Prologue - The Equestrian Festival

    Ahem... Today, I will tell you the story of the Rainbow of Harmony.

    Long ago, in the universe where there was nothing but chaos and disharmony, the gray alicorn, known as Spiral Galaxy, was born. She was given the title "the Goddess of Harmony." She has created the three worlds - the human world, the fairy world, and the pony world. Oberon and Titania, Spiral's fairy disciples, have claimed the fairy world and founded Fairyland, the kingdom of magic. The earth, unicorn, and pegasus ponies reunited in the pony world and founded Equestria, ruled by Princesses Celestia and Luna. Three worlds were under attack by the Midnight Mistress of destruction and disharmony, but with help from Titania and Celestia, Spiral created the Rainbow of Harmony and sealed the evil spirit away. Many years has passed. In the big town of Tippington, new heroes rise and the new adventure awaits for the chosen ones...

    One fine afternoon, a blond-haired girl, named Rachel Walker, is waiting for her best friend, Kirsty Tate, to arrive at her house. The two best friends share a wonderful secret, they were friends with fairies. When they were going to Rainspell Island, they have met one of the colorful fairies, known as the Rainbow Fairies, who were banished from Fairyland by the vile ice mage, Jack Frost. The girls helped the fairies defeat Jack Frost and restore Fairyland to its former glory.
    "Hi, Rachel." Kirsty said with a smile, arriving at the front door of Rachel's house.
    "Good afternoon, Kirsty," Rachel said, "Thanks for coming."
    "You're welcome," Kirsty said, then asked "What's new?"
    "The annual Equestrian Festival is coming." Rachel said.
    "What's that?" Kirsty asked.
    "It is a festival where pony enthusiasts come and celebrate," Rachel said, "We get to do arts and crafts, tell stories, and play games."
    "I always wanted to go there." Kirsty said.
    "Me too." Rachel said.
    "Have fun, girls." Mr. Walker said.
    "Be careful out there." Mr. Tate said.
    "We will." The girls said.

    Rachel and Kirsty were walking and they heard music play in the distance.
    "The festival is up ahead." Rachel said.
    The girls arrived at the festival. They could see people dressing up as ponies, like Pinkie Pie, Rainbow Dash, and Applejack. They played pin a tail to a pony, rode on ponies, and listened to stories.
    "Hey, Rachel, wanna do something to impress the fans?" Kirsty asked,
    "Sure." Rachel said.
    Rachel and Kirsty started to imitate Twilight Sparkle and Cadence. "Sunshine, sunshine, ladybugs awake! Clap your hooves and do a little shake!" They said. They then heard a tiny clapping coming from a red rose. They saw a tiny, familiar green fairy. She had dark brown hair tied in loose pigtails, green leaf-shaped earrings, a green long sleeved stretchy top, with leaf shapes around the neck and around the waist, gold bangles, a green leaf necklace, an emerald and gold wand, green stretchy trousers with leaf shapes at the bottom of the legs, and tan colored curly toed shoes. Her wings are pointy and green tinted.
    "Oh, hi, Fern." Rachel said in a silent voice.
    "Hi, girls," Fern said, waving at Rachel and Kirsty. "Are you having fun at the Equestrian Festival?" She asked.
    "Yup." Rachel said.
    "That's good," Fern said, "Penny the Pony Fairy and Helena the Horseriding Fairy are hosting a ceremony at the Fairyland Palace."
    "Awesome." Kirsty said.
    "Wanna come?" Fern asked.
    "Of course." Rachel said.
    Fern used her magic on Rachel and Kirsty. She's turning the girls into fairies.
    Rachel and Kirsty were shrinking to the same size as Fern and yes, they did get their fairy wings. They follow Fern as they left the human world and arrived at Fairyland.

    Rachel, Kirsty, and Fern arrived at the Fairyland Palace courtyard and saw Penny, her pony Glitter, Helena, and the fairy queen Titania.
    "Thank you all for coming to the Pony Festival in Fairyland." Penny said.
    The fairies cheered.
    Rachel felt a breeze, "Do you feel something?" She whispered to Fern.
    "I dunno." Fern replied.
    "Girls! Look back!" A fairy cried.
    The girls saw the dimensional hole open.
    "What's going on?" Ruby asked.
    An evil voice cackled and said "This festival ends here!"
    "Who are you and why are you here?!" Penny cried.
    "I am a source of your doom." The mysterious winged girl said, she had dark purple feathery wings and wore a purple dress and knee-high boots. She created other dimensional holes to capture Penny and Helena.
    "Oh, no!" Rachel cried.
    "Now what are we going to do?" Kirsty asked.

    Meanwhile, in another world...

    A cyan alicorn knight, named Radiant Sword, was helping the purple alicorn princess, Twilight Sparkle. Alicorns are winged unicorns of Equestria. Twilight Sparkle became a princess after finding a magical mystery cure for her friends. Her friends are an athletic rainbow-maned pegasus, Rainbow Dash; a farm mare, Applejack; a party planning mare, Pinkie Pie; an animal caretaking pegasus, Fluttershy; and a fashion unicorn, Rarity.
    "Thanks for helping me with the picnic, Radiant." Twilight said.
    "You're welcome, Twilight." Radiant replied.
    "You were darn impressive, Radiant." Applejack said.
    "This is going to be fun!" Pinkie cried.
    "It sure is, darling." Rarity said.
    "We don't have to worry about eternal night, chaos, changelings, or destruction." Fluttershy said.
    "Meh, how boring," Rainbow Dash said, "I'm in a mood for adventures."
    "A good adventure deserves a good relaxation." Radiant said.
    "Okay, sure." Rainbow Dash said. Suddenly, she saw a dimensional hole open as well as a mysterious winged girl.
    "Long time, no see, Twilight Sparkle." The girl said.
    "How do you even know my name!" Twilight yelled.
    "Oh, I know every name." The girl said. She created dimensional holes to capture Twilight's friends.
    "You fiend!" Radiant yelled, he tried to strike the girl with his sword, but his sword was backfired by the mistress' barrier.
    "Foolish stallion, you will not defeat me, not even your so-called friends can save you." The mistress said. with a snap of her fingers, Twilight and Radiant were sucked into a dimensional hole.

    Looks like trouble for the Mane Six and Radiant Sword. Where did they wind up? Find out on the next episode.
