Psyker hero unit that summons Daemons and supports allies.
Masters of Possession lead warbands of devoted warriors in pursuit of untold power. These sorcerous figures have mastered the darkest and most blasphemous lore: the art of using hosts of living flesh to house daemonic spirits. It is they who perform the profane ceremonies of binding that imbue the Daemonkin with their warp-born power. Gouging a breach in the fabric of realspace, the Master of Possession draws a willing entity from the immaterium, channelling its terrible energies into the body of a supplicant or the chassis of a war machine. So thoroughly are these dread figures steeped in blasphemous sorcery that where they walk, reality itself recoils.
