Trixie is arrested for holding Ponyville hostage under a giant dome. Instead of jail, she chooses to serve her sentence as a member of the Lunar Guard.

It goes about as well as expected.

With only a broken wagon, seventeen bits, and a shattered reputation to her name it seemed that the world could not grind The Great and Powerful Trixie down any further. When an old friend offered Trixie the opportunity to start again, with a heavy bag of bits to help her back on her hooves, she grudgingly accepted. All that was required was a little magical assistance; no schemes, no cursed amulets, no risk of getting banished to the moon.

They never told her the ritual was to summon the Nightmare back to Equestria. Now, as the Nightmare’s new host, all that stands between Equestria and eternal darkness is the determination of Trixie Lulamoon, a mare who already lost everything for the sake of power. In her quest to maybe save the world, and certainly save herself, Trixie will explore the depth to which power can corrupt and the lengths ponies will go to possess it. It’s that, or break on life’s wheel.

An A.I. awakens aboard the HKS Dancer, a desolate and quiet ship. The crew of which is nowhere to be found. And in the wake of all of this the A.I. discovers something.... something peculiar.

A super cool 3d model that is relevant to this story.

"...The test ends when you open that door."

But just what is the purpose of this test? And how can somepony pass it?

The war ended. They were beaten back, their mothership destroyed, their command structure in ruins. Lost ships and soldiers continued in vain, but thanks to XCOM, humanity won, and the world was saved. The Volunteer saw to that - everything changed because of one man.

And then suddenly, everything changed again. Only this time, it's not a man's doing - it's a mare's.

What if pony princesses were actually highly social carnivores?

What if a National Geographic team began following them around to film a documentary?

What if nopony saw anything unusual about this?

A metaphor about growing up. Or possibly a metaphor about living in a surveillance society. Or maybe just a very, very weird idea that needed to become a story.

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

Twilight went to take her entrance exam for Celestia's school for gifted unicorns, and she had a surge. But when the Princess of the sun shows up, all Twilight can think of is getting away. The look of concern for those she transformed was too much. In a flash of light, the little filly disappears with one thought on her mind.

"I've disappointed them all."

Rainbow Dash usually had her head in the clouds, but she always thought she knew up from down. When an incredible revelation sends her life into a tailspin, she finds herself at the mercy of emotions she never thought she had, faced with hard questions and impossible choices.

Life is full of changes, but none of them are quite as disturbing as having a horn pop out of your skull…

Original Lauren Faust canon; non-alicorn Twilight, non-alicorn Cadance, no ascension. Diverges from the cartoon after season 3, with nods to later continuity wherever possible. Contains mature themes.
