And when he met nothing menacing, Shann began to relax. His heart no longer labored; he made no move to draw the stunner or knife. Where he was and for what purpose, he had no idea. But there _was_ a purpose in this and that the Warlockians were behind it, he did not doubt. The "initiates' road," the leader had said, and the conviction was steady in his mind that he faced some test of alien devising. A cavern with a green veil--his memory awoke. Thorvald's dream! Shann paused, trying to remember how the other had described this place. So he was enacting Thorvald's dream! And could the Survey officer now be caught in Shann's dream in turn, climbing up somewhere into the nose slit of a skull-shaped mountain? Green fog without end, and Shann lost in it. How long had he been here? Shann tried to reckon time, the time since his coming into the water-world of the starred cavern. He realized that he had not eaten, nor drank, nor desired to do so either--nor did he now. Yet he was not weak; in fact, he had never felt such tireless energy as possessed his spare body. Was this _all_ a dream? His threatened drowning in the underground stream a nightmare? Yet there was a pattern in this, just as there had been a pattern in the needles he had spilled across the table. One even led to another with discernible logic; because he had tossed that particular pattern he had come here. According to the ambiguous instructions or warnings of the Warlockian witch, his safety in this place would depend upon his ability to tell true dreams from false. But how ... why? So far he had done nothing except walk through a green fog, and for all he knew, he might well be traveling in circles. Because there was nothing else to do, Shann walked on, his boots pressing sand, rising from each step with a small sucking sound. Then, as he stooped to search for some indication of a path or road which might guide him, his ears caught the slightest of noises--other small sucking whispers. He was not the only wayfarer in this place! 13. HE WHO DREAMS.... The mist was not a quiet thing; it billowed and curled until it appeared to half-conceal darker shadows, any one of which could be an enemy. Shann remained hunkered on the sand, every sense abnormally alert, watching the fog. He was still sure he could hear sounds which marked the progress of another. What other? One of the Warlockians tracking him to spy? Or was there some prisoner like himself lost out there in the murk? Could it be Thorvald? Now the sound had ceased. He was not even sure from what direction it had first come. Perhaps that other was listening now, as intent upon locating him. Shann ran his tongue over dry lips. The impulse to call out, to try and contact any fellow traveler here, was strong. Only hard-learned caution kept him silent. He got to his hands and knees, uncertain as to his previous direction.
