A Primaris-rogue Witch is an unsanctioned psyker within or without the Imperium of dangerous psychic potential. Many are affiliated to the Ruinous Powers. Sometimes primaris-rogue witches lead Chaos Cults and some are even the demagogue-leaders of warbands of the Lost and the Damned. The most miserable of these creatures are open portals for the powers of the Warp, forming doorways into the mortal world and potent pawns whose powers are easily twisted to suit the Neverborn's malevolent ends.
