Death Guard
The fourteenth legion of the first founding, the Death Guard are a chapter of foot slogging infantry specialising in relentless, direct assault tactics as opposed to mechanised squads. When they rebelled against the Imperium during the Horus Heresy, what remained of the chapter was attacked by the Destroyer Hive, a plague that laid eggs in the sores of the Marines, who in turn called to Nurgle, the Chaos God of mortality and disease, for salvation. Now the Death Guard fight as the bloated and grotesque Plague Marines of Nurgle.
