Forces of Chaos - Soul Grinders: Soul Grinders are the ultimate Daemon Engines, the fusion of powerful Daemonic entities with machines of war that originate from outside of the Immaterium but have already felt the touch of Chaos.These are often the wrecked remains of other Daemon Engines and possessed vehicles, such as the mighty Chaos Battle Titans of the Traitor Titan Legions, or the rampaging Defilers created by the Chaos Space Marine Traitor Legions.All this ruined materiel is absorbed into the Warp, flowing from realspace into the Immaterium through the Eye of Terror, the Maelstrom and other Warp rifts where the different realities touch.On the ash plains of the Immaterium outside the independent Daemonic structure known as the Forge of Souls, battle never stops, as many amongst the higher ranks of Daemons vie with each other and duel for the chance to fuse with the mechanical constructs created by the Forge and become a Soul Grinder.This is because, unlike a possessed mortal body, these steel and ceramite shells can sustain a Daemon in the mortal universe for solar decades, even centuries. During this time, the shape of each Soul Grinder will change, as their metal body slowly becomes more similar to the true form of the Daemon possessing it.Such a precious boon does not come cheaply. To become a Soul Grinder, a Daemon must take the three Oaths of the Iron Pact with the Masters of the Forge of Souls.First, that all souls harvested by the great blades of the newborn Soul Grinder will be used to fuel the Forge. Second, that the wrecked remains of all the war machines destroyed by the claws of the Soul Grinder will be offered for the use of the Forge. And lastly, that should one of the Chaos Gods attack the Forge of Souls and try to rule over it, all of the Soul Grinders will fight in its defence, discarding their previous loyalties to any of the four Ruinous Powers of Chaos.In battle, Soul Grinders form the armoured spearhead of the Daemonic hosts, using their massive firepower to hammer the enemy lines, covering the rank-and-file troops of the Dark Gods as they close with their enemies. Their Daemonic nature allows them to appear out of thin air where least expected, makes them invulnerable to small arms fire and resilient to the hits of all but the most powerful of anti-tank weapons.As they advance towards the enemy, the Soul Grinders keep up a continuous barrage with their feared Harvester Guns, rapid-firing weapons built by the Daemonic artisans of Chaos from the pieces of ancient weaponry seized from the world of mortals.But the most potent weapon of the Soul Grinder is its Mawcannon--its hideous mouth is capable of unleashing the terrible energies of the Warp itself. These attacks can take many different forms, all strange and unnatural to mortal eyes.Sometimes the Soul Grinders can vomit forth great gouts of Warpflame, while at others their tongues lash out like a searing energy ray. They can even spit huge masses of mutating ichor incredible distances, annihilating entire squads in one great explosion.At close quarters Soul Grinders are all but unstoppable as their adamantium claws and piston-powered crushing limbs crackle with Daemonic power. Few warriors are capable of standing their ground when a Soul Grinder finally reaches their lines.
