|Class:||Death World, former Hive World|
Krieg was previously a prosperous Hive World of billions located in Segmentum Tempestus, specialising in manufacture and trade and led by a council of Autocrats. However, as time passed, the debauched and decadent Autocrats began to become paranoid that an outside threat would take their power away from them, and thus began to increasingly fortify the world from outside threats. Eventually, the Autocrats also began to resent the influence of the Administratum on a planet that they considered to be their own.
Finally, in 433.M40, the High Autocrat declared himself independent from the Imperium and renounced the Emperor as his divine master. Civil war broke out on Krieg and much of the planet quickly fell to the rebels except for Hive Ferrograd, which was under the command of the now-infamous Colonel Jurten of the Krieg 83rd Imperial Guard regiment. Under strict orders to not let Krieg fall, but in the knowledge that no fleet on the scale needed to relieve them was available, Jurten decided that Krieg would either belong to the Emperor or to no one. On the day of the Feast of the Emperor's Ascension, Jurten unleashed a counter-attack of atomic cleansing in what became known as "the Purging." For days Krieg was engulfed in a sea of nuclear fire, resulting in a total collapse of its ecosystem and subsequent nuclear winter, but the civil war dragged on. The survivors from the Purging would fight on but were forced to exist in underground bunkers or deep in the radioactive chem-wastes, as their descendants do to this day. From the self-annihilation of their homeworld, loyalist troops slowly retook their world inch by inch over the course of 500 years until finally returning to Imperial rule in 949.M40. It would be from this cataclysmic event that the Death Korps of Krieg were born.
As a result of its cataclysmic civil war, Krieg itself remains a barren and death world, wracked by radiation storms and uninhabitable toxicity levels. Much of the population growth on Krieg is undertaken by the Vitae Womb system.
Krieg is German for "war."
