how about the relationship between seadwellers and landdwellers?
Did you know that clown paint is corrosive to seadweller skin? It's a closely guarded piece of knowledge! Some very nasty executions have been done this way.
I say this to set the tone of relations: strictly speaking the Ranking Highblood, leader of the clowns, is the highest in blood save the Empress, and the seadwellers Do Not Care for that Shit at ALL. The paint helps prevent any of them from trying to be the highblood and a seadweller both not that that's something any of them would want.
There's a real division between land and sea, the sea having it's own courts and the land being definitely separate and lower. It's not going to affect the life of anyone who isn't jade, Navy or higher, a clown, or Mindfang, though. Warmerbloods are also disdained by the high land dwellers so who is doing the oppressing is less important save for some teals who've really bought into the ideals of prestige (Philosophy tube' S video on the monarchy gives a good run down of that, that sense of belonging and commonality with someone without sharing your best interests)
Jades just Have respect. They do a hard job and they are vital for reproduction and theirs is a rare caste. They don't OUTRANK sea dwellers but they rarely MEET seadwellers.
A navyblooded cavalleader declared war on the sea once, before space perforce united all trolls, but like badly. Had the cavalreapers charge in. Some drowned. Seadwellers feeling obnoxious will bring it up.
