SPOILERS FOR RUBENS ENDING
Curious and this is (mainly) worded as a non-serious question, but I played as cis-male and at the end they have children. Is m-preg cannon in this universe, because it is implied that they didn't use a surrogate. Also I don't know if the child of Mauve and Okti are adopted. Can same sex couples just have children? I just find it interesting.
SPOILERS
Same sex couples can have biological children by ritual. If both are cis men or one of the couple can't give birth for other reasons, then they'd need a surrogate. In case of Ruben and cis male MC Mauve is the surrogate mother. I think I read it either in previous replies or on author's blog, though it's not mentioned in the epilogue.
