I'm sure you've heard all about it by now. Rainbows and sunshine. Unhappy humans turning into happy ponies. Dancing and singing together in harmony, now and forever.

All of those stories you've heard, exaggerated. All those statistics and graphs, faked. Propaganda. Delusions.

They didn't tell the real story, what it was actually like. So, I've decided to write this book to record some of the truths that have been... glossed over.

My name is Matthew Roberts, and I'm the Mayor of New Hope. While my covering may have changed, I am still human.
This is the untold story of the Conversion. The one they never wanted to acknowledge.

Tiberium. The infamous green crystal that destroys entire worlds in its wake of global proliferation. It has been a little over a century since the Tiberium threat was first wiped out on Earth, and with it, the primary vestiges of the Brotherhood of Nod. When the GDI advanced humanity to the stars, they found that Earth had not been the only target of the alien Scrin: dozens of other worlds had already been claimed by Tiberium, and the Scrin returned in full force, attacking human colonies across space, stopping human expansion. To fight back, the GDI undergoes a reformation to become the Interstellar Defense Intiative (ISDI) and enacts the Hallman Directive, designed to stop Tiberium spread wherever it may be; such a protocol brings the reincarnated ITC Methuselah to a planet being ravaged by the green crystal, and the forces under Commander Martin Alexandra deploy to stop the threat.

This story is undergoing a massive rewrite. Expect everything to change soon.

A Russian MVD Spetsnaz team is sent smashing into the ground after the Mil Mi-24 they were in was knocked out of the air. A short time later, the crew and passengers wake up to find themselves in the wreck of the helicopter - but nowhere near Moscow.

As they desperately attempt to find out where they are, they will discover that they are not alone: Other humans have also found themselves in similar situations. However, these disorganized forces may soon be fighting for their survival, against an enemy that they could never have planned for...

The original version of the story, as published 2013-2015, can be found here for those that want to read it as it was. Editing on the original story was done by The Rainbow Brony, and I am thankful for the time that he put into the story to make it better than it would have been otherwise.

On a winter morning in Ponyville, Rainbow Dash throws a snowball at Applejack.

Things escalate quickly.
