Hi! This is my first MLP:FiM fanfic, so I hope you enjoy.

As the lightning flashed, and the thunder crashed, the six ponies huddled together in Sugarcube Corner. Spike was clinging Rarity, his nails digging into her. But she didn't say anything yet as the Mane Six calmed themselves.

"I didn't hear anything about a storm happening tonight," Rainbow Dash announced, looking around. The other shivered in the cold as thunder struck again. The few other ponies invited to Pinkie Pie's party were silent. They moved away from the little windows in Sugarcube Corner.

"Is there anything you can do?" Twilight Sparkle asked, her lavender eyes sparkling at the rainbow-haired Pegasus. She shrugged, not knowing what to say.

"I don't think it would be a good idea for any pony to fly in this weather," Rainbow Dash commented, adding, "But then again, I'm not any pony!"

She was almost out the door, but Applejack bit the kaleidoscope colored tail and pulled Rainbow Dash back down to earth.

"I don't think so, sugar cube. Lets just wait it out," she smiled. Rainbow Dash sighed an annoyed sigh, but as the thunder crashed again, she was silently happy that Applejack had stopped her from facing that horrible storm.

Fluttershy was shivering in the corner, Pinkie Pie was trying to get the party started again, Applejack and Rainbow Dash were both having a heated argument over the storm, and which one could last longer n the weather, Rarity was worrying about her shop and Twilight Sparkle wondered if the storm would ever pass. It had seemed like it had been raging on for hours, even though it had only been a few minutes. But unbeknownst to the ponies in Sugarcube Corner, the storm was raging on through all of Equestria.

Princess Celestia was running through all her thoughts, hidden in her tower room in Canterlot. She had the door locked and two royal guards at her door to keep any pony out.

Yet the door still slowly opened, and a little pony seemed trot quietly in. Celestia was seated on her bed, which was round and elevated above the floor a good four feet. She had two little staircases leading up to the elevated platform.

She was sitting in the middle of her bed, staring out the window, watching as the rain hit it and slid down the glass. The thin, gold, ornate frames that held the glass once intrigued her, but suddenly seemed to block her view. She just stared out over the field below her, how the trees were swaying to the wind, the moon illuminating the little puddles, the majestic, violet sky filled with stars.

"I thought the door was locked," she said, not ripping her gaze from the night. She thought nothing would make her move from her position.

"But… Sister, I have news," a quiet, soft voice spoke. Celestia delicately gasped, and turned her head to see the little blue unicorn/Pegasus stare at her with wide eyes.

"Luna… you're here!" she happily said, launching off her bed and landing perfectly on the ground. Her long, blue, pink, and green hair was waving in the air, and her eyes were full of wonder and happiness. Her sister hardly left her room, and yet, she ventured out to see Celestia herself!

"What are your news, Sister?" her voice was happy but soft, and she wrapped her neck around her sister, hugging her briefly. She walked her sister up to her bed, and they sat together just staring at the raging storm. It was almost peaceful, in a dark way.

"There's a reason for the storm," Luna was mesmerized as her sister was at the storm. The just leaned on each other, thinking about how much they missed each other, Luna regretting the fact that she turned dark only a few days ago. She just didn't know how to tell her sister the news, if she would believe her or not. She thought it was worth a try.

Back in Ponyville, the ponies shuddered at the cold and the wind. They had moved to the center where the few ponies spoke softly to each other, playing simple games and nibbling on what was left of the food.

"I know what will liven up this party!" Pinkie Pie announced, jumping to her feet. The other ponies watched her as she pushed two tables together, and jumped on them. Pinkie Pie began to sing.

"I know, it looks glum, but trust in me, and we can have some fun! We can have some–"

"Pinkie Pie!" every pony yelled, cutting off her song. She looked at them and smiled, stepping down from the table.

"Glum and fun don't even rhyme…" some pony mumbled and a few others laughed. The party was dying fast and none of the ponies wanted to talk or play games. They eventually just all fell asleep in a pile of pones for lack of pillows and blankets.

Luna feared her sister's response, but was determined to tell her thoughts. To her, she was taking a huge step onto a wobbly, rotting, wooden bridge. She could get across by walking, but she could always fall through one of the holes. The easiest way would to be to fly across, and avoid the bridge all together, but she needed to cross the bridge. She needed to face her fears and speak up for a change.

"Sister, I believe Cosmo is coming," Luna smiled awkwardly and nervously, trying to have her sister believe her. Celestia stared at her blankly before the gears in her head clicked and she gasped at her sister.

"You believe that's why the weather is happening? A rogue storm is nothing out of the ordinary; storms roll out of the Everfree Forest all the time!" Celestia laughed and her sister, a bit hurt from being shot down, swallowed her fear, and began to explain herself.

"It is predicted in the Royal Library. I've been reading about how a horrible storm will mark when Cosmo returns. I know you don't want to believe, but Cosmo will return, I just don't know when. We cannot inform any of the ponies, though, and cause uproar throughout Equestria. Please, Sister. I've never been so sure of something in my life," she pleaded. Her voice was louder, but it could still not be heard outside the door.

"You really believe this? I-I'll look into it," she stuttered, thinking about what her younger sister had just told her. She hadn't heard her speak like that in a long time, and she desperately wanted to believe her, but she couldn't wrap her head around the idea. Cosmo? Returning? No, she left long ago… there's no way she would just come back to Equestria. Celestia began to wonder…

Well, that was the first chapter!
