Laudus Skythunder is a Knight-Heraldor of the Hammers of Sigmar and is part of the Command Chamber of the Hammerhands.
He remembers little of his mortal life save for the screams of his loved ones as they were swept away by the raging waters surging through the broken Quartz Dam of Lennaris. 
The war-caller Laudus stands firm in teh thick of battle, his horn sounding out to bolster the resolve of the other Hammerhands, having done so on the slopes of Mount Kronos then into the Hell Breach created by Ignax and into the Bloodcombe fortress.
