When you think about Eurmal’s cultists, a good source of inspiration are the sacred clowns of the Pueblo Indians:
So pretty much every clan has a half-dozen or so “clowns”. They gather for big religious ceremonies of the Lightbringers and cause trouble, mocking the rites, making fun of leaders, etc. But they are PART of the rites and important magic. So their activities are protected strongly by the Orlanth cult.
Are they regular members of society outside of the rituals? No. They are like shamans.
