After transferring to Canterlot High, Twilight Sparkle realizes she has a crush on Sunset Shimmer. Being the analytical type, she develops a plan to capture Sunset's heart...using the scientific method.

Sex tag for mild sexual references.

For years, Twilight Sparkle and Queen Chrysalis have been at each other's throats. Both have experienced victory over the other, and both have experienced defeat. Out of all the creatures in Equestria, none despise each other the way the pony Princess and changeling Queen do. They seemed destined to remain locked in battle forever, or at least until one is finally dead at the hooves of the other. The cruel insults, the vicious loathing, and the powerful spells that have passed back and forth between them at each meeting have become the stuff of legend.

Imagine Twilight's surprise when she finds out changelings consider this dating.

And now they're married.

There is now a reading of the story on Youtube, which starts here.

Alternate ending to EQG: Friendship Games if SciTwi were a responsible scientist.

This story is a sequel to The Luna Cypher

Twilight sets out to learn more of the ways of the world, and soon decides that the whole planet is disorganized, insanely dangerous, and desperately needs to be fixed. And she's just the mare to do it... with a little help from her friends.

Also, there are sky-pirates!

Book 3 of the Alicorn Adventure series.

A few extra, slice-o-life chapters are here: On the Rocks

When Twilight Sparkle was just a kid, her best friend was a girl named Sunset Shimmer. Though their friendship had a bit of a rocky start, they quickly became inseparable, no matter how much everyone thought of them as ‘weird’. They were there for each other.

Were.

Years after the tragic accident that tore them apart, Twilight is determined to move on from her loss, and she sets off on an independent research project to investigate the strange happenings at Canterlot High. Little does she know that she will soon come face to face with what appears to be a literal ghost from her past.

In the year 2036 an asteroid dubbed "Apophis" struck the Earth and contaminated fifty percent of its water and atmosphere with an extraterrestrial pathogen dubbed "The SOL Strain." After two years, sixty percent of all human life was gone! With the world's governments struggling to keep their countries together; all seemed lost.

That is where my story begins.

My name is Chloe Cooper and I'm the only known human to be genetically immune to the SOL Virus. During the pandemic, I volunteered myself for experimentation. In order to keep me safe, I and three other humans were locked away in a vault deep within the Appalachian mountains. There these people, who I soon considered my friends, ran many tests on me and the virus, however after months without contact from above it was time to put the project to rest.

Cryostasis pods dubbed: "Cocoons" had been built in case we failed. 16,000 years later I awoke to sirens, signaling a whole host of problems.

And now? I'm the last of my kind.

Character tags will be updated depending on where the story goes

[I only know so much about the OC Twivine.This is the one who created her. Rating will either change to M or the next installment will be an M story. Tags added as I need them.]

Emerald Morrison didn't have the best life, but certainly not the worst. She didn't have the best grades, but also not the worst. But now? Now she finds herself as Twivine, an OC made by another brony. Problem is, she has no idea who Twivine is. She heard of Twivine, seen one or two fan made pictures but that's about it.

Somehow Twilight's magic surge brought Emerald or rather Twivine to Equestria and now she grows up (again), only this time in the Sparkle household.

08/29/2015 Featured? Thanks. Sure hope this isn't because of a short raise in the amount of views.

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.

There is now a Spanish translation of this story, courtesy of Spaniard Kiwi

The princesses gave their magic to Twilight to prevent Tirek from stealing it. As a result, they end up stuck in Tartarus.

Marvelous place, Tartarus. Really brings ponies together. The fact that things manage to go downhill here says a lot about the wonders of family and alicornhood.

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?
