The Secret Alicorn

Back in Equestria...

It was snowing now and here. In summer. No... it was raining. Snowing. Raining. It constantly changes! thought Twilight. Ugh!

"What...just...happened..here?" Rainbow Dash asked. She scratched her head.

"Rainbow Shimmer has amazing powers!" Pinkie Pie answers. "Princess Rainbow Shimmer! Our friend!"

"She's a monster!" A pony ran up. "She meant to kill us all!"

"No she's not!" Applejack glared.

"It's our fault!" Twilight screamed. "If you have to blame anypony, blame us!"

Everypony stared. And stared.

This is our fault. We pushed her too far. She was scared. Twilight thought. I hate myself. I made one of my best friends run off...wherever she is.

Snapping back to reality, Twilight heard Rainbow Dash bickering.

"Who's that?" Twilight whispered, pointing to toe pony bickering with Rainbow Dash.

"Amethyst Star, mayor of Manehattan." Pinkie answered. Then, she bounced off towards the cupcakes. Twilight saw her stuff her face with them.

"It was her fault!" Amethyst Star argued.

"No it wasn't!" Rainbow Dash shot back.

"She almost KILLED all of us!" Amethyst Star exclaimed. "HA."

"It's called an accident!" Rainbow Dash rolled her eyes.

"Shut up!" Amethyst Star snapped.

"No, you shut up!" Rainbow Dash snapped back.

"Hey!" Twilight stepped in between Amethyst Star and Rainbow Dash. "It was our fault. So..that's why we need to go after her."

"What?!" the rest of the Mane Six gasped.

"Come on, guys. I think she ran towards the arctic north, where the Crystal Empire is." Twilight started to run. The others followed after her.

On the train, everypony was silent. Even after King Sombara was defeated, it was still cold. Rarity handed out scarves.

"These are the only ones I have, so make use of them!" she warned. "And don't lose them!"

"Did any of you know about this?" Applejack asked. "I surely didn't..."

"Not me!! But I'm excited! Our friend's a princess! Are you excited? I'm so excited! I hope she comes back! I mean life wouldn't be the same without her!" Pinkie rapidly chirped. "And-"

"Pinkie, shut up." Twilight snapped. "I don't think any of us knew she was the newest princess.... Certainly not me."

"Heavens, no!" Rarity flipped her mane.

"Let's just... keep walking," Twilight sighed. "Ugh..."

After a little walking, they entered the Crystal Empire. Sparkly as always, the Crystal Ponies were standing around gossiping.

"THERE SHE IS!" one shouted. "TWILIGHT AND HER FRIENDS! THEY MUST KNOW WHERE RAINBOW SHIMMER WENT!"

"It looked like she ran past here, the Crystal Empire," Rarity answered. "Has anypony seen which direction she went?"

"I think that way." A tan pony with blue mane stepped up, shimmering. "Towards the Snowy Plains. I saw a flash running that way, and it looked like an alicorn."

"Thank you." Twilight nodded. "Girls, maybe we should go to the Crystal Castle and get rested up for tomorrow..."

Back in Rainbow Shimmer's castle, she stepped out on the balcony. She saw the faint glimmer of the Crystal Empire's Crystal Heart protection bubble. She then moved her top right hoof to make a snow pony. She remembered her memory... her sad memory.

Once, playing with her younger sister Glacier, who was a normal alicorn, they were in a large room in the castle with portraits of the past rulers. Her sister was playing on the ice. Glacier's pure white coat and silver mane matched the winter theme perfectly. But then, Glacier was running through the snowbanks. She was on the slide, but accidentally jumped off it and didn't slide.

"Glacier!" Rainbow Shimmer had cried out, sending magic. But the ice landed in Glacier's heart. Rainbow Shimmer was alone at the castle. It was said true friendship would undo a frozen heart. She tried, but Glacier had frozen and Rainbow Shimmer was ordered to hide her powers.

"Glacier, what would you do?" Rainbow Shimmer wondered. Then, she walked inside and discovered her crown in the ice. She snatched it out.

"I hate this stupid crown!" Rainbow Shimmer sang, levitating it. "Poof, it disappeared!" She then vaporized the crown...

Rainbow Shimmer made a snow pony, remembering Glacier. Somehow... It came alive! It ran down the stairs, high spirited. Just like Glacier.

"Glacier... There's a snow pony for you. It'll never make up for your death, because I was stupid. And I'm sorry Glacier, I miss you." Rainbow Shimmer sighed. "I love you and will never stop missing you."

Rainbow Shimmer walked into a room with one door. She started to cry. Her tears became ice, which added to the castle.  She wasn't afraid- just sad, so she could still control her powers.  She wished she had never been born with these stupid powers. It wasn't fair. How come SHE had to be the one controlling the weather?! Born of a PRINCESS?!

Life seriously stank sometimes.

Back with Twilight and her friends, they were saying thank you to Princess Cadance and Shining Armor for the hospitality for one night.

"Thank you for breakfast," Twilight smiled. "But we really must be off now."

"Maybe I should go with you?" Shining Armor suggested.

"No thank you," Twilight answered. "But it's nice of you to offer."

"Okay," Shining Armor replied. "Good luck finding and bringing back your friend!"

"We have a few things for you, though." Princess Cadance started to walk. "Follow me."

Once outside, they found a crystal sled. It had winter coats, blankets and scarves in it. A crystal gem was powering it, and there were several others in a bag.

"Why... IT'S GORGEOUS!!!" Rarity screamed. "I LOVE IT!!!"

"Oh, and Twily?" Shining Armor used Twilight's nickname.

"Yeah?" Twilight asked.

"Be careful." Shining Armor placed his hoof on her. "I don't wand a dead little sister."

"What makes you think that?" Twilight raised an eyebrow. "I won't be dead."

"Well..." Shining Armor starts, "Let's just say that sometimes, when alicorns are mad or upset, things aren't pretty. Especially weather princesses like Rainbow Shimmer. Ice or thunder to the heart is no laughing matter. It could freeze or electrify a pony and maybe cause them to die. Even on accident."

"She's our friend!" Rainbow Dash interrupts. "A friend would never hurt us!"

The others were already in the sled, so Rainbow Dash and Twilight hopped in.

"Good luck!" Shining Armor and Princess Cadance was waving goodbye. "Take care!"

And so off they rode to find Rainbow Shimmer.
