So I'm trying to add in a new civilization (Trolls/Uz from Glorantha, if anybody here is familiar with the setting)
One 'feature' of this race is that they've been cursed, so that some children are born as the stunted and pitiful trollkin, instead of being born as normal dark trolls. Trollkin are treated more like beasts of burden than people, they're of such a lesser class that they're not even quite considered a part of society anymore. So I want to occasionally have trollkin be born, but not to end up in leadership positions and such.
I'm trying to figure out how I want to best implement this. I thought about making them part of the caste for the generalized 'Uz' creature, but that would mean trollkin can end up producing dark trolls (or even Uzuz), which isn't quite what I want.
I could try making them another creature entirely, but then I'd have to figure out how to make uzko produce trollkin sometimes. I'm wondering if maybe I give uzko a syndrome they get on birth, that 'activates' at around the same time they'd reach child age, that has a chance of turning them into a trollkin? I'm not too familiar with syndromes, so I don't know how well it would work. If I do make them another creature, I'd need to make sure that they are still a part of the civilization entity too. How do entity raws react when you add multiple creatures to them?
