Worldbuilding can be hard sometimes because I'm like hey how on earth do you decide and make a consistent perspective on family units when a household is both orientation neutral and has male/female harems due to wanting to have magic in the family as much as possible.
Like example: an Aurum man takes on an Argentum man as a spouse in his house. Now he wants the Argentum to have a child to either have more Argentum magic or to have a child with mixed magic. They both can't produce children so the Aurum man probably has to choose someone? What if that's outside the household? How is custody decided? Or is it going to be a woman in the harem, or a sibling to the Aurum man?
Making them orientation-neutral (as in they may all have their own individual orientations like straight, gay, bi, but they don't really care or discriminate and people may take on a same sex spouse for political or economic reasons if not sexual preference) definitely throws a wrench into an otherwise simple and rigid system.
