The Central Prefecture district was the capital of Baylands City, and in accordance, the centre of Baylands city-state. The name Central Prefecture was gotten from the fact that the district was located precisely at the centre of Baylands City. But it also has another background.
In the past, before the district system came to be, the original Baylands City was divided into prefectures. Later on, as the city began expanding its reach and influence, the district division system was used and the twenty districts were created. While the fifteen districts were made from the newly acquired land during Baylands City's expansion phase, the prefectures of the city were all restructured into the five major districts.
