Here's the latest version of my 6 Islands campaign setting. I'm leaning towards the humans that live on the island possessing a culture and technology somewhat like England just prior to the Norman Conquest. Among other things, doing so would reduce the importance of horses. I've never had a whole lot of empathy for horses and I have almost always imagined fantasy rpg parties as walking rather than riding. If they are riding, it's almost always been either by ship or on the back of fantastic creatures.

The light bluish-green areas are shallows. I'm not exactly sure about the brownish island. It's basically a coloring error I left in because it gave me something to think about. Maybe the land on that island is less wooded or less fertile.

The scale of the map is probably about thirty six miles to a hex. Bigger then a breadbox, but smaller than most settings.
