Nora K. Jemisin has been putting up posts on the characters and backstory bits to her novel, The Hundred Thousand Kingdoms. She just put up some info on Darre, which is an interesting look at a matriarchy.
She remarked awhile ago, how many readers bought into enslaving gods without a problem, but the idea of a matriarchial society was “fantasy” to them.
Anyway, it’s got a lot of interesting ideas if you’re looking at including a women-warrior society in your gaming (Artesia, Reign, for example).
I could totally see some fun Burning Wheel games working that way, especially since motherhood gives you a higher status as a warrior in Darre culture- (+10 Resources, maybe? Definitely a +1D Affiliation with Mother-warriors). Not only that, motherhood in Burning Wheel earns you an extra point of Steel, which is damn useful for warriors!
I could see a bunch of interesting scenarios built around clans doing raids and counter-raids for husbands, folks who’ve mis-used runes and left themselves sterile, and general bad ass clan warfare.
