Chaos Island lay at the very center of the Chaotic Star Sea, surrounded by 4,800 islands, perfectly divided among the four races, each controlling 1,200 islands.

Chaos Island served as the main headquarters for the Humans. To the north, several hundred miles away, lay a sea region known as the Devil Sea, a notorious death trap within the Chaotic Star Sea.

To the west of the Devil Sea was a large island called Barbarian Island, the headquarters of the Barbarians.

To the north of the Devil Sea was another large island named Demon Island, the headquarters of the Demons.
