Forged in the fires of conflict, the Iron Kingdoms is a fantastic realm where the combined power of magic and technology thunders across a landscape shaped by war. Dominating the field of battle are rare individuals who have mastered both arcane and martial combat and who boldly lead mighty armies in the ongoing struggle to claim victory over these ancient lands.

An untrustworthy ally is more dangerous than a known enemy.

Lord General Coleman Stryker is one of the greatest heroes of the Iron Kingdoms. As a warcaster, Stryker leads the armies of Cygnar and commands the power of the mighty steam-powered automatons known as warjacks.

Chosen by his king to liberate the conquered lands of Llael from Cygnar's long-standing enemy, the Empire of Khador, Stryker finds himself forced to work with one of his most bitter enemies - the exiled mercenary Asheth Magnus, a man to whom Cygnar's king owes his life. Unchecked, Magnus could easily betray Stryker, undermine the mission, or even bring Cygnar to its knees. But to claim victory for his king, Stryker will have to find a way to put his faith in a man he can't trust.

As the war against Khador and its own fierce commanders looms, Stryker's success or failure will become the flash point that determines the fate of all the Iron Kingdoms.
