Crescent Island.
One of the large overseas islands.
It was located in the southern part of the Eastern Sea and had a permanent population of about a million people.
These people were all descendants of people who had migrated from land over countless years for various reasons.
The residents of the overseas islands were basically from land, a small portion from the Western Continent and most from the Eastern Continent.
Today, they had already become natives of the various islands.
Due to geography, Crescent Island happened to be stuck at the intersection between the Eastern, Southern, and the high seas with three ocean currents flowing through it. As such, there was frequent population movement and it was one of the two most prosperous islands overseas.
It was named Crescent Island because the overall shape of the island resembled a crescent moon.
