A psyker. To be as one chosen is to be condemned. After surviving the soul-breaking trials of the Scholastica Psykana on Holy Terra, a new weapon is forged in the service of the Imperium. Bound by iron will and the Mark of Sanction, this soul now walks the razor’s edge between absolute duty and total damnation. In a galaxy of encroaching darkness, they are a living conduit for the terrifying energies of the Warp—feared by the citizens they protect and hunted by the horrors they dare to channel. Success offers only a lifetime of shadowed service; failure offers a fate far worse than death.
