Musings on Custodes: Nobilitas Terra

Ah, the now famous “all Custodians begin their lives as the infant sons of the noble houses of Terra” line from the 8th edition codex (not reproduced in the 9th one, btw). It has now experienced the kind meteoric rise in quotation previously enjoyed only by biblical verses in times of major church schisms. Let’s talk about the part of it that’s actually interesting though.

So Custodians are drawn from the children of Terra’s nobility. It is apparently not exclusive and other sources are allowed on Custodes’ own discretion, but this is both the traditional and the main one. It seems that originally the Emperor was doing something of a mamluk/janissaries thing with them, taking infant children from the families of his potential rivals as both hostages and soldiers that could be raised loyal only to him. Later, when his power grew to so far outstrip that of Terra’s aristocracy as to make any internal challenge of it inconceivable, it instead became prestigious to submit a child of a family to this service - not conscription, but an offering to the golden idol of humanity.

So surely, in 42nd millennium, with the Emperor’s eclipsing presence… changed, if not gone, there must be some sort of interesting dynamic between the Custodians and the bloodlines that spawned them? Well, the codex seems to dismiss the idea out of hand, stating that there is no real way for nobles of Terra to recognize their scions once they become Custodians - which presumably means that there is no grounds for interaction? And sure, I can recognize why the official lore in its current state isn't interested in that: Custodians are fixated on the Emperor to the exclusion of everything else, and the Terran nobility itself is a fairly faceless thing in the lore, one of which we don't really know enough about to build any kind of investment from their perspective.

But here we are all about the things that could yet be, rather than the things that just are! And I honestly think a bit of lore expansion in this direction could be pretty interesting!

Between the origins of the Rogue Traders and the Custodians themselves it seems that, much like the priesthood of Mars, some clans on Terra were indeed once powerful enough to make the newly ascendant Emperor deal with them in terms other than total subjugation or destruction. Would the meteoric rise of the Imperium during the Great Crusade grow or diminish their powers? On one hand - the previously mentioned growth of the Emperor's power in relation to them and the whole new "breed" of imperial elite he was literally creating (I know that in modern lore there is some speculation about what were actually his plans for the Astartes and the primarchs post-Crusade, but however things would have turned out for them, had he his way, I doubt it would have resulted in even a modicum of power returning to the hands of his once-rivals)... But on the other - during times of obscene growth and expansion rich and powerful tend to grow even more so, and I doubt that grimdark future avoids this tendency. So I will go out on a limb a little and say that while during the rise of the Imperium the power of Terran nobility may have waned in relative terms, it probably grew in the absolute ones.

And the following ten thousand years of sitting at the top of a stupidly expansive feudal confederacy probably did not hurt them either!

In the days of the Era Indomitus, then, these vague "noble houses of Terra" must be some sort of force to be reckoned with - politically, culturally, and probably even militarily. Likely on a galactic scale. And the personal guard of the Emperor, the supposedly most advanced beings in the entire Imperium, the living symbol of his power - are staffed almost exclusively by the scions of those houses. Do you see my vision? Do you agree that something simply must be there?!

Custodians are the Emperor's representatives and envoys, the single most powerful military force on Terra and the organization in full undisputed control of access to the most holy site in the entire Imperium, a place from which, technically, ALL authority within its borders is derived. Even without the bloodline connection there should be some kind of a relationship between them and the other powers of the throneworld! Even if we look at the pre-codex, fully palace-bound version of Custodes that care for absolutely nothing other than the Emperor's corpse physical safety - they still recognized that the events on larger Terra influence this safety and need to be at least reacted upon. And in the modern version they have never even been that shut-off. Even before the lifting of the Edict of Restraint, Solar Watch patrolled the Sol system entire, Aquilan Shield departed on their mysterious protector missions and the Emissaries Imperatus were busy being a diplomatic corps, for fuck's sake. I find it hard to believe that they would simply ignore Terra's political players, leaving them to do whatever unless someone rolled up armed to the Imperial Palace. So there definitely would be interactions - and once that hook is in, the fun begins.

Are custodians willing to "stoop down" and play nobility's games with them? Do they even have aversion to doing so? Surely, with all the talk about their talents beyond head-chopping, they are capable of scheming with the best of them? And if doing so is the most efficient way to get the job done - why would they object? And if they are no strangers to political manipulation and the noble families desperately want the prestige that comes with having produced a Custodian - why wouldn't the demigods indulge them and use it as a tool? Especially since they - if we keep the codex idea of it being impossible to recognize surrendered infants as the Custodians they become - hold all the cards and can basically present any of their number as a scion of this or that family? And while we are at it - do they themselves actually know? I imagine it must be not that important to them, but are there any records kept? Could you be a 200 hundred year old Custodian fresh out of training (a random example - like so many things, it is not known how long the creation and training of a Custodian takes) and be suddenly told that the aging matron of a noble house with whom you have to go and negotiate is actually your biological mother? Would that stir something? Curiosity, at least? Or is the Emperor’s light so absolute that it can blind one to even the most deep-nested human impulses?

Do Custodians remember sins and glories forgotten by the tapestries of gold and jewels? Do they watch some relatively minor and unimportant house with baffling prejudice - all because someone from it almost outdid the Emperor in something more than ten thousand years ago? Do some bloodlines enjoy unseen protection due to secret deals that have passed out of all human memory?

What about the internal politics of the organization? Millenia of drafting from a relatively closed pool of families means that some Custodians are related to each other - does that matter to them in any way? Even if the golden demigods are completely free of prejudice and superstition - which their history of paranoia kinda tells me they are not - genetics do play an objectively huge part in their existence. Is more expected of those drafted from families that produce more Custodians than others, or have spawned some especially renowned heroes? Once again - is it even public knowledge amidst the Custodes?

And what about the nobles themselves? Do they seek favor of the Adeptus Custodes? Is such a thing even possible? Do they view them as another player in their political games, or are they more of a force of nature, a condition that everyone has to deal with and adapt to? How does the process of submitting children even work nowadays? Is it compulsory? How many are taken from each family/genertaion? Do any struggle against this harvest, or has the honor of the thing completely overshadowed any resentment that they might have had?

Basically what I am saying is that, for the purposes of worldbuilding, interaction between systems is always better than the lack of thereof. And if one were looking for the ways to expand Custodes' lore - this one feels like a great source of characterization for them.
