But he didn't want to do that. While Roland could directly make the entire Subcontinent into his Kingdom, he didn't see the need anymore. Most of his resources were mined at the seabed of the ocean and he didn't need a workforce because of his Bots. So he decided to vassalize the remaining 80% of the Subcontinent, they could remain as independent Duchies and Kingdoms, but they had to listen to his commands first. It would spare him a lot of trouble.
