This story is a sequel to Seven of Six: A Screaming Butterfly

Twilight Sparkle is a unicorn prodigy, her special talent of magic allowing her to wield all manner of the arcane arts with ease. She is an SGU graduate, has connections with the Royal Guard, knows Princess Celestia, and is a mother to a juvenile dragon.

She's also apprenticed to Discord, Lord of Chaos and Disharmony.

And he has a mission for her. A fallen alicorn named Nightmare Moon will soon return to bring eternal night and assured death to all the world. It's up to her to retrieve the Elements of Harmony and stop her.

Join her as she explores a familiar town, befriends familiar ponies, and completes a quest that's as old as the fandom itself, but with a twist.

A retelling of the pilot episode Friendship is Magic, but set in one of Starlight's alternate timelines.

This story is a sequel to Rainbooms and Royalty

An alternate universe re-imagining of "Friendship is Magic." Rainbow Dash is the personal protege of Celestia, ruler of all Equestria. Follow her through the events of the 1,000th Summer Sun Celebration and the return of Nightmare Moon! (A significant rewrite of the "Rainbooms and Royalty")

Since her banishment, Nightmare Moon has planned her Revenge. Now her 1000 year imprisonment has ended and she is out to take what is hers.
However the young Arcane Mage, Twilight Sparkle, will do all she can to stop Nightmare Moon, but Nightmare Moon is not alone as she has formed a small but powerful army.
However Twilight is also not alone, as five other mages, Applejack The Paladin, Rainbow Dash The Elementalist, Fluttershy The Druid, Rarity The Enchantress & Pinkie Pie The Jester will stand by her.
Can they save Mystika from Eternal Night? What will Nightmare Moon employ to achieve her goal? And will Twilight learn the Magic of Friendship

"People assume that time is a strict progression of cause to effect." What they don't realize is that if the slightest detail of a key point is changed, it alters history, and the future, forever! What if Luna hadn't grown jealous of her sister, in fact, what if Luna was a different person altogether? Would she have been trapped in the moon, would Discord have been turned to stone, would the Crystal Empire still be standing; would Equestria be very different? We're about to find out!”

The day of the Rainboom affected more ponies than just the canon Mane Six. Almost ten years later, Princess Celestia sends her personal student Twilight Sparkle and one such affected pony to Ponyville. Meeting four others, they must work together to achieve what Princess Celestia could not: defeat Nightmare Moon and save the long-lost Princess Luna from the monster she was trapped within.

It's also a shameless excuse for me to partner Twilight with five of my favorite ponies. Welcome to the Differentverse.

What if Equestria wasn't all sunshine and rainbows? What if the lands were wild, untamed, and ruled by powerful (and corrupt) nobles in the names of distant kings and queens? What if magic belonged not to every unicorn, but only to the privileged (and persecuted) few?

Camaraderie is Sorcery is a dark fantasy retelling of the story of Friendship is Magic. In this Equestria, the land is divided into kingdoms hungrily eyeing each others' lands and resources. This is a world where peasants are born, work, suffer, and die without their overseers shedding a tear. It is a world where bandits and monsters occupy both the wild places and the civilized ones (but in different forms). This is the world where Twilight Sparkle lives. Cant'r Laht, a shining city perched on the edge of a mountain with more nobles and mages than it knows what to do with, has been Twilight's home her whole life. Now, as the one thousandth summer solstice of the Fourth Age approaches, she will leave Cant'r Laht and depart for the tiny hamlet of Ponieville, where five companions await her. These Brave Companions, as the ballads will come to commemorate them, are already bound by destiny, though they do not know it yet. For who would ever imagine that a sorceress, a farmer, a Hunter, a blacksmith, a druidess, and a baker would ever become comrades with the strength to stop the end of the world?

Author's Note: I drew inspiration from several dark or realistic fantasy sources for the world of Camaraderie is Sorcery, but the most influential was the world of Andrzej Sapkowski's Witcher novels and CD Projekt RED's video game series of the same name.

The Elements of Harmony: Equestria's most powerful Magic, and the greatest Magic of all is Friendship. But what makes Friendship possible? What are, as one might say, the Elements of Friendship?

Starlight Glimmer seeks to stop an ancient evil, and if she is to succeed, she's going to need five other ponies to help her find out . . .

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 is Equestria. But something went differently this time. The Everfree is even more out of control, and has become a breeding ground and nesting place for thousands of dangerous creatures. With so many new threats constantly changing, evolving in the darkness, no one knows what the next monster could be capable of. In such a world, the Unknown means Danger.

Meet Pinkie Pie. She's an earth pony who likes parties and making everyone smile. She's very, very good at it.

That's a bad thing.

You see, some of the things she does are... strange. Unnatural. Sure, parties may be her special talent, but that doesn't explain where she got a cannon that can decorate a room. And it doesn't stop at parties. There's something unnatural about that mare. No one can explain it.

Pinkie Pie is an Unknown.

Unknowns are dangerous.

Princess Celestia has taken the poor pony under her wing, and raised her away from unfriendly eyes, allowing her to live what approaches a normal life. Soon, Pinkie will be reintroduced to the world at large, starting with a little town called Ponyville, on the day of the one-thousandth Summer Sun Celebration.

Let's see how that goes.

All it takes was one decision to throw an entire world into disorder.

When Twilight Sparkle decided to go to Moondancer's party instead of the Summer Sun Celebration and try to catch a late train into Ponyville later, Celestia found herself completely unprepared for Nightmare Moon's return. Unbeknownst to her, one of Twilight's friends, Lyra Heartstrings, did go to Ponyville. There, Lyra tries to fit in, and is thrown headfirst into a world full of new friends, secret agents, prejudice, unrequited love, very requited love, conspiracy, bitterness, regret and the end of all of Equestria.
