I don't think it's productive to go on a massive tangent of Kinu rants lasting for pages once more, seeing as we did it like 2 times already. Everything to be said has pretty much been said.
That said I'll repeat that incest content kinda creeps me out to begin with so not having that isn't what bugs me, but the entire novel writing nature surrounding kinu with the dumbass flashbacks, terrible writing and her would be spouse is just fucking ew. Now we get a quest too. Wow.
Plus, Kinu's whole "I grew up and fuck you dad" and her sheer antagonism just seems to be borne of that hellspawn debacle, which makes no sense to me. Why punish the majority of your players with a character whose existence is to bitch, because a minority wanted something?
