An experienced warrior and huntsman like Tirian can always wake up at the time he wants. So he gave himself till nine o’clock that night and then put all worries out of his head and fell asleep at once. It seemed only a moment later when he woke but he knew by the light and the very feel of things that he had timed his sleep exactly. He got up, put on his helmet.and.turban (he had slept in his mail shirt), and then shook the other two till they woke up. They looked, to tell the truth, very grey and dismal as they climbed out of their bunks and there was a good deal of yawning.
