Yeah, I would probably port them over as warriors of the dragonborn or something, but we could develop them as on an island of their own. Would need to change the whole lore. Doesn't bother me.
I was going to add the kenra from Amonkhet as a subrace too - I was thinking they might be better, but they are warlike too.
Not being more warlike might be a reason she left. But yeah, I would have thought a canisaran shaman-type character would be better suited for healer ;)
But I am very open for players to shape the world, so to speak. I am writing up areas of Eledros right now based on PCs from other regions. The whole idea of spirit stones for that setting came from Dion's PC BG.
Anyway, if you just want to chat - feel free to hit me up on Dischord, now I know what I am doing ;)
