Something very interesting to me is just how family-oriented Abby is. For him/his culture, large families are celebrated. I've compared it to a wolf pack before -- the starting point tends to be a mated pair (or sometimes polycule) and their children.
Over time though, sometimes these families practically turn into villages. Being functionally immortal means that it's not uncommon to see much older siblings (50+ years old) still hanging around with the younger children. And while yes, eventually many of them do leave, it's also normal for these "dispersed" adults to eventually return with a mate/mates of their own.
So, particularly old and successful clans may consist of the original founders, dozens of children of varying ages, adult offspring and their mates, and even more children from them (grandchildren of the OG founders). Occasionally even great-grandchildren, though he says around that time most will strike off to start a clan of their own or join a smaller one out of sheer practicality (even the most successful would struggle to keep enough space + resources for so many generations of immortal beings).
As someone who isn't really close with my physical family, the idea of this just blows my mind.
