Throughout the revisions, you know that  I’ve been changing the map here and there.  Well, here’s the newest version of the world map.  As you can see, the detached village in the Demon Realm is now known as Ruby.  Amethyst, another human village, is now southeast of Opal, on what was once a peninsula, now a full-fledged island.

EDIT – Recently I’ve been saying “Crystal” instead of “Diamond.”  I assure you, it’s supposed to be “Diamond.”
