Equestria's trouble.
Prologue:
In a orange afternoon, with a bright sun slowly going down to let pass the Moon, a little filly with a notable red mane named AppleBloom, was walking into the path to get home.
―Hey AppleBloom! AppleBloom!― Someone said behind the light yellow crined filly, it was Scootaloo, reaching her with her scooter. ―Oh, hi Scootaloo!― AppleBloom greeted her with a drawn smile in her face, she was going to start a convesation theme, but the purple haired filly interrupted her. ―Hey, i need to tell you something, i think you can understad what happened yesterday.― With confusion about what Scootaloo said, AppleBloom replied: ―What happened?― She asked. ―Well, RainbowDash has been acting strange last afternoon... She said very weird things... that all the world is going to end, that even Celestia couldn't stop the destructon... i don't know, but i'm worried and-
She couldn't end her reply, a noise interrupted her, the noise was from a pair of ponies, two sisters, Sweetie Belle and Rarity, with a package in their backs. ―Hey, do you know what is happening?― AppleBloom asked to Sweetie Belle, she replied: ―The Mayor told us to go to Canterlot!― She said rapidly, ―Why?― The orange eyed filly asked again. ―I don't know exactly why, but i think its a plague.― That words that Sweetie Belle said made Rarity scared. ―PLAGUE?, THATS EVEN WORSE!― She Screamed, the green eyed filly, worried, tried to calm her sister, they went to the train station, and went out from Ponyville to go to canterlot.
―Well, is just the two of us, i think.― Scootaloo said looking to her friend, and, they went to Sweet Apple Acres, because AppleJack was there. In their way to the barn, they encountered AppleBlooms big sister, and the Princess Twilight Sparkle. ―But Rarity can't go with us!, she still thinks is a plague that will ruin her dresses! ― Someone said in the barn, it was AppleJack talking to the Ponyville Princess.
―And Rainbow Dash?
―SHE'S CRAZY!
―Oh. And Pinkie Pie?
―The Family Cake.
―And FlutterShy?
―Too Scared.
―And Starlight?
―She's in the village, packing too.
―Oh, well...
Then, the two fillies entered into the barn, and asked:
―CAN WE GO?!―
―No, y'all too small.
―But AJ...
―I said-
In that moment, Twilight interruped Applejack, ―No worries, i think we can bring them into our mission.― AppleJack's eyes opened like big plates of Twilights words. ―WHATS WRONG WITH YOU?! YOU'RE A PRINCESS!― Twilight laughed and said: ―Listen, i know they're to small for this mission, but i bet that they can solve it, even tho, i solved difficult problems when i was their age.― Applejack thinked a little, and said her final decision: ―Fine, but stay with us.― The blond pony said.
―Wait, where's Big Mac?
―He bringed Granny Smith to Canterlot.
― Oh.
―Be prepared, because this mission will decide Equestria's destiny.― Twilight said, and the Two mares, accompained with two fillies, their adventure started.
