Your application sort of gives me the impression you may not have read the history bit. Are you under the impression it was always islands? On top of that, what's the status of the intervening five-hundred years since the rains fell? I'm sure they wouldn't have gone back to the way things were, not exactly. There was a hundred years of devastation wrought by rising sea waters and the pressures brought by migration, though would have had drastically changed things.

Apart from some awkward spelling mistakes (emailing princes?) I don't see anything glaring to be honest.
