“Do you know what the cold does to stone, King Carrick?” I ask. He pauses and tilts his head as he looks at me. I gesture through the doorway, to the crumbling stone walls that are worn and abraded. “Stone has rifts and crevices. Weaknesses. It may look invincible and strong, but the cold can exploit those things. Moisture delves into those cracks and fissures, and when it freezes, it ruins. Stone can’t withstand it forever. In the end, cold will always win out.”
