Prince Blueblood thought the Grand Galloping Gala was over. He thought he could just go to sleep and put it behind him. He never expected to be reliving the same disaster of a day, over and over... and over.

Thanks to all the people who wrote the page and all the people who gave me a little wakeup call and comment to become aware of that fact! You can't see it, but you guys put a real smile on my face tonight.

Also, recently, extra thanks to RD Dash for giving TBNE a thorough editing. I've updated the fic accordingly (7.11.12)

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

Three Nights in Manehattan, a sequel
Hardcover Print-on-Demand Order Page

As a child, Daphne knew of a world where magic lived, where an immortal princess reigned over a beautiful kingdom, and longed to journey there beside Leit Motif, the filly she'd grown to love in the woods behind her home. But one day, when she needed her most, Leit Motif was gone, and she never came back to show her the way. As she grew, she put aside her childish dreams, and taught herself to believe the lie.
When forces beyond her knowing take her sister Amelia, though, she discovers that her childhood fancies were entirely too real, and is thrust into a journey that will take her back to that land she longed for, back to the childhood friend she'd abandoned, and to worlds she'd only dreamed of.

PresentPerfect's Review

This story is a sequel to Dusk's Dangerous Game

Twilight Sparkle, known to all but the three Goddesses as Lady Everstar, the Evening Sage, has ruled over her kingdom for nearly five centuries with all the wisdom and grace of which she is capable. Her lands are wild and exciting, the prospects good for those with brilliant minds and daring hearts. But now something has changed in the Evening Kingdom, something has changed the balance of power so profoundly that even Twilight herself cannot tell how events may unfold.

Across the ocean, an ancient evil is stirring, its dark hunger can finally be realized. Its servants are many, brutal, and cunning. They are found among the lowest of lows, and the highest of highs. With the balance of power so disrupted, it is at last time for their shadowy plans to come to fruition, to cast off the darkness and strike against the night.

It will take the power of goddesses, magic both familiar and ancient, and the most unlikely of heroes to save not only the Evening Kingdom, not only Equestria, but the entirety of Creation as we know it.

Sequel to Lines and Webs and Dusk's Dangerous Game. Knowledge of the previous stories is not needed, but reading them is, of course, encouraged.

Followed by Courts of The Magi.

This story is a sequel to The Celestia Code

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!

Limited Liability is a changeling with a very routine life. He works at a bank. He lives with a marefriend. He goes through every day making sure he isn't discovered.

At least, that is, until the day that the hive has planned to invade Canterlot. On that day, his love runs out, and his disguise fails. Trapped in public with a chitinous body for all of Equestria to see, Liability has to find a way not only to survive, but to avoid ruining an invasion years in the making. Along the way, he learns a very interesting lesson about the ponies around him.

Written for the Equestria Daily "Outside Insight" contest.

Sparkler has a secret that she's hidden from her mother for many years, a secret that would destroy her if she ever found out. But, with the help of her... special friend, Sparkler decides that she can't lie to her mother anymore. So she sits her mother down and reveals her most shocking secret.

My life was simple. I used to be a cellist, of Canterlot's pride and nobility, and a very happy pony with where I was. I should say I landed myself here; it was nopony's fault I agreed with Vinyl on this ludicrous idea. I will, however, blame Vinyl for the guards outside. And for my doctor. And for Princess Luna.

That's all on her.

So, in the off chance that we don't get out of this room in (literally) one piece, my name is Octavia, beginning log: one.

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.

Waking up on a rooftop on Nightmare Night alone wouldn't have been so jarring for Eyewitness if it weren't for the dead body. Struggling with the harsh wake up call, and the arrival of the mysterious 'guardspony' Chocolate Malt, she must help him solve the murder while keeping her own secrets intact.
