DESTRUCTION OF FRIENDSHIP
"Twilight, we need to talk." Pinkie Pie said sternly. "In private."
Twilight Sparkle turned to look at her friend. "What about?" she asked, confused.
Pinkie ignored her. "We'll go to your library. No one's there except for Spike, right?"
"Actually, Spike's not_"
"Great. Let's go." Pinkie started on her way to Twilight's library, not in her usual bouncy way at all. Twilight ran to catch up.
When the two reached their destination, Pinkie Pie shut all the doors and windows and sighed heavily.
"Pinkie, what's so important that you wanted to tell me?" Twilight asked. Pinkie looked up.
"First thing's first." she said simply. "I'm not actually Pinkie Pie."
"Of course you-"
A bright light that filled the room cut Twilight off. She shielded her eyes from the glow that was mysteriously surrounding her friend. It had completely engulfed her, then disappeared in an exploding way.
Twilight opened her eyes to see a light orange alicorn with a fall-colored mane standing in Pinkie's place.
"Are?" Twilight finished her sentence, completely stunned. "Who are you?"
"My name is Autumn Breeze, the Princess of Fall." the alicorn explained with a bow.
"Then where's the real Pinkie Pie?" Twilight persisted. "And how do you know who I am?"
"Actually, that's why I need to talk to you. But the story of how I know you will have to wait until later." Autumn closed her eyes and hung her head. "Pinkie and the rest of your friends...she got to them first." She glanced at Twilight. Twilight kept growing more and more anxious, and also a little confused.
"Who?"
"Thunder Dust, the Princess of Destruction. Twilight, all of Equestria-and everywhere else-is in danger and-"
"Wait, everywhere else?"
"Yes, I'm from Celentoria, a place outside of Equestria. Many years ago, the leaders of Celentoria divided our home from Equestria. All the princesses live in Celentoria...except for Celestia, Luna, and Cadence. And, apparently, you as well. The only way I know about you is because you are a new princess and have the elements of harmony. But that's not the point right now."
"I didn't know that Equestria wasn't the only place..." Twilight thought aloud.
"As I was saying, Thunder wants to destroy all friendship and control in our world. She took your friends because of the elements of harmony. I just hope we're not too late..."
"Too late?" Twilight repeated.
"She's going to use her magic on them first!" Autumn exclaimed. Twilight gasped.
"How do you know all this?" Twilight asked curiously.
"The princesses of Winter, Spring, Summer, and I are the protectors of the elements of harmony. We know when they are in trouble before it happens. This time, everyone's in trouble."
"I have a lot of questions, but I know that we'd better get started on saving my friends." Twilight said. Autumn nodded.
"Here, I've got a map." She used her magic to make a map appear right in front of them. "Unfortunately, Thunder Dust lives in Celentoria. We have a long and hard journey ahead of us..."
Fluttershy, Rarity, Pinkie Pie, and Applejack backed against the wall. A yellow alicorn with a black mane, referred to as Thunder Dust, came closer, an evil smile spreading across her face.
"Hey, mess with them, you mess with me!" Rainbow Dash shouted, flying towards Thunder. Thunder yawned and used her magic to crash Rainbow against the wall.
"Ouch..." Rainbow said, head spinning.
"I really wish Twilight were here." Fluttershy whispered to Rarity. "She'd probably know what to do." Rarity nodded.
"Now, where were we? Oh, yes." Thunder giggled. "Once I'm done with you, you'll all beex best friends! That will be a lot more entertaining!" She created a ball of magic and shot it straight at the 5 ponies.
DESTRUCTION OF FRIENDSHIP
Autumn and Twilight trudged through the Everfree Forest with the Elements of Harmony in a safe, magic-proof box. They stopped when they reached a large, clear, pink wall of magic.
"Is this Celentoria?" Twilight asked.
"Past this force field it is." Autumn answered. "But you won't be able to pass unless you can change into a different pony. Do you know how to do that spell?"
"I could try, but I'm not for sure that it'll work." Twilight replied. "Why?"
"You have to be a resident here to enter. Since you don't know anyone here, I could change into a friend of mine and you could be me."
"Ok. Here 'goes." Twilight concentrated really hard and then she began to glow. Soon, she looked exactly like Autumn Breeze. "Hey! It worked!"
Autumn changed to Posey Leaf, the Princess of Spring. "There. Now we should be able to go." She easily stepped to the other side, as did Twilight. Er, Autumn. Oh, forget it!
Once they were in Celentoria, the two could change back to normal (thankfully).
"Wow!" Twilight gasped. "It's beautiful!"
Autumn nodded and gestured to a large, black structure far in the distance.
"That's Thunder's 'Evil Layer'." Autumn explained. "But it's not very evil. She acts like a baby most of the time, so there are stuffed toys everywhere. More like a nursery to me." She giggled.
"I never thought that it would be so...obvious." Twilight admitted as they started on their way to the 'nursery'.
That's when the box the elements were in started to glow, then fade, then glow, then fade again. Twilight stopped to open the box and check on them. She gasped.
"What happened to the Elements of Harmony?!" she exclaimed. They would usually be glowing, just barely, but now they were losing color and weren't glowing at all anymore. Autumn ran over to look inside.
"Oh no." she breathed. "We're too late."
