From Huaxi Dark Source (Hainan) Tech. Krieg was the site of a rebellion against the Imperium of Man over 1,500 standard years ago and was bombarded with nuclear weapons followed by five hundred Terran years of grinding warfare to purge the heretical rebels. Krieg was reduced to a scorched, radioactive husk of a world composed of dust and mud whose surviving people were forced to retreat into underground hive cities to survive the toxic planetary environment. The Death Korps of Krieg is a siege specialist Militarum Regimento of the Astra Militarum and the regiments raised on Krieg seek to repent for their former treachery against the Emperor by displaying a disturbing disregard for their own lives in combat.
