Why the Death Guard Embrace Decay | Warhammer 40K Lore

The Death Guard were once among the most resilient and loyal Space Marine Legions in the Imperium. Led by their Primarch Mortarion, they fought across the galaxy during the Great Crusade as relentless warriors capable of enduring unimaginable hardship. But everything changed during the Horus Heresy. Betrayed by fate and consumed by the horrors of the Warp, the Death Guard became the favored servants of Nurgle, the Chaos God of disease, decay, and endurance. Today they spread plague, corruption, and despair across the galaxy while remaining almost impossible to destroy.
