Inquisition - Role of the Inquisition: The Inquisition is immensely powerful, and the only individual that is exempt from its scrutiny is the Emperor Himself. If he has good cause, an Inquisitor may demand any service from any Imperial citizen, up to and including the High Lords of Terra.The Adeptus Custodes who guard the Emperor's palace and person are exempt from conscription, because their duty to the Emperor is clear and unchanging. When it comes to the Adeptus Astartes, Inquisitors often show some discretion, as Space Marine Chapters are often willing to come to blood over any infringement on their Emperor-granted autonomy.However, not even the Adeptus Astartes are immune from the Inquisition's scrutiny and justice, and entire worlds have been destroyed in order to cleanse them if they were deemed traitorous.Inquisitors also have absolute power to judge and execute supposed Heretics, mutants, unsanctioned or rogue psykers and the like, with no appeal save the intervention of another Inquisitor. Practically, all possible verdicts are death sentences, although the means by which they are achieved differ.Traitors, the worst grade of offenders, are considered irredeemable and will be quickly executed. Heretics may be redeemed, often after considerable amounts of torture, and may receive absolution through death in service to the Imperium. This service may consist of arco-flagellation, conscription into Imperial armies, becoming the operator of one of the Adeptus Ministorum's Penitent Engines or, in the case of penitent psykers, being sent to Holy Terra to become new psychic fuel for the Golden Throne and the Astronomican.Certain Traitors deemed useful to the Inquisition may in extremely rare cases be mind-scrubbed, their old memories and identity erased and replaced with one loyal to the Inquisition. If it is beyond their means to track down and kill a particular individual or organisation, an Inquisitor can simply declare the offending entity Excommunicate Traitoris, stripping them of whatever rights they may have had and as such marking them as a target fit for extermination by any and all loyal servants of the Emperor.If the Inquisitor deems it necessary he or she can attach an official stigma to a dangerous Heretic, Traitor or alien species. Each of the major Ordos has a different official stigma which pertains to their primary enemies. These stigmata include the Extremis Diabolis for the Ordo Malleus, the Xenos Horrificus for the Ordo Xenos and the Hereticus Abomini for the Ordo Hereticus.The Inquisition will also use its delegated power from the High Lords of Terra to declare "tainted" Space Marine Chapters or other Renegade Imperial military units or individuals Excommunicate Traitoris. The Chapter or other unit will then usually be hunted down by the Grey Knights or the Sisters of Battle, usually resulting in the Chapter fleeing to the Eye of Terror or the Maelstrom (if it has not already done so).The Soul Drinkers Chapter was an exception, as they still believed themselves to be loyal servants of the Emperor, and continued to defend the Imperium until their destruction, even though they were no longer part of it.Young psykers who have not worked against the Imperium or used their powers much will usually be repeatedly tested, and if they are young, strong and pious enough, may be taken in by the Black Ships of the Inquisition to become a Sanctioned Psyker or even an Inquisitor if their abilities are strong enough.The requirements are strict and many will be found wanting. Those that fail the Inquisition's tests will either be executed or used to power the vast psychic beacon of the Astronomican, their lives sacrificed for the ultimate good of Mankind to sustain the Golden Throne which keeps the Emperor alive.
