Cataclysm of the Lunar Empress

"Do it! Don't be weak, do it!"

Nightmare Moon's hollow-sounding voice rang through Luna's ears. As she levitated the blade closer to her, a single tear slid down her blue face, twinkling in the moonlight. Shaking furiously, she levitated the knife to her collarbone.

"Yes, now!"

Slowly, Luna began to cut a message upon her perfect skin. The single tear had now become a flowing river down her face. Her eye was wide and fearful. The other one's pupil began rapidly changing, a symbol of Nightmare Moon taking over her body.

"Deeper!" Nightmare screamed, in a voice only the Princess could hear. Biting her lower lip so hard she nearly drew blood, she made the knife cut up and down over her neck, writing, 'I am your Nightmare'.

"P-Please, make me s-stop," she wept, staring in horror as multiple streams of hot, sticky red liquid ran down her glistening neck, the sound of cruel laughter echoing into her very soul.

"Pathetic! You're weak, admit it!"

"N-no," Luna whimpered, dropping the knife with a clang onto the polished floor. To her right, her shadow loomed menacingly on the shining, curved wall. It was tall, armor-covered and the darkest black to be known. Currently, Nightmare Moon could only possess Luna's shadow and eye, as well as a tiny bit of her mind. But she was growing stronger each day, taking more and more control over the young Princess.

The pair were stranded on the moon, in a large dome palace made of moonstone. There were no windows except for the foal-sized one at the tallest point of the dome, allowing the moonlight to shine down in a large circle. The palace had no rooms, so Luna slept in a dark corner against the marble-like wall. She was often cold, and hungry. The only meal she had was moonwater, the only edible substance found on the moon. As a result, she had thinned immensely, so much that you could point out every one of her ribs.

"Ugh, you're pathetic. Can't you see i'm trying to help you grow stronger? To grant you the ability to KILL your sister for the horrible things she's done to you?"

Luna drooped her head and collapsed onto the floor. "Y-you're wrong, my s-sister did what was r-right!" she whispered, staring at the massive wall of the moonstone dome.

"Then why don't you escape out the window? You can fly,"Nightmare mocked. Luna's wings had been bound to her back in a strange, black, almost gas-form substance, put there by Nightmare Moon's dark magic. It was unbreakable, and every time she tried to remove it squeezed her harder. The first day she was put on the moon it tightened so much that a bone at the end of her wing ripped her skin away.

"Leave m-me alone, you f-foul creature," she said, as she squeezed her eyes shut, not wanting to open them in case Nightmare managed a solid form and appeared before her. Her twin laughed, the sound echoing off the walls. Both eyes now releasing massive amounts of water, she attempted to rest, her tears dripping with a thunk onto the floor, creating a small puddle that leaked onto her scarred hooves.

"Oh sister, how I miss you so," she whispered.

Princess Celestia frowned as she gazed at the glowing white sphere in the sky. Being a Princess, she already had many difficult duties to attend to, whilst now she had to not only raise the golden sun every morning, but the nighttime orb named the moon as well. It had been heartbreaking, banishing her younger sister to the moon, eons away. Her mother and father had too noticed that Luna's behavior was changing, and advised her to send her away before she changed into something terrible.

In her disbelief and misery of her sister's absence, Celestia had begun writing letters to her sister, only to burn them in the fire, as she knew Luna could not receive them. She often locked herself in her room, sobbing over a picture of the sisters as foals, cuddling. Oh, how badly Celestia wanted to see her sister! It had been already 100 years, and she did not think she could last 1,000.

Celestia often wondered if her sister's appearance had matured at all. Celestia's had, and very much so. Now, instead of having a still, light pink mane and tail, it had changed  to have the light colors of the rainbow and flowed on its own. She had also grown much taller, taking the role of the tallest Princess.

"Oh sister, how I miss you so," she sighed, gazing at the moon longingly. With a pang, she remembered all the times they would play or read together. They'd laugh together, eat together, cuddle, and other sisterly things. Celestia realized that she and her sister had the closest relationship out of anypony she'd ever seen.

Suddenly, Celestia had an idea. Using her horn, she swung open the window and hurled herself towards it. She fell, until at the very last moment she swooped upwards, gave her wings a mighty flap and soared into the sky. She raced to the moon, faster than she had ever flown before. Tears stained the sky as she flew at top speed. The possibility of Celestia preforming a Sonic Rainboom was steadily increasing. But just as she was about to enter space, she closed her eyes.

And fell.

The speed of her descent caused the wind below her to make a loud whistling noise. Smiling ever so slightly, tears still gushing from her purple eyes, she raced towards the ground. With a sickening crack, she collided with the hard surface of the stone path. Her body was a crumpled mess, blood forming a massive puddle around her glistening white skin.

"Oh my- HELP! SOMEPONY HELP!" a pony screamed, eyes wide in horror at the sight of the Princess. A small group of nearby guards ran towards the screaming mare. Two of them tried to calm her down, but all she would do was scream and point a shaking hoof at the limp alicorn. The rest of the guards rushed towards Celestia, their own eyes widening. Half of her face was crushed inwards, revealing bone, flesh and blood. One eyelid had been torn off. Her wings were hanging at odd angles, exposing multiple bones. Her hooves were all crushed and cut from her shoes, which had shattered at the force of the fall. Her mane and tail were both disheveled and coated with spots of red.

"Dear God- is she alive!?" a guard asked. Another one slowly and cautiously made his way to Celestia's unmoving body. With one hoof, he gently prodded her chest. The Princess opened her eyes, and with a raspy voice, thanks to a crushed windpipe, she whispered,

"Luna..."

With a ghost of a smile still etched upon her face, her eyes went dim.

The Princess was dead.
