Changes

They were among the [[Death Guard]]'s forces that took part in the [[War for the Tri-forge Cluster]]. There, the [[Vectorium]] joined the invasion of [[Thrios]] and seized a factorum, that produced variants of [[Hellhound]]s, early in the invasion. Under the leadership of their [[Chaos Lord]], [[Ferund Irnwelt]], the Rustwalkers's [[Sorcerer]]s and [[Dark Mechanicum]] allies corrupted the factorum's ancient machinery. This resulted in its Hellhounds possessing ferociously warped [[Machine Spirits]] and the Death Guard had their most fanatical followers crew the tanks. Scores were created with each passing day and then sent against the Imperium's forces defending Thrios. Weeks of this went by, until an Imperial strike force was sent to attack the factorum and stop any more of the corrupted Hellhounds' from being created. Composed of lances of [[House Adamant]] and [[House Althalos|Althalos]]' s [[Knight]]s, as well as battalions of [[Thrios Furnaceguard]] infantry, the attack initially went well. The Imperials were able to push their way through the [[Cult]]'s defending the factorum and entered its depths. However this had been allowed by Lord Irnwelt, who soon sprung an ambush upon the invaders. In the battle that followed, numerous corrupted Hellhounds, Cultists, and the Rustwalkers themselves, ensured that the Imperial strike force was completely destroyed.{{Fn|1}}
