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!

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.

A human goes to sleep and wakes up in a pony's body and is falling from the sky. His adventure in a land full of color ponies has only just begun. But first, he must overcome a great challenge...talking to strangers.

As soon as he lands.

The cover art is mine.

When Nightmare Moon’s rebellion tore across Equestria, leaving a trail of blood and horror in its wake, Princess Celestia knew that merely banishing her sister wouldn’t be enough. Her army was too powerful, and too bloodthirsty, to be left behind without a leader. When she finally turned the Elements of Harmony against her, she didn’t just banish Nightmare Moon. She banished thousands.

Now they’re in a race against time, to find a way to survive in an environment so alien that every aspect of it is trying to kill them. They face suffocation, freezing, boiling, starvation, radiation, meteorite impacts, low gravity… the list goes on.

Nightmare Moon thought she should be the ruler of all Equestria. Now, in a world nopony was ever meant to survive, her abilities will be put to the ultimate test.

This story now has a hardcover! If you'd like one of your own, you can grab it here: https://starscribe.net/

Editing by the indulgent and patient Two Bit and Sparktail. Coverart by Zutcha.

Note: I intend this story to be as faithful to our current scientific understanding of the moon, and I’ve consulted for help with the aspects outside my technical purview. That said, I fully expect to make decisions that some may see as mistakes, based on their own independent interpretations.

I am a storyteller first, and I realize it’s likely I’ll eventually make a mistake, or an arbitrary decision to simplify the storytelling over accuracy. I’m doing my best here, but this isn’t a NASA white paper. Set your expectations accordingly.

This story was commissioned by Canary in the Coal Mine on my Patreon, feel free to contact me if you’d like one of your own!

This story is a sequel to Reformation of the Hives

Even though the threat of the jungle queens and Grogar have been diminished, life often times does not get wrapped up in a neat little bow. More troubles present themselves large and small. Our only hope is we keep passing life's constant tests, even when it is the last thing we wish to do.

(Pre-season 9)

If a better world was in reach for you, if you could reach someplace that was better if it meant leaving behind everything you've ever known, would you take that chance?

A new pony arrives in Ponyville, someone kind of odd, but nice enough. At the same time, Twilight's discovered a disturbance in the fabric of reality. But these two events couldn't possibly be connected...right?

Now with a TVTropes page! Please show it some love! Also check out the official side stories, Designing Intrigue, and Love and Barriers! (With even more in my stories page!)

(Please Note: This story was started before any season three information was available. All episodes in season three and later are non-canon for this story, which also means there's no Crystal Empire in this one. In addition, the promotional map released close to the beginning of season three was also not available and is not compatible with this story. While the OC tag is active because there are OCs in the story, they're really just supporting characters. The focus is on Twilight.)

Also be sure to check out the Rites of Ascension Expanded Universe Group! We're working to develop the resources needed for other authors to try their hand at writing stories set in the Rites Universe!

The Book Two cover art was created by the amazing Silfoe! The original cover art can still be found at Violet Squiggle's deviantArt page.
