So old thread is old but is more than just a memory. So I decided to take the various maps I had put onto the Lunar Shadow Wiki and put them together:

As you can guess, it's unfinished and I'm still not sure if I've connected the maps correctly. Also the long section left of the Entrance represents the bad ending you can get at the start of the game.

Then I went back to this thread, made use of the colour coded maps Cibryll (aka Ariana/Yui Seymour) created for this thread and updated the map.
