Pain is an illusion of the senses, fear is an illusion of the mind, beyond these only death waits as silent judge over all.

Chaos Mortarion
We are all tyrants. Do not fool yourself. We were bred for nothing else.

Forget no insult, my sons, as I have never forgotten those of my father, of the Emperor, nor those of Horus. Forgive no slight or grievance. Hold your bitterness deep within, and there let it fester. Let it roil and squirm and churn, until you are filled with bile so poisonous that all you touch falls to ruin. Thus shall you serve Nurgle best. Thus shall you spread his virulent gifts across the false Imperium, and watch its final rotting.


Mortarion, also known as the Death Lord or the Prince of Decay after he turned to Chaos, was one of the original twenty Imperial Primarchs created by the Emperor of Mankind. He was given command of the Death Guard Space Marine Legion on the arrival of the Emperor to his homeworld of Barbarus, but he turned to the Forces of Chaos during the Horus Heresy. At present, Mortarion is the greatest Daemon Prince of Nurgle and the Daemon Primarch of the Death Guard Chaos Space Marines.

Standard Equipment:

  • Silence: A massive, two-handed battle scythe which Mortarion still carries into battle. The blade alone is as long as most humans are tall. Its exact origins are unknown. Some believe it to be xenos in origin, while others believe it was once carried by Mortarion's adopted father, the former necromancer overlord of planet Barbarus.
  • The Lantern: An energy blaster far more powerful than a plasma pistol which Mortarion uses as a sidearm. Once fired, a destructive beam of energy can burn through multiple enemies on its way to its true target. Just like Silence, it is of unknown origin.
  • The Barbaran Plate: Designed by Mortarion himself, this armour provides insane protection while also accounting for the wearer's environmental needs. The armour synthesizes trace amounts of the poisonous vapours found in Barbarus' atmosphere, combining them with the air the Primarch breathes.
  • Phosphex Bombs: Mortarion carries numerous, compact bombs which utilize the rare and highly corrosive material known as Phosphex. When the bombs explode, the Phosphex reacts with the air, becoming a seething green mist which is attracted to even the slightest movement. Upon contact, the substance will burn through metal and relentlessly eat away at organic tissue, not being stopped by anything short of a complete vacuum.

Intelligence: A skilled leader and master tactician.

Weaknesses: Requires the poisons from his home planet in order to properly breathe | Cannot manifest his full power outside of the Warp | None notable
