The land that appeared was once one, Pangaea, but it separated into islands we can continents, isolated from each other by the vast expanse of the ocean. Land people, isolated from one another, find strains on their unity as people.
Sea people are different.
The ocean breeds a unity in people from all lands who go to sea. The ocean selects a certain type of person from all of the races of humanity that come upon it. This type of person stays with the ocean. Sea people are simply those with understanding, passion, and commitment to the sea. All people, land or sea, work to live in harmony with nature.
