Primaris Psyker - Primaris Psyker: A Primaris Psyker, also known as a "primary-psyker," "battle-psyker," or "psyker-lord" among the servants of the Emperor, is a powerful Human Sanctioned Psyker who plays an ordained role as a servant of the Imperium of Man, for they possess the willpower to fully control their abilities and not become a danger to others. These rare and extraordinary individuals serve in the regiments of the Astra Militarum and among the ranks of the Inquisition and wield the destructive power of the Warp as a weapon to smite the enemies of the Emperor.With a single thought they can conjure forth lightning that leaps from their hands and surrounds their body. With but a gesture, the psyker hurls these bolts of aether-energy at their opponents, burning the foes' synapses and searing their flesh from their bones.Mysterious and aloof, Primaris Psykers are treated with a mixture of awe and fear, but most of all, suspicion by the superstitious soldiers of the Imperial Guard, with whom they often serve. Though their presence is utterly abhorrent to all right-thinking Imperial servants, their ability to combat the blasphemous magicks of the xenos and Heretics usually outweighs the natural revulsion all their comrades feel at the inclusion of psykers in the ranks of the Imperial Guard.A Primaris Psyker is typically attached to a high-ranking Astra Militarum officer who can direct the psyker's powers as the situation necessitates, providing psychic support to the troopers on the front line. A battle-psyker marches to war in a uniform daubed with wards and sigils of power. A Primaris Psyker carries a Force Staff made of rare woods and precious metals that can channel the psychic energy of the wielder.A psyker can focus their prodigious mental strength through such a psycho-reactive staff, transforming it into a searing weapon that glows with a barely contained, otherworldly power capable of cutting through reinforced ceramite and ripping the life force from those it strikes.Of all the psykers judged under the uncompromising gaze of the Inquisition, only those whose mental fortitude and willpower is great enough have the merest glimmer of hope of becoming a Primaris Psyker in the Astra Militarum. Battle-psykers are by no means the most powerful of their kind, but even so, they walk a fine line between service to the Emperor and eternal damnation.Every time they unleash their powers they risk predation from the denizens of the Warp -- Daemonic entities swarm to their bright psyker-soul like moths to a flame. Several fail-safes are therefore built into a battle-psyker's wargear. Complex micro-circuitry and neuro-active wiring are connected to psychically-attuned crystals embedded in a psyker's hood or collar, designed to bleed away excess Warp energy.Such precautions are not limited to the psyker's wargear alone and most have undergone cranial surgeries to implant cybernetic neural inhibitors that limit the danger of Daemonic possession -- however, such devices tend to blunt the psyker's innate power as well.When combined with a lifetime of training, a Primaris Psyker has a reasonable chance of avoiding powerful psychic enemies and resisting Daemonic influences. For those who prove to be too weak, however, there is always the final safeguard, in the shape of the smoking muzzle of a commissar's Bolt Pistol.
