"Great then," William clasped his hands, acting carefree about all this, "first you'll have to let a totem on your chest. If you tried to remove it by force, it'll detonate your heart. If you tried to resist a direct order from me, you'd get killed right on the spot. How about that?"
William looked at Moore, and like seeing a man who lost everything and was willing to risk it all to survive, Moore nodded without any speck of hesitation.
"Killing without my permission isn't allowed," after William drew lots of small symbols over Moore's chest, he finally said, "you aren't allowed to speak with any of the dark spirit masters, including your former lord, without my permission. You aren't allowed to betray me, disclose any secrets or intel about me, my team, my guild, and any of my business to anyone. Is that clear?"
William stated his conditions down, and with every and each one of them, Moore obediently nodded.
