This layer of the Abyss World had now completely become Charles's private domain.
Every so often, there was a demon settlement.
Although demons still fought amongst themselves as they had before, it was strictly forbidden within the settlements.
That way, fighting was allowed, but taxes could not be avoided.
Now, throughout the entire Abyss World, there were only two things that could not be avoided: paying taxes and death.
