Honestly I don’t get the slave thing at all, the way in which they become slaves or their redemption seems abit forced.
So descendants of someone who betrayed the goddess are cursed slaves, but if they work for 5 years their crest disappears and they’re free.
So from birth?
I guess both free and cursed slave descendants auto get cursed?
Why are they caged?
I prefer the usual, forced into it due to poverty, capture or for being a criminal. Clearly defined.
