Questions and answers #5: Who's the boss?

As stated in this post, I am answering ten questions about Toby's world in preparation for the release of A Red-Rose Chain. Please note that these are questions about the world, not questions about individual people, things which have not yet happened in the series, or what is coming up in the books. I am still taking questions in the comments on the original post.

Our third question comes from seraangel, who asked...

"Do the air and fire kingdoms have their own royalty like the sea kingdom or are they beholden to whatever high king/queen rules in that section of the world?"

Yes. They have their own royalty.

Y'all, I really want to keep answering questions, but I'd say more than half the questions I have remaining are either a) spoilery ("Whatever happened to Bob?") or b) yes/no ("Is there a door?"). I really, really need more questions that will encourage elaborate answers. So please! Go! Ask!

(Note that this is not a slap at the remaining questions. But I need things I want to answer, can answer, and have the existing framework to answer. Please ask me questions on the original post.)
