===They Came From Underneath===

Despite the threat of the Orks, there were threats to the defense of Vigilus much closer to home. Centuries before, a [[Genestealer Cult]] derived from the '''Pauper Princes''' had managed to get a single Purestrain Genestealer onto the world. It grew into the [[Genestealer Patriarch]] called the '''Grandsire Wurm''', and its cult refused to let its years of preparation go to waste due to the unexpected greenskin arrivals. Uprisings that were supposed to be triggered decades down the road were forced to do so prematurely, and soon every Hivesprawl was in chaos due to the simultaneous insurrections. Imperial defenders fell to synchronized ambushes across the planet as the Cult consolidated its hold on the Hives.

The response to the Genestealer Cult-led revolt was slow, as the Imperial Government initially thought it was the work of criminals and malcontents and instead focused on shoring up its defenses. These uprisings, plus the constant ork raids, essentially forced the industry on the planet to grind to a halt. Things were, to put it mildly, looking grim.
