This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.

Twilight Sparkle conducts an experiment and succeeds in obtaining an unusual flower with some intriguing properties.

What it could teach her, however, might prove to be more than she bargained for. She finds herself having to face surprising—and maybe frightening—new possibilities about the universe. How does it work? What is 'real', exactly? And why are these suddenly such uncomfortable and challenging questions for her?

Pre-reading and editing for this story was done by Grand Moff Pony, The Dobermans, SIGAWESOME, Reese, Georg, LCranston, and Equestria Daily pre-readers 63.546 and Slorg. Many thanks to all of them for helping this get where it is!

Now with an audio reading by TheDizzyDan!

Warning: Philosophically dark.

A lot has happened since Celestia and Luna disappeared nine hundred years ago. There are no wars, no diseases, no pain, no death. Princess Twilight, Discord, and Spike do everything to ensure that the utopia continues.

But even the most ideal paradises have ponies that wish it wasn't so.

Story inspired by Mister Saugrenu’s artwork 1000 Years in the Future.

I am Cold, swirling snow that turns ponies against each other, searing ice that freezes them solid. I am Survivor, the one the Friendfyre spell didn't catch, an exception that proves an impossible rule. I am Fear, Frustration, Anger, Hatred, every emotion my Creator has ever felt. I am her Future. I am her Past.

I am Demon, and Clover the Clever is my Master.

A three arced story that begins slowly as partially Comedy and Slice of life and rotates more towards Adventure and Dark in later chapters.

Some school fillies have to deal with school crushes. Others with bullies. Sometimes they have to deal with both. But no filly has ever had to deal with an Evil Tyrant being bound to their shadow and have the power to control their every action. This, of course, seems to be no big deal for Sweetie Belle who seems to even enjoy the stallion's company. Though the feelings aren't mutual. The small filly reminds the old king too much of a filly he used to know... Though it's strange the only place he'd seen her before are in these strange dreams of his. Recollections of a past he can't remember.

Perhaps Sweetie Belle will awake in him that version of himself before he was a Tyrant. Before he was labeled evil. A time from when he was a father. Perhaps she will help him forgive.

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

Thirty years ago — before Luna's return, before the Mane Six, before everything — Equestria stands on the brink. A harsh winter threatens starvation, discontent threatens to bubble over to full-blown rebellion, and to the south lurk dragons, hungry for vengeance and waiting for a moment of Equestrian weakness.
But Celestia knows how the game is played, and if anyone can right the ship of state, it's her. No one can dance on the edge of a blade like she can; after all, she was there when it was forged. Slowly, delicately, she charts her course —
And then everything goes wrong.

Blackacre is somewhat different fare than the usual you might find here, telling a much darker story than the sort we usually see on Saturday mornings. It won't be for everyone, but then again what is? This is a story of the long con, of the world as it is — a story both of those who reason why, and those who do and die.

Blackacre has a relatively long history. The notion took root in August 2013; it gestated for a time and took its first real steps as part of NaNo in November 2013. It took a finalized shape around April 2014, whereupon the editing started. The text here was updated in July 2014 to reflect those edits — a comprehensive revision and polishing of the text, including several new chapters and several entirely rewritten ones.
The text you see here is the final version of Blackacre; at least, I don't intend on working it over again. That's not to say I don't welcome and encourage comments, questions, or suggestions, either on the text itself or the style; I certainly spent long enough working on it the first time around, and if you enjoyed it (or didn't!) I'd be happy to talk.
Besides, there will always be room for improvement — and there will be a next time.

Blackacre has no sequel proper. At least, not yet. It does, however, have companion stories, set at different times in the same universe:
Dr. Strangehorn; or, How I Learned to Stop Worrying and Love the Elements — a one-shot set in Twilight's future, well after her rise to power.
Twelve Angry Mares — an adaptation of the classic story of a murder trial, set after Blackacre but before the show.

Reviewed one year out — and accurately so, too — by Chris.
Analytically reviewed by Cosmic Cowboy.
Rated four moustaches out of five, and later referenced, by xTSGx.

Pinkie Pie has an existential crisis while painting her room. This self-parody is dedicated to Professor Piggy, who once told me that I could write a story about Pinkie watching paint dry and weave it into an incredible psychological journey. Let's see if he was right.

This story is a sequel to Days of Wasp and Spider

Believed dead by their creators, the ponies that will become Celestia and Luna have broken their mental conditioning and escaped into the wilderness. Here they plan the revolution that will free all ponykind, knowing that it is only a matter of time before their ruse is discovered.

Back in their underground arcologies, the ponies' erstwhile masters deal with the consequences of the escape, all the while unaware that something lurking at the bottom of space-time wants them all dead.

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.
