It was in the underground that he made his first important find. They had seen ground vehicles in the city, a few still in operation, but Raf had gathered that the fuel and extra parts for the machines were now so scarce that they were only used in emergencies. Here, however, was a means of transportation quite different, a tunnel through which ran a ribbon of belt, wide enough to accommodate three or four pa.s.sengers at once. It did not move, but when Raf dared to step out upon its surface, it swung under his weight. Since it ran in the general direction of the Center he decided to use it. It trembled under his tread, but he found that he could run along it making no sound.

The tunnel was not in darkness, for square plates set in the roof gave a diffused violet light. However, not too far ahead, the light was brighter, and it came from one side, not the roof. Another station on this abandoned way? The pilot approached it with caution. If his b.u.mp of direction was not altogether off, this must be either below the Center or very close to it.

The second station proved to be a junction where more than one of the elastic paths met. Though he crouched to listen for a long moment before venturing out into that open s.p.a.ce, he could hear or see nothing which suggested that the aliens ever came down now to these levels.

They had provided an upward ramp, and Raf climbed it, only to meet his first defeat at its top. For here was no opening to admit him to the ground floor of what he hoped was the Center. Baffled by the smooth surface over which he vainly ran his hands seeking for some clue to the door, he decided that the aliens had, for some purpose of their own, walled off the lower regions. Discouraged, he returned to the junction level. But he was not content to surrender his plans so easily. Slowly he made a circuit of the platform, examining the walls and celling. He found an air shaft, a wide opening striking up into the heart of the building above.

It was covered with a grille and it was above his reach but....

Raf measured distances and planned his effort. The mouth of a junction tunnel ran less than two feet away from that grille. The opening was outlined with a ledge, which made a complete arch from the floor. He stopped and triggered the gravity plates in his s.p.a.ce boots. Made to give freedom of action when the ship was in free fall, they might just provide a weak suction here. And they did! He was able to climb that arch and, standing on it, work loose the grille which had been fashioned to open. Now....

The pilot flashed his hand torch up into that dark well. He had been right--and lucky! There were holds at regular intervals, something must have been serviced by workmen in here. This was going to be easy.

His fingers found the first hold, and he wormed his way into the shaft.

It was not a difficult climb, for there were niches along the way where the alien mechanics who had once made repairs had either rested or done some of their work. And there were also grilles on each level which gave him at least a partial view of what lay beyond.

His guess was right; he recognized the main hall of the Center as he climbed past the grid there, heading up toward those levels where he was sure the leaders of the aliens had their private quarters. Twice he paused to look in upon conferences of the gaudily wrapped and painted civilians, but, since he could not understand what they were saying, it was a waste of time to linger.

He was some eight floors up when chance, luck, or that mysterious something which had brought him into this venture, led him to the right place at the right time. There was one of those niches, and he had just settled into it, peering out through the grid, when he saw the door at the opposite end of the room open and in marched a party of warriors with a prisoner in their midst.

Raf's eyes went wide. It was the captive he sought; he had no doubt of that. But who--what--was that prisoner?

This was no fur-covered half-animal, nor was it one of the delicate-boned, decadent, painted creatures such as those who now ringed in their captive. Though the man had been roughly handled and now reeled rather than walked, Raf thought for one wild instant that it was one of the crew from the s.p.a.cer. The light hair, showing rings of curl, the tanned face which, beneath dirt and bruises, displayed a very familiar cast of features, the body hardly covered by rags of clothing--they were all so like those of his own kind that his mind at first refused to believe that this was _not_ someone he knew. Yet as the party moved toward his hiding place he knew that he was facing a total stranger.

Stranger or no, Raf was sure that he saw a Terran. Had another ship made a landing on this planet? One of those earlier ships whose fate had been a mystery on their home world? Who--and when--and why? He huddled as close to the grid as he could get, alert to the slightest movement below as the prisoner faced his captors.

ARENA

The dull pain which throbbed through Dalgard's skull with every beat of his heart was confusing, and it was hard to think clearly. But the colony scout, soon after he had fought his way back to consciousness, had learned that he was imprisoned somewhere in the globe ship. Just as he now knew that he had been brought across the sea from the continent on which Homeport was situated and that he had no hope of rescue.

He had seen little of his captors, and the guards, who had hustled him from one place of imprisonment to another, had not spoken to him, nor had he tried to communicate with them. At first he had been too sick and confused, then too wary. These were clearly Those Others and the conditioning which had surrounded him from birth had instilled in him a deep distrust of the former masters of Astra.

Now Dalgard was more alert, and his being brought to this room in what was certainly the center of the alien civilization made him believe that he was about to meet the rulers of the enemy. So he stared curiously about him as the guards jostled him through the door.

On a dais fashioned of heaped-up rainbow-colored pads were three aliens, their legs folded under them at what seemed impossible angles.

One wore the black wrappings, the breastplate of the guards, but the other two had indulged their love of color in weird, eye-disturbing combinations of shades in the bandages wrapping the thin limbs and paunchy bodies. They were, as far as he could see through the thick layers of paint overlaying their skins, older than their officer companion. But nothing in their att.i.tude suggested that age had mellowed them.

Dalgard was brought to stand before the trio as before a tribunal of judges. His sword-knife had been taken from his belt before he had regained his senses, his hands were twisted behind his back and locked together in a bar and hoop arrangement. He certainly could offer little threat to the company, yet they ringed him in, weapons ready, watching his every move. The scout licked cracked lips. There was one thing they could not control, could not prevent him from doing.

Somewhere, not too far away, was help ...

Not from the merpeople, but he was sure that he had been in contact with another friendly mind. Since the hour of his awakening on board the globe ship, when he had half-consciously sent out an appeal for aid over the band which united him with Sssuri's race, and had touched that other consciousness--not the cold alien stream about him--he had been sure that somewhere within the enemy throng there was a potential savior. Was it among those who manned the strange flyer, those the merpeople had spied upon but whom he had not yet seen?

Dalgard had striven since that moment of contact to keep in touch with the nebulous other mind, to project his need for help. But he had been unable to enter in freely as he could with his own kind, or with Sssuri and the sea people. Now, even as he stood in the heart of the enemy territory completely at the mercy of the aliens, he felt, more strongly than ever before, that another, whose mind he could not enter and yet who was in some queer way sensitive to his appeal, was close at hand. He searched the painted faces before him trying to probe behind each locked mask, but he was certain that the one he sought was not there. Only--he must be! The contact was so strong--Dalgard's startled eyes went to the wall behind the dais, tried vainly to trace what could only be felt. He would be willing to give a knife oath that the stranger was within seeing, listening distance at this minute!

While he was so engrossed in his own problem, the guard had moved. The hooped bar which locked his wrists was loosened, and his arms, each tight in the grip of one of the warriors were brought out before him.

The officer on the dais tossed a metal ring to one of the guards.

Roughly the warrior holding Dalgard's left arm forced the band over his hand and jerked it up his forearm as far as it would go. As it winked in the light the scout was reminded of a similar bracelet he had seen--where? On the front leg of the snake-devil he had shot!

The officer produced a second ring, slipping it smoothly over his own arm, adjusting it to touch bare skin and not the wrappings which served him as a sleeve. Dalgard thought he understood. A device to facilitate communication. And straightway he was wary. When his ancestors had first met the merpeople, they had established a means of speech through touch, the palm of one resting against the palm of the other. In later generations, when they had developed their new senses, physical contact had not been necessary. However, here--Dalgard's eyes narrowed, the line along his jaw was hard.

He had always accepted the merpeople's estimate of Those Others, that their ancient enemies were all-seeing and all-knowing, with mental powers far beyond their own definition or description. Now he half expected to be ruthlessly mind-invaded, stripped of everything the enemy desired to know.

So he was astonished when the words which formed in his thoughts were simple, almost childish. And while he prepared to answer them, another part of him watched and listened, waiting for the attack he was sure would come.

"You--are--who--what?"

He forced a look of astonishment. Nor did he make the mistake of answering that mentally. If Those Others did not know he could use the mind speech, why betray his power?

"I am of the stars," he answered slowly, aloud, using the speech of Homeport. He had so little occasion to talk lately that his voice sounded curiously rusty and harsh in his own ears. Nor had he the least idea of the impression those few archaically accented words would have on one who heard them.

To Dalgard's inner surprise the answer did not astonish his interrogator. The alien officer might well have been expecting to hear just that. But he pulled off his own arm band before he turned to his fellows with a spurt of the twittering speech they used among themselves. While the two civilians were still trilling, the officer edged forward an inch or so and stared at Dalgard intently as he replaced the band.

"You not look--same--as others--"

"I do not know what you mean. Here are not others like me."

One of the civilians twitched at the officer's sleeve, apparently demanding a translation, but the other shook him off impatiently.

"You come from sky--now?"

Dalgard shook his head, then realized that gesture might not mean anything to his audience. "Long ago before I was, my people came."

The alien digested that, then again took off his band before he relayed it to his companions. The excited twitter of their speech scaled up.

"You travel with the beasts--" the alien's accusation came crisply while the others gabbled. "That which hunts could not have tracked you had not the stink of the beast things been on you."

"I know no beasts," Dalgard faced up to that squarely. "The sea people are my friends!"

It was hard to read any emotion on these lacquered and bedaubed faces, but before the officer once more broke bracelet contact, Dalgard did sense the other's almost hysterical aversion. The scout might just have admitted to the most revolting practices as far as the alien was concerned. After he had translated, all three of those on the dais were silent. Even the guards edged away from the captive as if in some manner they might be defiled by proximity. One of the civilians made an emphatic statement, got creakily to his feet, and walked always as if he would have nothing more to do with this matter. After a second or two of hesitation his fellow followed his example.

The officer turned the bracelet around in his fingers, his dark eyes with their slitted pupils never leaving Dalgard's face. Then he came to a decision. He pushed the ring up his arm, and the words which reached the prisoner were coldly remote, as if the captive were no longer judged an intelligent living creature but something which had no right of existence in a well-ordered universe.

"Beast friends with beast. As the beasts--so shall you end. It is spoken."

One of the guards tore the bracelet from Dalgard's arm, trying not to touch the scout's flesh in the process. And those who once more shackled his wrists ostentatiously wiped their hands up and down the wrappings on their thighs afterwards.

But before they jabbed him into movement with the muzzles of their weapons, Dalgard located at last the source of that disturbing mental touch, not only located it, but in some manner broke through the existing barrier between the strange mind and his and communicated as clearly with it as he might have with Sssuri. And the excitement of his discovery almost led to self-betrayal!

Terran! One of those who traveled with the aliens? Yet he read clearly the other's distrust of that company, the fact that he lay in concealment here without their knowledge. And he was not unfriendly--surely he could not be a Peaceman of Pax! Another fugitive from a newly-come colony ship--? Dalgard beamed a warning to the other. If he who was free could only reach the merpeople! It might mean the turning point in their whole venture!

Dalgard was furiously planning, simplifying, trying to impress the most imperative message on that other mind as he stumbled away in the midst of the guards. The stranger was confused, apparently Dalgard's arrival, his use of the mind touch, had been an overwhelming surprise.
