Prince could indeed just use his intent to talk now—that was quite cool, Damian had to admit. And somehow, it was much faster than talking. Damian thought about inscribing the spell on his sacrium bracers.. just to check out how they worked.
Now that the guy had free speech, Damian grabbed both his sacrium arms and said, "Keep my shit out of any conversations, or I will break your body into a hundred pieces and store it in a place darker than death itself."
Prince just replied with, 'Yes, sir.'
The only thing powering its actions was Damian's own mana. Damian actually had full control over all the spells he could cast—Prince knew it too. Without him, he would just be a man trapped in an inescapable object all his life. Damian wasn't worried about him leaking any of his secrets; he wouldn't have done it if he was.
