Didn't have room in the subject, so kinks and warnings for this prompt are; sexual slavery, dub-con/non-con, mpreg, brainwashing
Seadwellers with purple streaks are capable of laying eggs fertilised by another troll, but this time it's a world with a reversed hemospectrum.
Breeders are the only sea trolls considered worth anything - tyrians are just another shade of purple trash. And their only value lies in their fertility. They're trained to obey any troll who comes inside them while they aren't in heat and guarded jealously.
Sea trolls are still the longest lived, so they're passed from noble to noble - not to their own offspring, but traded between lines and houses. The ownership transfer is highly sexual, and very degrading to the breeder in question. Dualscar/Eridan considers himself lucky to belong to the Scarlet Emperor, at least for now.
Either there's always a Scarlet Emperor/Empress, because (s)he has access to a harem of breeders, with one added by each Emperor/Empress and they're inherited by each ruler, or the Scarlet Emperor is a semi-mythological figure, who only appears maybe once in a thousand or more sweeps and is a harbringer of change.
