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?
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 passing.
