A horrible Cataclysm has turned all of Equestria into a Wasteland of barren ash and twilight desolation. The Sun and the Moon have been destroyed. Everypony has died--including Princesses Luna and Celestia. But one pony miraculously survives; she is a lone wanderer, the last of her kind, surrounded by menacing creatures that hate her. She navigates the Wastes in an airship and scavenges off the blighted landscape to keep herself alive.

Then one day she meets an old companion who grants her a gift, the chance to go back in time to the warm and sunny days of Ponyville, where her dead friends live in happiness. How far will the last pony venture into this joyous age of Equestria, even if she fully knows that there is no way to change the horrible fate of everypony she loves?

2013 Edition: Smaller Chapters, Better Grammar, and a Few New Scenes

(A shout-out to Vimbert, pre-reader and gentlecolt)

Principal Celestia has accidentally fallen through the mirror into Equestria, and it may be a bit before she can go home. Until then, she has to learn to cope with a strange world, in a strange body.

At the same time, Twilight has to figure out how she can help her new guest while keeping Equestria from freaking out over the presence of a second Celestia, and Sunset Shimmer has to figure out how she is going to make amends with those she had left behind in Equestria, while keeping an eye on her Principal.

Disclaimer: Since I wrote this description ages ago before I even knew the plot, the story is mostly pure comedy in the beginning, with eventual Sunlight and Chryslestia shipping!

The past always comes back to haunt the present, there is no escaping the inevitable. For decades, Celestia has kept a secret from her student. A secret she made out of pain, and through pain will be revealed for all to see; for Twilight Sparkle is the secret daughter of the Sun.

Now, there will be consequences.

Consequences, they come in all shapes and sizes for every decision. For every action there is an equal and opposite reaction. These words are lessons that Princess Celestia should know, bits of wisdom she practices in her rule of Equestria. How is it then, that when faced with a decision, she chooses the one that would inevitably bring the most pain? How is it that she couldn’t bear being recognized as the mother of her child? And why? Twilight Sparkle is about to find out.

A thousand years ago, Princess Celestia banished her sister to the moon, that much we know. What wasn’t known, and what Celestia kept secret was that before her banishment, Luna had given birth to a foal. Now a thousand years later, as Nightmare returns to Equestria to bring about Eternal Night.

Twilight Sparkle, protege of Princess Celestia, struggles against the tyranny of this ancient foe. But how will she be able to save herself and her friends when the truth of this ancient legend crashes down upon her? Twilight will have to confront herself...and her heritage.

This story is a sequel to Memory Pending

The story of Moon Mender continues after his dream of an ending ceases. He continues his struggle to belong in a world so far divorced from the only other experience he can remember, but as an outsider of truly alien mindset, will he ever be able to find a place in Equestria? More importantly, will the life he left behind give up on its death grip so easily? The most important thing to remember is that things are rarely as they seem and sometimes, some things are better off forgotten.

This story is a direct sequel to Memory Pending. Without having read that, this story might be a little strange to most, which is frightening considering how strange it is already. It can be read as a standalone story of course, but you won't get the most out of it.

Further, I’m fully aware that not everypony enjoys more mature themes, so any scenes containing things of an M rated nature shall only be released in a separate story when the time comes. This story deals with more mature themes on a whole, as a warning. This version will do its best to censor the really sensual or graphic content out, of course.

Last but not least, this story has reached this final format through combined efforts of not just myself, but many a helpful pony along the way! Here’s an abbreviated list of those involved and the rolls they played:
Kiroberos – Author (Obviously)
Julia – Editor (Corrections, Grammar, and Flow)
Azu – Beta Reader (Corrections, Flow) (Until Chapter 35)
ExplosiveBrohoof – Beta Reader (Grammar) (Until Chapter 22)
Muffinking – Beta Reader (Corrections, Grammar) (Until Chapter 22)
All of my readers for being amazing, supportive, and best of all, enjoying the world we read and write about.

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.

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!

During a traumatic event, an outsider finds himself flung violently into Equestria. His physical form is warped into that of the inhabitants but will his mentality follow? And even more importantly, will anypony truly accept him for who he is? Take a journey alongside this inexperienced youth as he finds himself in a strange new world with very different customs and tries his hardest to find a place for himself where he didn't before. A pity he can't even remember his name...

Okay, the basics. It's first person almost entirely. Very, very long chapters. I try to wrap them up around twelve to thirteen pages but a few slipped over that, especially towards the end. I'll release them slightly stagnated, as I'll be making final revisions as I go. Character tags are NOT final. I'll add more main characters as they show up in each chapter. Expect an update one or two times a week, probably. I adore reviews and structured, constructive criticism. Even if you just want to say you like it, that's fine too. :) I write stories to entertain peoples, so any evidence I get that it's working will encourage me. I hope you enjoy the story!

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. Along the way, she learns that some friendships can be very, very strange.

Book 1 of the Alicorn Adventure series.

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.
