But wouldn't that be a fail? There are 6 immortals in the house, 7th can't have a child until their sibling dies and by that time 7th gen also risks dying?
@Nettlejuice Sorry for being unclear--I didn't mean to cause confusion about the 6th generation heir question. I just meant to say that if there's just one spot left but someone dies before childbirth, leaving two spots open, the mother may give birth to twins.
in my Immortal Dynasty, this happened to my third-generation heir who gave birth to twins. That didn't destroy my dynasty but made things harder because I no longer could add that pollinator I was anticipating.
