Why settle for just one? You could have a cat wife, a kitsune wife, a minotaur spouse, dogboy husband, orc wife, dullahan wife, elf wife and three catgirls are live-in maids.
That's why I qualified it as an option and not a requirement, of course plenty of people are going to want their entire harem. But the problem then is that no writing team on earth could possibly account for every single possible permutation of said harem, so it would probably end up as a generic ending with a bunch of if-else statements checking for individual members. I'm talking about stuff that couldn't reasonably be added to the game, like settling down as the patriarch of the Otomo clan and working as an ambassador to The Old Country, or becoming King of the Winter City and ruling over it with Ryn for the next thousand years.
I wanna know what a protenal Nareva gothmander tf would look like maybe perhaps a black scaled with blue fire or shadow like fire ohhh I really wanna know (and I really want a black scaled salamander now)
