The clak-claks screamed and dived about him, highly resentful of his intrusion. And when they grew so bold as to buffet him with their wings, threaten him with their tearing beaks, he was glad to reach the broken rock edging his chosen door and duck inside. Once there, Shann looked back. There was no sighting the cliff window where Thorvald stood, nor was he aware in any way of mental contact with the Survey officer; their hope of such a linkage might be futile.
Shann was reluctant to venture farther. His eyes had sufficiently adjusted to the limited supply of light, and now the Terran brought out the one aid the Wyverns had granted him, a green crystal such as those which had played the role of stars on the cavern roof. He clipped its simple loop setting to the front of his belt, leaving his hands free. Then, having filled his lungs for the last time with clean, sea-washed air, he started into the dome of the skull.
There was a fetid thickness to this air only a few feet away from the outer world. The odor of clak-clak droppings and refuse from their nests was strong, but there was an added staleness, as if no breeze ever scooped out the old atmosphere to replace it with new. Fragile bones crunched under Shann’s boots, but as he drew away from the entrance, the pale glow of the crystal increased its radiance, emitting a light not unlike that of the phosphorescent bushes, so that he was not swallowed up by dark.
The cave behind the nose hole narrowed quickly into a cleft, a narrow cleft which pierced into the bowl of the skull. Shann proceeded with caution, pausing every few steps. There came a murmur rising now and again to a shriek, issuing, he guessed, from the clak-clak rookery above. And the pound of sea waves was also a vibration carrying through the rock. He was listening for something else, at the same time testing the ill-smelling air for that betraying muskiness which spelled Throg.
When a twist in the narrow passage cut off the splotch of daylight, Shann drew his stunner. The strongest bolt from that could not jolt a Throg into complete paralysis, but it would slow up any attack.
Red—pinpoints of red—were edging a break in the rock wall. They were gone in a flash. Eyes? Perhaps of the rock dwellers which the Wyverns hated? More red dots, farther ahead. Shann listened for a sound he could identify.
But smell came before sound. That trace of effluvia which in force could sicken a Terran, was his guide. The cleft ended in a space to which the limited gleam of the crystal could not provide a far wall. But that faint light did show him his quarry.
The Throg was not on his feet, ready for trouble, but hunched close to the wall. And the alien did not move at Shann’s coming. Did the beetle-head sight him? Shann wondered. He moved cautiously. And the round head, with its bulbous eyes, turned a fraction; the mandibles about the ugly mouth opening quivered. Yes, the Throg could see him.
But still the alien made no move to rise out of his crouch, to come at the Terran. Then Shann saw the fall of rock, the stone which pinned a double-kneed leg to the floor. And in a circle about the prisoner were the small, crushed, furred things which had come to prey on the helpless to be slain themselves by the well-aimed stones which were the Throg’s only weapons of defense.
Shann sheathed his stunner. It was plain the Throg was helpless and could not reach him. He tried to concentrate mentally on a picture of the scene before him, hoping that Thorvald or one of the Wyverns could pick it up. There was no answer, no direction. Choice of action remained solely his.
The Terran made the oldest friendly gesture of his kind; his empty hands held up, palm out. There was no answering move from the Throg. Neither of the other’s upper limbs stirred, their claws still gripping the small rocks in readiness for throwing. All Shann’s knowledge of the alien’s history argued against an unarmed advance. The Throg’s marksmanship, as borne out by the circle of small bodies, was excellent. And one of those rocks might well thud against his own head, with fatal results. Yet he had been sent there to get the Throg free and out of Wyvern territory.
So rank was the beetle smell of the other that Shann coughed. What he needed now was the aid of the wolverines, a diversion to keep the alien busy. But this time there was no disk working to produce Taggi and Togi out of thin air. And he could not continue to just stand there staring at the Throg. There remained the stunner. Life on the Dumps tended to make a man a fast draw, a matter of survival for the fastest and most accurate marksman. And now one of Shann’s hands swept down with a speed which, learned early, was never really to be forgotten.
He had the rod out and was spraying on tight beam straight at the Throg’s head before the first stone struck his shoulder and his weapon fell from a numbed hand. But a second stone tumbled out of the Throg’s claw. The alien tried to reach for it, his movements slow, uncertain.
Shann, his arm dangling, went in fast, bracing his good shoulder against the boulder which pinned the Throg. The alien aimed a blow at the Terran’s head, but again so slowly Shann had no difficulty in evading it. The boulder gave, rolled, and Shann cleared out of range, back to the opening of the cleft, pausing only to scoop up his stunner.
For a long moment the Throg made no move; his dazed wits must have been working at very slow speed. Then the alien heaved up his body to stand erect, favoring the
