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.

A knight of Cygnar follows a strict moral code. His integrity is beyond reproach. He holds himself to the highest standards whether dealing with friend or foe. And he values honor above all. The year is 606 AR, and Cygnar has been sorely pressed by its enemies both at home and abroad. In Caspia, the conflict with the Protectorate is about to erupt into full war with the looming invasion of Sul. The Cygnaran military is desperate for soldiers with the skill, strength, and bravery to take up the devastating galvanic weaponry of the new Storm Division.

Allister Caine has always been an enigma and an outsider among the warcasters of Cygnar, but few are privy to his true motivations or his complicated past.… Born into poverty, Allister Caine did what he must to survive, and the choices he made have followed him like a vengeful specter throughout his life. Now, just months after the Lion’s Coup and his full commission as a warcaster, he has been secretly assigned by Scout General Rebald to investigate plots against King Leto in lands just north of the Bloodsmeath Marsh.

Sinister forces lurk in the corners of the Iron Kingdoms - restless souls, mischievous and cunning creatures, darker beings that bargain for mortal souls. Most pass unmarked, shunned, or avoided, but there is one group willing to seek out and study what others fear. In abandoned halls and forgotten ruins, the investigators from the Strangelight Workshop illuminate the darkness, armed with wisdom, curiosity, and specialized tools.

The Iron Kingdoms is a land dominated by mighty warcasters, arcanists who command the terrifying war machines called warjacks.

Called to Battle is a collection of stories focused on the Iron Kingdoms’ unsung heroes, its skilled mercenaries, and even the horrifying villains who haunt its darker reaches.
