Every son of Mortarion reveres disease, but the Biologus Putrifier makes of it a life's work. Part battlefield chemist, part fervent disciple, he is charged with the creation and perfection of new contagions, brewing them within his own corrupted body and within the alembics and phials that hang clattering from his war-plate.
In battle the Putrifier is a grotesque and eager figure, scuttling through the ranks of the Plague Marines to fling brittleglass spheres that shatter against armour and shield alike, drenching the enemy in bespoke plagues. Where a foe yet lives, he closes to drive the long needle of his injector pistol into exposed flesh, seeding a fresh sickness that he will later study with clinical delight.
To fight beside a Biologus Putrifier is to fight within a living laboratory, and the plagues he distributes lend the blades and bolt-shells of his brethren a keener, more virulent edge. He regards every battlefield as a proving ground and every corpse as data, another small confirmation that the Grandfather's gifts are without limit, and that death, properly cultivated, is only the beginning of a longer and more useful existence.
