Adeptus Astra Telepathica - Adeptus Astra Telepathica and the Inquisition: The Adeptus Astra Telepathica is responsible for the operation of the fearful Black Ships. These vast, ancient vessels ply the space lanes on solar decades-long circuits of the Imperium, gathering at each planet they visit all of the Human psykers born to that world. These are interred in soul-shielded holds, and eventually brought to Terra when the vessel's holds are full, there to be judged worthy of a life in service to the Imperium, or a death in communion with the Emperor. Plenty never even make it to Terra, being judged by their keepers as too dangerous to live a minute more, even in the bleak holds of the Black Ships.Due to their mission, there is a fair amount of interaction between the Adeptus Astra Telepathica and the members of the Ordo Hereticus. One of the few obligations of Imperial Commanders is that they conduct regular psyker-purges and render up those they find when the Black Ships arrive. The Adeptus Astra Telepathica employs all manner of arcane enumerations in order to predict the number of psykers the population of any given world is likely to spawn in a single generation, and the quantity grows each year. So, when a world's offering comes up short of this prediction, the Adeptus Astra Telepathica has cause for concern. If the adepts' fears are great enough, they call upon the Inquisition to investigate matters.The consequences of a world failing to hand over its psyker population are too terrible to comprehend, and so it is not uncommon for the Adeptus to supply the Inquisitor with specialised Imperial Sanctioned Psykers, should they be needed, in order to combat the threat.Psy-cults are pernicious enemies indeed, able to dominate entire segments of a population. Other groups trade in psyker-slaves, drugging the poor unfortunates and subjecting them to all manner of ritualised trauma in order to ride the wave of thrilling madness they telepathically radiate. Others, such as criminal figures, seek to use the psykers' talents to their own ends. Ultimately however, such misdeeds always lead to disaster. An enslaved psyker escapes and wreaks revenge against all within a dozen kilometres; the cult delves too deeply into forbidden knowledge and mass possession and Daemonic incursion ensue; the unbound psyker loses control of their powers and death and insanity are unleashed.Only the greatest of Witch Hunters can hope to prevail against such foes, and even they request the aid of the Adeptus Astra Telepathica in combating their foes. In addition to such aid being provided, Inquisitors, in common with every branch of the Imperium, rely upon the services of astropaths for communications across the void. These adepts are provided to the many arms of the Imperium by the Adeptus Astra Telepathica, and pledged to the service of the organisation they serve. In the case of the Inquisition, many Inquisitors prefer to maintain the permanent services of a trusted astropath, that their communications might remain secure and uncorrupted by the actions of their rivals and enemies.Another reason for the relatively close ties between the two organisations is that a large number of Inquisitors are gifted with psychic powers themselves, and therefore were trained in their use by the adepts of the Telepathica. In fact, such Inquisitors owe their very lives to such adepts, for they might have been judged undeserving of life or too weak to control their powers, or else consigned to the Adeptus Astronomica.It is not uncommon for Inquisitors of the Ordo Hereticus to serve on board the Black Ships themselves, witnessing first hand the methods the Adeptus uses to suppress and control its charges. Arriving at a world, the Inquisitor is able to lend their aid in the gathering of the cull, to ensure that no psykers are withheld, and to make sure the Emperor receives His due.
