For Years now, nopony in Equestria has ever seen Princess Twilight Sparkle sleep. Not even once. She has been known to wander off in her own thoughts. But a nap hasn’t even been observed.

Twilight was in the library of her crystal castle. She held up a few open books with her levitation magic. Reading between each one, cross referencing data from them.

“Princess Twilight!”
“Princess Twilight!”

“Princess Twilight!”
“Princess Twilight!”

A pair of filly twins shouted, trying to get Twilight’s attention.

“Oh! Ah, Yes? What is it?” Twilight replied. Moving the floating books to the left of her.

The twins look at their teacher, a worried expression on their face.

“You alright Princess? You don’t seem like yourself today.” Moon Dust asked with a slight shyness.

Moon Dust approached a bit. Her silver and midnight blue mane bouncing to her movements. Her strength with magic was impressive ever since she was a foal. It’s also why her mane always glows a silvery tone whenever she uses a spell.

“What makes you say that?” Twilight questioned.

“Well, you didn’t even notice us enter the room.” Sun Spark answered.
Her perpetually flowing, pearlescent gold main covered half of her face. Sun Spark’s mental prowess was her greatest talent. She constantly observes things. Relentlessly formulating thoughts based on what she is trying to solve.

“Hm, maybe life as ruler of Equestria is getting to me. Anyway, did you two want something?”

“What will our next magic lesson be?” The twins asked simultaneously.

“Oh! Have you two already completed the lesson?”

“Yes!” They replied. Nearly shouting at their teacher.

“Inside voices you two. Now, show me what you have achieved.”

With a slight hesitation, the twin sisters concentrated their magic on their horns. The mystical veil formed on top. Sparks of magic flew out of the magical veil. And with a flash, both sisters created a spherical shield around them.

“Whoa. Impressive. And it only took two weeks to learn.
Good job, my little pupils. Although, I don’t have anything prepared at the moment for you two.
Hm? What to do? What to do? Ah! Pack your bags girls.. We are going on a field trip.”

“Where to Princess?” The twins asked.

“To the Crystal Empire to introduce you to a friend and relative of mine.
What do you say girls?”

Twilight looks towards her two students. Their eyes sparkled as their faces could only produce an awestruck look.The twins made a mad dash to their home. Only leaving a trail of blurred colors behind them.

“Oh, those two. How will I ever control them? They’re almost as energetic as Pinkie Pie.”

“Twilight!” A voice in the distance yelled.
“Twilight! Twilight!" Spike screamed, entering the room.

"A letter from the Crystal Empire arrived."

"Let me see it." Answered Twilight.

She unrolled the paper and read it.
