Beyond The Thousand Isles to the west is rumored to be a vast tropical continent watered by giant rivers called “Great Mbo”. The human natives are black as night, the culture is highly sophisticated and advanced but extremely isolationist.
The God King who rules over them from his great pyramid only allows foreigners in one island city, Bawaaba Mbo., so the natives of The Thousand Isles know little for certain of the rest of the vast continent.
