General Damon orders the deployment of Gallian militia to Fouzen out of his irritation for their growing popularity with the Gallian people and their success against the Imperials. While some of the Gallian Militia attack Fouzen by launching a diversionary tank assault, Welkin and Faldio lead their units in civilian clothes in order to covertly make contact with a Darcsen resistance group led by Zaka. After arriving in Fouzen, Rosie tells Zaka of her clear dislike to the Darcsen people because of their history. Despite this, Zaka tells Rosie that he understands her anger as he and that his fellow Darcsens had become used to anti-Darcsen discrimination a long time ago. Welkin, Faldio and Zaka proceed to make preparations to destroy General Gregor's armored train known as the "Equus", while simultaneously attacking the Imperial military Headquarters and Darcsen concentration camps in Fouzen.
When Imperial forces attack the small border town of Bruhl, Welkin Gunther, son of late General Belgen Gunther, is forced to fight for his life alongside Town Watch captain Alicia Melchiott. Along with Welkin's adopted sister Isara, the three escape to Gallia's capitol and subsequently join the country's militia forces. As members of the newly-formed Squad 7, they must work to repel the invading Imperial forces and discover the true purpose of the invasion itself.
