The realm lord swore, and they made the exchange. He gave them the nine realm hearts, while they gave him the white ephemeral ball. He relaxed as soon as he received the ball. He didn't know that he had been wound up because of it.
His concern was warranted. After all, the white ball is a very important part of his next plans, and there was very little he could do if Legion had refused to make the deal with him.
It would have been a great loss to have GREED lead the Tyrants to their doom only for the final fruits of his labor to be stolen from him. Now that it has returned to its rightful place, he can relax.
Both parties were happy with the exchange. Monarch High Heaven said, "I have to go. I have work to do."
The Tree Father replied, "So do we."
