Now we have reached the good stuff, this is how you generate characters, starting them as a young child and gaming their growth. This may be the only game system that you can run an Andre Norton YA novel as an adventure without changing the rules.
Where are you living, name, sex, lineage, clan, family members, wealth. Now the character is born. First ten years. What I do, accumulating skills. Barker is assuming upper class characters. Growing pains ages 11-15.
Optional 15-20 and 20+ a chance at injury or monetary loss but no real danger.
You now have a playable character you can use in a game or you can run them through the solo adventures adventures in the next three books.
Barker has a rant on how for humans there are only two genders. I suspect that a world that has TWO goddesses dedicated to sex and hedonism and the concept of Aradni, women who have petitioned to be treated like a man, might have many more than just two genders.
