also, in addition to what i said earlier, there is position of women in society.
arranged marriage + produced heirs to secure property may occur, but after that, the man + woman need not see each other again.
which means the existence of Mancubines. Because the alternative of chastity for teh next few decades doesn't make sense, since Amarr women have status. Or lesbians.
And a consequence of that, will be significant numbers of half-amarr children, because some women would want to have a child by their mancubine. 1% of a billion is still a large number.
And, what then would those children do? if the mancubine is a slave, then the child would not have any status at all, which I think the women would have a problem with. A noble woman's children with her husband would be her heirs, the ones with her mancubine must have some status, cannot be mere property for her heirs to dispose of if they feel like it.
So, the children have to be commoners, at least. Which would mean I think the mancubines also have to be commoners?
