“Fear,” Raum replied simply.
Charam was not at a loss for rocks. He found one that looked more solid than the others and slammed it down on the chain but it barely nicked the metal. Again and again he tried until the rock cracked and split between his hands.
Another tremor sent more rocks to the floor, but try as he might, Charam could find none that would do more than carve bright silver lines into the metal. After each failure he found himself exploring further and further into the pit. There were many rocks that looked like they were up to the task, but he had tried similar specimens, and they had been useless. He needed something more substantial—something that would not crack and shatter under the pressure.
