Territory Migration
After handling the matter about the attack from the sea race, Henry decided to focus on another matter. That was due to the fact that there was yet another race that was located very close to the territory.
It was the dark race. The enmity between him and the dark race was not something that could be ignored at all. After all, during the previous stages of the apocalypse, they had completely eliminated the members of the dark race, not giving them any chance of establishing themselves in this world.
With him doing that, it was very clear that the dark race would not like it. Additionally, he had encountered a higher ranking member of the dark race, through the clone that he had fought before.
From that previous encounter, it was clear that they had already established a great enmity that could not be cleared out.
