chapter 1 to 3 edited by fFillyphill

This is a Fallout Equestria (primarily) and Terminator crossover.

As the war between Equestria and the zebras pressed on, many members of the Ministries conceived of desperate strategies to end it through magical and technological creations of questionable nature. One of these was Project Infiltrator, a top secret project of the Ministry of Awesome. It's goal: to create a super spy that was the perfect blend of pony and machine. But just as its first subject was ready, the megaspells dropped, destroying Equestria and creating the Wasteland.

190 years later, Crystal Eclair awakens in a world of ruin and violence, completely clueless as to what happened to Equestria and herself. Her confusion grows into horror as she discovers that she is no longer a pony, but now a cybernetic zebra. With no other choice left, she sets out to find answers to her predicament. How will she handle the truth if she finds it? Will she find friends who can help her in a world that trusts no one? And what if those who have done this to her are still out there, eager for her to serve a new sinister purpose?

PS. This is not a Prequel to Broken Steel despite what a couple of websites that link back to this story say.

(Chapters 1 to 12 Edited by Alycorn~(CF), New Editor Double R Forrest. New description credit to Double R Forrest )

The most wanted mare in Equestria, Twilight Sparkle is the greatest thief in the world. As she follows in the hoofsteps of her grandmother, Twilight Twinkle, she's joined by friends and chased by family, all while trying to make a few bits!

An alternate universe fiction where Twilight Sparkle never entered Celestia's School for Gifted Unicorns. At least, not without a set of lockpicks. Gilda is her closest ally and friend, and a skilled marksman with her crossbow. And of course there's Rarity Belle, who can wrap Twilight around her hoof with a wink and a smile - and usually picks her pockets in the process. With friends like these, Twilight keeps one step ahead of Shining Armor and tries to get her hooves on all the bits she can carry.

Perhaps there's more to immortality than we first thought. Perhaps it's not about living forever, but merely escaping Death's icy cold hooves.

And by staying one step ahead of him at all times.

Twilight's power, along with that of Celestia, Luna, and Cadance, has been claimed by Tirek. Drunk on power, the demon-centaur is unleashing destruction upon Equestria, his reign of terror just beginning.

But there is hope. A crystalline chest, a gift from the Tree of Harmony, able to be opened by six keys. Keys which Twilight has now claimed the last of. All they can do is hope, hope that whatever is contained inside the chest is enough to stop Tirek.

And then something goes wrong ...

Note: This story is in no way connected with my other fanfics. It's very much a one-off in good fun.

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.

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.
