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?

His appearance forever altered and his heart broken beyond repair, Chance struggles with thoughts and attempts of suicide.

Luna has a secret.

A secret that she's kept close to her heart ever since her return from the moon, a secret she's hidden for so long that she's no longer even sure if it's real. At least until it returns to haunt her, and she has no choice but to confide in Celestia and hope her sister trusts that she hasn't gone mad.

It's time to tell Celestia about the circles.

Through corporate greed and the pillage of the land, companies have marketed magic to the masses. Promising the gifts of Enhanced Magical Prowess in every aspect of your life and even non-natural born gifts through science and magical extraction. Gone are the blue skies and rainbows, long since replaced by brown and shades of grey. Dingy, an earth pony mare, blends perfectly into the landscape around her, largely unnoticed by many and always overlooked.

Being short of hoof with her finances, she submits to clinical trials for extra money to pay rent with Spark Industries. Little did she know that this simple cash grab would turn into such a tangled web of disaster. Leaving behind anypony she ever knew she is sent far into the future, where things were not what she expected at all.

Finding solace in the only voice she has, Dingy struggles to keep her sanity in a world with nopony in it and somehow manage to survive and find her way back home.
