The year is 1977. The Soviet-backed New Lunar Republic is at war with the United States, led by Comrade General Secretary Luna - or is it, indeed, Nightmare Moon?

The war rages on, from the Everfree of Washington to the Rocky Mountains to the Texas Corridor, seen through the eyes of an ensemble cast, while the ponies in and around Canterlot play dangerous games. The arrival of certain human prisoners of war, captured in border skirmishes, makes for new, unpredictable, and potentially powerful pawns, even if one is a failed conscientious objector and the other has a head injury. Comrade Madam Mayor of Ponyville and Pony's Commissar Foggy Night just want to help Sweet Apple Acres meet its production quotas, but Commissar Blueblood dreams of being Prince Blueblood once more, while the exiled Princess Celestia has big plans indeed - and not even her most faithful revolutionary, Twilight Sparkle, can pull them off all by herself.

Trigger warning: commies, slavery (specifically, forced labor substantially compliant with the provisions of the Geneva Convention and bearing no sexual character whatsoever)
