The Berserkers of Arnkorn is a Chaos warband that is supported by both Traitor Militia and Chaos Space Marine forces. The warband was formed by Darkon Secoth, a former member of the Imperial Sentinels chapter, who turned renegade during the 1st Battle for Purgatory. The Berserkers are well known for their battle-crazed troopers who are known to launch devastating charges into close combat with their enemies. Surely the gifts of Khorne are bestowed upon those who embrace the heat of battle, and that is exactly what the Berserkers of Arnkorn do.
