I dont know what any of those things are Simas
I'm pretty sure the Dunyain didn't have much of a long history before Ishual. They were a minor philosophical cult without a huge number of followers. I could swear we get a few brief mentions of them in WLW... Wherever it was, I got the feeling that they were not some secret society that stretched way back, but more like a new extremist group that cropped up soon before the Apocalypse.
