The Kato area has a long, narrow coastline and considerable fishery resources. Despite the lack of a good deep-water port, people in this region had built a prosperous life through fishing even before the establishment of the Posya Confederation.
Due to its favorable climate and proximity to the Emerald Forest in the Antani District, the area was richly endowed with resources, making it a thriving trading region within the scope of human civilization on the Old Continent since ancient times.
It holds geographical advantage as its connection to the Ligurian Peninsula enabled the emergence of engineering technology while the Transia Barbarians were still struggling with cold weapons. Some factories in the Kato area were already utilizing the mechanical technology of the Half-body Man to create wealth.
Since the establishment of the Posya Confederation, the Kato area has been its money bag.
