Death Guard

Primarch: Mortarion

Homeworld: Barbarus · Segmentum Tempestus

The XIV Legion, formerly the Dusk Raiders — stubborn warriors of attrition, whose pride in their resistance to poisons and disease grew out of toxic Barbarus. Their primarch Mortarion, “the Death Lord”, nursed a grudge against the Emperor, who had stolen his victory, and saw in Horus a worthy master. On the way to Terra the Legion’s fleet became stranded in the warp, where Nurgle’s Destroyer plague turned it into the first Plague Marines. At the Siege of Terra Mortarion clashed with Jaghatai Khan, who beheaded him and banished him into the warp; later he became a daemon prince of Nurgle.

Side in the Heresy: traitors Betrayed early: Mortarion nursed a grudge against the Emperor, who had killed his foster father and lord and robbed him of a hard-won victory. He revealed his treachery in the Isstvan III Atrocity (005.M31), sending to their deaths the loyalist third of the Legion (the 2nd, 5th and 7th Great Companies).

Fate

On the way to Terra First Captain Typhon led the fleet into the warp; Nurgle’s Destroyer plague engulfed the Legion, turning it into the first Plague Marines, and Typhon into Typhus. Mortarion broke and swore himself to Nurgle, becoming a daemon prince. After the Heresy, when Barbarus died, the Legion moved to the Eye of Terror.

Speciality

Endurance and attritional warfare: indestructible foot infantry with bolters, pride in resilience against poisons, diseases and chemical/biological weapons. Siegecraft as well.

Tactics

A relentless advance on foot under bolter fire, immunity to poison; phosphex and chemical shells. Mortarion’s mute bodyguards — the Deathshroud with their manreapers, and the Grave Wardens Terminators.
