Cataclysm of the Lunar Empress

It had now been 200 years since the banishment of Princess Luna. Luna had no way of knowing this, as the sky had only the appearance of night.

The Princess' parents had come to Equestria from their castle in the sky, to discuss who was to take care of Canterlot. In the end, her mother, Queen Galixia, was to rule while her father, King Cosmos, went back to their castle to figure out what would happen to Equestria. Luna was forgotten completely in the storm of mourning ponies. Everypony in the Crystal Kingdom lost their marvelous crystal coats, including Prince and Princess Cadence and Shining Armor.

The pegasi stop creating rainbows, and the weather was cloudy each day. They pulled all of their feathers out of their wings, making the ability to fly nearly impossible. The unicorns all chopped off the tip of their horns and placed them into a large river, named after Celestia. The earth ponies fasted, their ribs visible to all. And still, nopony thought of the banished Princess.

Except the Queen.

Cosmos, what about our baby Luna?

What about her, Galaxia?

She's still on the moon. Don't you think she should know, Cosmos? It IS her sister!

No. If she started to be a monster then she surely is one now.

How could you say that!?

We must not release her until it has been 1000 years and she has changed, Galaxia!

"Wake up, maggot! We've got work to do."

Luna awoke with a start as a cold, solid glass shoe collided with her head. She looked up. There was Nightmare Moon, solid and terrifying as ever. Luna stood up on shaking legs, swaying side to side from lightheadedness.

"Y-you!"

"Yes, yes, I am solid. I feasted on your dreams and gave myself this form. Fancy, isn't it?" Nightmare said, clicking her tongue. Using her horn she levitated Luna up into the air and threw her across the dome, crashing into the wall. "So weak and lame!" Nightmare Moon exclaimed, cackling evilly. "Get up and fight me!" She assumed a battle stance, smirking, eyes narrowed.

Luna struggled to her hooves. As she attempted to use her magic, all that happened was a few sparks flying out of it.

"Oh, I suppose this will be fair if I-" not needing to finish, Nightmare Moon removed the cord that strapped Luna's wings to her back. She stretched them and gave them a few flaps. They were very weak and beat up from the rope.

"Let's do this," Nightmare Moon chuckled. Also assuming a battle stance, though less fearsome, Luna frowned and glared. Nightmare shot a blast of blue light at Luna. She ducked just in time, the attack creating a small crater in the floor. Using her magic to pick up the pieces of moonstone that had been attacked she threw them at Nightmare Moon, one hitting her squarely in the face. There was a loud cracking sound as the moonstone chunk split in two. Nightmare's Armor had barely been scratched.

"It's going to take more than that to kill me!" she roared, rushing towards Luna as the Princess did the same. Their magic collided, causing the magic of the ponies to fill the dome with a bright light. As Nightmare Moon took a step forward to increase the force of her magic, Luna did the same. Soon, the pair were barely a hoof away from each other. They glared and gritted their teeth. Then, knocking Luna over in surprise, Nightmare Moon had swung her horn upward, causing the beams to shoot a large hole into the dome.

"I'm free!" she yelled, cackling madly. Luna watched in horror as Nightmare Moon flapped her wings once and soared upwards through the hole. Her cruel laughter echoed in Luna's head long after she had left.

Luna began to weep. She had failed her sister, herself, Equestria, her parents. In fury, she began slamming her head against the wall so hard that a small crack began gradually climbing up it.

After a particularly furious slam, she heard a cracking sound.

The tip of her horn fell onto the ground near her hooves.

Luna didn't make a sound as the dome fell atop her.
