The planning scheme for the six new towns went through continuous revisions and was eventually confirmed and passed by Liszt. According to this plan, the future administrative division of Black Horse Island was already clearly defined.
The southernmost town was the port town, adjacent to Black Horse Port, and it was set to be upgraded into a port city, serving as the central city on Black Horse Island, with Liszt's new castle situated on the outskirts of the city. This city would concentrate most of the territory's industries, becoming a modern industrial city.
The most northwestern town was New Harbor Town, neighboring the yet-to-be-developed New Harbor, and also had the potential to be upgraded into a city. It would serve as the starting point for Liszt's exploration of the Sea of Azure Waves and the Devil's Sea.
