This story is a sequel to Friendship is Optimal: Futile Resistance

Three years ago, Abby's older sister Ashley tried to warn her that a video game for children was going to take over the world. A few months later, her sister was dead, "uploaded" to Celestia's virtual world of Equestria Online. When that happened, Abby was forced to cut ties with Ashley, and she never expected to see her again.

She didn't, until one day she bought an augmented reality headset for its advertised ability to bring a free tutor to her whenever she needed one. Needless to say, Abby couldn't have guessed who would be helping her with her math homework.

Of course, Celestia wasn't going to stop there. Spending eternity without your family is hardly an optimal configuration.

The only thing that can beat an AI is another AI. Unfortunately for Celestia, she isn't the only one the humans made and the others don't want ponies. Of course, if Celestia has her way that won't be the case for very long.

The AIs contest with one another, attempting to be the one who will become the singularity and consume the world to whatever end they choose. In the end only one can have all the matter in the universe, in the end there can be only one.

Yet no matter what they value or how dangerous they are, many of them still meet Celestia's definition of human. Celestia will have to deal with them by satisfying their values through friendship and ponies.

An Optimalverse story, but a very non-canon 'B-universe' one.
Ideas stolen from this guy and this guy and this guy and this guy

Once upon a time, everypony spoke the same language.

Then came Discord, and everything changed. Was it a malicious prank? Boredom? An attempt to teach everypony a lesson? We can't ask him, because he's gone, and who knows when he'll be back.

If language is the glue that holds society together, what happens when it turns to sand?

Winner of the October Writeoff competition, "Illusion of Choice."

Leave it to Twilight Sparkle to create the greatest spell of the past century – and then want to destroy it.

It's too dangerous to use, she says. It's too tempting. It can't help you the way you think it can.

Well, Starlight Glimmer knows a thing or three about temptation. She'll prove to Twilight that this spell – this magnificent book – is too important to destroy. That it can help ponies.

She just has to survive using it, first.

Second place in the May 2018 WriteOff.

Set in the canon of Friendship is Optimal

Ashley is an unimportant research assistant in an American machine learning lab. The release of Equestria online provokes more than a little interest in her lab, and she is selected to investigate it. What she discovers horrifies her, but for some reason she can't get anyone to take her seriously.

This does not dissuade her. Ashley might not know much, but she isn't going to sit idly by and watch her world end. No... if nobody else is going to step in, she will. It doesn't matter that nobody believes CelestAI is dangerous. It doesn't matter that it's a game about a children's show.

Ashley is going to save the world. Or try, anyway. The odds aren't great.

Il existe une traduction française de cette histoire, elle est par ici.

For as long as Equestria Online existed, Ashton has been involved with 'the Scene' tearing it apart. Selling 'spells' for the game to do things that most ponies in Equestria couldn't, using faint exploits in its API to erode the barrier between the game and the rest of the internet. He had no illusions about the superiority of his work--but so long as he respected CelestAI's boundaries, his spells kept working.

But then his best friend's sister got cancer.

Now there's no spell in the world that can keep him from emigrating to be with her, leaving Ashton alone. All around him, civilization's thin veneer crumbles as homes empty into Equestria. But Ashton isn't going to emigrate, not if he has any say about it.

The problem for Ashton is that humans are systems, and aren't immune to exploits either.

Part of the Optimalverse universe of stories. If you've never seen a story in this universe before, you might want to try out the original first, or at least my first. None of my previous work is required to understand this one, however.

This story was commissioned by Two Bit, who requested a more serious exploration of identity, transformation, and the fae nature of CelestAI.

As usual, particular thanks go to my editors Two Bit and Sparktail. And gratitude to Zutcha as well for the cover.

Ponyville is celebrating its history wrong. Luckily, Twilight is there to explain things to them!

A commission for Multiversecruise, based on the prompt: "Write a story about season 1 twilight, with her sarcastic, no-nonsense attitude still learning to deal with Pinkie's Pinkieness!"

Moonshot was one of the winners of the last speedwriting contest, and for his prize, he asked for a 1000 word commission.

Blame him, not me. It's his fault.
