The most we get is a line that basically reads as "please excuse our lack of male Moonkeeper characters in ARR." Also, notably, delivered from the perspective of one very opinionated woman, keeping with Koji's overall philosophy that characters only express their own understanding of things. I do concede that it's not literally nothing.

The men of the Keepers of the Moon live a wanderer's life, for they are at their best in small doses. Women and children keep the hearth, ply various trades, and accept game and visits from the menfolk.

But King Poach denies women this gods-given rule over matters of family. He forces women to live with him, forbids them to see their sisters, mothers, aunts. Most unnaturally, they lie with him and him alone!
Though I do appreciate the casual jab at monogamy.
