The Exorcists are a Space Marine Chapter founded during the Dark Founding and is one of only two canon Chapters known to have come from that Founding (the other being the Death Spectres). Their shtick is basically "reasonable Grey Knights." Seriously, check out the table below.
|Recruit from Psykers, who are pretty much Daemon-chow.||Recruits are possessed and exorcised of Daemons, making them invisible to Daemons.|
|Kills or mindwipes everyone who sees them||Don't murder innocent civilians for being saved by them|
|Recruits from an already rare population and only 1 in a billion survive||Recruits from an entire planet, and two extra scout companies offset the lethality of Daemonic Possession Therapy|
|Only fights Daemons||Actually fights non-Chaos enemies on a regular basis|
|Secret base (Titan, moon of Saturn) is in one of the most overpopulated planetary systems in the Imperium (thought note: if the warp gate under the golden throne somehow flares up beyond what even the Adeptus Custodes can normally handle, the Grey Knights are a quick warp jump away,)||Secret base (Banish) is in the middle of a forbidden sector|
They have ties to certain factions in the Ordo Malleus; it's never been mentioned which ones, but they're almost definitely Radical. Although they largely follow the Codex Astartes, they also have two extra Scout companies (exorcism is a haphazard process, after all), and they have special cross-Chapter organizations called Orisons. The Orisons invite exceptional warriors from across the Chapter to study a particular style of combat. The Chapter also doesn't like to stick to any one tactic for very long; indeed, their Chapter Tactics allow you to choose a different Chapter's Tactics before every battle! They also have an exceptionally large fleet (including three Battle Barges), which allows them to respond (relatively) quickly to any emergent threat and remain on extended operations much longer than other Chapters. Technically, the Exorcists recruits are not exorcised of daemons. The recruit must kick the daemon out of himself through sheer willpower. Otherwise he is killed by the other Astartes.
- Silas Alberec: The Brother-Captain of the Third Company, he is really fucking huge, like Ogryn or maybe even Primarch sized. He is slated to be the next Chapter Master. He wields an artifact mace known as the Hellslayer, which is made of a material so heavy that only his brutish strength can lift it. He led the Exorcist forces in the Badab War. He is also the only in-game playable character for the exorcists, and he (awesomely) auto-wounds daemons at S10 ap2 master crafted. Hilariously, he can bring more pain against daemons than Kaldor Draigo could ever hope to.
- Enoch Trismegistus: The first Chapter Master of the Exorcists. The Orision known as the Enochian Guard is named after him. With two companies, had a 97 to 1 kill rate, with only 1% of the Exorcists getting recorrupted, so two marines total.
- Darrion Rauth: A member of the Deathwatch from the short stories Headhunted and Exhumed (written by Steve Parker). An asshole who really hates psykers, though he goes from "asshole" to "creepy" in the prequel novel Deathwatch.
- Waite Ryder: Master of the Fleet. Saved the life of Carab Culln, Chapter Master of the Red Scorpions.
