Whispering Into The Mind

Duncan noticed Asher's surprised look and said, "Tell me, when you took the trial, you were able to possess a human body with no effort, right?"

"Yes, of course," Asher nodded slowly as he remembered possessing that school teacher without doing anything.

"And because you were able to control a human, it was easier for you to manipulate your 'vessel' into giving into you. I can also assume that even after your 'vessel' gained some of your powers, the people around him didn't notice he was Demonized until it was too late," Duncan guessed based on what he knew.

Asher kept nodding as he said, "Yeah. My vessel was just an ordinary and weak human. It was easier than I thought," Asher said while wondering what Duncan was coming to.
