First, are we just going to refer to the new High-blood as Whomst? Second, I doubt we'll get a Violet blood, just going off of the shape of the silhouettes' horns, because they seem like jade bloods. Which is something that I was wondering about: the Jade bloods. They're supposed to be rare, which I think was bothering some people, but we don't know what the setting of Act 2 is yet. There's probably a reason why there are more high bloods than low bloods that we don't know.
6 of a caste, at most, is not big enough of a sample size to say like, “more or less rare” on Alternia, so it’s not like any pattern or canon is broken by having like, 7 Jades. It just seems we’re in the continent? Act 3 may happen closer to the coast, or in one of the underwater cities, where there are more Seadwellers.
Also yes I’m gonna call them Whomst for now.
