The first Nightmare Night with Princess Luna was fantastic. Big Macintosh had finished his cart rides, and was ready to mingle with the rest of Ponyville. When Cheerilee comes rushing up with Scootaloo and Sweetie Belle in tow, they learn Applebloom went missing from Pinkie's little herd. A search begins, and a creeping dread comes over Big Mac, as he can't help but notice a strange scent in the air, as they draw closer to the Everfree Forest...

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.
