Hatred is Magic

Two sisters ruled the land, younger is bad and older is good, younger is banished to the moon by the Elements of Disharmony, and everypony lived happily ever after.

Twilight Sparkle skimmed through the pages of her book. "Hmm... Elements of Disharmony," She spoke to herself. "I know I've heard of those before... but where?" She looked upwards towards the sky.

An idea struck her.

Spike was calmly trotting towards the front door, with a gift for Moondancer on his back. He was expecting nothing but for the door to approach him, absolutely nothing else, definitely nothing, just... nothing.

BAM!

The door smacked his face hard and sent him flying, crushing the gift by the weight of his back. The door revealed his boss, Twilight. "Spike! Spiiiiike!" Twilight look around and above her. "Spike?" She looked down on his cute and lovable assistant. Spike groaned, nursing his nose as she passed him to proceed upstairs.

"You almost gave me a nose farcture!"

Twilight stopped in the middle of the stairs and glared at him. "Hehe, sorry Spike! Um, can you find me that old copy of Predictions and Prophecies." She reached upstairs and quickly took some books from a shelf. She browsed them one at a time.

"No," It was a book about puns and how to pun some puns with puns.

"No," It was a book about parking lots and how to park them with parks.

"NO!" It was a book about perverts and how to spot and pervert them back, ew. Why does she own this book anyway?

Twilight grunted. "Spike!"

"It's over here!" Spike lifted a book using the aura from his horn, he gave it to Twilight. She began to look for page containing the Elements of Disharmony. Spike cleaned the floor of books in a few seconds. He stood next to Twilight to give the book a look.

"Aha! Elements of Disharmony!" exclaimed Twilight, "See: Mare in the Moon?"

"Huh? Mare in the Moon? But that's just an old ponies' tale."

Twilight continued to flip the pages of the book. "Alright, The Mare in the Moon..."

Twilight gasped in shock. "Spike! Do you know what this means?"

"No, not really."

"Take a note please, to the princess."

Passed a few hours...

"My dearest, most faithful student Twilight. You know that I value your diligence and that I trust you completely, but you simply must stop reading those dusty old books! Twilight, there is more to a young pony's life than studying, which is why I'm sending you to overlook the preparations for the Summer Sun Celebration in Ponyville. And, I have a very important task for you: Get a life!"

Spike read out loud the reply from the princess. Twilight could only gave a sigh. They could see Ponyvile minutes away from them.
