and everything faded to black.

Scootaloo came too inside a large room. Scaffolding above and bellow her as rainbow stood across her. Her wings where bound and chains secured her limbs as she saw what looked like a giant meat grinder was below her(1).

"It seems you finally awoke" rainbow said as employees worked feverishly around them. "You see I normally just drop the useless ponies into the rainbow extracter but you are a special case. You almost escaped, and was very determined in doing so as well. So I will personally drop you i to the machine myself. So any last words before you drop to you fate."

Scootaloo felt defiance towards the pony.. no monster infront of her. So she did her final last defiant move she will ever do.

"I hope you trip and fall into the machine you monster." Scootaloo said as the chains holding her above the extracter unlocked, leaving her to fall into the terrible machine, as it turned on, the blades moving seemingly chaotic yet intricately, the blades still wet with the blood of innocent ponies. Seeing her memories rapidly move before her eyes as her brain desperately looked for a way out of this situation despite her knowing it was no use.

As she finally reached the Machine, she didn't lose her determination, even after the blades chopped her back hooves into mince meat, drawing as much blood as it possibly could. The pain was seering as she was chopped up bit by bit. Her body being mulched as she died.

Rainbow sighed as scootaloo died in the extracter. A smile on her face, she loved making rainbows. She sighed again however, because this was the last job before the end of her shift, meaning her work for today was finished. She hated the rest of the elements, but she needed to play along. She wished scootaloo didn't fail the test however.

"We could have made rainbows together." Rainbow whispered as she genuinely cared for scootaloo, and she was going to teach her the ways of extracting rainbows from the ones who didn't deserve their wings.

She calmed down as she reached the exit as she needed a few things from the market. Some of which was crucial for the next step for the rainbow factory.

Meanwhile: in the underground of a different universe, a ruby of powers equal to the chaos emeralds (in the right hands). It sensed a person of strong will die in the face of betrayal. It had found its new master. So with the power of the phantom ruby, it did its one task Givin to it at its creation. Find a strong unbreakable soul. One that faced an unfair life with all of the cards faced against them. One who will control the powers of reality warping illusions.

(1) she knows what a meat grinder is because of gilda and her meat eating diet.

Also gilda and rainbow dash didn't seperate after flight school in this world.
