Overlord Wars
The Overlord Wars was a campaign launched by the Primarch Mortarion, that exterminated the cruel Overlord Xenos species that ruled his Homeworld Barbarus[1a]. With his first comrade Calas Typhon, Mortarion gathered those from Barbarus' fearful Human populace that were willing to follow him and turned them into an army that hunted down the Overlords; the elite of which, were known as the Death Guard.[1b]
