The king was the one that made the decision after realizing that it was impossible for them to be able to deal with the humans with the current capabilities that they possessed.
Among the six elders of the sea race, two of them had resisted tremendously, and in the end, they ended up being killed. After all, Henry did not entertain anybody that wanted to go against him. And since that was the case, it was better for him to get rid of them.
As for the rest of the leaders of the sea race, he made them sign a contract that they would be vassals of the Domination Star territory. As for the time that they were going to be subordinates of the Domination Star territory, it was going to be for infinity.
