There are 100 billion stars in the Milky Way, and humanity is determined to explore every one. We send probes, probes with the blueprints to reproduce human explorers upon arrival. Uninhabited worlds the galaxy over can be colonized and populated, until after many years they too can join the vast throng of interstellar civilization. But if a probe is very, very lucky, it will land on a populated world instead. Equestria is one such world.

Even so, it's far from perfect for colonization, not with an environment lethal to human life. But each probe is resourceful and armed with the greatest machine intelligence mankind has devised. If placing a human mind into a newly manufactured human body won't work, it will just have to get a little more creative.

Fantastic prereading help from: Chyre, Danger Noodle, Doctor Disco, and Doggyshakespeare (who also did the Esperanto translation). Thank you all for helping to make this story more readable and more consistent for everyone.

Two years after Equestria began its slow collision with Earth's universe, an opportunity to survive the barrier has been developed by the combined efforts of humanity and ponies: conversion. With conversion serum, or potion, a human can become a pony and survive the barrier that is slowly consuming the earth. However, Princess Celestia is all too aware that there are things other than life which humans value, and would reject conversion for. That is why she has summoned Twilight Sparkle to Canterlot to begin a daunting task in order to preserve humanity even further.

Written for the TCB group's Event XIII.

Set in Guardian_Gryphon's Gammaverse

Prequel to the story The Conversion Bureau: The First Choice

Magical beings besides the Sirens have been banished to the human world.

Equestria has appeared on Earth. But instead of joy and knowledge; it has bought death, pain and destruction. Who is responsible for this? The Solar Tyrant Celestia.

She has professed kindness, tolerance and compassion. But backed up by the point of a sword, kindness becomes cruelty; tolerance becomes intolerance; and compassion becomes hate.

But there is hope. the Selenian Rebellion. Composed of beings from Equestria and Earth and led by Princess Luna, they are all united by a single cause - stopping the Solar Tyrant and restoring peace to the joined worlds.

Can this group succeed or will Earth and Humanity be trampled under the iron-shod hooves of Celestia's military?

Author's Notes: I would like to thank Restless Coyote from Space Battles for suggesting the the title to this story.

Lazy Pines is a small town in the high country of Colorado, easily overshadowed by the bigger sights to see along Colorado State 9. When influenza strikes the town hard, it is little more than a statistical blip in a typical flu season. No one thinks any more of it as the initial wave of infection passes ... until the other symptoms begin to manifest.

Meanwhile, during what should have been a routine trip to Canterlot, Twilight Sparkle stumbles upon a strange anomaly which turns into an all-consuming mystery. As she discovers the complex web of magic stubbornly maintaining this mystery's secrets, she grows worried what it could mean for herself and her family.

And as the residents of Lazy Pines struggle to understand -- or even believe -- what is happening to them, two worlds have irrevocably been set on a direct collision course.

Immortality. It's said to be the ultimate achievement. The negation of the one true hinderance to all forms of life, the binding and unifying factor that every mortal being shares. Those who are without it, wish for it. Yet those who have it... They wish it gone. For while eternal life stands as a tribute to an infinite amount of triumphs, it harbours one simple truth. Immortality isn't living forever, it's everyone you love vanishing around you.

For some this is of little concern, for they are without the bonds of friendship and affection. Why worry about the longevity of loved ones that don't exist? Others fight to keep those they care about alive, betraying all reason in the name of a struggle against the cosmic rule of entropy. Many simply retreat from sight, becoming recluse, hidden and forgotten. Yet the last archetype, they do nothing of the sort, for they have not yet exceeded their mortal lives. They are determined, free from the strife of a million year existence. These beings turn desperation into action, travesty into opportunity. Darkness, into light.

When all seems lost, all it takes is one final effort, a stand against impossible odds. And that's what guardians are best at, isn't it?

If large scale crossovers aren't really your thing then I'd advised you to read no further into this story. This is a Destiny/Halo/Mlp crossover, the lore of each universe will be changed to fit the flow of the story. Some changes may be small but many are rather large. Prior knowledge of each universe is very much recommended, although I will try my best to write it in a way that is enjoyable for everyone. As it stands this is also my first fan-fiction, so constructive criticism is not only welcome but encouraged. Any ideas regarding changes or upcoming chapters are also welcome. Thanks.

Another note, this interpretation of the Destiny universe will not take into account any of the events following on from the original game. If this causes anyone to lose interest I fully understand. Just thought I'd let you know what you're getting into.

Final note from 5 years after the original publishing of this story, I recently put this back up after a period of 2 years unpublished because I recieved requests from people wanting to read it again. I don't plan to continue this version of this story, however if in the future I find myself with more free time, I may make an attempt at rewriting it, bringing it into the modern era if you will. Until that potential day, I hope you enjoy this wild trip back to 2016.

It can be said the multiverse is a series of rivers, each one its own reality, all flowing infinitely close to each other, but never touching. When one river receives a sudden influx of energy and overflows its banks, touching another reality in the process, two species must come to terms with their sudden awareness of the other. And as the deeper ramifications of their meeting become apparent, both species must make a choice as one.

While this is a direct sequel to In Duty's Name, it is not required to read it. It is recommended, as it will help you get to know everypony better :)

This is a re-imagining of The Conversion Bureau universe as originally created by Blaze. All Canon characters are (c) Hasbro and Studio B. All Original Characters are (c) to their respective owners

The multiverse is a wild and varied place. And the lives of ponies can take many forking paths and the case of Trixie Lulamoon, those paths are very twisted and complex indeed.

In one universe, she's the Element of Magic and the personal student of Princess Luna. In another, she's been tasked with cleaning up corruption in the city of Neigh Orleans by Princess Celestia. And in both they're talented magic users.

And when an ancient magic item switches the two between their universes, they'll both have to scramble to find a way back home.

A Lunaverse/Skitchverse crossover.

Sunset Shimmer is a young mare who strives for power and doesn't care about anyone but herself.
