Winter Aurora is a Lich. She didn't intend on becoming one, but now she can't help it. All she wants in her life is to be accepted by other ponies.

Part 1 of The Winter Memoirs

Note: This story will rapidly fluctuate between extremely sad, and absolutely hilarious, depending on the mood I'm in when I write. In addition, even I have no clue where this story's going, so I may be adding character tags over time.

Now with a prereader! Servo in Chapters 17, 18!
Now with another prereader! Pixel_Spark in Chapter 18!
Now with a group! The Winter Memoirs
Now with a needlessly added extra line!

Amazing art created by Pixel_Spark

A thousand years after the banishment of Princess Luna to the moon along with all the Imperialists who swore allegiance to her, a complex lunar society has been built beneath the surface of Nightmare Moon's prison. In just a few decades, the despotic Empress of the Lunar Empire will have gained enough power to return to Earth and invade Equestria, transforming it into a dystopian realm of darkness. The only thing that stands in Nightmare Moon's way is the fulfillment of a prophecy, where the stars will aid in her escape so that the Elements of Harmony may exorcise her of her evil before she becomes dangerous enough to overcome her sister, Princess Celestia.

Enter Myrk, the former Captain of the Lunar Night Wraiths. Once the chief bodyguard to Nightmare Moon, he has since been branded an exile and traitor to the Empire. The Imperial Lunar Rune Guard hunt Myrk throughout the subterranean cityscapes of the moon, until he is forced to hide within the sarosian district of Tranquility deep below the outer laters.

Now, after having reunited with his half-sarosian lover, Choral, Myrk must embark upon a dangerous mission to deliver a captured piece of Princess Luna's magical essence to the lunar surface, in order to cast a beacon that will summon the stars and pave the path towards Nightmare Moon's righteous defeat.

This is an indirect prequel that takes place within the same universe as The End of Ponies.

This story is a sequel to The Celestia Code

When the monsters created by the dark crystal engine escape their prison, it's up to Princess Twilight Sparkle to deal with them. She gets help and advice from Princess Luna, but things don't go as planned. In fact, when a pony who relies on logic and rationality tries to navigate the stormy seas of emotional entanglement while simultaneously saving Equestria from a horde of evil creatures intent on destroying everything they encounter, nothing goes as planned.

Book 2 of the Alicorn Adventure series.

Goodreads Page
100% Approved by Twilight's Library!

The Badass Twilight tag applies more than ever, but please note the new tags.

This story is a fairly direct continuation of The Celestia Code. You might be able to follow it without having read The Celestia Code first, but it's better if you do.

The sequel is here: The Twilight Enigma

Most excellent pre-reading/editing done by the erudite AcademicPony and the dapper statoose!

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

This story is a sequel to The Cadenza Prophecies

Princess Flurry Heart inherited her mother's beauty and grace as well as her father's strength and bravery. The Empire couldn't hope for a better or more suitable heir to the Crystal Throne. Everypony in Equestria admires her and thinks she will be an ideal ruler.

They're wrong.

Young Flurry Heart has no interest at all in being a prim and proper princess, and would much rather have wild and dangerous adventures like her Aunt Twilight.

Book 5 of the Alicorn Adventure series.

Princess Twilight Sparkle discovers a centuries-old mystery hidden in the Royal Archives. Her investigation leads through layer after layer of deception and misdirection, setting her hooves on a path that seems to be leading to a mysterious secret.

WARNING: Major spoilers in the comments. Takes place several months after the end of season four. (Not a Da Vinci Code crossover, BTW!)

Do you see a dark tag? No, you don't. Not dark. Well, okay, there are a couple of dark-ish bits, but that's all. Not enough to warrant a tag. Speaking of tags, there really ought to be "Badass Twilight" and "Friendshipping" ones.

Sequels and side-stories (and more) can be found here Offprint and AO3, and a hardbound two-volume set of all that can be ordered from The Ministry of Image.

My editor for the first edition of this story was Gogito, and I can't thank him enough for all the hard work he did. My editor for the revised version was PresentPerfect, and he did a terrific job of getting the story into excellent shape.

THIS STORY IS BEING REWRITTEN. THEREFORE IT IS NOT COMPLETE.

My name is Seth Rogers. I'm a simple college student trying to get a degree so I can land a good job. However all of that goes out the metaphorical door when I encounter a strange man adorned in half-plate armor. Before I know it, I'm in an unknown land filled with ridiculous looking ponies colored every shade of the rainbow. Or all of them, in one case.
...
I want them to stay as far away from me as physically possible.

This is a Human in Equestria story with shounen elements. The twist is this: the main character, a bitter and troubled young man who doesn't believe in kindness or friendship, experiences the very same lessons that we have in the process of watching this incredible show. Can the ponies we all know and love help Seth become a better person?

Another thing that I must point out is that the show does not exist in the human world. Stay tuned, as character development is the goal of the whole story.

Book I: The New World: Chapters 1-7
Book II: The Meaning of Friendship: Chapters 8-19
Book III: To Canterlot: Chapters 20-33
Book IV: The Royal Wedding: Chapters 34-57
Book V: Forgotten Memories: Chapters 58-86
Book VI: The Return of the Crystal Empire: Chapters 87-End

There is now a Sequel: A Wilting Flower
