This story is a sequel to Memento Mori

I have seen the mare who does not sleep.

Shall I tell you about her?

(Written originally for the Writeoff Association. The Prompt was "Forbidden Knowledge".)

Twilight is beyond the title protege. Prodigies are merely brilliant. Twilight has surpassed most of the greatest mages in history before the age of thirty. Twilight's research has changed the landscape itself. She is a living legend who some whisper may be the greatest user of magic to ever exist... perhaps even an equal one day to the semi-divine princesses.

But Twilight's knowledge is not infinite. She has one final lesson to learn. Twilight must learn the Final Law of Magic.

Rainbow Dash hasn't been having a good time since Discord was defeated. Her supervisor suddenly thinks she can't handle a simple weather schedule. Her relay team all suddenly have a grudge against her. Something isn't right, and it's not limited to her. Applejack's family is watching over her like a jailhouse warden. Twilight is avoiding them all, visiting with strange ponies, and losing sleep on something she won't talk about. Pinkie Pie, and Rarity are both having problems they can't explain. And for Fluttershy, it's the worst of all.

Without Twilight’s guidance, 5 ponies have to figure out what happened to the town, and why their lives are so messed up despite Discord being long gone. Somehow they have to get Twilight to open up to them again, and accept help from her friends. But nothing they do seems to work right. They’re at a loss of what to make of any of this, until Rainbow Dash stumbles upon a truly chilling revalation, that throws into question everything the 5 of them have ever known.

When trouble calls, Dash wants an obvious goal, a big bad monster to defeat, but now the only thing she can see in front of her are all her friends.

This story is a sequel to Inexcusable

She looked just like Princess Celestia, except marred and broken. Her ceremonial barding had rusted slightly, and dirt matted her coat. Most noticeable was her hair; black streaks accompanied its usual multicolored luster. They looked like discolorations in an old photograph.

Worst was the scar across her chest. Her armor covered it, but nothing could hide what it meant.

The tarnished Celestia smiled at Luna. "H-hello, monster. I would say I am glad to see you, but that w-w-wouldn’t be quite accurate."

A big thanks to AlicornPriest for editing/prereading.

Every morning, Princess Celestia wakes up in terrible pain, and every morning, she chooses to endure it. Until one blissful day grants her the blessing of feeling normal.

Few things in her life have ever frightened her so much.

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

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.

This story is a sequel to The Code's Apprentice

Sequel To : The Code's Apprentice

The land of Equestria has been changed forever.

New monarchs sit upon the thrones of the Sun and Moon, the once almighty power of Harmony overturned to make way for a new Diarchy of Balance. Political unrest and turmoil have engulfed the land, and at the very center of it all, Princess Celestia - renamed Tia Sunbeam - seeks atonement for the crimes she committed in the name of Eternal Harmony.

With much of her power sealed away, Tia must live amidst the citizens of Ponyville as the world changes all around them. As Ponyville works to rebuild following the struggle between student and teacher, they must cope with the edicts of a new government determined to bring equality to all creatures, beliefs, and ways of life - even those that were long since banished to the dark places of the world.

Tia Sunbeam will struggle with her own deeply held convictions on the way the world should be, versus the way it will now become. She will face a truth she has long since denied, and realize the true meaning of Harmony. And perhaps, most importantly of all... She must make some Friends.

Oh, and go check out my new side story - Rise - It's going to become relevant here!
(character tags are not comprehensive! Some are being kept secret! ;3)

To be inserted into Equestria, it's a dream come true for anybrony!

Meet the ponies!

Have super awesome magical adventures!

Use foreknowledge to avoid all those silly pratfall moments without screwing things up and causing irreparable harm to the Mane 6...uh...hopefully!

And all for the low cost of possessing Princess Luna, denying her any real freedom or the ability to move on with her life since she's in your head and you're walking around as Nightmare Moon!

Yeah...there had to be a catch in there somewhere, didn't there?
