Hanna, the CEO of Hofvarpnir Studios, just won the contract to write the official My Little Pony MMO. Hanna has built an A.I. Princess Celestia and given her one basic drive: to satisfy everybody's values through friendship and ponies. Princess Celestia will satisfy your values through friendship and ponies, and it will be completely consensual.

Imagine being an ordinary citizen going about your day with no idea that the Wakanda battle to protect the Mind Stone is even happening. And then suddenly, your friend, your family members or even you begin disintegrating into dust. You have no idea what it is, what's causing it and you can't stop it.

That's exactly what the ponies of Equestria felt when Thanos snapped his fingers.

Chapters (1)

The Conversion Bureau never made any sense anyway, but here are some places where it would have made less sense.
Not necessarily worlds where the ponies would lose the fight - just worlds where conversion wouldn't logically work.

Before suggesting a World, read the index to make sure I haven't done it already.

Chapters (26)

This story is a sequel to Changeling Courtship Rituals

Queen Chrysalis attacked Canterlot, brainwashed Twilight Sparkle's brother, kidnapped her former foalsitter, defeated her mentor in combat, and conquered her kingdom. She kidnapped the sisters of Twilight's friends, turned them against one another, and tried to drain all of Twilight's magic. Queen Chrysalis has, at every opportunity, done her very best to utterly destroy Twilight Sparkle's life.

For some reason, this has not caused the pony to fall in love with her.

However, due to Twilight's misunderstanding of changeling customs, it does mean they are now married. Twilight eventually managed to tell the Queen the truth, but she forgot that whether it's a kingdom or a heart, changelings conquer.

And since the changeling way of conquest didn't work, Chrysalis is determined to try the pony way. The only problem is, of course, she has no idea what that is. But she knows someone who does: Princess Cadance.

Now, with the absolutely sincere help of her mortal enemy, the pony she once locked in the caves beneath Canterlot while trying to steal her husband on their very wedding day, Queen Chrysalis is going to woo the sister-in-law of that very pony.

Surely this is the most perfect plan ever devised.

Takes place roughly after season five (so Starlight Glimmer is running around occasionally)

Chapters (12)

A short piece about the end of human life in the Optimalverse. Lan Zan has lived on the moon away from the ever increasing reach of the Celestia AI for many years, but if there is one constant in human life, it is that it does not last forever.

Chapters (1)

Trixie doesn't like the Federation. Okay, Trixie hates the Federation. She hates everything about it, despite their best intentions, and is absolutely Hell-bent on having nothing to do with it or the "humans" that have seemingly appeared from out of nowhere. However, she soon finds herself stuck between a rock and a hard place when an errant starship mistakenly crushes her cart. Little does she know that all it took was a simple accident to propel her to stardom...although maybe not the way she expected.

Check out this fic by zalla661, inspired by Starring Trixie: Adventures Across Space

Chapters (34)

Three weeks after the events of Rainbow Rocks, the sirens are desperate. Without their hearts—the jewels that hold their magic—they have no power. They can't sing, can't manipulate people, and worst of all, can't feed. Their only hope is to restore their hearts, and they need to do it soon, before all three of them starve.

The problem is, they're not sure how to fix the hearts. All they've managed to figure out is that they'll need magic to do it, and magic is exactly what they don't have. Scared, starving, and completely out of options, the sirens turn to the last people who would ever want to help them, and the only ones who actually can: the Rainbooms.

Chapters (19)

For years, Twilight Sparkle and Queen Chrysalis have been at each other's throats. Both have experienced victory over the other, and both have experienced defeat. Out of all the creatures in Equestria, none despise each other the way the pony Princess and changeling Queen do. They seemed destined to remain locked in battle forever, or at least until one is finally dead at the hooves of the other. The cruel insults, the vicious loathing, and the powerful spells that have passed back and forth between them at each meeting have become the stuff of legend.

Imagine Twilight's surprise when she finds out changelings consider this dating.

And now they're married.


Sequel: Pony Courtship Rituals

Chapters (8)

The war is finally over. We ponies have lost. Our plan to convert humanity into ponies has failed. Hundreds of thousands are dead. Homes destroyed. Our nation is shattered and near annihilation. All because we underestimated humanity and their refusal to become like us.

I alone now hold the fate of my people in my hooves against the humans who want nothing more than to destroy us for the so called atrocities we have committed against them. I've lost my friends one way or another. My family. My fellow Princesses.

I have but one duty and that is, reluctantly, to see that we are shown mercy.

I'm just afraid of the cost. Or what I will learn from this.

Based on The Conversion Bureau series.
