It has been twelve years since Twilight Sparkle was shrunk to 1/100 of her original mass to minimize the damage caused by her uncontrollable surges. Twelve years of struggles, challenges and hard work as Princess Celestia’s student, in which the tiny mare found the joy and excitement of facing everyday adventures of a huge world.

One year before Nightmare Moon’s return, Princess Celestia sends her tiny student to learn about pegasus magic from professionals, the Wonderbolts themselves. Much to the princess’s pleasant surprise, Twilight forms strong bonds of friendship during her one month of studies with Soarin' and Spitfire while the Captain of the Wonderbolts, Impressed by Twilight’s talent in magical surgery after the crystal mountain incident, offer her a job as one of the Wonderbolts’ medics.

While Twilight accepts the offer with Celestia’s blessing, provided that it would not last longer than half a year, the other Wonderbolts are not too happy with this idea. Will Twilight manage to win their trust, and what kind of adventures and challenges await her so far away from her home in Canterlot castle? Only time will tell.

This is a sidestory that takes place in "Celestia's Tiny Student" between chapter 20 - "Camping Trip" and chapter 21 - "Birthday Party."

Twilight Sparkle isn't feeling too well, and it is up to Princess Celestia to nurse her back to health. It would be a simple task, if not for the fact that her student was thirteen years old with an uncontrollable amount of magic.

To make matters worse, six years ago Celestia was forced to shrink Twilight to 1/100th of her size so that her untamed magic wouldn't be a threat to Equestria. She would have to remain tiny until she would learn how to control her enormous power.

But surely a two millenia old alicorn with enough magic to destroy a small mountain can handle her littlest, fragile and most magical subject... right... right?

This sidestory takes place between chapters 4 and 5 in Celestia's Tiny Student.

Special thanks for pre-reading to ambion, I took some inspiration from his story called melt, worth checking it out for additional dose of cuteness.

This story is a sequel to Celestia's Tiny Student

(Title changed from "Ponyville's Tiny Librarian" for reason pointed in this blog )

Twilight Sparkle is a one-kilogram pony the size of a large rat, shrunken by Princess Celestia following her entrance exam to the Celestia’s School for Gifted Unicorns to ensure that her power surges would not pose a danger to the ponies around her.

She’s spent thirteen years full of hard training at her new size, facing the life-threatening experiences that came with living in a world of giants. To survive those thirteen years of hardship and joy, of learning and adventure, and of pride and humility, Twilight has challenged herself to be stronger, to overcome any obstacle.

Now that tiny Twilight is on her way to Ponyville to oversee the preparations for the Summer Sun Celebration, how well will this miniature mare fare outside of the confines of the castle? How will the other Element Bearers react to her? How will Nightmare Moon react to the tiny unicorn? Is Twiny prepared to face Ponyville, and, more importantly, is Ponyville prepared to face her?

If I forgot to add someone due to a long time that has passed, please PM me.

During the entrance exam to Celestia's School for Gifted Unicorns, Twilight completely loses control of her magic. Celestia tries in vain to calm her down, but having no other choice she's forced to use a shrinking spell on the filly in order to tone down her dangerous surge of power.

After the exam, Celestia takes the tiny Twilight as her personal student to teach the young unicorn control over her powerful magic, making sure that she will pose no threat to other beings.

Will tiny Twilight be able to step out into a world designed for someone far larger than her? And will her size impede her in the trials of life as princess personal student ?
