The Death Guard are one of the original Traitor Legions of Chaos Space Marines, infamous for their unwavering endurance, grotesque resilience, and fanatical devotion to Nurgle, the Chaos God of decay, disease, and entropy. Once noble warriors under the command of their primarch Mortarion, the Death Guard were transformed during the Horus Heresy into plague-ridden monstrosities when Mortarion, desperate to save his Legion from a warp-borne contagion, unwittingly swore allegiance to Nurgle. Reforged in the image of rot and despair, the Death Guard no longer feel pain, fear, or weakness — their bodies bloated with corrupted organs, their armor fused to diseased flesh, and their spirits shackled to the will of their pestilent god. Where they march, sickness spreads, civilizations rot, and the soil itself turns to mulch beneath their feet. Slow but relentless, they embody the inevitability of death and the futility of resistance. To face the Death Guard is not just to fight warriors — it is to wage war against plague incarnate.
