History Headscratchers / CiaphasCain

* In "Sector 13," Cain's first attachment (12th Field Artillery) are cleansing Keffia of Gene-stealers, those little so-and-so's that use {{Unwitting Pawn}}s to spread the mutations to future generations. There is at least one continent infested, in a war of attrition. So then why the FRAK are the soldiers being allowed into the RedLightDistrict? It's [[WhatAnIdiot begging]] for contamination! Dozens of soldiers have to be [[WhatASenseLessWasteOfHumanLife exectuted]]! [[TooDumbToLive And yet...]]

** A Guard regiment is expected/required to have at least one Commissar assigned to it. Larger regiments would preferably have more, but at that point it's a matter of logistics and clerical oversight. With Cain and the 597th, the whole reason he was assigned was because they'd lost all of their Commissars beforehand, and after he got there, he put things in line well enough that he and regimental command didn't see any reason to request more, and with him already having quite the reputation, the Commissariat and Imperial Guard High Command probably didn't think they needed to anyways.

** A more mundane explanation is that Lord-Commissars didn't exist in the lore at the time. Lord Commissars first appeared in the 5th Ed rules in 2008, by that time there were already six Caiaphas Cain novels, including the one where he'd already retired to a teaching position at a Schola.

* Dictionary.com defines memoirs "as a record of events written by a person ''having intimate knowledge of them and based on personal observation,''" and suggested synonyms are "journal, recollections, reminiscences." From Wiki/{{Wikipedia}}, one writer states "a memoir is how one remembers one's own life, while an autobiography is history, requiring research, dates, facts double-checked." Why does Amberley, who has described "the Cain archive" as memoirs, complain ad nauseum about how Cain's writing focuses on his own experiences to the exclusion of the bigger picture? Isn't that what memoirs are for? Cain's memoirs never purport to be an autobiography or a historical document, and Cain himself probably never expected anyone other than Amberley to ever read them (and maybe not even her); why is she surprised that something written for his own benefit focuses on him? This reaches Wallbanger territory for me when she criticizes him for not describing events/battles on the other side of the planet that he took no part in (as if she expected him to write a referenced history), especially when the battles in question were extensively covered by historians and Cain would not know anything that would add to those histories.

[[WMG: Sister Julien.]]

Julien is a ''man's'' name.

* And? People end up with weird names.
* It's probably supposed to be [[http://en.wiktionary.org/wiki/Julienne Julienne]], with the extra letters discarded. "C[a]iaphas" and "Bro[c]klaw" probably follow the same kind of logic.

* It's the year 40,000 and there have been a couple of apocalypses along the way. Some language drift over names is to be expected. Hell, there are names that have switched between masculine, feminine, and unisex drastically over even the ''last'' century.

* Also, the Adepta Sororitas are supposed to be analogous to real-life nuns, and some nuns take masculine names as part of their religious custom. See [[http://forums.catholic.com/showthread.php?t=95933 here]].

[[WMG: How is Jurgen Pronounced?]]

I've always thought it as being pronounced "Yergen" like the common German name Jürgen, in keeping with the sort of pseudo-German theme naming of the Guard. But I'm wondering why, if this is so, there's nothing to notify the average reader, who wouldn't pick up on it, of this. Is there an official pronunciation that will hold me off until Dead in the Water?
* He's Valhallan, so the Scandinavian pronunciation "Yörr-en" might also be appropriate.

* I've always pronounced it "Jergen", mainly because it seems that, given his lack of hygiene, naming him as a reference to a brand of soap (Jergens) would be the kind of ironic StealthPun that Creator/SandyMitchell would make.
* The "[[http://www.blacklibrary.com/all-products/Dead-in-the-Water.html Dead In The Water]]" audio drama uses the German "Yergen" pronouncation, so I think that we can consider that the proper way to say it. Of course, the spelling naming him like the soap brand probably is a pun as well, though purely a written rather than spoken one.

[[WMG: Cain's childhood]]

The lack of information about Cain's childhood is suspicious in its absence. The fact that he was educated in the Schola Progenium suggests that he was the child of Imperial servants, either military officers or someone in an official civil position, and records of them should exist somewhere just to allow him entry. Unless there was some special circumstances that got him in, but even that should have a record noting why. Further, when he was admitted to the Schola, his file should at least indicate where he was picked up, and by whom. He may have been recruited away from his hive of origin, but given the mobility oppertunities for someone, especially a child, born into the lower to mid levels of a hive city, it is unlikely he could have gotten far. It is also possible that what records do exist were sealed or removed by order of the Inqusition, but if they were to do that they would at least put falsified files in their place, as Cain's large public profile would only draw more attention to the missing documentation. Given the RightHandVersusLeftHand operation of the Inquisition, Cain's association with Inqusitor Vail, and the fact that she is publishing Cain's memiors (for distribution only within the Inqusition,) it seems likely that some other Inqusitor would get curious enough to start digging, and finding nothing at all would set off more alarms than finding something bland.
* The Imperium has been known to forget about entire planets due to rounding errors. This is no big deal. That being said, I have a theory of how the son of two cowardly troopers could become a commissar (assuming Cain wasn't lying about their status): Cain's luck is inherited. In other words, his parents were trying to run from something, got killed, and looked like they died heroically for the Emperor.
* Also it's worth recalling that Sholas described in codexes as a places that does mind-scrubbing rutinely. Gaunt remembering his family and saving heirlooms is actually a big canon error. So it's quite possible that Cain isn't actually _knows_ anything about his family, making things up for his convinience, basing them on assumptions, and with bureaucratic hell Administratum is it's possible even Vail doesn't have time or beliving it's important enough to drop everything and actually dig hard, not just routine checks when something new arise.

[[WMG: Night Vision]]

Uh, I know that this is a CrapsackWorld, nobody understands technology at all, and this is minor nitpick, but Cain takes it as AMAZING when the Tau have like, night vision and thermal sights on their vehicles. 40 centuries into the interstellar future?

* Cain's adventures happen mostly out on the Eastern Fringe, which is sort of the ass-end of the galaxy and is much less developed or densely settled. With less infrastructure, the night vision gear you might see Stormtroopers or elite light infantry getting issued elsewhere are nonexistent.
* Tau blacklight tech is something distinctly different from thermal sensors. Imperial Guard units do have thermal sensors (referred to as "heat-see").
* You also have to keep in mind the wide gulf in technology and beliefs about technology between the Imperium and other races. To the Imperium, anything more hi-tech than the stuff they have now is heretical "technosorcery" since they don't understand the science behind it, whereas it's just equipment to the other races.
* I think that they do have such devices, the Imperium is just very... particular about them. In a lot of the cases with the Tau's technology, what the Adeptus Mechanicus (and anyone educated about technology from them) is horrified by is less that the Tau's technology is advanced, and more that it is so advanced without showing the proper obsequious to the Omnissiah in its construction. They tend to think of their own devices as operating on a kind of animism, believing that it has a soul and is allowing its user to make use of it, while Tau constructs are soulless constructs. The idea that a construct could take the place of "techno-magic" is terribly off-putting to them.
* maybe he was still getting used to the idea that these xenos were this advanced ( night-vision is probably very advanced tech, and cain is (almost) just as xenophobic as the rest of the imperium).

* Correction: the setting is set 400 centuries into the interstellar future, not 40. 40 centuries would be 4 millenia, when it's the 41st millenia (nearing the 42nd millenia/already the 42nd millenia).
[[WMG: Why isn't Jurgen a quartermaster?]]

This has been bothering me since starting reading the series but why has Jurgen not been promoted to a job as a quartermaster? The guy is so skilled at scrounging that he could probably find those Baneblades that General Stubbs lost! I get that he wasn't well liked by the Valhallans but I'm pretty sure they would get past that if Ciaphas Cain HERO OF THE IMPERIUM vouched for him.
* Short answer: Because he's Cain's personal aide, and Cain likes it that way. 'Nuff said.\\
\\
Slightly longer answer: The very fact that Jurgen is anything other than a low-rank soldier serving in an artillery unit is a very fortuitous fluke; he was an undesirable soldier assigned to an equally unappreciated wet-behind-the-ears commissar as a practical joke. Both his personal hygiene habits and his pariah gene (which both make him unsettling to ordinary humans) would probably make him repulsive enough to most other people to effectively can his chances at promotion through normal channels.\\
\\
The fact that Cain's personal aide ''is'' a blank keeps Cain shielded from adverse psyker influence or probing, his obstinate personality and repulsive countenance are handy at keeping at bay anyone Cain doesn't want to talk to, his dedication to his work alleviates much of Cain's workload, and finally there's that melta that he always carries around.\\
\\
Amberley Vail also prefers that Jurgen stay with Cain because it makes things convenient for her as well; whenever she suspects she needs a blank handy, she can just pick up Cain, and Jurgen naturally always accompanies the commissar. It would be perfectly natural for an Inquisitor to ask for a '''HERO OF THE IMPERIUM!!''' to help her out, and the fewer people who know about Jurgen's secret, the better.

*** Although given the general nature of the 40K universe it seems likely that most quartermasters skim a bit off the top and no one really cares unless they get too blatant about it. In fact Jurgen basically says as much in ''The Smallest Detail'' expressing surprise that the quartermaster thought he'd bother to report a bit of pilfering.

[[WMG: Why hasn't Vail gotten her own book yet?]]
This is purely me wishing for things that probably where never planned but why hasn't Amberly gotten her own spin off? It would be awesome.
* She's too busy editing Cain's memoirs to write her own.
* All the best parts are State Secrets. She could could tell you about them, but then she'd have to kill you.
* Tell that to {{Literature/Eisenhorn}} and Literature/{{Ravenor}}. Actually, though, it's probably ''Mitchell'' who's too busy churning out those gosh-darn Cain books.
* Probably because a book on Amberly Vail wouldn't be as interesting because she tends to act like a competent Inquisitor, where as Eisenhorn and Ravenor would be a whole lot more boring stories if they didn't make the situations they were in about a thousand times worse by making lots of rash and inept decisions.
* Not a book, but Mitchell wrote a Vail [[https://www.blacklibrary.com/warhammer-40000/quick-reads/hidden-depths-ebook.html short story]].

[[WMG: Why didn't the Necrons take Jurgen to be turned into a Necron Pariah?]]
He has the pariah gene and they had plenty of chances to snatch him (e.g. when he and Cain were the only survivors of the attempt to blow up their teleporter in Caves Of Ice). Was he just too scruffy, even for them?
* Probably because ''they never caught him''. It's kind of hard to turn someone into a Pariah if you can't ''catch'' them to turn them into one.

*** Except ''they didn't catch him'' when he was in the middle of their lair, and there's no evidence that the Necrons can just spot a Blank/Pariah candidate.
*** There is a difference between blanks and pariahs. Blanks are a natural development, while pariahs are created by the decievers Pariah gene. the effects of pariahs are also ''way'' stronger than those of blanks, just as the side effects (to the point that pariahs are so off-putting they are usually lynched ''as children''). Jurgen is just a normal blank, so he probably isn't "good enough".
*** Which is now almost worthless information, because Game Workshop has a horrible time of making things like this canon and keeping it canon. More than a few sources say pariahs and blanks are the same thing now (perhaps becasue the writers didn't know the difference and Game Workshop didn't clean the air.)
* That bit of fluff of human untouchables being turned into Necron Pariahs didn't exist at the time (Caves of Ice was released in '04, DoW: Dark Crusade, which said Necronized blunters were the Pariah's, came out in '06), and the way that the Pariahs acted in CoI sort of implied that Mitchell was treating them as though they operated on psychic powers or somesuch.

[[WMG: Sulla's Memoirs]]
At the end of ''Caves of Ice'', Cain mentioned that Amberley spent a great deal of time debriefing the 597th and telling them to never say what they found under the mines of Simia Orihalcae. Yet in Sulla's memoirs, there are descriptions of Necron warships engaging the Gargant. This is a direct violation of an Inquisitorial order. Why wasn't the manuscript pulled? Did Sulla get in trouble for that?
* IIRC Sulla's memoirs were pretty vague about the actual nature of the Necron ships, pretty much only describing their look and what their weapons did (or something like that). Perhaps that was vague enough that the inquisition saw no reason to pull it, as anyone who recognized them would have to already have known about Necrons and anyone who didn't would just assume it was an abstract description of some Imperial tech.
* The memoirs were also published at a time when the Necrons had moved from shadowed threat to full blown menace in many areas. By this time the cat was well and truly out of the bag.

[[WMG: Has Cain Actually Shot Anyone?]]
And I don't mean anybody in combat, I mean as a commissar doing his duty to remove undesirables from Imperial service. I finished reading Death or Glory not too long ago, and I vaguely remember Cain mentioning he could exercise his commissarial powers and shoot someone for insubordination as a worst case scenario. Now I know that Cain has the presence of mind to keep his people in line with loyalty rather than fear, but he has considered executing people from time. Now my question, is has he ''actually'' executed anybody yet?

[[WMG: [[ItsAllAboutMe Amberley's complaints]] about Cain's memoirs]]
Dictionary.com defines memoirs "as a record of events written by a person ''having intimate knowledge of them and based on personal observation,''" and suggested synonyms are "journal, recollections, reminiscences." From {{Wiki/Wikipedia}}, one writer states "a memoir is how one remembers one's own life, while an autobiography is history, requiring research, dates, facts double-checked." Why does Amberley, who has described "the Cain archive" as memoirs, complain ad nauseum about how Cain's writing focuses on his own experiences to the exclusion of the bigger picture? Isn't that what memoirs are for? Cain's memoirs never purport to be an autobiography or a historical document, and Cain himself probably never expected anyone other than Amberley to ever read them (and maybe not even her); why is she surprised that something written for his own benefit focuses on him? This reaches Wallbanger territory for me when she criticizes him for not describing events/battles on the other side of the planet that he took no part in (as if she expected him to write a referenced history), especially when the battles in question were extensively covered by historians and Cain would not know anything that would add to those histories.
* It's probably less complaining for complaining's sake and more a reminder to her fellow Inquisitors that Cain's memoirs, which in some cases are the ''only'' remaining accounts of certain events, are not necessarily completely unbiased.

* Amberley isn't writing memoirs. She's using Cain's memoirs as the primary source for the events surrounding his actions with corroborating sources to back them up and provide context. Most memoirs actually do attempt to provide some context and structure, whereas, going by Amberley's notes, there's almost no structure at all to Cain's memoirs. He's literally just typing these things out in stream-of-consciousness ramblings which would make any historian trying to edit and structure them into something useful throw a serious conniption.
* Amberly isn't publishing Cain's writings just for fun, she's using it to educate fellow Inquisitors, which means she needs the commentary and background that Cain never provides. Also, Cain is patterned after Flashman, which is written exactly the same way -- Flashman writes stream-of-consciousness style, while Fraser essentially cleans up after him with the intent of explaining all the useful details that Flashman leaves out. The background, not so much, as Fraser does not insert things like news stories or battle reports, but the Flashman books are not ''just'' the wacky adventures of a despicable character. They're as much ''historical'' as ''fiction,'' which is one of the reasons they are sometimes mistaken for nonfiction.

[[WMG:Blank Breeding.]]

Blanks are extremely useful against Warpspawn and are so rare, psykers are a dime a dozen in comparison. So why isn't there a program to breed more of them?
* Jurgen's....personality problems aside, getting enough booze and credits to seal the deal shouldn't be that hard.

*** The Death Korps of Krieg have cloning tech right? A cloned army of Blanks has got to be useful.
* Blanks were added to the human gene pool artificially by Filthy Xenos; Filthy Xenos that were trying to harm the True Enemy, but Filthy Xenos nevertheless, and everybody knows they can't be trusted and have ulterior agendas. Use the blanks as they pop up, but don't encourage them to multiply unnecessarily, that plays into the Filthy Xenos hands more than the already questionable status quo.

* Also, Blanks make people extremely uncomfortable in their presence, a whole group of them probably induces suicide in the handler or something.
* The surprise factor is largely the reason they have been so useful, as is the fact psykers and warpspawn are actually still extremely rare. They happen to appear often in the fluff because when they do appear, it is often something big, which is what the fluff tends to focus on. In addition, the Imperium did have an entire military organization composed of blanks, the Sisters of Silence. Outside opposing the Thousand Sons when they were still a full force legion, they never were amazingly useful for the sheer insane quantity of effort it took to amass them.
* Probably for the same reason there isn't a Psyker breeding program (aside from Navigators, but they are an entirely psychic subspecies of human and require an incredibly complicated breeding regime to keep from dying out as is). It's a random gene that has an incredibly low chance of showing up at all, so it's not unreasonable to think that breeding two blanks together won't guarantee a third blank, just like pairing two blonds together won't guarantee a third blond.

[[WMG: Letting Soldiers out to [[BoldlyComing Play]] on Keffia]]

In "Sector 13," Cain's first attachment (12th Field Artillery) are cleansing Keffia of Gene-stealers, those little so-and-so's that use {{Unwitting Pawn}}s to spread the mutations to future generations. There is at least one continent infested, in a war of attrition. So then why the FRAK are the soldiers being allowed into the RedLightDistrict? It's [[WhatAnIdiot begging]] for contamination! Dozens of soldiers have to be [[WhatASenseLessWasteOfHumanLife exectuted]]! [[TooDumbToLive And yet...]]
* You are aware that this is the Imperial Guard, right?
* It's entirely possible that the settlement had been investigated before, but that whoever had done so was suffering from a bad case of "It's been a long day, I hate this job, and I've been doing it for months. I don't see anything obvious, so frak it, let's call it a day."
* Or the investigators were invited into a dark back room where they either got a briefcase of cash or (more likely) an implant wound in the chest.
* It was likely judged an acceptable risk for morale reasons, after the area was naturally inspected and cleansed. The soldiery ''needs'' time to rest, relax, and amuse themselves. It's one of the few things that can keep them disciplined.

[[WMG: Why does Vail hate Sulla's writing?]]
While...''fervent'', it's not really horrible. Just melodramatic.
* this is Vail, she's a very no nonsense type, the style might just bother her that much.

* Vail will have also had to plough through Sulla's memoirs in their (no doubt lengthy) entirety, not just the short extracts repeated for context. Possibly repeatedly, if there's no index.

[[WMG: Jurgen's blank powers]]
In the Eisenhorn and Ravenor novels, blanks working with the Inquisition are routinely issued limiters which let them turn their psychic dampening powers off so that they can work alongside psykers when necessary. Why hasn't Amberley ever tried to get one for Jurgen? Was the technology needed to create them lost in the roughly half a millennium between the end of their careers and the start of Cain's?
* Half a millennium is plenty of time for it to become LostTechnology (particularly in the 40K universe). It might also be that the few people who know of Jurgen already know of his disposition. Having it almost magically change would draw attention to him. Plus keeping him active all the time protects Cain from having his mind read (and thus protects his reputation and many, many inquisitorial secrets).
* Both Eisenhorn and Ravenor are psykers, and use their powers quite extensively (Ravenor more so). It makes sense for them to limit their pet blanks range (Though I never remember Eisenhorn doing so) so they can actual function (Especially since Ravenor may flat out die without some of his psyker toys in the long term). Cain nor Amberley have this problem. It can also be noted that Jurgen's blank range seems to be much shorter then most other blanks.
* Eisenhorn and Ravenor were both written by Dan Abnett, who, let's just say took certain liberties with "blanks." For comparison, Alizabeth's powers in Eisenhorn are used similar to Spear, the Black Pariah. Spear was probably the most powerful Pariah to have ever existed to start with and he was bonded to a Chaos Daemon and his powers did not work without a sample of blood from the Psyker. So, Alizabeth in Eisenhorn is more powerful than an assassin capable of posing a direct threat against the Emperor of Mankind while he was still alive and well.
* Amberley wants to keep Jurgen's blank status relatively secret, and giving him a limiter would make him stand out a lot more.

[[WMG: Genestealer research]]
I can understand wanting to research captured genestealers and frozen tyranids to figure out the best way to fight them (YMMV on whether or not doing so is a good idea, but the logic is valid enough to warrant considering it), but what possessed them to put the research facility on ''a forge world''? If anything went wrong, a hive fleet would turn up and destroy a world that was the Guard's primary source of armaments for the subsector. Why didn't they put the facility on some minor moon or space station in the middle of nowhere with virtually no biomass outside of the beings in the facility to be eaten and nothing of value to be lost other than their research data?
* Adaptus acolytes don't tend to think these things through (c.f. their reactions to Necrons) and forge worlds are the sorts of places they like to hang out. When you remove those pesky strategic and human elements and only pay attention to what techpreists actually care about a forge world makes sense (better infrastructure, plenty of space, little biomass in the wild for the tyranids to eat if they escape, plenty of other techpreists to brag about your work to, etc).
* The defenses a typical forge world would have, probably makes it safer than trying it in the middle of nowhere. Also, I doubt they'd be shy about vaporizing chunks of their own world to contain an outbreak problem.
* Also keep in mind that the person in charge of the research had been secretly implanted before the research even began. No doubt she used her influence and position to convince everyone else that a Forge World was the perfect place to conduct her research.
* As for the higher echelons, they refer to their resident expert(s) on the matter: the (unknowingly) implanted project lead and the Reclaimer apothecary. Besides that, the tech priests try to cut down on logistical issues. Moving their expert, his/her equipment, and provide a steady supply of resources to a remote location would prove costly and waste resources. On top of that, said expert also has to deal with the local ambull population (a minor problem in comparison, but still important) and studies related to them. The facility also needs protection, a job filled by their trusted Skitarii forces. Remember that the forge world was lightly defended because the Magos realized the Imperial Guard needed the munitions they produced. Regiments regularly moved to resupply at the planet and the Adeptus Mechanicus used them as impromptu defense units. Moving the planet's few, full-time dedicated Skitarii troops would be unwise in the extreme. Finally, the facility was moved to a remote location and proper precautions were taken. The only problem was the aforementioned infected Tech Priest and who would consider that a possibility or the possibility that the Tyranids would spend the next 60 years waiting for a Hive Fleet to come by. The main failing here seems to be that the workers at the facility were never subjected to regular DNA screenings. At the very least, the workers should have been screened before their DNA was inputted into security access, biometric databases before they were brought in. Which leads to another question, why weren't they screened at the start? Some of them had been on the extremely dangerous ''Spawn of Damnation''. Infected serfs were brought back for study and they had to have been screened. Why weren't the people who brought them in screened as well?

[[WMG: Why hasn't Cain been promoted?]]
According to [[http://warhammer40k.wikia.com/wiki/Commissar this]], the Commissariat does have a rank structure, with several levels above the standard Commissar, including Commissar-Captain, Colonel-Commissar, Lord-Commissar, all the way up to Commissar-General. Given Cain's heroics, and the fact that he often advises Lord General Zyvan, you would think that Cain would have made Lord-Commissar by now, if not Commissar-General. Even by the time of his retirement, he still seems not to have been promoted above the level of ordinary Commissar. For that matter, why hasn't Cain ever replaced his chainsword with a power sword?
* I don't know about the [=WH40K=] universe proper, but; The footnotes in ''The Greater Good'' and ''The Last Ditch'' mention L-C is an informal title and Cain would probably qualify as one even though he refused to be addressed as one (earlier books note that the Commissariat is made up entirely of equals; only a tribunal of several commissars can pass judgement on one of their number). Another footnote mentioned that Commissar-Generals (like Gaunt) were rather rare and that, rather than being a higher rank, they were Commissars who were also Generals (i.e. they held a command post within the imperial guard chain of command as well as their role as ThePoliticalOfficer which was outside it).

*** Because it's one of those things that [[DependingOnTheWriter depends on the writer]]. The use of Commissar-General, Commissar-Captain and Junior Commissar are (as far as I can recall) pretty much restricted to the Literature/GauntsGhosts novels. The title of Lord-Commissar is used in the actual Guard Codex but even there it's more of an honorific for a senior Commissar than an actual rank. The wiki pretty much lists all ranks mentioned in any source with no real indications of where they originated. The depiction of the Commissariat's organization in the Cain novels is pretty close to the way that it's depicted in the rule books. Alternatively, if you want to combine all sources, keep in mind that the Cain novels take place approximately 150 years after Gaunt's Ghosts and are set on the other side of the galaxy (the Cain novels are set in the galactic east while the Sabbat Worlds Crusade was to the galactic west). Given the distances involved (both in time and space) it's not unrealistic to assume that the portion of the Commissariat that Cain works for is organized differently than the portion that Gaunt works for.
*** Of the several 'ranks' mentioned in the wiki, only six are related to Commissariat. Cadets are in training, Juniors are are basically probationary Commissars, Commissars are just Commissars, and Captain through Lord describe positions a Commissar holds, rather then an actual rank. It's kind of like how a Captain of a ship doesn't necessarily have to be ranked as a Captain - If a lieutenant is is charge of a naval ship, he's stilled referred to as a Captain. As a Commissar who seems to have spent the vast majority of his time on the front lines in a combat unit (The exception being when Cain was based at Commissar headquarters, where he never seems to have been in charge of anything or anyone), Cain simply was never in a position to claim a title.
*** Of note, however, is that Cain does describe a method of judging 'seniority' (A common occurrence in real military situations where people of the same rank may be required to submit to one another, based on position first, and seniority if that fails). Basically, length of service, commendations, and position are added together somehow to figure out who's 'senior' in any situation. Given Cain's length of service and his distinguished career, Cain very well may have 'outranked' many Commissars who held positions such as Captain/General-Commissar, and there are likely Lord-Commissars who would defer to Cain on reputation alone. The books also don't span Cain's entire career (Yet) - It seems more then possible that when Cain was brought out of retirement by the Black Crusade he claimed a Lord tag. I don't think they bring Hero's of the Imperium out of retirement to go slogging about at regimental level at almost 200 years old.
* The reason he keeps his Chainsword is the same reason he kept his Laspistol when he could have upgraded to a Hellpistol. The heavier weapons could throw off his balance and possibly get him killed in combat. Though, why he couldn't just practice with the slightly heavier weapons is never discussed.

[[WMG: One Per Three Thousand?]]
Is Cain really the only Commissar attached to the 597th? They have 3000 troops. In the games, you can have several commissars. In other books, Commissars are attached to companies (75-250 people, give or take a few hundred depending on future army organization works). Even if companies (or more likely, battalions) consisted of 500 men and women, each would need a Commissar. Wouldn't there be at least half a dozen Commissars attached to the Regiment? I don't remember any mention of other Commissars. Do you know how much paper work Cain (Jurgen) would have to fill out for that many people? Emperor knows how many disciplinary actions he would have to make with that many people. He could never get the job done alone.

[[WMG: Editing Errors or Emphasize]]
Occasionally there are sentences where the words have twice to thrice the amount of spaces between them. Is that editing errors or for emphasize? Also, in ''Caves of Ice'', Storm Trooper Sergeant Welard is referred to as Willard at one point in the memoirs (it wasn't spoken, but written in there). Every time he was mentioned, he was referred to as Welard (he didn't even have a second name or anything), so was this a mistake or was it his second name. (Are those name even pronounced the same?)

[[WMG: Gravalax]]
How did the Guard/Inquisition manage to purge Gravalax of genestealers without the population as a whole learning about the infestation. Even with most of the purestrains killed by Zyvan's men, along with the lion's share of the genestealers in the PDF, there still could be thousands scattered around the planet, and you can't perform mass genescans and purges without people realizing that you're doing mass genescans and purges. Despite this and the fact that the Guard and Inquisition would never leave a planet to be infiltrated by genestealers and later Tyranids if they could possibly help it, Gravalax's histories don't mention genestealer activity as part of the conflict with the Tau.

** What I don't get is why keep it a secret? I can understand Chaos - it deals in temptation, so the less is known about its schemes the less the chance some bored/ambitios/crasy/desperate bastards might decide to reenact them. I can even understand Necrons, seing how the only coherent thought the Mechanicus seem to have about them is "JustThinkOfThePotential". But Genestealers do not tempt or offer anything - they just infect people without their knowledge or consent. And there's literally nothing to gain from associating with them, not even the flimsy promises of Chaos gifts - you become a mindless puppet and then you get eaten. So why not have people be aware of them, and perform genetic screenings to root out the hybrids?

[[WMG: Sorel]]
How is it that the sniper from "For the Emperor", who throughout the story was very attentive and was able to notice small movement in darkness, was able to be snuck up upon by Governor Grice at the end, in bright daylight, while the others were standing around talking? It would seem he would have noticed Grice walk into the hallway, or if he was already in the hallway, they all should have noticed before hand.
* Given they had just emerged from a secret passage, it's far more likely that he ambushed them as they entered. Remember that, despite Grice's apparent idiocy, [[spoiler: he'd already demonstrated pretty impressive marksmanship and stealth skills (he shot two ambassadors in the middle of a diplomatic function and didn't blow his cover, even after being accused - albeit with Cain's unwitting help) and the information he got from his connection with the rest of the hivemind (combined with knowing the tunnels they were in) probably let him know where they'd end up.]] Besides, all four of them were walking and talking - it's possible Sorel was distracted too (maybe wondering what Cain and Vail were going to do with him now the mission was more or less over, just as Cain was), psychopath or not he was only human.
* In addition to the above comment, it's likely that Sorel didn't notice him '''''because''''' it was broad daylight. He'd just spent well over a day miles underground in poorly lit tunnels. Can you imagine how badly your eyes are going to hurt when you're suddenly exposed to bright light after that?

[[WMG: Genestealer scans]]
Given that the novels imply that the device that scans for Genestealer infection is portable and fairly fast, why don't they just install those scanners at all the entrances for spaceports and major government facilities like we do with metal detectors in RL? Even if it can't stop cults from forming entirely, it would slow the spread, keep people in power from being infected without being detected, and give an early warning that there are genestealers that need to be dealt with.
* Imperium is very very bad with most kinds of electronics. It will cost insane amount of money and resources. Another problem is the fact that you need to install and calibrate those things. And control them and read the results manually (see point 1). It was explicitly mentioned than if a world is infected, it means that Hivemind can control anyone. Unless screening is done by the IG regiments arrived from off-world and calibrated by techpriests that arrived with said regiments, there is absolutely no guarantee that the results of the screening can be trusted.
* In ''Duty Calls'', after the genestealer attempt to blow up the Darien spaceport, there's a reference to genescans now being required for travel between plateaus. So the tech's available to the Guard. Getting the Munitorum to authorize its usage could be tricky, though. Cain makes it clear that they're heavily into ObstructiveBureaucrat mode, and short of solid evidence (such as a Hero of the Imperium almost getting killed dealing with implanted pilots) releasing special equipment isn't gonna happen.

[[WMG:Kildhar's scans]]
It is specifically mentioned early in the book that Kildhar uses a genescanner "proving that she's herself"... yet Cain's big reveal is that she hasn't been detected by pre-augmetic genescans for three decades.
* She was probably nudged by the hive mind into installing a post-implantation scan into the scanner. If her "baseline" contained 'stealer genes, the machine wouldn't know any better -- it would just match the two sets and let her through.

[[WMG:Does Jurgen know he's a blank?]]
Something I was wondering about. Has Cain (or Amberley) ever actually taken the time to explain to Jurgen that he's a blank? I mean I would assume that they have but whenever they actively use his ability it's always at Cain's orders (charge the demon prince, get closer to the psykers). So it does make me wonder if Jurgen actually knows that he's a blank.
* Yes. Exactly when it happened is unclear but by the time of ''A Mug of Recaff'' it has been explained to him. Exactly how much of the explanation he understood is a little vague, but Jurgen is aware of it in a general sense.

[[WMG:The cover of ''The Greater Good'']]
Assuming that the covers for all the novels have been in-universe Imperial propaganda posters, it makes no sense for a Fire Warrior to feature in a "heroic" position. Officially, Imperial propaganda paints the Tau as untrustworthy enemies.
* Take a second look. Cain is moving forward, charging towards the enemy as a perfect specimen of mankind while standing above the Tau warrior. Meanwhile the Tau warrior is falling back, desperately firing at an enemy. Also notice how Tau is shown ''below'' Cain as a much weaker physically. In essence, while frail Tau is desperately retreating from the enemy, the human (Cain) is charging forward without fear.

[[WMG: Jurgen and the Astropath]]
Once Cain finds out that Jurgen's a blank, he's very careful to keep his aide away from any sanctioned psykers to prevent a Rakel-style reaction from blowing the secret. Except, that is, for the meeting in chapter 18 of ''The Last Ditch'' (right after everyone's learned that the planet has a tyranid problem). It's specified during that chapter that both the head astropath of Nusquam Fundamentibus and Jurgen are in the meeting room. Granted, the mention of Jurgen's presence has him near Cain, while the astropath is "at the far end of the table", but Rakel always wants a lot of distance between herself and Jurgen and astropaths in general are supposed to be powerful psykers. So why is the astropath not having a seizure? Is the meeting room really that large? Or did Cain name-drop Amberley before the meeting to convince the astropath to hide her/his reaction to a blank's presence?
* Jurgen's nullifying field has a range, which while never made explicit in feet or meters, can more or less be assumed to be 'smelling range' (his powers always seem to kick in the moment Cain smells him.) Furthermore, not all Blanks are equal, they have different levels of 'power' the same as a Psyker. In some cases, a Blank's touch can kill a psyker, while Jurgen's only causes pain, though admittedly a great deal of it. And considering the first time they met, he touched Rakel and hurt her as a result, and she isn't mentally stable in the best of circumstances, she likely avoids him because she associates him with pain.

[[WMG: Inquisitor Vekkman]]
Why did he just go off to the asteroid colonies without trying to question Cain? He saw the Commissar recognize a fairly powerful Slaaneshi daemon on sight and address it by its given name. As an Ordo Malleus Inquisitor, he should have been very curious about that. Even if he made a snap ruling that he wasn't secretly a heretic after Cain played a major part in banishing the daemon, at the very least he should have picked Cain's brain for every piece of information he could get about Emeli so that the Inquisition would have a file on her for use in any later encounters.
* Three possible explanations (if we assume that using the rod was enough to convince Vekkman that Cain couldn't have been a cultist):
** He spent a good chunk of the battle unconscious, so he might not have remembered that part (ATapOnTheHead is a lot more serious than people tend to think).
** It's implied that Amberly warmed up to him a bit. It's possible that she shared any information he might want from Cain.
** Cain did explain everything to him in the aftermath, but didn't include the debriefing like so many other details he leaves out.
* Additionally he mentions a familiarity with the events on Adumbria and Cain's involvement with that. So it's entirely possible that Cain's report to the Inquisition on that event already included all of the relevant information about Emeli.

[[WMG: Jurgen, take a bath!]]

*** Perhaps the natural aversion people have towards Blanks manifests as stench. The human brain knows there is something off about Jurgen, but cannot explain it, so it fires off the negative olfactory receptors as a warning.
*** In support of this theory, whenever Jurgen's odor is mentioned, it always seems to become noticeable at the exact same moment his Blank effect kicks in.
** In the Ravenor books, there's a Blank on the Inquisitor's team who is basically a pick-up artist and is constantly looking at nudie mags. People justify leaving him alone because he's an odious little toad, but they'd want to leave him alone anyway because he's a Blank. Every Blank develops a bad smell or poor grooming or horrible personal habits so that people want to leave them alone, as a manifestation of their soulless nature.

* Additionally he mentions a familiarity with the events on Adumbria and Cain's involvement with that. So it's entirely possible that Cain's report to the Inquisition on that event already included all of the relevant information about Emeli.

* Not a book, but Mitchell wrote a Vail [[http://www.blacklibrary.com/warhammer-40000/hidden-depths-ebook.html short story]].

*** Although given the general nature of the 40K universe it seems likely that most quartermasters skim a bit off the top and no one really cares unless they get too blatant about it. In fact Jurgen basically says as much in *The Smallest Detail* expressing surprise that the quartermaster thought he'd bother to report a bit of pilfering.

** Cain did explain everything to him in the aftermath, but didn't include the debriefing like so many other details he leaves out.
