This sounds fascinating!

And beautiful. And, so far, completely comprehensible to Thor. Sure, he hasn't met some of these creatures, but he knows what they are, and this is the sort of world structure that fits right into his mental framework.

He listens with interest. It's clearly visible on his face, at least if Luna can read humanoid facial expressions; Thor's face is expressive, and there's no conflict here between courtesy and his feelings.
