Every time I read about this, I just imagine some creative person with the right resources decided to dip into the fantasy genre and do world-building. I’d do similar things as a kid. I made up all kinds of fictional things and made little encyclopedias for them. It is great fun

I just bought a book of this as a birthday present for my wife thanks to this post! (she already owns the Codex Seraphinianus, so it’s a sure bet)
