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."

Also, apparently, an animated trailer.

In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

Orphaned from birth, with only the memories of a soft touch and gentle voice to remember her by, Twilight yearns for her mother. What pony wouldn't want to know why they were abandoned, why they were left to be found by the Princess of the Sun herself.

That was nearly two decades ago though. Twilight was older now, and hopefully wiser. She is happy with her two best friends, Cadance and Shining Armor. They are like family to her, the brother and sister she never could have. Though dreams still haunt the young mare, dreams of lullabies and tender kisses, she has moved on.

The personal servant to the Princess of Helios, the land of the Sun, Twilight enjoyed both rank, and knowledge. But it also means that when Princess Luna comes to visit her old friend, Twilight is given the task of tending her. The Princess has come in search of marriage, at the behest of her ruling Council. They demand an heir to ward off the potentially catastrophic attacks of the neighboring dragons.

Soon, Twilight will be tested and tried. She will be given the a choice between the life she has known, and the duty she is sworn to. But never, not once, will she forget.

For who can stop loving their mother.

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?

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 ?

This story is a sequel to House that Heartbreak Rebuilt

Heartbreak, after a roller-coaster ride of an adventure, is finally in a home of her own, and an honorary Cutie Mark Crusader to boot! Unfortunately, her time with the Crusaders and the Summer Readers Club is more than just social calls - it's also a one-of-a-kind opportunity for Equestrian germs.

It's Fluttershy's turn to teach Heartbreak a lesson in friendship, but it will be a struggle to get a real understanding of kindness through to the sickest, most stubborn tan mare in Equestria.

Ever since Twilight came to town, Mayor Mare's position as leader of Ponyville has been slipping. With her destiny overshadowed by the new princess on the block, it's time for the old gray mare to move on.

'I looked at the reflection, and the beast looked back.'

Viktoria had never seen the mirror before, now she wishes she had never examined it. With her body twisted into a strange and unsettling new shape she must become accustomed to her new equine form before finding a way home, and along the way also return her body to normal. Her body betrays her with each movement, muscle memory working against her. Will the newly encountered Flitter and Cloudchaser be able to help her?

Even with the new addition of wings to grant her flight and escape, Viktoria has never felt more confined.

'Others see me for what I am. I only wish for them to see me for who I am.'

( Thanks go to AkuOreo for such a lovely cover art! )

( Also, seems to have a Tv tropes page in the making! )

Shortly after the Changeling Invasion, a human wakes up in Chrysalis' body in the middle of the Badlands. Alone, hurt, and starving, she tries to make sense of where she is and what happened. Unable to remember even her own name, she struggles with her identity as she faces the trials of being public enemy to a whole species.

Or, you know, she doesn't. Identity crises are overrated anyways.
