Frozen Darkness [December 16th, 2014]

A.N: Since no one's gonna write any kind of decent song for Celestia for Frozen parodies, I felt doing a fanfic about Celestia and Luna's relationship or whatever. Frozen isn't the best movie ever, but it/is/really good. Uh... I guess, as always, hope you like.

Luna stared down at the world below on the balcony of the palace. The houses looked so far away and the ponies wandering around Canterlot looked like ants. As she looked up, she noticed the sun was beginning to set. It was almost like her cue nowadays. It was time for her beautiful night to begin.

With a short sigh, she flew up, away from the balcony. She cast her magic, making the moon begin to rise in the sky. The sun had completely disappeared beyond the horizon, allowing the full beauty and radiance of the moon to glow.

As she touched down on the balcony, a familiar voice spoke behind her. "It's beautiful."

Luna turned and smiled. "I'm glad you think so, sister."

"Shall we go?" Celestia suggested. "We've got a big day tomorrow."

"We do?" Luna asked, suddenly forgetting.

"Of course," Celestia chuckled. "Tomorrow is the Summer Sun Celebration."

"Oh... That," Luna sighed disappointedly, stepping away from the balcony and past her sister.

"I thought you'd be more excited," Celestia tried, still smiling. "You'll get to come with me."

"And show my face to the whole kingdom?" Luna asked, feeling threatened. "I couldn't."

"Luna, you're not a monster," Celestia said calmly. "Just because you have the dark matter inside you, it doesn't make you evil."

"It could one day, sister!" Luna said fearfully. "And I don't want anypony to be around when it happens... Especially you." Her head dropped dejectedly.

"Luna, you'll be fine," Celestia assured, draping her wing over her little sister, hugging her close. "I promise."

"Ok," Luna sighed, hugging her sister back.

Hours later, the citizens of Canterlot gathered around the ceremonial court, waiting for the moon to set and for Celestia to raise the sun.

The eldest princess of Equestria stepped forth, smiling brightly as her subjects welcomed her with thunderous applause.

"Fillies and gentlecolts," she greeted. "It is my great honor and privilege to stand before you to celebrate this, the longest day of the year."

More applause sounded as she said this, and Celestia looked over her shoulder, motioning. "Come on, Luna," she encouraged.

Luna's eyes travelled down, examining the ground. "I... I don't know."

"I just want you to be happy. I'm sure everypony will love you just as I."

Slowly, she stepped up with her big sister, and the applause gradually faded.

"Luna, if you please, lower the moon to make way for the dawn," she said officially, adding a playful wink that only Luna saw.

With a small smile, Luna graced her wings, and began to hover above her sister. Before she started to lower the moon however, her eyes flashed. Frightened, she looked down at Celestia. "Sister," she whispered as she descended quickly.

"What's wrong?" Celestia asked in concern.

Luna didn't get to answer her. Instead, the dark matter inside her had taken over her thoughts. "I refuse to make way for the dawn!" she shouted, nearly missing Celestia as she shot dark magic at her.

"Luna! What are you doing?" Celestia gasped.

"Silence!" Luna commanded. "I am no longer under your control! From this moment forward, I declare that the night will last forever!"

The princess of the night suddenly flew high above the crowd, so everyone could witness her transformation. Her coat turned black as night. Her eyes became sharp and glowed with a lust for power. Her hair morphed into a deep blue color and swirled around her head gracefully. Finally, an elegant set of armor was added, shining silver in the moonlight. She was no longer Celestia's beloved sister.

"Bow before your new princess; Nightmare Moon!" she cackled.

"No..." Celestia muttered. "It can't be... I promised it wouldn't happen."

"And look what happened," the evil mare chuckled. "You didn't keep your promise, did you."

Celestia bowed solemnly. "I'm so sorry, Luna."

"Don't be," Nightmare Moon huffed. "Thanks to you, the night will be eternal!"

"No!" Celestia cried, taking off into the night.

"Where do you think you're going?" Nightmare Moon called after her. As the two flew through the night, the mare of darkness shot at her sister, trying to knock her down from the sky. Celestia dared not fire back. She didn't want to hurt Luna.

But before she knew it, she was plummeting to the ground, her right wing singed with dark magic. Her scream was quickly silenced as she hit the ground unconscious.

As Nightmare Moon looked on, she felt no sympathy and smirked. If her true self was showing, the part the dark matter had locked away, she would be crying. As she flew away, Celestia slowly gathered what little strength she had left and stood up. "Oh, Luna..." she whispered. She looked to the pedestal on which the Elements of Harmony rested. "Please forgive me. I have no other choice." She could feel tears in her eyes as she gathered the elements and started her search for Nightmare Moon.

A.N: The actual beginning of this fanfic was probably like the day before the party in Frozen. The end here is at the part where Anna goes looking for Elsa in the snowstorm and such. Oh well, I guess I won't be putting an equivalent to Hans, Kristoff, Sven, and Olaf in there but SCREW IT. IDC.
