'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, it spread far and wide.' The Perfumers are the Lands Between's pre-Erdtree apothecaries : 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 followed every Demigod's army into Caelid, into the Mountaintops, into Liurnia, 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, whose techniques for sleep and pain-cessation became the techniques used to kill quietly. Tricia, the Misbegotten healer, is a perfumer in the same lineage who chose the opposite vocation : she dies tending the impure. The maddening boluses crafted from a wartime perfume cookbook are now sold by every nomadic merchant. A profession that once preserved life, in the canon's hands, splits into the trades of mercy-killing and madness.
