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?”

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?

This story is a sequel to The Three Sisters: Extended Family

A story of The Three Sisters Universe

Families are like fudge — mostly sweet with a few nuts. ~ Unknown Author

Chrysalis' daughters are serving their community service in Ponyville. Nothing can go wrong. Right?

Unless they all have their own agenda, and surprises keep piling up, complicating matters further. But anything to broker peace between the Changeling Nation and Equestria... right?

Now with a TV Tropes page! Warning: Will Contain spoilers.

This story is a sequel to Families

Third in the Nuptialverse...

Twilight Sparkle has done much for Equestria. If it weren't for her, Equestria would be destroyed three times over by now.

So what happens when she has to leave? What happens when she and Spike are forced to depart from Equestria in order to fulfill their duties? And what happens when there's still important things at home to do?

Applejack, Rarity, Pinkie Pie, Fluttershy, and Rainbow Dash now have to get along without the one who leads them. All of Equestria is counting on them. Can they do it?

AU only post-season 2, since the basic idea for this fic was created long before it aired. Events similar to season 3 have happened, all of which will be revealed. Strongly recommended you read Post Nuptials and Families first.

This story is a sequel to Lost into Shadow

Twilight has failed, or rather, she has succeeded. Her darkness is her power, and together with her husband, Queen Twilight has a new plan for all of Equis. The black castle rises to greater power than has ever been seen before. War is brewing while alliances are forged and others are broken. The days of harmony are dead and gone, and all the world will be forced to mobilize against the might of the Nightmare Hordes. Will they prevail in the faces of Wrath and Despair? Do they have any hope of someday returning to a time of peace and love?
....
........
Not a chance, because in Chapter 1, Hope dies.

Twilight had reached her peak, she was at the happiest point in her young life. The day of her coronation as Equestria's newest princess had finally arrived. Then the unthinkable happened, Sombra appears in the throne room alive and well demanding his chance to be reformed by pony society. The unthinkable happens again, when his wish is granted, spearheaded by none other than Princess Twilight herself. Will Sombra's nefarious plans bring her to ruin, or will she succeed against all odds? Only time can tell as it reminds them both that plans have a way of changing all on their own.

It has been twelve years since Twilight Sparkle was shrunk to 1/100 of her original mass to minimize the damage caused by her uncontrollable surges. Twelve years of struggles, challenges and hard work as Princess Celestia’s student, in which the tiny mare found the joy and excitement of facing everyday adventures of a huge world.

One year before Nightmare Moon’s return, Princess Celestia sends her tiny student to learn about pegasus magic from professionals, the Wonderbolts themselves. Much to the princess’s pleasant surprise, Twilight forms strong bonds of friendship during her one month of studies with Soarin' and Spitfire while the Captain of the Wonderbolts, Impressed by Twilight’s talent in magical surgery after the crystal mountain incident, offer her a job as one of the Wonderbolts’ medics.

While Twilight accepts the offer with Celestia’s blessing, provided that it would not last longer than half a year, the other Wonderbolts are not too happy with this idea. Will Twilight manage to win their trust, and what kind of adventures and challenges await her so far away from her home in Canterlot castle? Only time will tell.

This is a sidestory that takes place in "Celestia's Tiny Student" between chapter 20 - "Camping Trip" and chapter 21 - "Birthday Party."

My name is Twilight Sparkle.
I am three hundred and seventy five years old.
Except for Spike, all my friends are dead...But not for long

Betrayed by Celestia, and isolated in her castle with only Spike for support, Twilight Sparkle enacts a powerful spell to reincarnate the element bearers through her own body.
Her friends will be reborn, and, with the trials of being a mother to her friends ahead of her, an unraveling secret from the past following her at every turn, and the possibility of a brand new life so close in reach, Twilight just might be reborn too.

In the far reaches of Canterlot Castle, high above in the towers lived the archmage. Everypony knew her, yet few had met her.

Twilight Sparkle sighed, having teleported away another noble seeking favors before reaching the top of the stairs for the second time today. They never learned. As the archmage, she already dealt with political squabbles far too often without inviting them into her home. Aside from personal favors for Celestia, she did what was required of her position and then returned to seclusion and research.

The nobility grumbled that no archmage should be a commoner, and Twilight’s disrespect toward them proved it. Each and every time they were forced to bow to her, they hated what they saw: the position, the status, the deference.

Was she not powerful? Was she not great?

Twilight, now reading through dusty scrolls and long forgotten tales, wrote in her notes — notes gathering dust of their own. A brief thought flashed through her mind.

Am I not powerful? Am I not great?

And then Twilight picked up The Tale of the Royal Pony Sisters.

Defunct side stories told in Across the Boundary. They can still provide a little context, but when in doubt, the main story here is canon.

Cover art provided by Lafiir

Twilight Sparkle finds herself inside a cocoon in the throne room of Canterlot Palace along with her friends and many other ponies. She is thrust into a dream world by Chrysalis who is feeding on the feelings of love and friendship she and the others will experience in their alternate realities. In her dream, she finds Princess Celestia, who has been able to cross between dream worlds. Twilight and Celestia must now travel between dreams in order to awaken their friends and stop Chrysalis. However, some dreams are not as happy as they expected, and some secrets held in the subconscious may be better left unawoken.
