Twilight's power, along with that of Celestia, Luna, and Cadance, has been claimed by Tirek. Drunk on power, the demon-centaur is unleashing destruction upon Equestria, his reign of terror just beginning.

But there is hope. A crystalline chest, a gift from the Tree of Harmony, able to be opened by six keys. Keys which Twilight has now claimed the last of. All they can do is hope, hope that whatever is contained inside the chest is enough to stop Tirek.

And then something goes wrong ...

Note: This story is in no way connected with my other fanfics. It's very much a one-off in good fun.

Everything changes for Twilight Sparkle and her friends when a mysterious extraterrestrial ship crash lands in Equestria. When Twilight messes around in the ship's systems with her magic, she ends up transported to an alien world unlike anything she imagined: a box canyon in the middle of nowhere.

To get home, Twilight must enlist the help of the eccentric Red and Blue soldiers that live there... if she can get them to stop bickering first! Additionally, she finds herself being pursued by the enigmatic military agency known only as Project Freelancer. Back in Equestria, all is not well for Twilight's friends as forces involved with the crashed ship make themselves known. Reds, Blues and ponies will all have to work together to discover the mysterious connection between Equestria and Project Freelancer.

A crossover with Red vs Blue. Written with the intention for the story to be followable without having watched the series. (just don't expect to get all the references).

Now with editors! BradtheBrony and Rough_Draft.

I made a blog post explaining things. You should read it.

TvTropes Page.

The Arbiter. That is merely his title, nothing more. He has no name, no family, and no future... until now.

This Arbiter, he who was born of hate and wrath, thought no creature, let alone a mere human, could ever best him in combat. But, he was wrong. In the events of the Halo wars campaign, the Arbiter fought sergeant Forge multiple times, each time suffering a heavier, more degrading defeat. And at last, just when he thought he had the pestilent human, the gods suddenly turned their wrath upon him for his failures, and he failed against the little human, and perished on the shield world containing the forerunner fleet... or so he thought.

The gods he followed may have forsaken him on that day, but another, more fun power gave him another chance, to begin again, in a new world of its choice. However, that power failed to specify the Arbiter's new purpose, and dumped the belligerent sangheilli into a world that tests his very patience every moment of every day. Will he finally discover the source of true peace here, in this colorful, pony-filled world, or will he burn the fetid, cutesy, scum-sucking, human-loving planet to its bedrock!?

...Probably the latter.
