Nor was it incredible that in the ancient nebula that was the matrix of our solar system similar, or rather _dissimilar_, particles in all but the subtle essence we call life, might have become entangled and, resisting every cataclysm as they had resisted the absolute zero of outer space, found in these caverned spaces their proper environment to develop into the race of the Silent Ones and--only _they_ could tell what else! "They say," the handmaiden's voice was surer, "they say that in their--cradle--near earth's heart they grew; grew untroubled by the turmoil and disorder which flayed the surface of this globe. And they say it was a place of light and that strength came to them from earth heart--strength greater than you and those from which you sprang ever derived from sun. "At last, ancient, ancient beyond all thought, they say again, was this time--they began to know, to--to--realize--themselves. And wisdom came ever more swiftly. Up from their cradle, because they did not wish to dwell longer with those--others--they came and found this place. "When all the face of earth was covered with waters in which lived only tiny, hungry things that knew naught save hunger and its satisfaction, _they_ had attained wisdom that enabled them to make paths such as we have just travelled and to look out upon those waters! And _laya_ upon _laya_ thereafter, time upon time, they went upon the paths and watched the flood recede; saw great bare flats of steaming ooze appear on which crawled and splashed larger things which had grown from the tiny hungry ones; watched the flats rise higher and higher and green life begin to clothe them; saw mountains uplift and vanish. "Ever the green life waxed and the things which crept and crawled grew greater and took ever different forms; until at last came a time when the steaming mists lightened and the things which had begun as little more than tiny hungry mouths were huge and monstrous, so huge that the tallest of my _Akka_ would not have reached the knee of the smallest of them. "But in none of these, in _none_, was there--realization--of themselves, say the Three; naught but hunger driving, always driving them to still its crying.
