In loving memories

"I guess it's my turn now." Another familiar voice rang in Starlight's ears. The tall, white alicorn walked into the dark room.

This time, Starlight didn't fear her. She expected Celestia to give her a talk or something about what she did wrong and walk away, like Moondancer did, but kinder.

This was far from the truth.

"So... Starlight Glimmer." Celestia spoke. "I really had high hopes for you. Being Twilight's pupil and after all you had been through."

"Wait, how did you-"

"I can watch your past. It was... intriguing. But I allowed you to be her pupil. After defeating Crysalis, I thought you had finally changed and I could make you into a princess." Celestia frowned. "But it looks like I thought wrong."

Celestia levitated a small but sharp scalpel, playing with it.

"You have killed the princess of friendship and 4 of the elements of harmony, which in turn ruined many lives, just to prove that friendship isn't magic. Just look at the title of the show of my sake!" Starlight looked puzzled.

"Anyways... I also haven't punished you for ruining several alternate universes and enslaving an entire town of ponies to get 'True Equality', so I am long overdue." Celestia smirked as she twirled the scalpel.

"After looking into several alternate universes myself, one universe intrigued me. I'd never thought Pinkie Pie, the element of laughter, could be that... merciless to Rainbow Dash." Celestia readied her scalpel. "I took inspiration from her for this very moment. SAY GOODBYE TO YOUR CUTIE MARK!"

She stabbed the scalpel into the side of Starlight's cutie mark. Starlight cried out in pain, but couldn't move after the effects of the crystal impalement. Celestia carved out a circle around the cutie mark as Starlight weeped silently, knowing she couldn't do anything.

Celestia pulled out the cutie mark with her hoof and placed it on the bloody stone floor. She moved on to the next one.

She noticed Starlight was not screaming anymore. So she took an even more painful approach.

Celestia made a semi-circled slice around Starlight's cutie mark.

"Hey Starlight, think fast!" Starlight couldn't respond before her cutie mark was brutally ripped apart. Starlight screamed loudly. Then she cried.

Lifting up her detached cutie mark, Celestia said, "A cutie mark, a pony's soul, is what makes them unique, and you tried to remove all that. Now being cutie-markless, you will feel how it's like to be equal, how Twilight felt!" Celestia leaked a tear out of her eye as she walked into the darkness with her cutie marks.
