Pincer is a changeling, a proud soldier of Queen Chrysalis. After the failed invasion of Canterlot, he finds himself trapped and at the mercy of Princess Celestia's Royal Guard. Believing that Celestia sees his species as nothing but soulless monsters, he prepares himself for the worst. The weeks crawl by, marked by an endless series of questions he will not answer for fear of endangering his friends and family at The Hive. As his nerves wear down and his interrogators learn just how ruthless he thinks they are, they have nothing to report but his belief that they will kill and destroy his kind without mercy.

Celestia steps in to prove him wrong, and what Pincer learns leaves him questioning everything he has ever known — but also gives him hope for what he'd never thought possible.

Now with a TVTropes page.

Twilight Sparkle had been looking forward to a quiet, relaxing day with a friend, and at first it seemed that Fluttershy could provide just that. But when Twilight makes a rather unsettling discovery about the pegasus – and her unusually sanguine appetite – the knowledge proves to be anything but relaxing...

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?

In the aftermath of her battle against Tirek, Twilight Sparkle is unwell. She wants more. She needs more. And she is afraid of what others might think of her.

But even in the midst of her growing despair that she has betrayed everything she stood for, she learns something about friendship and what it means to be an alicorn.

After the defeat of Queen Chrysalis, the changelings left behind don't know what to do. They eventually decide to seek the one who defeated their queen and make her theirs. What really goes on in a changeling's head? Can Cadence handle the vile creatures without prejudice? What do the crystal ponies think?

Twilight Sparkle has too much magic, and it will take her decades to learn to control it. Her spectacular loss of control during her entrance exam only proves that fact. She is a danger to herself and others.

After Sunset Shimmer’s disappearance, Princess Celestia needs a new student to bear The Element of Magic to defeat Nightmare Moon. With all of Equestria at stake, Twilight Sparkle…is not the pony she needs.

Princess Celestia seals Twilight Sparkle’s magic with the distant promise of one day teaching her.

But there are two diarchs of Equestria. Amidst a lucid dream, an offer is made.

“Hello, Twilight. Would you like to be my student?”

Twilight Sparkle and her friends have been model Equestrian citizens for years. After finally reuniting with Twilight, their lives were given real meaning. They’d become heroes; Equestria’s protectors, but the girls have always had bigger plans for the kingdom. Now the wedding of Shining Armor draws near, everything is about to come out into the open. Of course, there will always be those whom resist.

The changelings are banished, the day is saved! Yet a victory for one must be a defeat for another, and this particular victory has left one changeling stranded in Canterlot, alone and broken. A certain pink party pony is also alone in the Canterlot night, hiding her depression from her friends. She cannot, however, hide her feelings from a changeling. What will become of this unlikely pair?
