'Glass bottles used by perfumers. Used to seal various scent compounds. Essential vessel for crafting perfume items. The art of perfuming was once jealously guarded in the capital, but after the perfumers were drafted into service during the Shattering, the art became widely practiced throughout the Lands Between.' The Perfumers are the blessed apothecaries of the Erdtree capital: a guild of capital-trained scent-craftsmen who blended healing tinctures, mood-altering vapours, and incendiary mists from the same alembics. Before the Shattering they were a cloistered Leyndell elite, jealous of their formulas. Then the demigods went to war and the perfumers were forcibly drafted as battlefield medics. They entered the battlefields of the Shattering, trading their aromatics for poisons and explosives, and the secrecy of their old guild was lost to wartime exigency.

'Robe worn by the Omenkillers, butchers of twisted conscience. Its thick apron is worn in remembrance of Rollo, the progenitor of the Omenkillers and a perfumer of antiquity.' The Perfumers' canon is the canon's quiet story of professional ethics. The Omenkillers, butchers paid to euthanize Omen children at birth, descend from a perfumer named Rollo, who imbibed a physick to rid himself of emotion, thus enabling his nightmarish labor of hunting the Omen. Tricia, healer of the Misbegotten and the impure, is a perfumer in the same lineage who chose the opposite vocation: she watched over the dying so they could pass free of pain. The maddening boluses are crafted from a recipe left behind by a perfumer who served in the Shattering. A profession that once preserved life, in the canon's hands, splits into the trades of mercy-killing and madness.
