Mottled splotches of tree-filtered sunlight flashed across his body. He ran, wishing he had not looked back at Krasna, guiding himself by the sun, and when he grew tired he used his new knowledge to postpone fatigue. His body would have to pay a price later, but for that he was prepared. He knew now that he must inevitably come into conflict not only with the Faith, but with the Sasso-thing itself. For Sasso held the Gateway. He smiled wryly to himself as he considered fragmentary plans. Perhaps he was El-ve-don after all. The forest thinned to allow glimpses of the Mountains that Move, and then he was clambering up the same barren, rock-strewn slopes he and Krasna had descended so slowly together. He found the entrance to the Chamber without difficulty, for that black hole among the rocks was fixed indelibly in his memory. Then he had to drive himself, push himself step after lagging step down the steep tunnel until he stood amid the warmth and polychromatic glow of the crystal-lined grotto. He felt his spirit, his _self_, float free from his body. It was like swimming in a riptide, requiring a conscious and constant effort to hover near and not be swept out again into the Thin World. And then, deliberately, Eldon's _self_ did strange and terrible things to the body that lay crumpled on the rough floor. There was a psychic pain that ripped and tore at the _self_, more intense and poignant than any purely physical torment, and it continued for a timeless age. When at long last a body staggered up the tunnel its left arm was a stump and one eye blinked and squinted in a ruined, disfigured face. By his own choosing he was outwardly as he had been during those last unhappy months on Earth. The mental changes were invisible. Above the Chamber the mountains grew steeper, rougher, and to an already exhausted cripple the difficulties were almost insuperable. Time after time he narrowly avoided rock slides loosened by the constant earthquakes, and there were ledges where the slightest misstep meant death, and crevices from which noxious, choking fumes puffed in irregular spurts. And always there was the howling, shrieking wind that strove to wreck his precarious balance and send him tumbling to destruction. He wished he had an antigravity egg. With time and proper facilities he could have constructed one. He understood how. But he was not in the Thin World and could not produce one from nothing merely by thinking about it. And he could not have used it anyhow. It was necessary that his maimed body be tortured almost to the point of collapse. The Gateway must be reached through Sasso, and Sasso could be reached only through the Faith. But one who was Of the Faith could not be false to Sasso.
