Viewer discretion advised. Needless to say, Keep Calm and Flutter On never happened.

A diamond dog Warlord, his earth pony general, and a talented gryphon mercenary conspire to bring back Equestria's worst nightmare. The dangerous draconequus plans to reward the three, and knows just the way to do it while making sure the Element Bearers are... preoccupied.

Namely a little game, a game that'll lead the mares of Ponyville into a danger that they're not prepared for. Can Twilight and her friends figure out a way out of this, and even if they do will it be too late for the rest of Equestria?

Inspired by one part RP, one part (used wiith permission) SkyDreamer's amazing story Game of Estrus and one part Fall of Equestria.
