A man of the Night's Watch lives his life for the realm. Not for a king, nor a lord, nor the honor of this house or that house, neither for gold nor glory nor a woman's love, but for the realm, and all the people in it. A man of the Night's Watch takes no wife and fathers no sons. Our wife is duty. Our mistress is honor. And you are the only sons we shall ever know.
