The Princess on Discord's Side

"Spike, can you come up here! yelled Twilight Sparkle to Spike, who was probably relaxing carelessly by the fireplace.  "I can't find my quill!  I feel like I have searched everywhere in this place!"

"Coming Twilight!" Spike said as he ran up the steps as fast as his little feet could take him.

"It wasn't that urgent.  It's just a quill you know."  The two began searching for a quill but suddenly... WHOOSH!... cough! ... cough!  Spike coughed up a letter.

"Who is it from?" asked Twilight quickly.

"It is from Princess Celestia.  It says, 'Dear Twilight Sparkle, I have found this book in the castle library.  I thought that it would be useful and a nice little surprise.  I hope it does you well.  Your Mentor, Princess Celestia."

"Finally, something else to read!  I have gone through all of these books already.  I can't wait to get started!" said Twilight excitedly.

"I will be downstairs next to the fireplace if you need me," said Spike.

"The Elements of Disharmony, wait WHAT!" Twilight said, surprised.  "I didn't know that there where Element of Disharmony.  The princess was right, this book is going to come in handy."  She started reading again...

"The Elements of Disharmony are very powerful, although nobody knows all of there capabilities.  The elements include Dishonesty, Selfishness, Despair, Disloyalty, Cruelty, and the most powerful, Bewitchment."

Twilight read this and thought for a minute.  It seemed weird to her that something like this existed.  "Wait a minute, these element are all of the opposites of The Elements Of Harmony."  She started reading again...

"These elements can only be wielded by the draconequus, also known to many ponies as Discord.  Discord has the ability to unleash these elements once every 500 moons.  The Elements of Disharmony can only be defeated by The Elements of Harmony and can strike wherever The Elements of Harmony are not present"

That very moment, Twilight got a letter from Princess Celestia telling her to come to Canterlot as fast as she could and to bring her friends along also.  So Twilight gathered up there friends and they took the train to Canterlot.
