(very) Loosely based off the three castes common amongst European renessiance societies, except they aren't really castes. Ideally they're meritocracies. This one represents the rough version of the Equatorial Federation of Schalltung only. The North and South believe(d) in this too, but in a very different way and also a lot more grim than most Equatorials do.
Here's to more Schalltung lore
_________________________________________
The black priest (Priester) symbolizes the spirit of the people
The white medic (Heilbringer, not the modern German word for a medic XD) the knowledge of the people
And the grey rider or soldier (Ritter, they say rider instead of knight, Söldner if it's meant as an insult) the strength and handymanship of the people.
It's a trinity cause of course rows of three are still seen in various societies touched by Christianity as fortunate, lucky and special. The trinity of God has kind of morphed into a belief in your own people as the world moved towards rationalism and material essentialism in the Dark Age of Technology. Thus the father being the medic, the son being the rider and the holy spirit being the priest. This has been the most pronounced within what was Jermani-descendant societies from all around the galaxy. So much, that this belief spawned psychic powers on its own and this very knowledge needed a whole planet to get stored in, thus, all-temperate Schalltung near the Solar System was chosen to relieve every Jermani descent society ofr their records so that they may get rigorously archived.

(little did they nor any surviving Jermani successors know that they're especially susceptible towards psychic influence and that their shielding seems to be weaker than from Non Jermani cultures, especially when they're more invested in learning about their ancestral history.)

The People's Trinity often gets translated into various games, including a mix of chess and monopoly (i forgot how that game with the houses and tge four colors is called, here it's called Mensch-ärgere-dich-nicht), various extremely simplified tabletop games (as there's only three types and you're the ruler) and even a rock-paper-scissors variation.
It's rather common for the pride of someone working a 'white' job to hold your index finger up high - you've just got all the knowledge needed at your fingertip.
'Grey' workers often pump their fists in the air or do so whilst holding a representative tpol of their respective craft. Ie. a sword for a knight, a hammer or a saw for a carpenter etc.
'Black' workers put the flat palms of their hands together and either hold them high or hoist them up over and over again.
They do this as a sign of pride when they did something outstanding that will usually help the entire trinity of people and of course to roughly identify themselves.

Grey workers include: handymen, construction workers, janitors, suppliers and deliverers of goods, soldiers, majority of psykers within,
White workers include: scientists, architects, professors, storage staff, archivists (for non moralizing records), a smaller contingent of psykers,
Black workers include: Caretakers, medical staff up to the chief doctor, orators, coaches, therapists, poets and writers, archivists (for moralizing records),

Imagine being so goddamn racist that after you realized that your breed of ultra 'aryan' psykers turn out to be mentally unstable, you immediately force your entire population to seed every single baby with red and black hair dominant genes because you want to mark the ultrablond hair, what you originally strived for as the mark or the degenerate insult to the teutonic way.
And then your home gets wrecked by these powerful beings and your people need to flee northwards
But you're still so racist you try and exterminate all that didn't seem in your stereotype stereotype teutonic way, including phenotype ofc.
Starting your racist little crusade against those of the equator very prematurely while STILL being all sorts of tortured, controled n killed by your own creations
Getting your ass beat n cornered by the our resourced equator banding together for once to stop this weird ass force.
And then having your people banished into the north pole along with some of the blond ones creations of yours
And then you start to rely on those you consider failures for manpower and durability
Making those slaves you once held as the paragon of humanity. Still deluding yourself in having the attempt of a single perfect form of man just in your reach, while you throw the corpses of your further failures to those 'blond ones'.
Knowing that brutal history should not be a taboo theme to make it more bearable, like the equatorials do, but an attest of bravery, strength and measurement of physical superiority. Of course, the spiritual one is always yours, for the ancestors talk of war and of purity and of salvation, and who are you to deny their bellows for the spread of their truth?
You are a slave to these icy, unforgiving terrains you and your people call home with a grim pride. You are a slave to your peers who are equally just one suggestion away from losing their minds, and the less disturbed one's brutal punishments for those malfunctions. And you are a slave to those you call ancestors. They are lying. They are saying the truth. They say anything to get you and your people to take over the mass population of this planet, and you believe they will help you make a paradise. Did it help the last time? The last time your home was turned into a tainted paraody of your arrogant dreams. This time? You may enforce your beliefs to destroy you for good.
I have a blond one OC now and his name is Widukind. These poor bastards usually don't even have names, but rather roles and numbers.
For a reason his hordetamer (a petty criminal sentenced to have to lead them) didn't quite do the job when Rogals Fleet liberated Schalltung and pulled it into the Imperial fold. So.. despite being a transluscent, 2 m mf with magenta eyes and muscle outgrowth in quite a few places, he somehow got in the Phalanx. His kind are being put to work as heavy loaders and are a lot better at surviving their work than their genetically untouched coworkers. Some do ask if they can eat their flesh when diseased as they require a lot more flesh. At first, they were highly hated for it but when they see the small altars of rememberance, having them light up when someone dares to ask, they start to treat them more like... weird looking pets. Look, they're basically abhumans so the tolerance is limited but on the Phalanx they can at least serve Humanity at large, and they're good at it.
Widukind however escaped, and he escaped into a forest that grows within the massive battle-barge, hunting down the animals living there and trying to lure people into the forest to finally, finally make them kill him. His impulsive and violently responsive conditioning (he was specifically raised to be a storm warrior) made it impossible for him to not keep throwing hands, mostly at his fellow blond ones.
He's depressive in a way that only rage (or someone who shows that they want him to be alive) can quell. Again, mostly letting this out on the various grox like creatures, ripping into them while they're still alive.
He soon becomes a sort of myth, as the forest is too vast to monitor each metre of ground with, but people will be lured by him.
