An ancient evil has awakened. No, really, it has. From the depths of time, a black, noxious threat has risen up after millennia of imprisonment. It washes like oil over Equestria, swallowing up towns and uncovering terrible secrets long buried. Twilight Sparkle, Applejack, Rainbow Dash, Pinkie Pie, Fluttershy and Rarity are prepared to combat this great darkness. However, to do so, they must uncover the truths about the Elements of Harmony, and the truths about the ancient forerunners of Equestrian culture. What they find will challenge their conceptions of their own places in history and ponydom's place in the world. The six Bearers of the Elements must draw upon their friendship and the strength of their hearts to stand firm against the darkness. If they fail, it will mean the end of everything.

Awake and alone, Applejack will find a way to survive.

And here's a TV Tropes page, if you're into that kind of thing.

It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.
