Thostos Bladestorm, Lord-Celestant of the Celestial Vindicators, has not been the same since his Reforging. Once a noble warrior whose zeal was tempered by compassion, now he is cold and unforgiving, hungry only for battle. But there is little time for his fellow Stormcast Eternals to come to terms with his transformation, as the Bladestorm and Argellonites Warrior Chambers are sent by Sigmar to the Realm of Beasts to capture a vital realmgate. During their quest they face myriad threats, from traitorous tribesmen to the vast hordes of Drekka Breakbones' Ironjawz. All wonder how Thostos will react to these perils - will they see once again that great and righteous leader, or is he lost to them forever?
