"Twilight!? Twilight!" shouted spike.

"Twilight! We've got a letter from Princess Celestia."

"So?" said Twilight, still sleepy in bed, "I'll read it later. Just put it with the other ones below the bed."

"But, it's red. It means it's urgent. The envelope is red. The ink is red. Even the paper is red. I..I don't even know how can I even read this one."

A moment later, some sort of a faint voice shouted

"Twilight? Are you awake?"

"Huh?" said spike.

"Twilight? I got something for you."

"Who's there...oh." said Spike from the window, "Sorry Rarity, but you might wanna come back. Twilight's eyelids are sure heavy yet."

"Oh, sorry then, guess I'll just go to Princess Celestia alone."

"Wait, WHAT!?" shouted Twilight as she flew from the window, "Princess Celestia summoned you too?"

"Well, yeah" said Rarity. "In a matter of fact, everyone got a letter from the princess: Fluttershy, Applejack, Rainbow Dash, and Pinkie. Even Discord got one."

"PRINCESS CELESTIA CALLED DISCORD!?" shouted Twilight.

"Well, yes" popped Discord, out of nowhere "and it might be some job we're doing together. Oh, what fun it is!"

"Together?" said Twilight, "This is ridiculous. Working with Discord..."

"Now, now" said Discord, while sitting on a tree (his thinking tree, perhaps), "We can't just stand here, hating my state of being invited. We need to go now. We can't let the princess wait forever."

"And I can't wait for this whatever-job-this-is be finished."

"Certainly, Twilight. I can't even imagine why the princess called us. Why, it's not even sunrise yet. It must be some urgent mission that our envelopes, ink, and even the paper is red."

"Your paper is red?" said Discord "Hmmm, strange."

"What's strange" said Twilight.

"Well, you got yours red, and I got mine, well blue."

"And what's supposed that to mean?" said Rarity

"Who knows. Your letter came from Celestia. Maybe, It's from Luna. Besides, it is her skin's color."

"We waste no time, let's go!" said Twilight.

They rode off to the hills, through the Everfree Forest and flew up (Twilight was on solo, while Rarity rode on Discord) 'till they reached Canterlot.

"I was expecting all of You" said Celestia

"And I'm expecting Discord." said Luna

"WHAT!? DISCORD GOT INVITED TOO?" shouted the rest.

"Now, now." said Celestia in a calm, soothing voice, "I summoned Discord for a very special purpose. You all follow me."

"And You, follow me." said Luna, pointing to Discord.

Each of the team went to separate halls. Celestia brought the ponies to a hall that led to an underground dungeon, while Luna brought Discord to a secret room. Each was given a special task. And what a surprising task it is. If I were you, I would suddenly regret this decision that I accepted that challenge
