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 Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

(XCOM/FiM Crossover)
(Sequel to Stardust, which I recommend reading before starting this. Fortitude Amicitia and Broken aren't required reading but are supplemental to the storyline)
(Gore tag for blood and violence)
(Alternate Universe tag because of the divergence from canon that Stardust has caused)
(Uses elements of Season 4)
(Coverart produced by the amazing Carnelian!)
(Many thanks to Arzoo, BradTheBrony, Vandenbz and Setokaiva for prereading!)
(As of 03/07/2016, the prereading team consists of Arzoo, BradTheBrony, Noble Cause and Metallusionsismagic!)
(Complete with it's own TVTropes page as part of the Stardust continuity. Could use some updating!)
(Character tags will be added as chapters are added!)

(Possible spoilers in the comments! BEWARE!)

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

'Caught' has been edited slightly. Re-read and try to spot what's changed XD

The crime rate in Canterlot was hitting an all time high, which was perfect for a young thief like Chase.

Unfortunately his fellow thieves started getting caught. And everypony knows what happens when you get caught.

You're taken to Celestia and interrogated in ways so horrible, so demeaning that the one caught is never the same again.

Chase knows this and refuses to let it happen to him.

For even if he is caught, he knows in his heart that he will never give up his life of crime. And nopony, not even Celestia herself can change that...

Right?

This story is just a bit of fun that popped up in my mind. Mostly because I wanna write Celestia in a good way for once XD

No possessiveness, no darkness, just a gentle, motherly Celestia.

I'm not sure about the tags, so if I'm missing something then tell me XD

It is the thousandth year since Nightmare Moon's banishment and she has returned. When the battle with Nightmare Moon goes awry, Twilight's friends and family must cope with the destruction left in Nightmare's wake.

Note: This story is based off of the picture giuliabeck's You Are Mine and Sparkle No More.

This story is a sequel to Days of Wasp and Spider

Believed dead by their creators, the ponies that will become Celestia and Luna have broken their mental conditioning and escaped into the wilderness. Here they plan the revolution that will free all ponykind, knowing that it is only a matter of time before their ruse is discovered.

Back in their underground arcologies, the ponies' erstwhile masters deal with the consequences of the escape, all the while unaware that something lurking at the bottom of space-time wants them all dead.

Inexperience is a foreign concept to Celestia. At least she thinks it is. Right up until the moment a rash decision leaves her with a student who is a dozen years younger than what she's used to.

Enjoy.

It's been said in prophecies that nopony will know the time or date the magic of Equestria that empowers its citizens would leave. I thought it was just superstitious nonsense written by ancient witch doctors. In a sense, they were right. But I would have never expected it to come like this. —Princess Twilight Sparkle, 05/05/1268

AU tag added due to the Cutie Mark Crusaders getting Cutie Marked.

This story is a sequel to Scion of Chaos

Five years after the summer in which the three had gotten their cutie marks, Scootaloo, Sweetie Belle and Apple Bloom, now young mares in their own right, decide to go on a quick summer vacation, all as an attempt by Sweetie Belle to cheer up a sad friend. However, the trip turns out to be more than they had anticipated.

Set five years after Scion of Chaos and An Emerald Treasure. For the sake of context I'd recommend reading both of those first.
