J.R.R. Tolkien and Ursula LeGuin are only two of the legions of sci. fi. &amp;/or fantasy authors to map their worlds. When I saw the &quot;X marks the spot&quot; map of Treasure Island as a child, I quickly created my own world.  I haven&#x27;t stopped, but now software can create the world I want. The author is totally in charge of how the world looks and runs, but needs the ability to get an audience hooked as I was by Treasure Island.  This map is from a free map making site. torteyrnas.jpg
