See the Galaxy They Say - Should Have Joined the Navy
This Iron Priest has been the Forge Master of 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 Isles of Iron, he is not nearly close enough to the teaching of Mars as many of the Techmarines who serve under him wish. The Iron Priest has adorned most of the Fortress’s 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 ha yet been able to oust him. His fervent hatred of alien technology is now infamous and every piece of xenotech adopted into the Deathwatch arsenal since his arrival has been so grudgingly.
