Every time I go back to that map I find something else I love. This time I noticed that there's a cave (near the witches' herbs/dancing fairies) labeled "Laidley Worm" with a discouraged dragon sticking out of it. That's one of the story threads connected up with the person-turned-into-a-dragon family of ballads, chief being "Kemp Owyne": https://mainlynorfolk.info/frankie.armstrong/songs/kempowyne.html
