I remember reading the comments below the Lord Commander Militant Ciaphas Cain omakes about how Terran nobles would react to Jurgen and his being both slovenly and a Blank. So here is that reaction...

Also, Crimelord!Cain, Sororitas!Cain, Lord-Commander-Militant!Cain, Penitent-Crusade!Cain, and all the other Cains of the Omakes. All of the above are worthy of continuation, and I hope they are continued and made into full works.
Also, the female version of the name Ciaphas is Caia.

"What is that stench!?"

Ferik Jurgen was a simple man.

He was unremarkable, really. The only thing that was notable was his hygiene, or lack thereof, and the fact that psykers and daemons tended to hate his very existence. Nobody really took note of him. He was just a loyal aide of the Lord Commander Militant, and that was all there was to take note of from history's perspective.

To be frank, Jurgen enjoyed this existence. He got to serve a Lord Commander Militant who happened to have saved his life once before, and who most certainly was a better man than he. Jurgen was compensated most generously, but he did not exist for money, he existed to serve. And who better to serve than Ciaphas Cain, who was the best man he knew.

Of course, all that musing came to an end once the tanna was brewed. The Commisar needs his tanna. Why the Lord Militant preferred that title, Jurgen had no idea, but he would ask Cain. It would be improper.

Cillian Feracci was an important man.

As one of the most senior aides to the Paternal Envoy, he was given the discreet task of spying on both the Envoy (who was of a weaker House of the Navis Nobilitite due to politics) and any potentially unfriendly Lords of Terra, including the other High Lords themselves. This was important to do, as all in the Navis Nobilite knew that should they cease to be useful, the Houses would be killed immediately. So, the Houses engaged in espionage and on occasion, assasination. A psychically changed mind here, a disappearance there, some potentially falsified incriminating documents scatter here and there... nothing too big, or too major. It helped that the Inquistition the Navis Nobilitite had an agreement and mutual understanding with eachother. The Inquisition would overlook the Navis Nobilitite and their schemes, and the Navis Nobilitite would provide off-the-books Navigators and ships for the Ordos' most secretive projects. Of course, there was a limit to the Ordos' charity, and the Houses have had to purge themselves of a Tzeentchian or Slanneshi cult once or twice...or more...

And so, information gathering was Cillian's job today, despite a few High Lords looking rather killable today.

As Cillian walked down the hallway to the offices of the High Lords with a stack of paperwork, he came across a most wonderful opportunity for subversion and espionage. He saw a slovenly Valhallan just sitting there brewing tanna! Cillian moved to rid the lowly soldier of his status and life for daring to trespass on Terra in his sub-human form, but the Valhallan turned and he saw the patch of the 597th Valhallan Regiment.

The Valhallan 597th Regiment. The former regiment of current Lord Commander Militant of the Astra Militarum, former Commissar, the Hero of the Imperium, Ciaphas Cain. This was Ferik Jurgen, most trusted aide of the Lord Commander Militant of the Astra Militarum. Cillian Feracci instantly knew that he had to somehow subvert Cain's office and find some blackmail. Cillian wanted to get rid of Jurgen, but that was impossible.

Ferik Jurgen had been by Cain's side throughout the former Commissar's entire military career, and was thus was trusted in a way few people on Terra were. Fortunately, Ferik Jurgen seemed to be simple enough to be just ripe for brainwashing. And ripe was the key word, by the Emperor did Ferik Jurgen stink! Cillian knew that he could not get rid of Ferik Jurgen, but he could recruit him as a spy. Better Ferik Jurgen than Amberley Vail, as if the House's touched even a hair on Vail's head, the Inquisition would come down on the Navigators and execute them all. Better a lowly soldier get his mind frakked up than try to decompile the mind of an Inquisitor, then.

As Cillian Feracci approached the Valhallan he felt more and more uneasy. The air around the sloven Ferik Jurgen felt... wrong, like the aide should not exist. The stench got stronger as he got closer, becoming a miasma of rotting sweat and disturbing silence, like the very presence of the man was anathema to existence. Cillian had heard rumors about these types of people, but they were rare, and most assuredly not a threat to a member of the Navis Nobilitite. He would just open his third eye as wide as he could and...

[Redacted by order of Lady Inquisitor Amberley Vail]

I can't frakking believe I am saying this, but I miss the days when I and the 597th Valhallan were at war.

For all the trouble that I managed to find myself in whilst trying not to get shot by my own charges, it was a simpler existence to what I my life had become as Lord Commander Militant(I frakking hate that title) of the Astra Militarum. As a regiment Commisar of the 597th, I was only really responsible for that one regiment, and the eyes of trillions of humans only knew of me through all the propaganda and lies that came from my attempts at both self-preservation and fleeing from whatever battle to happend to find myself in. While it was tiresome, it became predictable, and political decisions didn't really affect my role or my chances at survival all that much.

Being Lord-Militant means that you are always watching your back for people to betray you or to make an example of you, all for whatever goals of self-advancment or political games that the people of Terra are so intimately familiar with. It means that whatever friends you have are either from the days before your ascension to your position, are hard-won at best, or are subtly manipulating you through any available means.

How I had managed to become Lord-Militant, I had no idea, but that is a story for another time.

Today, I was dealing with an issue that deep down I knew was inevitable. Namely, my trusted aide Jurgen's malodourous hygiene and his deleterious effect on all things psychic or daemonic. This trait of Jurgen's existence has saved my hide on more than one occasion, but it was the cause of my current troubles, as a member of the extremely powerful House Feracci of the Navis Nobilitite had lost the services of one of its most genetically stable heirs, and my aide was to blame. Ferik Jurgen and Cillian Feracci were walking past eachother when Cillian's third eye opened wide and just...popped.

Thankfully, a few medicae were nearby and able to stop the blueblooded freak from bleeding out, but for the foreseeable future, Cillian Feracci was without his family's most valuable trait and abilities. So now the family of the most powerful Navigator House in the Imperium wants the head of my most trusted aide. Thankfully, I am in no immediate danger of dying, as I have a few things going for me. The Vahallan 597th chose to follow me to Terra, and have quartered near my offices and livong arrangements, so I have a loyal guard who are unlikely to betray me barring an extensive Genestealer infestation.

I have the support of the Inquisition through my ties to Amberley, and they will prevent the House's from engaging in forgery, blackmail, and the like. I also have managed to cultivate some goodwill amongst the Arbites when I and the Valhallan 597th helped root out a budding Genestealer cult underneath Terra, after I had discovered some infected Valhallan guardsmen after a party at a local nightclub, the entire incident proving valuable in ensuring that I am not the subject of a sham trial.
Of course, all of this did not help at the moment, as the patriarch of House Feracci was ranting at me about "purity" and "loyalty" and whatever words I could pick up from his droning speech.

Of course, this changed immediately, when the Inquisitorial representative showed up. I could not pick up his voice, at least until Jurgen showed up, the patriarch's eye exploded, and I rediscovered my hearing and self-preservation instincts through way of me drawing my trusty but decorated laspistol
The Inquisitorial representative shot the patriarch with what I presume was a stun round, after which he explained his findings from the investigation to me and the Provost Marshal.

Cillian Feracci had made the foolish mistake of trying to brainwashing a Blank, and the patriarch was doing something similar to me and Provost Marshall Darchmar in an attempt to protect his grandson. While both would live, they and House Feracci would be exiled from Terra until their House proves themselves worthy of serving the Imperium once more.

Specifically, they would be attached to the Lamentors.

After this, there were mentions of reforms, which got my hands twitching like an addict without his fix.

This was going to hurt me and add to my undeserved reputation, wasn't it?

Sarius Gorki was a busy man nowadays.

As the Paternoval Envoy, he was the representative of the Paternova, the Navis Nobilitite, and the Navigators, as well as a High Lord of Terra. He was only a representative, but he still feared for his life nowadays, as all Navigators were being looked upon with suspicion after what had recently happened.

Most of the Imperium has now heard what had happened to the Lord Commander Militant Ciapahas Cain, or at least what House Feracci had tried to make Hero Commissar into. A prominent Navigator house had tried to subvert first the Lord Militant's trusted aide Ferik Jurgen, and then tried to brainwash the Lord Militant himself, along with the Provost Marshall of the Adeptes Arbites. This plot was only stopped by way of the aide, who happened to be an heir of the Pariah Gene, anathema to the Navigator Gene. This has had many dire consequences for the Houses. Before Jurgen could be assaninated, he was made a hero by the Arbites and the Militarum, both of which have now become staunch allies of eachother. The Guard can now call upon Arbites support whenever there is suspicion of foul play or subversion, and the Guard is now regularly called upon by Arbites in need of heavier firepower than available to the Judges.

Additionally, it has since become fashionable for nobles, especially Lords of Terra, to have Blanks in their entourage, whether as aides, as bodyguards, or as butlers, all to prevent their minds from being tampered with. Even the Arbites have been recruiting Blanks, both as part of special squadrons and as part of regular patrols, all this in order to better combat the varied cultists and the now-infamous occasional rogue Navigators.

Pressure has been put upon the Lord Militant, Provost Marshal, and inquisitorial representative, but this new trend is here to stay.
Additionally, the Paternova, found to have endorsed the brainwashing along with other unmentionable, has been executed, and Gorki's new boss is now Uila Lamma, a rather controversial figure.

As her rival Kadak Mir was executed as well, she is now without rivals or challenges.
Gorki's position is secure, as he is the longest serving Enviy for a reason, but he now fears for the future.
