I know, but the point isn't that it's just intentional, but who named them. It had to have been someone cosmere aware, like Exalted Dungeon Master said, possibly the Heralds. Problem is that their language from back then hasn't survived, so it has to be a more modern term. Heralds are, of course, still around, so there's a good chance they kept it and passed it along, but are we sure?
