When the ships had lifted, they returned across the river to the silence of death. Then his grandfather told him, "Many fine things your father had planned for you: learning and useful work and a life of satisfaction and peace. Do you recall this?""Yes, Grandfather.""The learning you shall have. You will learn patience and resource, the ability of your hands and your mind. You will have useful work: the destruction of evil men. What work could be more useful? This is Beyond; you will find that your work is never done—so therefore you may never know life of peace. However, I guarantee you ample satisfaction, for I will teach you to crave the blood of these men more than the flesh of woman."The old man had been as good as his word.
