glinting through the red.
Vines like drifts of snow cascading down the stones. Gardens with close-clipped turf and flowers lifting bright on their green stalks, their petals open to a daylight that was gone, their head bending as though to some forgotten breeze. All neat, all tended, the branches pruned, the fresh soil turned this morning—by whose hand?
Stark remembered the great forest dreaming at the bottom of the gulf, and shivered. He did not like to think how long ago these flowers must have opened their young bloom to the last light they were ever going to see. For they were dead—dead as the forest, dead as the city. Forever bright—and dead.
Stark thought that it must always have been a silent city. It was impossible to imagine noisy throngs flocking to a market square down those immense avenues. The black walls were not made to echo song or laughter. Even the children must have moved quietly along the garden paths, small wise creatures born to an ancient dignity.
He was beginning to understand now the meaning of that weird forest. The Gulf of Shuruun had not always been a gulf. It had been a valley, rich, fertile, with this great city in its arms, and here and there on the upper slopes the retreat of some noble or philosopher—of which the castle of the Lhari was a survivor.
A wall or rock had held back the Red Sea from this valley. And then, somehow, the wall had cracked, and the sullen crimson tide had flowed slowly, slowly into the fertile bottoms, rising higher, lapping the towers and the tree-tops in swirling flame, drowning the land forever. Stark wondered if the people had known the disaster was coming, if they had gone forth to tend their gardens for the last time so that they might remain perfect in the embalming gases of the sea.

The columns of slaves, herded by overseers armed with small black weapons similar to the one Egil had used, came out into a broad square whose farther edges were veiled in the red murk. And Stark looked on ruin.
A great building had fallen in the centre of the square. The gods only knew what force had burst its walls and tossed the giant blocks like pebbles into a heap. But there it was, the one untidy thing in the city, a mountain of debris.
Nothing else was damaged. It seemed that this had been the place of temples, and they stood unharmed, ranked around the sides of the square, the dim fires rippling through their open porticoes. Deep in their inner shadows Stark thought he could make out images, gigantic things brooding in the spark-shot gloom.
He had no chance to study them. The overseers cursed them on, and now he saw what use the slaves were put to. They were clearing away the wreckage of the fallen building.
Helvi whispered, "For sixteen years men have slaved and died down here, and the work is not half done. And why do the Lhari want it done at all? I'll tell you why. Because they are mad, mad as swamp-dragons gone musth in the spring!"
It seemed madness indeed, to labour at this pile of rocks in a dead city at the bottom of the sea. It was madness. And yet the Lhari, though they might be insane, were not fools. There was a reason for it, and Stark was sure it was a good reason—good for the Lhari, at any rate.
An overseer came up to Stark, thrusting him roughly toward a sledge already partly loaded with broken rocks. Stark hesitated, his eyes turning ugly, and Helvi said,
"Come on, you fool! Do you want to be down flat on your back again?"
Stark glanced at the little weapon, blunt and ready, and turned reluctantly to obey. And there began his servitude.
It was a weird sort of life he led. For a while he tried to reckon time by the periods of work and sleep, but he lost count, and it did not greatly matter anyway.
He laboured with the others, hauling the huge blocks away, clearing out the cellars that were partly bared, shoring up weak walls underground. The slaves clung to their old habit of thought, calling the work-periods "days" and the sleep-periods "nights".
Each "day" Egil, or his brother Cond, came to see what had been done, and went away black-browed and disappointed, ordering the work speeded up.
Treon was there also much of the time. He would come slowly in his awkward crabwise way and perch like a pale gargoyle on the stones, never speaking, watching with his sad beautiful eyes. He woke a vague foreboding in Stark. There was something awesome in Treon's silent patience, as though he waited the coming of some black doom, long delayed but inevitable. Stark would remember the prophecy, and shiver.
It was obvious to Stark after a while that the Lhari were clearing the building to get at the cellars underneath. The great dark caverns already bared had yielded nothing, but the brothers still hoped. Over and over Cond and Egil sounded the walls and the floors, prying here and there, and chafing at the delay in opening up the underground labyrinth. What they hoped to find, no one knew.
Varra came, too. Alone, and often, she would drift down through the dim mist-fires and watch, smiling a secret smile, her hair like blown silver where the currents played with it. She had nothing but curt words for Egil, but she kept her eyes on the great dark Earthman, and there was a look in them that stirred his blood. Egil was not blind, and it stirred his too, but in a different way.
* * * * *
Zareth saw that look. She kept as close to Stark as possible, asking no favours, but following him around with a sort of quiet devotion, seeming contented only when she was near him. One "night" in the slave barracks she crouched beside his pallet, her hand on his bare knee. She did not speak, and her face was hidden by the floating masses of her hair.
Stark turned her head so that he could see her, pushing the pale cloud gently away.
"What troubles you, little sister?"
Her eyes were wide and shadowed with some vague fear. But she only said, "It's not my place to speak."
"Why not?"
"Because...." Her mouth trembled, and then suddenly she said, "Oh, it's foolish, I know. But the woman of the Lhari...."
"What about her?"
"She watches you. Always she watches you! And the Lord Egil is angry. There is something in her mind, and it will bring you only evil. I know it!"
"It seems to me," said Stark wryly, "that the Lhari have already done as much evil as possible to all of us."
"No," answered Zareth, with an odd wisdom. "Our hearts are still clean."
Stark smiled. He leaned over and kissed her. "I'll be careful, little sister."
Quite suddenly she flung her arms around his neck and clung to him tightly, and Stark's face sobered. He patted her, rather awkwardly, and then she had gone, to curl up on her own pallet with her head buried in her arms.
Stark lay down. His heart was sad, and there was a stinging moisture in his eyes.
The red eternities dragged on. Stark learned what Helvi had meant when he said that the mind broke before the body. The sea-bottom was no place for creatures of the upper air. He learned also the meaning of the metal collars, and the manner of Tobal's death.
Helvi explained.
"There are boundaries laid down. Within them we may range, if we have the strength and the desire after work. Beyond them we may not go. And there is no chance of escape by breaking through the barrier. How this is done I do not understand, but it is so, and the collars are the key to it.
"When a slave approaches the barrier the collar brightens as though with fire, and the slave falls. I have tried this myself, and I know. Half-paralyzed, you may still crawl back to safety. But if you are mad, as Tobal was, and charge the barrier strongly...."
He made a cutting motion with his hands.
Stark nodded. He did not attempt to explain electricity or electronic vibrations to Helvi, but it seemed plain enough that the force with which
