Not only that but it makes me wonder if there is a deeper story behind what we've heard. All we know is that they're bad and beast tribes summon them. But everything has an origin, right? Maybe those rings/earrings are hints at what made the primals so angry in the first place.
So great find and thank you for telling us. I wonder what the lore thread people would make of this. After all SE isn't known for just putting in these random extreme details if they didn't have some point.
