For a long moment he could only cling to the rock which had saved him, retching and dazed, as the water washed about his body, a current tugging at his trailing legs. There was light of a sort here, patches of green which glowed with the same subdued light as the bushes of the outer world, for he was no longer under the night sky. A rock-roof was but inches over his head; he must be in some cave or tunnel under the surface of the sea. Again a gust of panic shook him as he felt trapped. The water continued to pull at Shann, and in his weakened condition it was a temptation to yield to that pull; the more he fought it the more he was exhausted. At last the Terran turned on his back, trying to float with the stream, sure he could no longer battle it. Luckily those few inches of space above the surface of the water continued, and he had air to breathe. But the fear of that ending, of being swept under the surface, chewed at his nerves. And his bodily danger burned away the last of the spell which had held him, brought him into this place, wherever it might be. Was it only his heightened imagination, or had the current grown swifter? Shann tried to gauge the speed of his passage by the way the patches of green light slipped by. Now he turned and began to swim slowly, feeling as if his arms were leaden weights, his ribs a cage to bind his aching lungs. Another patch of light ... larger ... spreading across the roof over head. Then, he was out! Out of the tunnel into a cavern so vast that its arching roof was like a skydome far above his head. But here the patches of light were brighter, and they were arranged in odd groups which had a familiar look to them. Only, better than freedom overhead, there was a shore not too distant. Shann swam for that haven, summoning up the last rags of his strength, knowing that if he could not reach it very soon he was finished. Somehow he made it and lay gasping, his cheek resting on sand finer than any of the outer world, his fingers digging into it for purchase to drag his body on. But when he collapsed, his legs were still awash in water. No footfall could be heard on that sand. But he knew that he was no longer alone. He braced his hands and with painful effort levered up his body. Somehow he made it to his knees, but he could not stand. Instead he half tumbled back, so that he faced them from a sitting position. _Them_--there were three of them--the dragon-headed ones with their slender, jewel-set bodies glittering even in this subdued light, their yellow eyes fastened on him with a remoteness which did not approach any human emotion, save perhaps that of a cold and limited wonder. But behind them came a fourth, one he knew by the patterns on her body.
