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?

Which will fail first Celestia's sanity or Equestrian Democracy?
*Part of Mother's Universe*

Days after Tirek's near-takeover of Equestria, The Great And Powerful Trixie travels to Ponyville, intent on settling her rivalry with Twilight Sparkle once and for all. No trinkets to fudge her abilities, no megalomania to apologize for -- just pure and simple magician's honor!

Upon her arrival, however, she quickly learns that the information she has on Ponyville -- and Twilight -- is more than a little dated.

This story is a sequel to Celestia's Twilight

We all know the story. One thousand years ago Princess Celestia was forced to banish Nightmare Moon to the moon to save all of Equestria, but what if Luna had been hiding something from her sister, scared of how she would react? When Luna had no other choice, she cried out for Celestia and Celestia came. For one thousand years, Luna wondered what happened when Celestia left; now she's finding out...

But is it already too late, or will Luna be able to take the role she had so long dreamed of? The dream of being a mother?

The past always comes back to haunt the present, there is no escaping the inevitable. For decades, Celestia has kept a secret from her student. A secret she made out of pain, and through pain will be revealed for all to see; for Twilight Sparkle is the secret daughter of the Sun.

Now, there will be consequences.

Consequences, they come in all shapes and sizes for every decision. For every action there is an equal and opposite reaction. These words are lessons that Princess Celestia should know, bits of wisdom she practices in her rule of Equestria. How is it then, that when faced with a decision, she chooses the one that would inevitably bring the most pain? How is it that she couldn’t bear being recognized as the mother of her child? And why? Twilight Sparkle is about to find out.

Twilight is invited to Canterlot to compete with some of the greatest magicians in the world for the Moonstone Cup, a prestigious award for the most powerful and skillful magicians, unicorn and otherwise. Can she win? What sort of competition will she face?

Celestia had always thought she'd reached the pinnacle of fear when she fought against some of Equestria's greatest enemies.

As it turns out, however, nothing compares to explaining to Twilight's parents that she's in a relationship with their daughter.

Collab with The Abyss (Chapters 1 and 2)

Proofread by Neko Majin C and edited by The Abyss (Chapters 3 onwards)

Twilight Sparkle has always ignored Hearts and Hooves Day, seeing it as just another normal day with extra chocolate and the occasional broken-hearted friend to comfort. But when Rarity convinces her that not having a date during the holiday is contrary to proper princess protocol, Twilight rushes to do everything in her power to live up to the expectations presented to her.

There’s just one problem, though: Twilight has never been on a proper date before.

After a few rather disastrous attempts to find a date in Ponyville, Twilight goes to her mentor in Canterlot in a last ditch effort in the hopes of finding the answers she seeks. Princess Celestia, however, may have something more for her than either of them had anticipated.

For as long as immortals have walked the planet they have had their own culture, rituals, and traditions. Of all these, the most sacred by far is the Bonding of Immortals, after which mortals modeled their marriages. Today Celestia and Twilight will take part in the Bonding of Immortals.
