" In the wars it had been different. Men dropped from the columns all the time on the long marches, in the cold months. First they fell to the back, then they fell behind, then they fell over. The cold, the sick, the wounded. Logen shivered and hunched his shoulders. At first he’d tried to help them. Then he became grateful he wasn’t one of them. Then he stepped over the corpses and hardly noticed them. You learn to tell when someone isn’t getting up again. He looked at Malacus Quai. One more death in the wild was nothing to remark upon. You have to be realistic, after all.
The apprentice started from his fitful sleep and tried to push himself up. His hands were shaking bad. He looked up at Logen, eyes glittering bright. “I can’t get up,” he croaked.
“I know. I’m surprised you made it this far.” It didn’t matter so much now. Logen knew the way. If he could find that track he might make twenty miles a day.
“If you leave me some of the food… perhaps… after you get to the library… someone…”
“No,” said Logen, setting his jaw. “I need the food.”
Quai made a strange sound, somewhere between a cough and a sob.
Logen leaned down and set his right shoulder in Quai’s stomach, pushed his arm under his back. “I can’t carry you forty miles without it. "
