Kurt Mannfeld was an arch lector of the Cult of Sigmar of the Imperial city-state of Nuln whose army battled the Chaos Marauders of Archaon and Beorg Bearstruck.[1a][2a]
In 2510 IC Mannfeld led an army allied with Kislevites and Dwarfs to the Chaos Wastes to rid the mortal world of the Chaos Lord Archaon. His army is utterly crushed at the Battle of the Monoliths.[3a]
Archaon utterly defeated the army of the warrior-priest and persuaded the shattered man to acknowledge the rule of Chaos, claiming victory over Sigmar, the patron god of the Empire.[2a]
