What is the one thing about your world that people in the real world would find interesting?

It can be something that you've posted about before, or something you haven't; religion, languages, politics people, animals, plants, food, etc. Anything so long as it's one from your world.<br><br>This is a repost from a few months ago since I think it's an interesting question people here would have an opinion on.<br><br>I'll go first; in my world, the birds’ migration is powered by a magical ritual in the sky. I've written a separate post about this, which was well received, so I assume this is the one thing about my world that people in the real world would find interesting.
