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.

After the defeat of Tirek, Equestria is safe once more, but Luna can sense that her sister is troubled. When Celestia retreats to the starry realm of ascension in order to look upon the past, Luna joins her to discover what is bothering her.

The situation has gotten ... out of hand.

Twilight Sparkle had thought that she'd cured Fluttershy of the bat influence, but it soon transpires that she was mistaken; now with their friend at risk of serious injury or death every night, Twilight and the others must do everything they can to keep her safe while they search for a more permanent solution.

If one even exists.

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?

Twilight Sparkle was presumed to be dead. Destroyed without even a body to bury, the young victim of a deadly magical surge that claimed the lives of many others along side her. More than a decade later, reports of a violent murder by a pony bearing her name are brought to Celestia and Luna's attention. A trail of carnage leading directly towards Canterlot's doorstep, brought by a pony who strikes without mercy. As Twilight approaches, in service to an unknown master, the Alicorn Sisters desperately try to uncover what happened all those years ago.

Princess. Alicorn. The pillar of all ponykind, against which so many ponies often judged themselves. Celestia hates having to constantly be these things, and it's past time for a break. Luna will watch over Equestria while her sister is gone, but taking a break from your duties and taking a break from how the world sees you are two very different matters. Enter Prominence, a quiet pony who nopony really pays much mind to. Perhaps because she doesn't exist.

Aided by this disguise, Celestia will find her peace and relaxation in the home of one of the few ponies who know Prominence's true identity: Princess Twilight Sparkle. But when Twilight begins to see Celestia as a pony, and not a princess, can she deal with the feelings that arise? And are the feelings for Celestia, or for a pony she knows is not actually real?

After several failed attempts at other friendly games, Luna and Celestia have finally found the perfect game to pass the time: poker. One night, drunk on cider, they decide to make the game interesting: If Celestia wins, Luna has to go on a date. If Luna wins, Celestia has to tell Twilight how she feels about her. Ante up.

Rated "Teen Sex" for some heavy wink wink, nudge nudge, and also booze.

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.
