Basil frowned while looking at the dying Jackson's sibling. While trying to figure out the way Charles' Spell work, he was also recalling the aides of Charles. Basil had met Charles once, however he had never had a feud with him.
He knew about Charles quite well. According to his memories, Charles had had three aides. All of them had been his disciples who he had had nurtured since young. They had the same thing in common which was their violent nature.
They were known with their brutality and sick hobby. They liked to toy with their victims and had often played "Catch and Run", which had been pretty much them chasing the victims they had intentionally let go, then killing those victims when they were caught.
To describe them simply, they were breathing trash. As Basil had coincidentally met two of them, he had decided to contribute to society by eliminating them early.
