The upper opening to the cavern of the fog was now so far above him that he had to strain to see it. And that warmth which had been there was gone. A dank chill wrapped him here, dampened the holds to which he clung until he was afraid of slipping. While the murmur of the water grew louder, until its _slap-slap_ sounded within arms' distance. His boot toe skidded from a niche. Shann fought to hold on with numbed fingers. The other foot went. He swung by his hands, kicking vainly to regain a measure of footing. Then his arms could no longer support him, and he cried out as he fell. Water closed about him with an icy shock which for a moment paralyzed him. He flailed out, fighting the flood to get his head above the surface where he could gasp in precious gulps of air. There was a current here, a swiftly running one. Shann remembered the one which had carried him into that cavern in which the Warlockians had their strange dwelling. Although there were no clusters of crystals in this tunnel to supply him with light, the Terran began to nourish a faint hope that he was again in that same stream, that those light crystals would appear, and that he might eventually return to the starting point of this meaningless journey. So he strove only to keep his head above water. Hearing a splashing behind him, he called out: "Thorvald?" "Lantee?" The answer came back at once; the splashing grew louder as the other swam to catch up. Shann swallowed a mouthful of the water lapping against his chin. The taste was brackish, but not entirely salt, and though it stung his lips, the liquid relieved a measure of his thirst. Only no glowing crystals appeared to stud these walls, and Shann's hope that they were on their way to the cavern of the island faded. The current grew swifter, and he had to fight to keep his head above water, his tired body reacting sluggishly to commands. The murmur of the racing flood drummed louder in his ears, or was that sound the same? He could no longer be sure. Shann only knew that it was close to impossible to snatch the necessary breath as he was rolled over and over in the hurrying flood. In the end he was ejected into blazing, blinding light, into a suffocation of wild water as the bullet in an ancient Terran rifle might have been fired at no specific target. Gasping, beaten, more than half-drowned, Shann was pummeled by waves, literally driven up on a rocky surface which skinned his body cruelly. He lay there, his arms moving feebly until he contrived to raise himself in time to be wretchedly sick. Somehow he crawled on a few feet farther before he subsided again, blinded by the light, flinching from the heat of the rocks on which he lay, but unable to do more for himself.
