What if Littlepip's sacrifice didn't save the wasteland? What if it started another war and caused a new terrible enemy to emerge from the shadows? An enemy that has plagued Equestria for more than 200 years.

In this war for survival, humanity has only two choices: resist or fall.

Equestrian ships have been sunk by what many believe to be a sea monster but Twilight doesn't think so. So she and her friends embark on an expedition to find this so-called sea monster, only to discover that it is entirely something else.

The Bravo Team and Mane 6 must forget everything they think they know about Area 51. The truth is far worse.
