Shann fought an attack of giddiness. It would be very easy to lose control, to tumble over and be swallowed up in what might well be a bottomless chasm. And what was the purpose of this well? Was it a trap to entice a prisoner into an unwary climb and then let gravity drag him over? The whole setup was meaningless. Perhaps meaningless only to him, Shann conceded, with a flash of level thinking. The situation could be quite different as far as the natives were concerned. This structure did have a reason, or it would never have been erected in the first place.
"What"s the matter?" Thorvald"s voice was rough with impatience.
"This thing"s a well." Shann edged about a fraction to call back. "The inside is open and--as far as I can tell--goes clear to the planet"s core."
"Ladder on the inside too?"
Shann squirmed. That was, of course, a very obvious supposition. He kept a tight hold with his left hand, and with the other, he did some exploring. Yes, here was a hollow right enough, twin to those on the outside. But to swing over that narrow edge of safety and begin a descent into the black of the well was far harder than any action he had taken since the morning the Throgs had raided the camp. The green mist could hold no terrors greater than those with which his imagination peopled the depths now waiting to engulf him. But Shann swung over, fitted his boot into the first hollow, and started down.
The only encouragement he gained during that nightmare ordeal was that those holes were regularly s.p.a.ced. But somehow his confidence did not feed on that fact. There always remained the nagging fear that when he searched for the next it would not be there and he would cling to his perch lacking the needful strength in aching arms and legs to reclimb the inside ladder.
He was fast losing that sense of well being which had been his during his travels through the fog; a fatigue tugged at his arms and weighed leaden on his shoulders. Mechanically he prospected for the next hold, and then the next. Above, the oblong of half-light grew smaller and smaller, sometimes half blotted out by the movements of Thorvald"s body as the other followed him down that interior way.
How far _was_ down? Shann giggled lightheadedly at the humor of that, or what seemed to be humor at the moment. He was certain that they were now below the level of the sand floor outside the slab. And yet no end had come to the well hollow.
No break of light down here; he might have been sightless. But just as the blind develop an extra perceptive sense of unseen obstacles, so did Shann now find that he was aware of a change in the nature of the s.p.a.ce about him. His weary arms and legs held him against the solidity of a wall, yet the impression that there was no longer another wall at his back grew stronger with every niche which swung him downward. And he was as sure as if he could see it, that he was now in a wide-open s.p.a.ce, another cavern; perhaps, but this one totally dark.
Deprived of sight, he relied upon his ears. And there was a sound, faint, distorted perhaps by the acoustics of this place, but keeping up a continuous murmur. Water! Not the wash of waves with their persistent beat, but rather the rippling of a running stream. Water must lie below!
And just as his weariness had grown with his leaving behind the fog, so now did both hunger and thirst gnaw at Shann, all the sharper for the delay. The Terran wanted to reach that water, could picture it in his mind, putting away the possibility--the probability--that it might be sea-born and salt, and so unfit to drink.
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 cl.u.s.ters 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 s.n.a.t.c.h 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.
His first coherent thought was that his speculation concerning the reality of this experience was at last resolved. This could not possibly be an hallucination; at least this particular sequence of events was not. And he was still hazily considering that when a hand fell on his shoulder, fingers biting into his raw flesh.
Shann snarled, rolled over on his side. Thorvald, water dripping from his rags--or rather steaming from them--his s.h.a.ggy hair plastered to his skull, sat there.
"You all right?"
Shann sat up in turn, shielding his smarting eyes. He was bruised, battered badly enough, but he could claim no major injuries.
"I think so. Where are we?"
Thorvald"s lips stretched across his teeth in what was more a grimace than a smile. "Right off the map, any map I know. Take a look."
They were on a sc.r.a.p of beach--beach which was more like a reef, for it lacked any covering comparable to sand except for some cupfuls of coa.r.s.e gravel locked in rock depressions. Rocks, red as the rust of dried blood, rose in fantastic water-sculptured shapes around the small semi-level s.p.a.ce they had somehow won.
This s.p.a.ce was V-shaped, washed by equal streams on either side of the p.r.o.ng of rock by water which spouted from the face of a sheer cliff not too far away, with force enough to spray several feet beyond its exit point. Shann seeing that and guessing at its significance, drew a deep breath, and heard the ghost of an answering chuckle from his companion.
"Yes, that"s where we came out, boy. Like to make a return trip?"
Shann shook his head, and then wished that he had not so rashly made that move, for the world swung in a dizzy whirl. Things had happened too fast. For the moment it was enough that they were out of the underground ways, back under the amber sky, feeling the bite of Warlock"s sun.
Steadying his head with both hands, Shann turned slowly, to survey what might lie at their backs. The water, pouring by on either side, suggested that they were again on an island. Warlock, he thought gloomily, seemed to be for Terrans a succession of islands, all hard to escape.
The tangle of rocks did not encourage any exploration. Just gazing at them added to his weariness. They rose, tier by tier, to a ragged crown against the sky. Shann continued to sit staring at them.
"To climb that...." His voice trailed into the silence of complete discouragement.
"You climb--or swim," Thorvald stated. But, Shann noted, the Survey officer was not in a hurry to make either move.
Nowhere in that wilderness of rock was there the least relieving bit of purple foliage. Nor did any clak-claks or leather-headed birds tour the sky over their heads. Shann"s thirst might have been partially a.s.suaged, but his hunger remained. And it was that need which forced him at last into action. The barren heights promised nothing in the way of food, but remembering the harvest the wolverines had taken from under the rocks along the river, he got to his feet and lurched out on the reef which had been their salvation, hunting some pool which might hold an edible captive or two.
So it was that Shann made the discovery of a possible path consisting of a ledge running toward the other end of the island, if this were an island where they had taken refuge. The spray of the water drenched that way, feeding small pools in the uneven surface, and strips of yellow weed trailed in slimy ribbons back below the surface of the waves.
He called to Thorvald and gestured to his find. And then, close together, linking hands when the going became hazardous, the men followed the path. Twice they made finds in the pools, finned or clawed grotesque creatures, which they killed and ate, wolfing down the few fragments of odd-tasting flesh. Then, in a small crevice, which could hardly be dignified by the designation of "cave," Thorvald chanced upon a quite exciting discovery--a clutch of four greenish eggs, each as large as his doubled fist.
Their outer covering was more like tough membrane than true sh.e.l.l, and the Terrans worried it open with difficulty. Shann shut his eyes, trying not to think of what he mouthed as he sucked his share dry. At least that semi-liquid stayed put in his middle, though he expected disastrous results from the experiment.
More than a little heartened by this piece of luck, they kept on, though the ledge changed from a reasonably level surface to a series of rising, unequal steps, drawing them away from the water. At long last they came to the end of that path. Shann leaned back against a convenient spur of rock.
"Company!" he alerted Thorvald.
The Survey officer joined him to share an outcrop of rock from which they were provided with an excellent view of the scene below, and it was a scene to hold their full attention.
That soft sweep of sand which had floored the cavern of the fog lay here also, a gray-blue carpet sloping gently out of the sea. For Shann had no doubt that the wide stretch of water before them was the western ocean.
Walling the beach on either side, and extending well out into the water so that the farthest piles were awash except for their crowns, were pillars of stone, shaped with the same finish as that slab which had provided them a ladder of escape. And because of the regularity of their s.p.a.cing, Shann did not believe them works of nature.
Grouped between them now were the players of the drama. One of the Warlockian witches, her gem body patterns glittering in the sunlight, was walking backward out of the sea, her hands held palms together, breast high, in a Terran att.i.tude of prayer. And following her something swam in the water, clearly not another of her own species. But her actions suggested that by some invisible means she was drawing that water dweller after her. Waiting on sh.o.r.e were two others of her kind, viewing her actions with close attention, the attention of scholars for an instructor.
"Wyverns!"
Shann looked inquiringly at his companion. Thorvald added a whisper of explanation. "A legend of Terra--they were supposed to have a snake"s tail instead of hind legs, but the heads.... They"re Wyverns!"
Wyverns. Shann liked the sound of that word; to his mind it well fitted the Warlockian witches. And the one they were watching in action continued her steady backward retreat, rolling her bemused captive out of the water. What emerged into the blaze of sunlight was one of those fork-tailed sea dwellers such as the Terrans had seen die after the storm. The thing crawled out of the shallows, its eyes focused in a blind stare on the praying hands of the Wyvern.
She halted, well up on the sand, when the body of her victim or prisoner--Shann was certain that the fork-tail was one or the other--was completely out of the water. Then, with lightning speed, she dropped her hands.
Instantly fork-tail came to life. Fanged jaws snapped. Aroused, the beast was the incarnation of evil rage, a rage which had a measure of intelligence to direct it into deadly action. And facing it, seemingly unarmed and defenseless, were the slender, fragile Wyverns.
Yet none of the small group of natives made any attempt to escape. Shann thought them suicidal in their indifference as fork-tail, short legs sending the fine sand flying in a dust cloud, made a rush toward its enemies.
