as our buildings and our gardens. We did not know that it was against the Law....
"I was one of those who found the way to change the living cell. We used the unseen force that comes from the Land of the Gods beyond the sky, and we so harnessed it that we could build from the living flesh as the potter builds from the clay. We healed the halt and the maimed, and made those stand tall and straight who came crooked from the egg, and for a time we were as brothers to the gods themselves. I myself, even I, knew the glory of perfection. And then came the reckoning.
"The cell, once made to change, would not stop changing. The growth was slow, and for a while we did not notice it, but when we did it was too late. We were becoming a city of monsters. And the force we had used was worse than useless, for the more we tried to mould the monstrous flesh to its normal shape, the more the stimulated cells grew and grew, until the bodies we laboured over were like things of wet mud that flow and change even as you look at them.
"One by one the people of the city destroyed themselves. And those of us who were left realized the judgment of the gods, and our duty. We made all things ready, and let the Red Sea hide us forever from our own kind, and those who should come after.
"Yet we did not destroy our knowledge. Perhaps it was our pride only that forbade us, but we could not bring ourselves to do it. Perhaps other gods, other races wiser than we, can take away the evil and keep only the good. For it is good for all creatures to be, if not perfect, at least strong and sound.
"But heed this warning, whoever you may be that listen. If your gods are jealous, if your people have not the wisdom or the knowledge to succeed where we failed in controlling this force, then touch it not! Or you, and all your people, will become as I."

The voice stopped. Stark moved back again, and said to Treon incredulously, "And your family would ignore that warning?"
Treon laughed. "They are fools. They are cruel and greedy and very proud. They would say that this was a lie to frighten away intruders, or that human flesh would not be subject to the laws that govern the flesh of reptiles. They would say anything, because they have dreamed this dream too long to be denied."
Stark shuddered and looked at the black door. "The thing ought to be destroyed."
"Yes," said Treon softly.
His eyes were shining, looking into some private dream of his own. He started forward, and when Stark would have gone with him he thrust him back, saying, "No. You have no part in this." He shook his head.
"I have waited," he whispered, almost to himself. "The winds bade me wait, until the day was ripe to fall from the tree of death. I have waited, and at dawn I knew, for the wind said, Now is the gathering of the fruit at hand."
He looked suddenly at Stark, and his eyes had in them a clear sanity, for all their feyness.
"You heard, Stark. 'We made those stand tall and straight who came crooked from the egg.' I will have my hour. I will stand as a man for the little time that is left."
He turned, and Stark made no move to follow. He watched Treon's twisted body recede, white against the red dusk, until it passed the monstrous watcher and came to the black door. The long thin arms reached up and pushed the bar away.
The door swung slowly back. Through the opening Stark glimpsed a chamber that held a structure of crystal rods and discs mounted on a frame of metal, the whole thing glowing and glittering with a restless bluish light that dimmed and brightened as though it echoed some vast pulse-beat. There was other apparatus, intricate banks of tubes and condensers, but this was the heart of it, and the heart was still alive.
Treon passed within and closed the door behind him.
Stark drew back some distance from the door and its guardian, crouched down, and set his back against the wall. He thought about the apparatus. Cosmic rays, perhaps—the unseen force that came from beyond the sky. Even yet, all their potentialities were not known. But a few luckless spacemen had found that under certain conditions they could do amazing things to human tissue.
It was a line of thought Stark did not like at all. He tried to keep his mind away from Treon entirely. He tried not to think at all. It was dark there in the corridor, and very still, and the shapeless horror sat quiet in the doorway and waited with him. Stark began to shiver, a shallow animal-twitching of the flesh.
He waited. After a while he thought Treon must be dead, but he did not move. He did not wish to go into that room to see.
He waited.
Suddenly he leaped up, cold sweat bursting out all over him. A crash had echoed down the corridor, a clashing of shattered crystal and a high singing note that trailed off into nothing.
The door opened.
A man came out. A man tall and straight and beautiful as an angel, a strong-limbed man with Treon's face, Treon's tragic eyes. And behind him the chamber was dark. The pulsing heart of power had stopped.
The door was shut and barred again. Treon's voice was saying, "There are records left, and much of the apparatus, so that the secret is not lost entirely. Only it is out of reach."
He came to Stark and held out his hand. "Let us fight together, as men. And do not fear. I shall die, long before this body changes." He smiled, the remembered smile that was full of pity for all living things. "I know, for the winds have told me."
Stark took his hand and held it.
"Good," said Treon. "And now lead on, stranger with the fierce eyes. For the prophecy is yours, and the day is yours, and I who have crept about like a snail all my life know little of battles. Lead, and I will follow."
Stark fingered the collar around his neck. "Can you rid me of this?"
Treon nodded. "There are tools and acid in one of the chambers."
He found them, and worked swiftly, and while he worked Stark thought, smiling—and there was no pity in that smile at all.
They came back at last into the temple, and Treon closed the entrance to the catacombs. It was still night, for the square was empty of slaves. Stark found Egil's weapon where it had fallen, on the ledge where Egil died.
"We must hurry," said Stark. "Come on."

The island was shrouded heavily in mist and the blue darkness of the night. Stark and Treon crept silently among the rocks until they could see the glimmer of torchlight through the window-slits of the power station.
There were seven guards, five inside the blockhouse, two outside to patrol.
When they were close enough, Stark slipped away, going like a shadow, and never a pebble turned under his bare foot. Presently he found a spot to his liking and crouched down. A sentry went by not three feet away, yawning and looking hopefully at the sky for the first signs of dawn.
Treon's voice rang out, the sweet unmistakable voice. "Ho, there, guards!"
The sentry stopped and whirled around. Off around the curve of the stone wall someone began to run, his sandals thud-thudding on the soft ground, and the second guard came up.
"Who
