Prologue
Once upon a time there were two alicorn sisters. The eldest sister was Celestia and the younger sister was Luna. Together they ruled over a beautiful land called Equestria, protecting their pony, pegasus and unicorn subjects. But one day, Luna turned against her sister. No pony was enjoying her beautiful night, but every-pony liked her sister's sunny day. Jealousy turned to hate. They fought, and Luna was banished to the moon.
At least, that's what every pony was told. No pony knew Celestia's dark side.
It was a lovely, sunny day in Ponyville. Twilight Sparkle stood outside the Ponyville library, which was also her house. She was admiring the beauty of the day when she heard a familiar voice up in the sky.
"Hey, Twilight!" a cyan pegasus yelled as she waved, nothing more than a blur in the sky.
"Hey Rainbow! What's up?" Twilight asked. The purple unicorn smiled.
Rainbow Dash zoomed down, landing next to Twilight. "Nothing much, just practicing for the Wonderbolts! They're coming to town at the 1001 Summer Solstice Festival. Gotta show 'em what I'm made of, you know?" Rainbow Dash winked.
Twilight rolled her eyes, "Anyway, I needed to talk to you, but since you're busy it can wait." She began to walk towards the library door.
"Wait!" Rainbow flew over to her, putting a hoof on her shoulder. Twilight looked back. "I'm so awesome, missing a practice won't affect me. I could do it in my sleep!" Only her eyes betrayed her nervousness.
"I'm glad you're available! Are you sure?" the purple unicorn asked.
"When am I NOT sure?" Rainbow asked.
"Good point. Can you go get the others for me and meet me in my study room?" Twilight asked.
"Sure!" Rainbow Dash said, then disappeared loudly with a blur.
"I need some earplugs," Twilight muttered.
