The Fool (spoilers for all RotE books, including LST)

[redchild]

and the second, in a world where women are held in higher reguard then men, the scholars would have disreguarded the fool. (i.e. Kettricken readily took place of the kingdom without unrest from the people after decades of male rulership, Ronica Vestrit being a lead bingtow figure, the women from the rainwild rooster family are the richest in their land, plus the rainwild showing emphasis for female recruits).

Not sure if the land the Fool was born and grew up in was matriarchal though. I don't recall a name either, only that it was to the south and east of the Six Duchies. I'll have to look it up. I suspect it was egalitarian, seeing as the scholars are so reverent of anyone who is born a White, it probably wouldn't make a difference to them if it was a male or female- only their legitimacy as a White Prophet matters.

The Mountain Kingdom and the Rain Wilds are both very egalitarian societies, and while Bingtown was once egalitarian, Chalcedean influence is changing both Bingtown and Jamaillia into becoming patriarchal. Ronica is probably of the last generation in Bingtown who grew up without that influence, and I don't think the Fool chose to be a woman in Bingtown by accident, either. It was probably easier for him to stay under the radar and gather intelligence as a woman than a man. It may also be a reason why he chose to remain androgynous during his time at Buckkeep as Shrewd's Fool, seeing as it wouldn't give him any advantage as a male or female, but remaining an enigma might have offered him more protection in court.

Speaking of Bingtown, wasn't the Fool living in Bingtown before he came to Buckkeep?
