" Xas put his face close to Sobran's and said, soft and succinct, "Listen, and take this in. The terms of the pact are this: 'Xas shall go freely. God shall have his pains and Lucifer his pleasures.' So, if you please yourself and me the way you want, Sobran, you will be pleasing the devil. And I will not give you to him. "
