It seems like the real idea of the game disappeared. I didnt know there where goin to be a ocean?
And as Bonez says, the ocean would be over with dots everywhere so the next island would be about 10 meters away from your dock?!
But if you think like this; there will be thousands of dimensions where the islands placed. So for example, there were goin to be a teleport in the Stone Labyrint, so if you walk through that you get to your guilds\' island. Or if he guild has a HQ somewhere in town you could go there, and there be a teleport there.
Of course it would be kinda complicated, but it would work wiht the basic idea from Xalthar.
