Twilight wakes up in a hospital near the border of Changeling country, but something about her is...off. She remembers nothing of her adult life, in fact she doesn't seem to be acting like an adult at all, and she seems to be juggling a bit of an alter ego. An evil alter ego. Maybe, when she took in the magic of the princesses, she took in a bit more than magic.

What if Spike had been home when Tirek destroyed the Golden Oaks Library, and had been killed? What would Twilight do? More importantly, who would be able to stand in her way and stop her when she delivers retribution to those who have caused her to lose everything? After she defeats Tirek in combat, she turns her focus on all of Equestria, and those whom she lays blame upon for the death of one she held dear to her.

With the combined powers of all the princesses inside of her, and a deep anger within her soul, can she be stopped, or will all of Equestria answer to her wrath?

Written for the Twirant's Kingdom Competition in the Tyrant Sparkle group.

What is a Moral Event Horizon, really? Where is the bar set? Is it really a Point of No Return?

The Elements of Harmony are scattered, broken, or dead. The enemies of daylight are powerful, strongly connected...Friends. But there is hope. Trixie has created a spell that can bring their dead friends from another world, giving the Elements a chance to save this one...Before Queen Nyx goes too far.

Contains TrixieJack and some unrequited TwiPie. Based on Past Sins, created with Pen Stroke's permission. Art created for this fic, by BB.

All magic vanished from the world when Discord fell. Along with it, the might of the unicorns and alicorn princesses dwindled. Even the Elements Of Harmony lost their potence and were lost in the sea of time.

Left without the guidance of the alicorns and the magic of harmony, the ponies soon raised Equestria to a country ruled by science and industry. But still, some remain who dream of magic.

As the mysterious beast Magia threatens the world, a sickly filly named Twilight Sparkle and five friends take it upon themselves to delve into the caverns beneath Canterlot to find the burial ground of magic, the Lunarium.

This is an ongoing Rewrite. The story in and of itself was finished in April 2013 but needed some massive editing. This new version features all new scenes, better descriptions, less mistakes, 3D-Effects, and a gratis code for the DLC-Character "Emo Pie", which on any other occasion would've been a pre-order bonus only.

Or something.

Also thanks to everybody who helps/ed editing this story, no matter if you did only help me with one chapter or all. Thank you for turning this rewrite from another mess into a brilliant story!

Cheer up, Twilight. It's not every day somepony changes species. In fact, no pony has ever changed species. It's something new and you like discovering new things. Granted, Equestrians don't like new things, especially things that fundamentally alter their government. So maybe there is reason not to be happy after all.

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.

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!

Twilight has spent the last two decades fighting against the dark forces which threaten the peaceful kingdom of Equestria. As a Royal Alicorn Princess, she has no choice in the matter. She is the greatest magician Equestria has ever known, but it has all come at a cost, both physically and mentally. She resents her friends for the happy, carefree lives they've been able to lead. Somepony will have to breach her walls of isolation and sorrow before she does something foolish.

Years have past since the changelings were driven away from Equestria, giving room for peace and love. Suddenly, Twilight is captured in the middle of the night, and is brought to the hooves of Queen Chrysalis. Seeing that she has captured the element of magic, she is determined to gain her revenge against both Twilight and anyone that has ever wronged her.

Using her dark magic, the queen transforms the unicorn into a horrifying creature. Will Twilight hold on to her sanity, and more importantly, her devotion to friends?

Or will she slip into the darkness, and lose all hope.

Props to chaos2012 for bringing me this idea. The story is mine though

Evilpresident is also onboard as a Pre-reader.

Okay, new cover art! This time it was actually made for the fic, so credit goes to BronyInvestigator
I cannot thank him enough.

Twilight Sparkle never was a Unicorn and she didn't even know it.
What happens when her true heritage comes to light? Will she willingly embrace it? Or will she be forced to?
