The Hammer and the Soul
The Black Ships come.
They ply the myriad planets of the Imperium, at once protecting its stability and ensuring the Emperor’s continued guidance of all humanity through their constant vigilance in removing psykers from the greater population.
In their wake, they leave broken families and heretics, psykers and their kin driven by fear born of ignorance into ignoring the Imperial edict and hiding from the Black Ship gatherers.
This time, the planets of the Drusus Marches are ready. In anticipation of the Black Ships’ arrival, and in cooperation with the Ordo Hereticus and Ordo Malleus, the planets of the Marches made an early sweep of all their psykers, abducting them swiftly and covertly from their homes and shipping them to a convoy of prison ships gathered near Port Wander.
The acolytes, working under an Inquisitor of the Ordo Hereticus, are in charge of security on one of these prison ships, watching over the psykers and waiting for the Black Ships to arrive and collect their bounty.
