Rainbow Dash needs to hear the roar.

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?

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."

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 ?

Hi, my name is Markus.

I thought it was going to be a normal Sunday morning. Boy, was I wrong. Not even out of my bed I discover that I am now Rainbow Dash... and I'm still on Earth. In wake of my sudden change, I try to handle the situation with my knowledge gained from the fandom, my inner brony writer helping me along the way. However, as I soon find out, I'm not the only one with this problem...

Just a self-insert thing I started to get rid of a bout of writer's block. I don't care if it's liked or hated, so enjoy. Please remember, criticism is greatly appreciated, as is praise.

EDIT: For other stories in this universe, PonyEarthverse

It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

There is now a follow-up to this story: Sunflower - Side Projects
Sequel: Project Sunflower: Harmony

My name is... Or at least I think it is, Leslie. It might be Aurora Drift now, it's hard to tell.

One day the world of earth stopped being the mundane place humanity was used to, as a crack in reality spread magic across the world. Humans began turning into ponies everywhere, and for a while I thought that was what had happened to me too. But memories I wouldn't think belonged to me keep trying to prove me wrong. They aren't very good memories, and I think I caused the entire mess in the first place.

I haven't let anyone know yet, it's hard to accept for myself. Fortunately, humans are way too busy trying to find a way to adjust to the ponies amongst their society to try and find the one responsible.
