"I charge thee, foul spirit, whatever thy corrupt nature, along with all thy twisted minions now possessing this servant of the God-Emperor, by the mysteries of His holy ascension and enduring sacrifice in the sacred chains of the Golden Throne, that you tell me by some sign thy name, and the day and hour of thy departure. I compel thee, moreover, to obey me to the letter, I who am a humble servant of the God-Emperor. Depart, then, despised transgressor. Depart and burn forever in the outer darkness that awaits thee and thy benighted kin!"

Arch Exorcist

An arch exorcist of the Adeptus Ministorum

An arch exorcist is a zealous priest of the Ecclesiarchy who relishes combating the Daemonic as a holy work that follows the example of the God-Emperor Himself. They often aid Inquisitors of the Ordo Malleus in their fight against the machinations of the Archenemy. A particularly well-known order of arch exorcists operates within the Calixis Sector of the Segmentum Obscurus in the service of its Arch-cardinal Ignato.


Within the Adeptus Ministorum of the Calixis Sector, there are those priests who chafe at the political restrictions that allow only the Inquisitors of the Ordo Malleus to combat the unclean and unquiet Warp entities known as Daemons. A large proportion of those clerics who are aware of the existence and nature of Daemonkind yearn to take the fight to them, to dispel them and cast them out of the material realm and back to the myriad hells that spawned them.

The senior members of the Adeptus Ministorum are aware that there are unclean and unquiet spirits lurking within the Warp, seeking to devour the souls of the faithful. The senior clergy fear the influence of these beings, and rightly so, for they are the antithesis of all for which the God-Emperor's church stands. The Calixian Ministorum is not tasked with combating these entities: that is the role of the elite Daemonhunters of the Inquisition's Ordo Malleus. However, some within the Calixian Ministorum refuse to stand by and allow such evil to go unchallenged despite the political restrictions placed upon them.

A few senior clergy of the Calixis Sector, with the permission of the Sector Synod's Arch-cardinal Ignato, maintain a small and secretive order of specialist clerics devoted to the expelling of Warp fiends from the material realm. The arch-cardinal risks offending the powerful and secretive Inquisition for enacting such dangerous measures. He reasons, however, that in these dark days, command of a cadre of skilled and devout holy warriors sworn to destroy Daemons is a treasure beyond measurable price.

During the events on the world of Redemption when a Daemonic assault erupted, this gamble paid off. Inquisitor Octus Enoch desperately fought to avoid invoking an Exterminatus on Redemption in the face of a Daemonic incursion. Unable to procure Ordo Malleus resources due to the onset of a Warp storm at the same time as the incursion, he petitioned the Ecclesiarchy to raise Frateris Militia regiments to combat the threat. Instead the local diocese sent three arch exorcists, who proved instrumental in defeating the Daemonic assault.

To this day, Inquisitor Enoch works closely with the Ecclesiarchy when pursuing Daemonic threats and makes sure that arch exorcists are available to other members of the Ordo Malleus. When the Daemonhunters assist the Inquisitors of the Ordo Hereticus, Arch-cardinal Ignato of the Calixis Sector and other cardinals with arch exorcists among their staff often lend their services to Malleus Inquisitors seeking to strike down the enemies of the Imperium from within.

The arch exorcists use faith itself as a weapon against a Daemon. Their prayers and hymns madden and deafen the servants of the Archenemy, and their holy symbols and gestures bind them. They castigate and berate the possessed, driving the Daemon forth before them and freeing the victim -- often with fatal consequences for both.

Such is the fiery faith of these individuals that they are permitted by the Inquisition to study the foul texts of the Archenemy in order to learn the wiles of the Daemon. However, unlike the Radical Inquisitors of the Ordo Malleus, they scorn using the methods of the Archenemy against them. They know better than anyone that using such methods are inherently corrupting, eventually turning the user into that which they hate most.

Becoming an Arch Exorcist[]

Adeptus Ministorum priests who have shown a particular aptitude for defeating Daemonic opponents will be gently nudged by their superiors in the direction of Arch-cardinal Ignato's secret order of arch exorcists.

Based in an obscure side chantry of the Cathedral of Illumination which serves as the headquarters of the Ecclesiarchy's Sector Synod on the Calixian sector capital world of Scintilla, the order poses as a harmless order of choristers, devoted to study and song. Here they peruse arcane and forbidden texts and memorise hundreds of holy exhortations crafted to smite the Daemon.
