A New Power

   Twilight sprang out of bed happily. Today was the day that Rainbow Dash, Applejack, Fluttershy, Rarity and Pinkie Pie would finally be able to come to Canterlot to have a look at her new house. With all the new Princess-related tasks she had to do, Twilight was seeing her friends less than she wanted to, so today was definitely going to be amazing.

   "Spike, have you seen where I put my quill?" asked the princess. "I need to make sure I have a checklist of what I need to do this week."

   "But can't you just remember what you need to do?" questioned Spike. "I mean, because you're a princess, doesn't that mean you have a super kind of, you know, princess memory?

   "Sorry, Spike, but there are just too many things for me to remember without writing them down, and besides, I might still need that quill just in case Princess Celestia sends a... Wait, what are you-"

   Suddenly, a jet of green smoke flew out of the baby dragon's mouth, and from it formed a scroll.

   "Spike get my quill. I'm sure this is from Princess Celestia."

   "But Twilight..."

   "No 'buts', Spike. Now go and find my quill. Try checking my writing desk."

   "No, really Twilight..."

   "It doesn't have to be the golden quill. Or the one with the gems. A normal quill will-"

   "TWILIGHT!"

   "Yes...Spike?"

   "Don't you think you should at least eat breakfast before reading that letter?"

   After a delicious breakfast, Twilight opened out the letter. It was indeed form Celestia. Twilight read it aloud.

   "Dear Princess Twilight Sparkle, my most faithful student,

Yesterday I was searching through the archives in Canterlot when I found a dusty old book. I opened it up and started reading, and soon I found a spell I think you will be interested in - mind-control.

   I will send the spell to you as soon as I can.

   ~Princess Celestia."

   Twilight quickly re-read the letter, before jumping up in the air joyfully.

   "I've always wanted to learn mind control! This is going to be amazing! And Celestia really thinks I can perform it well!"

   "Err, Twilight..." said Spike, who was just standing and watching as the Princess of Friendship bounced excitedly around the room. "You kinda have a small problem on your hoofs."

   "Wait, what?" enquired Twilight, as she slowed down and then stopped leaping around the room.

   "Well, it goes along these lines... who do you think would actually want to have their mind taken over by... well... anypony?

   Twilight stood completely still, and she thought hard.

   "Ok... maybe you're actually right."
