Harl Greyweaver, Iron Priest of the Space Wolves Chapter and Forge Master of the Deathwatch's Watch Fortress Erioch

Harl Greyweaver is an Iron Priest of the Space Wolves Space Marine Chapter who has been seconded to the elite xenos-hunting Deathwatch -- the Chamber Militant of the Ordo Xenos. He has been the Forge Master of Watch Station Erioch since his predecessor answered a summons to serve the Achilus Crusade a decade ago. While the influence of Greyweaver’s time in the unorthodox halls of the Deathwatch shows in his Servo-Harness and other small deviations from the traditions of the Iron Priests of Fenris' Isles of Iron, he is not nearly as compliant with the teachings of Mars as many of the Techmarines who serve under him wish. The Iron Priest has adorned most of the fortress’ major workshops with icons of the Iron Wolf, and rivers of molten metal flow through his domain deep in the heart of Erioch. He is notoriously intolerant of other Chapter’s brands of tech-craft, but his efficacy in conjuring the tools of war is so great that no one has yet been able to oust him. His fervent hatred of alien technology puts him at frequent odds with the Crucible Resolviate and Inquisitor Quist. Every piece of xenotech adopted into the Deathwatch arsenal since his arrival has been done so only grudgingly.


  • Artificer Power Armour
  • Servo-Harness - Like a Servo-arm, a full Servo-Harness integrates with the Techmarine’s Power Armour and is controlled through the same cybernetic spinal interface that makes him one with his armour. Radiating from a boosted fusion backpack capable of powering them all, this cluster of auxiliary limbs aid in battlefield repairs as well as combat. The composition of each Servo-Harness is unique, customised with the tools most preferred by its previous owners for tending to Machine Spirits and laying waste to the God-Emperor’s enemies. Some bear only a few appendages, while others are great spiders of diagnostors, interface tines, drills, weapons, Plasma Cutters, and even more arcane elements that future inheritors may struggle to fully understand.
  • Bolter
  • Thunder Hammer - Iron Priests often go into battle with formidable melee weapons known as Thunder Hammers. These weapons release a terrific burst of gravitic energy when they strike an opponent, and their concussive impact is as loud as a thunderclap, from which the weapon's name originates. Enemies that survive the pulverising blow are likely to be incapacitated by the shockwave that follows. Many Battle-Brothers balance the clumsy nature of attempting to parry with a Thunder Hammer by pairing it with a Storm Shield.
