She held out her hands and Shann saw now, lying on a slowly closing palm, a disk such as the one Thorvald had shown him. The Terran had only one moment of fear and then came blackness, more absolute than the dark of any night he had ever known.
Light once more, green light with an odd shimmering quality to it. The skull-lined walls were gone; there were no walls, no building held him. Shann strode forward, and his boots sank in sand, that smooth, satin sand which had ringed the island in the cavern. But he was certain he was no longer on that island, even within that cavern, though far above him there was still a dome of roof.
The source of the green shimmer lay to his left. Somehow he found himself reluctant to turn and face it. That would commit him to action. But Shann turned.
A veil, a veil of rippling green. Material? No, rather mist or light. A veil depending from some source so far over his head that its origin was hidden in the upper gloom, a veil which was a barrier he must cross.
With every nerve protesting, Shann walked forward, unable to keep back. He flung up his arm to protect his face as he marched into that stuff. It was warm, and the gas—if gas it was—left no slick of moisture on his skin in spite of its foggy consistency. And it was no veil or curtain, for although he was already well into the murk, he saw no end to it. Blindly he trudged on, unable to sight anything but the rolling billows of green, pausing now and again to go down on one knee and pat the sand underfoot, reassured at the reality of that footing.
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!

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.
Shann crept. Someone expecting a man walking erect might be suitably distracted by the arrival of a half-seen figure on all fours. He halted again to listen.
He had been right! The sound of a very muffled footfall or footfalls, carried to his ears. He was sure that the sound was louder, that the unknown was approaching. Shann stood, his hand close to his stunner. He was almost tempted to spray that beam blindly before him, hoping to hit the unseen by chance.
A shadow—something more swift than a shadow, more than one of the tricks the curling fog played on eyes—was moving with purpose and straight for him. Still, prudence restrained Shann from calling out.
The figure grew clearer. A Terran! It could be Thorvald! But remembering how they had last parted, Shann did not hurry to meet him.
That shadow-shape stretched out a long arm in a sweep as if to pull aside some of the vapor concealing them from each
