Fiends are the Dark Prince's hunting-beasts, daemons wrought as chimeras of insect, serpent, and nightmare. They advance in skittering packs beneath a low droning song, stinger tails poised and crushing pincers spread wide, while their soporific musk rolls ahead of them like fog. Soldiers caught in that sweet haze describe the same sensation: the battle receding into a dream from which their bodies quietly decline to wake.
Even other Hedonites give the Fiends room. Daemonettes find them graceless; Sybarites find them honest — and that is precisely the discomfort, for the Fiend is the faith with its mask removed. Beneath the silk, the perfume, and the philosophy of perfection, Slaanesh's creed is a predator's patience, and the Fiend embodies nothing else.
