Just what it says on the tin. Most maps show the "terrain" you will have to pass to get to the icons. I just wanted to know which way to head so I didn't go off on complete wild goose chases, so I made this. The bottle in the center is the starting point. Beyond that, figuring out which icon is which is up to you (I was serious about the minimal spoilers).

I am not playing PC as much recently, so there will likely be a delay after map updates before a new version of this comes out, but I am not planning to abandon it.
