Tattoos
What if the angaran tattoos are the sign of their strong belief? For example, Jaal said that his true mother Sahuna is a firm believer and when we met her she has tattoos on her face. And a priest on Havarl has tattoos
There are not so many examples I have but I can say a little about Jaal's siblings - Baranjj, Teviint, and Lathoul - they said they joined the Roekaar because of their family which they're going to protect no matter what. And as I understand, the main thing of their religion is a family so I think they can be called believers. The same for Akksul
