Twilight stood in fron of Luna's door, once again going over in her head what to do. She knocked and waited.
"Come in," Came a bored voice. Twi pushed open the door --unlocked-- and stepped inside to darkness. The small beam of light from the door shone onto the floor, revealing a patch of dirty carpet and a half eaten bag of potato chips, contents spilling out into an unwashed soda stain. Twilight stared at this only visible part of the room, puzzled.
"Luna?" She asked, searching the darkness. "What is all this?"
"Shut the door," Luna's voice grumbled, followed by a smacking and crunching sound.
"What in the name of..." Twilight couldn't complete her sentence as the room slowly illuminated. Luna was using her powerful magic to do many things; Read a book, slice a pizza, open a bag of potato chips, play video games, and keep the room lit. She looked like an indifferent factory of laziness, things of menial work floating about her head.
"I believe you were about to swear to Celestia," Luna mumbled, not looking up from the television screen she was playing on.
"Huh?" Twilight closed her gaping mouth, averting her stare to gaze around the rest of the room. It all looked quite similar to the patch she had first seen, trash strewn about and soda stains dotting the once-white carpet. Then Twi jumped slightly when she noticed Luna's crown amongst the piles of trash. As she looked, she realized all the princess's royal garments were tossed about in the garbage; Crown, boots, crest, and all.
"Luna, you are a princess!" She exclaimed, shocked.
"Only because I was born one. It's not like anypony actually needs me, they were fine when I was on the moon."
"No Princess Luna, I will not have you speaking this way." Twilight picked up the trash piles on the floor, levitating them outside. She popped all the soda stains out of the carpet, leaving the floor shiny and white. She intercepted Luna's magic with her own, putting away the food and games. She placed Luna's royal garments by her hooves. While she did all this, Twilight Sparkle sang.
"You've come such a long, long, way.
"And she's watched you, from that very first day.
"To see where you might go, to hear what you might say, to test what you will do with the power that has been inside of you.
"I know what it feels like to be low.
"And I get, she doesn't know just what you know.
"But you are a princess.
"And you wear a crown, yes.
"You know that we need you,
"So please lead us dearest princess of the moon.
"You may feel,
"Like nopony ever sees what you do.
"But you'll see,
"That we love to celebrate under your moon.
"You're not just her shadow.
"You thrive with your own will.
"You will make yourself free.
"Yes it's time for you...
"To control your destiny!"
Twilight held the last note, lifting up Luna's crown and placing it on her head. Luna smiled and picked up the other garments, putting them on. She hopped off her bed and faced Twilight, looking as much as a princess as her sister.
"Celestia wrote that song," She said suddenly, smile disappearing.
***
Luna sat alone in her quarters, thinking. After she had made her snide comment at the end of Twilight's song, the latter had nodded. Then Twi said she had changed the song, now making it her own. She told Luna she should do the same, taking things into her hooves and creating her own life. The princess of the night smiled at the former unicorn's wisdom, walking over to her window and looking out at Celestia's room.. As she watched, Luna saw Celestia come to the window, staring out over Canterlot. When Celest glanced in her direction, Luna ducked, not yet ready to confront her sister. But as she thought, crouched underneath the windowsill, Luna couldn't stop thinking about how sad Celestia looked. She contemplated for a long time, then finally decided to talk with her. When Luna looked back out the window, she found Celest's window was closed and the shutters drawn. This discouraged her a bit, but she set out anyway. As she got closer to Celestia's room, disturbing sounds entered her ears. Loud crashes sounded from inside, followed by hard thumps and hoofsteps pounding on tiles. Unnerved, Luna headed quietly to her sister's room.
"Sister?" She whispered as loudly as she dared. "Are.... Are you okay?" She paused by the door, listening. There were several tense seconds of silence. So many that Luna began to wonder if she had imagined the whole thing. She lifted a hoof to knock, then paused.
What do I say to her? Luna wondered, willpower fading. Suddenly, she could hesitate no longer. Celestia's piercing scream ripped through the air, then was cut short. Luna stumbled backwards, shocked.
"Sister!" She yelled.
"Luna!" Celestia's anguished cry once again stopped abruptly, followed by an unfamiliar high-pitched voice.
"Where is she? What did you do to her? What happened to Nighty?"
Luna burst into the room, splinters of the broken door flying everywhere. She skidded to a halt where Princess Celestia lay sobbing at the hooves of two princess-sized mares, a unicorn and a pegasus. The pegasus was a hot pink, with a white mane that dangled in thick strands around her face. Her tail did the same, spilling out all over the floor. The unicorn was slightly taller, with sparkly silver fur and a dark red mane and tail, both cut short and greased in clean, precise, bunches. The pegasus's eyes were a fiery green, while the unicorn's a pale yellow.
Luna stumbled where she stood, staring with aghast disbelief at the ponies before her.
"Plaz! Solar!"
