Exorcists - Chapter Beliefs: The character of the Exorcists is known to be studious, intelligent, highly honourable and above all calm outside of battle, but in war they undergo a transformation into an uncommonly aggressive force of Astartes. Their intellect is applied to rapid analysis and exploitation of conditions on the battlefield and on the decisive application of force to destroy the enemy.As a Chapter steeped in an understanding of Chaos -- and an unusual immunity to its temptations -- from the moment of each Astartes' full acceptance into the Chapter, the Exorcists are always at risk of pursuing what the Inquisition would classify as Radical solutions to certain problems, including the use of Chaos weapons and strategies against the forces of the Archenemy. Even at its purest, the Exorcists are a Chapter who will often choose a pragmatic solution to a given problem rather than remain committed to the orthodoxies of Imperial doctrine.As such, the Exorcists retain close links with the Inquisition -- both for tactical reasons and so that the Ordo Malleus may maintain a close watch on this most unusual and potentially dangerous of Astartes Chapters.Another area in which the Exorcists differ from many of their brother Chapters is their cultivation and propagation of forbidden knowledge. The Exorcists are highly intelligent and rational, and each Astartes is steeped in the lore of the Daemon and of the Warp. Each is said to know numerous wards and can recite the most powerful of Daemon-slaying texts. The teachings of the Chapter's cult focus heavily on defeating the works of the Daemonic, though it must be said that the Chapter is nowhere near as specialised as the secretive Grey Knights and regularly faces the entire spectrum of the Imperium's foes, mortal and xenos alike.Nonetheless, the Exorcists are especially adept at combating the denizens of the Warp and this is manifest in another of the Chapter's practices. The Chapter cult is divided into a number of sub-cults known as Orisons, as noted above. Each serves as a lodge of warrior-mystics within the Chapter, the members of each privy to a particular, specialised branch of Daemonic lore. When facing a threat that is the domain of a specific Orison, that group may be gathered together to confront it or to counsel others in doing so. The Orisons are not standing tactical formations and their existence does not contravene the dictates of the Codex Astartes, but they do allow the Chapter to focus specialised knowledge quickly and efficiently and thus defeat the servants of the Ruinous Powers.Given their nature, it is perhaps inevitable that the Exorcists should maintain close ties to various bodies within the Inquisition. While it is far from unusual for Chapters to have special links with individual Inquisitors or with particular sector conclaves or other groups, the Exorcists go one step further. The Chapter's homeworld of Banish hosts several facilities belonging to the Radical Plutonian Inquisitors of the Ordo Malleus, though their exact factional leanings remain a mystery to outsiders.If half of the suspicions regarding the Exorcists' recruitment and indoctrination processes are true, then outsiders believe it is possible that these allied Inquisitors and their servants adhere to one of the more Radical factions within the Holy Ordos, for no Puritan would countenance such practices.
