Hi guys - thanks for the replies, very useful and interesting.
The reference about Orlanthi sexuality comes from S:KoH page 29:
'Compared to many Gloranthan cultures, the Orlanthi have relatively few sexual taboos. They prohibit sex with people who have not been initiated as adults; with married people; with members of their own clan; and with not-people such as foreigners, Elder Races, animals, rocks, and the dead. Even those few taboos may not apply to members of certain cults or during certain religious rituals.'
So the picture I'm getting here is that basically all of the clan women that get married will basically leave the clan and join their husbands clan. Which means that basically all of the mothers in a clan will come from a different clan. I'm trying to imagine what that will be like - the network of social connections where this happens will weave clans together much more closely than a model where members predominantly married within the clan. Basically a woman will grow up in one clan culture, forming relationships there and living/worshiping myths/ancestors within that environment, but adulthood, motherhood and beyond will be in a different one, with a different (albeit related) tradition.
Related to this I was wondering whether most marriages tend to be arranged by the clan or formed through personal connection/feeling. I'm imaging that the former is the case, although with women having strong gender equality how this would work out in practice?
In response to AJS I was wondering what source you had for women of Ernalda being able to control their fertility - that's a major social advantage for women and frees them in many ways from being locked into certain roles in society. Is that the case throughout Glorantha or is that a peculiarity of Ernalda followers?
I have quite a few follow-up questions as often I find one answer leads to several questions, but I'll lay them out gradually and hope that your enthusiasm and patience endures.
Best wishes
