Gudrun is ruled by a feudal system of noble patronage including such powerful noble houses as the Glaws, the Pariti and the Froigre.
Gudrun's influence originally extended even beyond its own star system into neighboring worlds. It is also the recruiting ground for the Gudrunite Rifles Regiments of the Imperial Guard. The raising of a new regiment for the Guard is always a cause for a planet-wide celebration. Once the capital of the Helican Sector, in 241.M41 one of the preeminent noble houses on Gudrun -- House Glaw -- was found to be pervaded by a Chaos Cult.
After a successful Imperial Crusade launched against the Heretics of the world by Battlefleet Scarus and the destruction of House Glaw, Gudrun lost the honour of being the capital world of the sub-sector to Thracian Prime due to the damage suffered to its reputation for loyalty.
Before its corruption, Gudrun was a relatively idyllic world with stately manors controlling vast estates of rolling green hills studded with small villages. Its culture was not dissimilar to ancient ideas of "Merry Olde England." For a time it was the home and headquarters of the Inquisitor Gregor Eisenhorn.
