Bab 19: Chapter Eighteen: "The War of Humans and Monsters."

"Why did the humans attack? Indeed, it seemed that they had nothing to fear. Humans are unbelievably strong. It would take the SOUL of nearly every monster... Just to equal the power of a single human SOUL. But humans have one weakness. Ironically, it is the strength of thier SOUL. It's power allows it to persist outside the human body, even after death. If a monster defeats a human, they can take it's SOUL. A monster with a human SOUL... A horrible beast with unfathomable power. It's an illustration of a strange creature... There's something very unsettling about this drawing."
