Somehow Sarka believed that this white radiance of the abyss held the secret of the omnipotence of Luar, if omnipotence she possessed. That she did seemed sure, else Dalis would not have been with her. Besides, she had asked Sarka and Jaska to swear allegiance to her. Yes the secret was here, in the heart of the lake of white flames.

It might have been the Moon Fountain of Youth, or of omnipotence.

There was no telling, unless Sarka tried an experiment.

His fury at Dalis now knew no bounds, and he was conscious of a desire, too poignant almost to be borne, in some way to circ.u.mvent the arch-traitor. For here in the craters of the Moon Dalis was working out a strange amplification of the scheme which he had, centuries before, proposed to Sarka the First. He was subjecting the people of his Gens to the white flames.

If they immersed themselves voluntarily, they became as Luar was, but still subservient to the will of Dalis--and, in his hands, invincible instruments of war! Dalis had doubtless already been bathed in the flames. Sarka was not sure, for in the home of Luar the white light was so blinding it would have been impossible to make sure that the white radiance clothed the others with Luar.

"That's it!" said Sarka to himself. "That's it! Dalis and those guards at the dais of Luar have already been subjected to the white flames!

The rest who immerse themselves, voluntarily, come forth as Luar and Dalis! Who do not, die. Dalis' manner of forcing the survival of the fittest! His idea of the flood in grandfather's time, only now he causes his selection by flames instead of flood! He believes that only those worthy to survive, and to stand at his back in whatever he conceives to be his need, will guess the secret of the immersion. The others will die!"

What a terrible alternative, when Dalis could as easily have given the secret to all his people! Could have told them how to save themselves!

But it was not Dalis' way. Here, in the beginning of what was to become a dual sovereignty of the Moon, Dalis had already taken thought on the matter of over-population, and was destroying the many that the few--the strongest, most ruthless--might survive! Hundreds of thousands, millions of the Gens of Dalis, stood at the door of life, and did not know how to enter, merely because Dalis withheld the key!

And, pausing in terror before the flames, they died, when a step and a plunge would have saved them all!

"If he lives to be a million, if he lives through everlasting life,"

said Sarka to himself, "and does penance through a thousand reincarnations, Dalis can never atone for this wholesale destruction of humanity! But I ... I wonder!"

Sarka realized the nicety of the revenge of Dalis upon Jaska and himself. Dalis had not given the secret to the prisoners, but by his use of the cubes, he had plunged them into the very heart of the horror, where they could see the suffering of the people of the Gens.

Then, when they had seen and appreciated the horror of it all, they would follow the people of the Gens to death!

But Luar had spoken of thrusting them into the base of the Cone!

Then they were not for the flames after all! How could it be done? The globe composed of the cubes had but to transport the prisoners to the base of the Cone, press against that base, and open to let the prisoners free--and in the heart of the white-blue column they would be hurled outward from the Moon, into s.p.a.ce. The mere prospect of such horror caused the perspiration to break forth anew on the body of Sarka.

But there might be a way.

"I wonder," he asked himself, "if the Earth people in _this_ crater could read my thoughts in spite of their agonies, if I could get my thought to them through the globe? I wonder if, reading my thoughts, they would obey?"

Bit by bit, as parts of a puzzle fall into place, he made his plan, and his heart beat high with excitement. Jaska bent before him to look into his eyes, and he knew that she was trying to read his face. She knew, wise Jaska, that this brilliant lover of hers was making a plan, and she believed in the sure success of it because it would be _his_!

She smiled at him, her courage high, and waited!

Holding the ray director between his body and that of Jaska, he took a terrible, ghastly chance. Dalis had known the secret sign manual of these two; but would the intelligence of the cubes comprehend it? He must take the chance, slender as it seemed. His free hand began to spell out, with all speed, the mad plan he had conceived.

"The white flames are harmless if one plunges into them voluntarily.

Are you afraid to attempt it? No? Then unfasten your clothing, and have it so arranged that you can drop entirely out of it when I give you the signal, which will be a mere widening of the eyes, like this!

You understand? We must go nude into the flames, so that they will bathe our whole bodies! But, when you slip out of your clothing, tear your anti-gravitational ovoid from the skull-pan of your helmet, and hold it in your mouth! Then depend upon me, and have no fear!"

"I have no fear," replied the fingers of Jaska. "I go to death with you if you wish--or to Life!"

Feeling the menace of the cubes almost gripping at his throat as he got into action, Sarka unfastened his own clothing, ripped the ovoid from his helmet, placed it in his mouth. Then, looking at Jaska, he gave her the signal.

Instantly, at her nod, he brought forth the ray director, pressed it with his fingers, directing its muzzle toward the curve of the globe, swinging it around in a circle, cutting out the bottom of the globe of cubes.

The action must have been one of untold surprise to the cubes which made up the globe, for before anything could be done to stay the hand of Sarka, his ray director had cut out the bottom of the globe, and Jaska and himself, divested now of all clothing, had fallen from the globe.

Unbearable heat slashed and tore at them. They still held hands, and when their feet touched upon something solid, they were gasping with the unbelievable heat; and it was ripping at their lungs like talons of white hot steel. But, pausing not at all, Sarka raced ahead with Jaska, and dived straight into the lake of white flames.

As he dived he directed his thoughts toward the people of the Gens who stood, undecided, dying by slow inches, on their little oases in the lake. And this was the thought, which was a command.

"Plunge into the flames! They will not hurt you! Plunge in, and obey my commands, O people of the Gens of Dalis! I, Sarka, command that you obey me! Jaska, who commanded you at the will of Dalis, also commands.

Gather with Jaska and me at the base of the Cone! You have but to follow the converging of the flames!"

Together the two plunged in, and it seemed all at once as though the fire had gone out of the white flames, for they were cool and soothing to the touch. Sarka could feel new life being borne in him, could feel himself revitalized, exalted, lifted to the heights. He suddenly experienced the desire to run, and shout his joy for all to hear. But reason held him. Not thus easily would Luar and Dalis, the traitor, give over their designs against these two.

But in the heart of the flames, they dropped down, while they turned their faces toward the base of the Cone, or where they thought the base to be, even as Sarka gave another command to the now invisible people of the Gens of Dalis.

"Hold your ovoids in your mouths and follow! Obey my will!"

They dropped now to what seemed to be cool flagstones, while above them showed an orifice in a wall, into which those tongues of flame were darting. They paused there, side by side, their faces radiant, and looked back the way they had come.

Coming out of the white flames, like battalions on parade, were the people of the Gens of Dalis--scores and hundreds of them, who had sensed and heeded the mental commands of Sarka. Like genii appearing out of the flames they came, to muster about Sarka and Jaska.

Then, when it seemed that no more were coming, Sarka turned to the base of the Cone, his face high shining with courage and confidence, and stepped straight into the flames that led into the Cone. Beside him came Jaska, while behind him came the people of the Gens of Dalis who dared to do as he had commanded.

They were sucked into the Cone like chips sucked into a whirlpool, and Sarka willed a last command as they entered:

"Quit the column at the lip of the crater, and muster about the aircars!"

CHAPTER XVIII

_The People of Radiance_

The exaltation of Sarka knew no bounds, and looking into the eyes of Jaska, he knew she felt it, too. For her face was shining, and all of her, the wondrous shining brilliance of her, was bathed in the white radiance that mantled Luar. And now, since Jaska too knew that radiance, her beauty was greater even than that of Luar. Sarka thrilled anew at the glory of her.

But even as he stepped into the base of the Cone, he stepped out of the blue column at the lip of the Moon-crater. Swift as light, and swifter, had been the flight upward from the Cavern of the Cone; yet, so keen were his perceptions, he knew when he had pa.s.sed through the chamber of the bluish glow, into which he and Jaska had first dropped upon arrival.

Now they were on the lip of the crater, and the people of the Gens who had followed him, were slipping out of the blue column, like insects out of a flame, and converging on the aircars whose tentacles still waved as they had when Sarka had last seen them.

Sarka looked at these people in amazement. To him there was a divinity now about their nudeness which nudity never before had suggested to him. For the people shone, and there was something glorious in those divinely white bodies. They reminded Sarka of his people's books of antiquity, and his childhood's pictures of angels....

But the effect of those white flames!...

There was no explaining it. But Sarka felt that whatever he willed to do he could do; that whatever he wished for was his, whether it was his by right or no. He felt that he could move mountains, with only the aid of his hands. Looking at Jaska he conceived all sorts of new beauty in her, for she was the brightest, to him, of all the people who had pa.s.sed through the lake of white flames, and been cleansed in their heat.

"No wonder Luar has mastered the Moon!" he cried to Jaska. "For when she was bathed in the white flames, her will is paramount!"
