Then the Gnome turned back to Sarka and Jaska. By a pressure of tiny feet, he tried to indicate that Sarka and Jaska should unclasp their hands. But they only clung the tighter, and now threw their arms about each other.
The Gnome desisted, much to the joy of the lovers, while Sarka studied the cubes, wondering what their mission was with Jaska and himself.
Slowly, together, the cubes began to lose their bluish glow, their cube shape--to vanish utterly.
In a trice, still locked in each other"s arms, Sarka and Jaska saw the Gnomes through what appeared to be an even bluer haze. Besides, the heat of the abyss no longer tortured them, and their bodies were cooling in a way that was unbelievably refreshing.
"What is it, beloved?" whispered Jaska. "What is it?"
Sarka stared at the Gnomes, now in retreat, capering as they had first capered when the two had fallen into their hands, toward the door by which all had entered. Mystified, Sarka put forth his hand. It came in contact with something solid, and oddly warm, which stirred an instantly responsive chord in the brain of Sarka.
This feeling was the same as he experienced when he had lifted those cubes and hurled them into the crater--where they had dissolved in falling, and instantly reappeared, each under its own aircar!
"Jaska!" he explained. "Jaska! The cubes have dissolved themselves, and have reformed in the shape of a globe, as a protective covering about us, to protect us from the heat of the abyss! Apparently we are not to be killed at once! These cubes are slaves of the Gnomes, of whom Luar is ruler!"
They were indeed locked inside a globe, a globe whose integral parts were the cubes of their acquaintance; and the atmosphere of the interior was not uncomfortable, but otherwise. Sarka and Jaska were feeling normal for the first time since they had landed on the Moon.
But what was the meaning of this strange imprisonment?
They were soon to know!
For the globe which enclosed them, moved to the edge of the flaming abyss, and dropped into the bluish glow! It did not drop heavily, like a falling object on Earth, but rather floated downward, right into the heart of the flames. At this new manifestation of the strangeness of science on the Moon, Sarka was at once all scientist himself, striving to find adequate answers for things which, from cause to effect, were entirely new to him. With Jaska still clasped close against him, he seated himself in the base of the globe and studied the area through which they were pa.s.sing.
Blue flames which seemed to be born somewhere, an infinite distance below them; blue flames which he knew to be the element that, shot outward from the great cone, had forced the Moon away from the Earth.
No sound of the roaring flames came through the globe, but every movement of them was visible.
Sarka turned and peered through the bottom of the globe; but all he could see below were the flames, a molten indigo lake of them. Now, as they floated downward, the glow was giving away to lighter blue, to white, almost pure white, like the radiance which covered Luar like a mantle.
Sarka felt himself on the eve of vast important discoveries, and the scientist in him made him, for the moment, almost forget the woman at his side. Jaska, unbothered about anything, now that Sarka was at her side, regarded his expression of deep concentration with a tolerant smile.
Whiter now was the light, and faster fell the globe which held the two.
The color of the globe, now fallen below the area of blue, had taken on, chameleonlike, the color of the white flames that bathed it.
Then, apparently right in the center of a lake of white flames, though Sarka could see no solid place on which the globe had landed, the globe came to rest.
Now everything was plain to see, and Sarka studied his surroundings with new interest. He felt a mounting sensation of scalp-p.r.i.c.kling horror.
For, scattered throughout the lake of white flames, in all directions, as far as the eye could reach--standing alone, suffering untold agonies, from the expressions on their faces--were people of the Gens of Dalis!
No longer were they clothed in green and wearing on breast and back the yellow stars of their Gens. Now they were nude as they had come into the world and standing there, each was holding out hands in horror, to hold back myriads of the Gnomes, who would have forced them to submerge themselves in the white flames of the lake!
Was the Gens of Dalis being burned alive? What was the meaning of this?
For a moment, filled with horror, Sarka looked away from the spectacle. Off to his right, as he sat, he noted that the flames, which here seemed lighter than they had in high levels, were converging on a single spot toward the side of the lake of white flames--as smoke converges on the base of a chimney leading outward to the air!
He knew as he stared that he was gazing at the spot where the bluish column of the cone was born!
Shaking his head, he turned back to the mighty spectacle of this horrible thing that was being done to the people of the Gens of Dalis.
In his brain there suddenly crashed a thought whose source he could only guess at, whose meaning mystified him more than anything yet experienced. The thought might have emanated from Luar, or from Dalis.
But the more he thought of the matter, the more he thought how the phrasing of the thought was like the telepathy of Sarka the Second, now thousands of miles away, upon the Earth. And this was the thought:
"If they fight the flames, the flames will destroy them! If they go into them freely, voluntarily, they will be rendered immune to heat and to cold, to life and to death. But it is better that they die, for Earth"s sake!"
What did it mean?
Sarka thought of the radiant white light which perpetually bathed the person of Luar, and thought that he had somehow been given a hint of its source. If the Gens of Dalis were voluntarily bathed in the lake of white flames, would they become as Luar?
Somehow, though he knew that such bathing would save their lives, the idea filled him anew with horror. He found himself torn between two duties. If he sent his thought out there to the Gens of Dalis, people of Earth, his people, they would be saved, but might forever become allies of the people of the Moon. If Sarka did not tell them, they would die--and there were millions of them.
But his science had always been a science of Life, and it still was.
"Enter the flames!" he telepathically bade his people. "Enter the flames!"
But they did not heed him, and for the first time the atmosphere of the interior of the globe seemed filled with savage, abysmal menace!
Plain to Sarka was the meaning of that menace: The cubes which composed this globe were loyal to their masters, the masters to a mistress, Luar, and would countenance no meddling.
Likewise it was impossible, if the Gnomes willed it to the cubes, for Sarka to transmit his thoughts to the Gens of Dalis through the transparent walls of the globe!
They were prisoners, indeed, of Dalis and of Luar!
But could Sarka and Jaska turn their new-found knowledge to their own use? Sarka was thinking back, back to one of the ancient tomes of his people. It spoke, someplace, of a man who had got trapped in the heart of a seething volcano, where the heat of it had cured him of his illnesses, made him whole again, given him new youth and freshness.
But since the cubes could forestall his transmission of thought, and perhaps could read and understand thoughts, how was he to tell Jaska?
How show her that a way of deliverance had been given into their hands, if they only possessed the courage to use it!
Again came that thought, which Sarka recognized as the telepathy of his father:
"Courage! You will win, and Jaska with you!"
Thoughts could come in to them then, but could not go out. Or did it mean that the cubes, or the masters of the cubes, did not care if the prisoners received messages from outside, because they knew themselves capable of frustrating anything the prisoners planned? Perhaps. More than likely that was it.
But, looking through the bottom of the globe, into the sea of white flames below, Sarka gripped more tightly his ray director, and tried to marshal the forces of his courage. There was surely some way of escape. Some way out of their strange predicament.
