Where can I read more about the Iridian Fold disbanding?

[Ajaxius]

In Battlecry, Paizo included an archetype for the Iridian Choirmaster, belonging to the Iridian Choir, a splinter sect of the Iridian Fold.

The opening line introducing the archetype is, "When the Iridian Fold disbanded,..." However, giving a cursory flip through the book, I wasn't able to find any information about them being disbanded - why, how, or when.

Is there anywhere I can read more about this, or is this a lore-drop solely wrapped up in this one, single line that introduces the archetype?

I'm not 100 percent confident on this answer, but if the wiki is accurate, which isn't always the case, then the last time they were concretely mentioned was in Distant Shores in 1e during the Ular Kel section. So, yes, I think it's just a brief lore update/drop in Battlecry unless it's been mentioned elsewhere in a Society book.

Yeah, and Distant Shores was also where the Iridian Choir was first mentioned as a more progressive offshoot of the Fold's philosophy (namely in dismissing their belief that "shared heart, shared mind" couldn't be achieved by women as sexist nonsense).

Seems to be a little bit of a retcon too, since Distant Shores places the Choir's origins in Ular Kel alongside the Fold, but Battlecry! describes Kaer Maga as the center of their movement. Unless the implication is that the members of the Choir made a long pilgrimage to unite with the members of the Fold there.
