"Some of them seem to be Indians," Hanson noted. He hadn't paid too much attention, but the slaves seemed to be from every possible background.

Barg nodded. "Aztecs from a place called Tenochtitlan. Twenty thousand of them got sacrificed in a bunch for some reason or other. Poor devils. They think this is some kind of heaven. They tell me this is easy work compared to the type they had to undergo. The Satheri like to get big bunches through in one conjuration, like the haul they made from the victims of somebody named Tamerlane." He tested a rope, then dropped to a sitting position on the edge of the block. "I'll let you stay up to call signals from here. Only watch it. That overseer has his eyes on you. Make sure the ropes stay tight while we see if the thing can be moved."

He started to slip over the side, hanging by his fingertips. Something caught, and he swore. With one hand, he managed to free his breechclout and drag out the thin volume that was lodged between his groin and the block. "Here, hold this for me until we meet tonight. You've got more room to hide it in your cloth than I have." He tossed it over quickly, then dropped from sight to land on the ground below.

Hanson shoved the book out of sight and tried to act busy again. The mandrake overseer had started ponderously toward him. But in a moment the thing's attention was directed to some other object of torture.

Hanson braced himself as the lines of slaves beneath him settled themselves to the ropes. There was a loud cracking of whips and a chorus of groans. A small drum took up a beat, and the slaves strained and tugged in unison. Ever so slowly, the enormous block of stone began to move, while the ropes drew tighter.

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.
