Mortarian Primarch Siege of Terra Books Horus Heresy

Mortarion, the Daemon Primarch of the Death Guard, is one of the most fearsome figures in the Warhammer 40,000 universe. Originally the Primarch of the XIV Legion, Mortarion was known for his grim demeanor and relentless pursuit of victory through resilience and endurance. His home world of Barbarus, a toxic and deathly place, shaped his character and his legion, making them experts in chemical warfare and endurance against harsh conditions. During the Horus Heresy, Mortarion’s loyalty shifted to Chaos, swayed by the promises of power and the corruption of Nurgle, the Chaos God of decay and disease.

As a Daemon Primarch, Mortarion’s transformation was both horrifying and magnificent. He became a towering, plague-ridden entity, embodying the very essence of Nurgle’s gifts. His once noble visage is now twisted and decayed, covered in the filth and corruption of countless diseases. Wielding his massive scythe, Silence, and accompanied by a cloud of noxious fumes and daemonic followers, Mortarion spreads pestilence and despair wherever he goes. His presence on the battlefield is both terrifying and devastating, as he commands legions of Plague Marines and daemons with unyielding determination. Mortarion’s ascension to daemonhood solidified his place as a central figure in the Chaos pantheon, eternally bound to the service of Nurgle and the spread of his vile plagues across the galaxy.
