The layout is an uncomfortable mix: it's information-dense, but it's not actually useful for getting around. Nothing on this map tells you where a particular Linking Book is in an Age -- only that there is one. So unless you're familiar with the game, the map is no good to you.
If you are familiar with the game, the map should be all sorts of fun. I tried to make everything as intuitive and recognizable as I could. Figure out what it all means!
