In a few brief, highly technical words, Sarka told his beloved how to talk with him in the manner which he had never before explained to her. They had used telepathy before, countless times, but they had not cared who heard--while now secrecy in all things was the prime essential for success, even for life. When he had told her, and she replied, "I understand perfectly, and it seems quite easy," they turned and surveyed the heavens, out of which, by this new miracle of the secret exit dome, they had dropped to the face of the Moon. Away across the space between worlds, its transfiguration plainly visible to the two, they could make out and identify the world from which they had come. Save that they knew themselves standing on the Moon, they would have thought as far as appearances went, that the place where they had come was the Moon, many times enlarged. It seemed incredible that they had come so far in the twinkling of an eye; but that they had was proved by the fact of their physical presence. "Look, Jaska!" said Sarka suddenly. "See how our Earth glows, as though it were afire inside!" * * * * * They stared at the great circular yellowish flame that he pointed out, and Sarka, always the scientist whose science was one of exactness, tried to estimate just where, on the Earth's surface, the glow was. "Jaska," he said again, "that glow comes out of the heart of the Gens area which Dalis ruled! And no one lives there, since Dalis' Gens flew out to do battle! That's why we did not know of it before we left! That glow, somehow, beloved, is the cause of the outward-from-the-Earth journey of the Moon! First we must locate the Moon-source of the glow, and render it incapable of further forcing itself away! For do you realize that, unless we do so, we will never again see home?" Jaska said nothing, but her eyes were troubled for a moment. Then she smiled again. "What care I if I become a prisoner on the Moon, if you are with me?" Sarka was just now realizing the wonder of this raven-haired woman whom, knowing her for half a century as he had, he had just known so little after all. "If we seem in danger of discovery, Jaska," he said to her, "drop down instantly into the ashes, for if we are discovered by Dalis...." He left it there and, with a deep intake of breath, started away for the nearest and highest hill. They desired to walk, yet found walking almost impossible, as they could not keep their feet on the ground save by the exercise of a really incredible effort of will. So, despairing of keeping their feet in contact with the ashes, they flew just above them, heading for the nearest weird-looking ridge. * * * * * In the strange light, which was oddly like moonlight in some painted desert of Earth, shapes were distorted and somehow menacing, colors were raw, almost bleeding--and distances that seemed but a step required hours to traverse.
