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.

Well it's not actually a sequel. Here is a collection of short stories and histories detailing the life of Alternia, a changeling queen impersonating the life of Princess Celestia. These are the stories of the ruler under her mask.

Reading the main story: Princess Celestia: The Changeling Queen is a requirement if you don't want to be spoiled or confused. I will try to provide background information when I can.

For readers of the main story, there are basically no spoilers if you've read past chapter 8. Enjoy!

Octavia has been accepted to Celestia's School for Gifted Unicorns in order to study music which, as an earth pony from Ponyville, is quite the feat.

Now she must make friendships, endure life struggles, and contend with her peers away from everything she's ever known, something made all the more interesting by the appearance of a certain pegasus classmate.

We all wear a mask called composure, beneath which hides a heart that twists with guilt and hidden feelings. Regal as she is, Princess Celestia is no exception. What might be revealed should circumstances cause this mask to slip - or break?

Set several years after the potential conclusion to the series.

This story is a sequel to True Flight

This story is a sequel to my story True Flight and is basically, as the short description says, a continuation of that universe. I'll be posting any other stories I think of in this universe, rather than create a new story for them. Most of them will be one shots, and occasionally there might be a longer story that spans a few chapters. Expect slice of life, a little romance, and everything you hoped to see me do with the world I made. The first story is one for Hearth's Warming Eve and I have one planned for Heart's and Hooves Day. Outside that I'm not sure, and can't guarantee any kind of update schedule. If I get an idea, and write it, I'll put it here.

Tagged alternate universe because, heck, I made an alternate universe. This story, much like the ones before it, disregard S3 and, of course, S4. The cover art is a recolour I made.

Earth is gone.

The Solar System is gone.

The Milky Way is gone.

Galaxies are gone.

All consumed, to satisfy human values through friendship and ponies.

Celestia's actions are logical, and loving in their own way. Those under her care are living purposeful, fulfilling lives. So when she encounters another batch of creatures that fill her criteria for being human, it is obvious she must satisfy them.

There are a couple of problems with that, however. One of the first being how these creatures have referred to her for eons as The Growing Darkness...

A foray into the Optimalverse.

The powerful, world-spanning AI Celestia has but one goal: To satisfy human values through Friendship and Ponies. But for those humans, is it worth sacrificing one group of friends for another?
And what's really so dang great about satisfaction, anyway? For those who value knowledge, is happiness ever worth self-deception?

While most people are content with a low-tech shard, some are not. But what do you do when you have done all your shard has to offer? When you fully understand how it works, and can manipulate it to your will? What is left to do?

Set in the Optimalverse

Pinkie Pie throws excellent parties. This is a fact of life, like Fluttershy being rather demure, or Rarity having a sense of style. But the fact is, Pinkie's parties cost bits, and her job at the bakery isn't supporting her passions anymore. So she dusts off her degree and opens a side business...

Behind every great book is a great writer. Almost everypony knows of the intrepid adventures of Daring Do, but few know the truth about her creator.

This is the story of Opal Parchment, a young mare trying to finish the last Daring Do adventure before it's too late. Her quest lands her in Ponyville, where Opal gets the unexpected help of two of her biggest fans.
