Slud

Slud is an Imperial Feudal World and Mining World run by the Imperium through slave-rulers who received pay for the rare metals from the planet. The Imperium believes that it is best for the natives to not know too much about the wider Imperium and so limits the exposure of advanced technology.

At some point, the slave-ruler was Dartsma Ret. He chose to defy Imperial rule by dictating a set of price rises, which led to the Imperium choosing to replace him with a more cooperative puppet. To do this, the Imperium sent a squad of Space Marines with orders to stay incognito, leading them to only use medieval-type armour and equipment.
