In an island bunker hundreds of miles from Hippogriffia's mainland, the nation's finest scientists and high-ranking party members anxiously await the countdown for the world's first thermonuclear bomb. In-attendance are Posada, the eccentric Communist revolutionary and Head of State of Hippogriffia. Terrafin, Posada's trusted scientist and friend, as well as project lead and architect of Operation Sunset. And finally, Posada's main advisor and very close friend, former Princess Skystar.

Today is the culmination of Posada's dreams and visions. The ability to harness nuclear fusion as a weapon, and perhaps eventually, harness it as a power source for long expeditions to the stars. However taming the power of the stars is far from an easy task, and leads to something no one could have seen coming.

Warnings: Mentions of suicide, depictions of injuries and blood, and implicit sexual content mentioned once.

Playing through Posada's full path in Equestra at War is recommended (because it's amazing) but not at all required. It just gives you more context on the universe and characters.
