Formerly "Unconventional Tactics."

Equestria has enjoyed a millennium of peace and prosperity, but let its power wane. Now the peace has been broken, and it lacks the power to regain it. The Elements of Harmony have proven useless, and the Royal Guard can barely stem the tide. As Equestria's enemies conspire against it and the ponies' situation grows desperate, they must return it in kind and get their hooves dirty. And a certain group of technocratic cultists displaced from their own world are just the ones to show the ponies that there can only be peace through power.
