Exceptional mortal Champions of Chaos are sometimes granted a Collar of Khorne by the Blood God to ensure no thrice-cursed psyker will lay such favoured servants low with his eldritch trickery. In the case of mortals, the favour of the Blood God does not always manifest as a physical collar; for instance Khârn the Betrayer, the most favoured of Khorne's current mortal servants, is utterly immune to any psychic power, yet his neck remains unadorned.
