So let's follow through on what Square-Enix has given us about the Hrothgar, shall we? Whether or not the development team has thought about the implications or not:
- Male Hrothgar are far more common than female Hrothgar.
- Female Hrothgar are said to have a natural disposition for leadership.
So from this, we can infer a few things. (fair warning: some queer shitposting past the cut.)
First, if females are "relatively few in number" then in order for the population to not dwindle they need a high birthrate. If the hrothgals don't spend all their time pregnant, that implies that hrothgar have litters. Congrats, Hrothgar players! You have a bunch of siblings!
Second, the gender mismatch strongly suggests polyamory in the form of one woman with a harem of husbands/consorts is going to be a common situation; siblings from the same litter might well have different fathers, which can happen with cats.
Third, the gender mismatch combined with the Disposition for Leadership also strongly implies that child-rearing duties fall to the men in the family, so Hrothgar lads are gonna be the proud papas toting a kid or two around when the litter gets born, probably the ones that they're going to be directly responsible for seeing to adulthood with the family. Hrothgals probably raise their daughters directly, as a matrilineal process.
Fourth, this implies that the overwhelming majority of direct monogamous pairings among Hrothgar will be completely homosexual, and could suggest that many Hrothgar are bisexual! Good for them, really, they deserve the intimacy.
Last, I would like to call SE out for being absolute cowards in setting up all these implications and only giving Hrothgals the human-standard pair of boobs, and am choosing to believe this indicates that when given the right pheromonal signals that Hrothgar men will lactate for their kittens. How else are they gonna feed that hungry litter?
(Edit: No wonder Hrothgar players have tended to be wholesome in a weird way, right?)
