This meeting must be very important. He is also not meeting with a friend. They are not buddies and there is no reason for the first sage to like him. Anything he says can and may be used against him. It is best if he observes instead of participating in whatever this is. Those that listen and observe see more than those who talk. It will prevent him from falling into a trap.
"So you have decided to keep quiet. That is smart. To prove that I mean you no harm I'll tell you how I found out about your secrets. Your soul is powerful, very powerful. Anyone that can't see how powerful your soul is is simply blind. I am not blind. As such, I can tell that you're a king of law even though you haven't left your forge since you broke through."
