“Until the others got their mines sunk.” O’Neill stepped carefully through the sagging entrance, climbed a heap of debris that had been tossed against the slit from inside, and found himself within the factory—an expanse of confused wreckage, without pattern or meaning.

“Entropy,” Morrison breathed, oppressed. “The thing it always hated. The thing it was built to fight. Random particles everywhere. No purpose to it.”

“Down underneath,” O’Neill said stubbornly, “we may find some sealed enclaves. I know they got so they were dividing up into autonomous sections, trying to preserve repair units intact, to re-form the composite factory.”

“The moles got most of them, too,” Morrison observed, but he lumbered after O’Neill.

Behind them, the workmen came slowly. A section of wreckage shifted ominously and a shower of hot fragments cascaded down.

“You men get back to the trucks,” O’Neill said. “No sense endangering any more of us than we have to. If Morrison and I don’t come back, forget us—don’t risk sending a rescue party.” As they left, he pointed out to Morrison a descending ramp still partially intact. “Let’s get below.”

Silently, the two men passed one dead level after another. Endless miles of dark ruin stretched out, without sound or activity. The vague shapes of darkened machinery, unmoving belts and conveyer equipment were partially visible, and the partially completed husks of war projectiles, bent and twisted by the final blast.

“We can salvage some of that,” O’Neill said, but he didn’t actually believe it. The machinery was fused, shapeless. Everything in the factory had run together, molten slag without form or use. “Once we get it to the surface ...”

“We can’t,” Morrison contradicted bitterly. “We don’t have hoists or winches.” He kicked at a heap of charred supplies that had stopped along its broken belt and spilled halfway across the ramp.

“It seemed like a good idea at the time,” O’Neill said as the two of them continued past vacant levels of machines. “But now that I look back, I’m not so sure.”
