Hanson checked the rigging with half his mind, while the other half raced in a crazy circle of speculation. Mandrakes and mandrake-men, zombie-men, from the past and multiple revivals! A sky that fell in great chunks. What came next in this ridiculous world in which he seemed to be trapped? As if in answer to his question, there was a sudden, coruscating flare from above. Hanson's body reacted instinctively. His arm came up over his eyes, cutting off the glare. But he managed to squint across it, upwards toward what was happening in the cracked dome. For a split second, he thought that the sun had gone nova. He was wrong, but not by too much. Something had happened to the sun. Now it was flickering and flaming, shooting enormous jets of fire from its rim. It hovered at the edge of a great new hole and seemed to be wobbling, careening and losing its balance. There was a massive shriek of fear and panic from the horde of slaves. They began bellowing like the collective death-agony of a world. Most of them dropped their ropes and ran in blind panic, trampling over each other in their random flight for safety. The human overseers were part of the same panic-stricken riot. Only the mandrakes stood stolidly in place, flicking each running man who passed them. Hanson flung himself face down on the stone. There was a roar of tortured air from overhead and a thundering sound that was unlike anything except the tearing of an infinity of cloth combined with a sustained explosion of atomic bombs. Then it seemed as if the thunderbolt of Thor himself had blasted in Hanson's ears. The sky had ripped again, and this time the entire dome shook with the shock. But that wasn't the worst of it. The sun had broken through the hole and was falling! VII The fall of the sun was seemingly endless. It teetered out of the hole and seemed to hover, spitting great gouts of flame as it encountered the phlogiston layer. Slowly, agonizingly, it picked up speed and began its downward rush. Unlike the sky, it seemed to obey the normal laws of inertia Hanson had known. It swelled bit by bit, raging as it drew nearer. And it seemed to be heading straight for the pyramid. The heat was already rising. It began to sear the skin long before the sun struck the normal atmosphere. Hanson could feel that he was being baked alive. The blood in his arteries seemed to bubble and boil, though that must have been an illusion. But he could see his skin rise in giant blisters and heal almost at once to blister again. He screamed in agony, and heard a million screams around him. Then the other screams began to decrease in numbers and weaken in volume, and he knew that the slaves were dying.
