Twilight Sparkle was annoyed to say the least, when her mentor Princess Celestia dismissed her warning of the Mare in the Moon and assigned her to go to Ponyville to supervise the Summer Sun Celebration. 'Make some friends' she says.

The thing is, Twilight already had friends. Friends she's had ever since she got into Celestia's school for gifted unicorns, friends she's taken for granted for many years, friends who she just happens to bump into before leaving Canterlot and invite themselves along to the celebration.

Between the crazy ponies in this little town and the crazy ponies who call themselves her friends, she finds herself at her wit's end while being constantly sidetracked in trying to prepare for the fabled Nightmare Moon's return. After all, it's not like these old schoolmates of hers are going to be able to help prevent eternal night and the end of Equestria as they know it, right?

A lone vampire bat sneaks through the mirror portal and ends up in the human world. Instead of apples, it now craves something far richer. And unfortunately for Sunset Shimmer, she's its next snack.

Sunset can't remember any of her activities past sundown. The light hurts not just her eyes, but burns her skin. And she's thirsty.

So very thirsty.

It's up to the Rainbooms to save Sunset from herself before she drinks the whole city dry. Too bad Twilight Sparkle is her primary target.

Thanks to Saro0fd3monz for the inspiration!

Now with a TVTropes page!

Now with a French translation!

It's just been a few days since the friendship games, but something drastic has changed. The solar system of Earth isn't what the inhabitants of the planet are used to. Plus there are two teenage, high-school students, who control the most important objects in the sky.

Welp.

Now on TV Tropes.

What if the confrontation between Sunset and the Dazzlings in the hallway went a little differently? A "What if" scenario, with Sunset Shimmer puts her darker side to good use.

Midnight Sparkle has destroyed everything, leaving her and Discord.

But now that she's consumed all of existence, what's left?

Crossover of BioShock and My Little Pony.

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?

To celebrate the release of this sequel, I created a group called “Twinyverse” for all fans of this story where you can talk about it and track all side stories with ease.
The Twinyverse Group

For almost a thousand years, the immortal Nightmare Moon has reigned over Equestria as Empress. To the average pony, Nightmare Moon is an overarching enigma whose rule is absolute and whose wrath is terrible. But to Twilight Sparkle, who as an orphan has never known her parents, the Empress is something else entirely. When the young unicorn is brought under the royal wing as an apprentice, she learns a great deal more about the supposed tyrant than she ever knew. But as Twilight is introduced to life with her new mentor, she is thrust into a world of political intrigue, conspiracies and secrets. Secrets that were never meant to be revealed. As allies and enemies plot against the very peace of the nation, will Twilight fall prey to the perils of her new position? Or will she prosper and find in Nightmare Moon the mother she never had?

My eternal gratitude to my editor, LordOfTheWrongs, without whom Night's Favoured Child would not be the story it is today.

Now with added TVtropes!

Being the Princess of Equestria is busy work. Luna would know. She raises the sun and moon everyday, looks over the dreams of her beloved subjects, and, well, runs Equestria. Now, in addition to all that, she must find herself a protégé, before her sister's banishment ends!

But, that isn't the problem. The problem, is that three particular fillies stand out for the role!

Who will she choose? Can these three fillies become friends? Who will become Equestria's future savior!?

I guess you'll have to read to find out~!

First story of the Trio-verse.
