The Western Marches of the Principality of Koth are burning. Internal rebel factions have declared against the capital, and across the border the Kingdom of Krovan sees in this chaos an opportunity to settle grudges that have never been properly addressed. The Principality's response is to deploy Sergeant Heimer—experienced, difficult to be around, and rarely sober—with a ragtag collection of soldiers and the authority to handle things however he judges appropriate. Empires in Ruins blends tower defense with real-time strategy and tells its story entirely through Heimer's jaundiced, frequently profane perspective on a world that has repeatedly disappointed him.
