After Minos received members of some of the major races of the Continent of Beast in his capital, a whole year passed, and his agreements with the Phoenixes, Mammoths, and Dragons were confirmed.
During this time, he had also reached similar agreements with the Marine Empire, which had sent a group of representatives to negotiate with him months after his meeting with the six beasts earlier.

The Black Plain Empire was already working on its partnerships with the Elves, Dragons, Mammoths, Sea Folk, and Phoenixes, which was hard to ignore. But as much as the Sky Whales more or less understood that he wanted a partnership and that it could be beneficial to all, these beings were more resistant to making a deal with him.
