So, I had input in the Helayna art changes because I'm in the later stages of planning Helayna's arc update and finale.
The intent is that Jezera will still place the Rakshan ring on Helayna's finger. But, we wanted a signifier to more clearly and visually demonstrate the supernatural nature of the ring's effect on her. I mean hell, right now we frequently fail to even include the ring in art. But that question of "how much of Helayna's behaviour is her own will" and "how much is the influence of the ring?" so there should be more elements of that.
The way it will work is that at moments when the ring is having an especially pronounced influence on her, it will make her forehead glow with a Rakshan symbol. It's not a tattoo and isn't always persistent or actually etched into her skin.
