Yes, you spotted it. The locations are scanned biro sketches and the connecting lines are 3 pixel gimp lines. The idea is that the areas in between are less well known and therefore lightly sketched in by the cartographer. It's definitely unknown territory , though the players don't necessarily know this. However that doens't excuse sloppy penmanship! It would be better if they were just lighter, sketchier pen lines. I'll have a go and see if I can get a better effect.

Thanks for pulling me up on that
