“They go to war upon Those Others. He who guided us here knows also that the new knowledge they have brought into the city is danger. If an end is not put to it before they can use it, then”—he shrugged—“the mermen must retreat into the depths. And we, who can not follow them—” He made a quick, thrusting gesture as if using a knife on his own throat. “For a time Those Others have been growing fewer in number and weaker. Their children are not many and sometimes there are years when none are born at all. And they have forgotten so much. But now, perhaps they can increase once more, not only in wisdom and strength of arms, but in numbers. The mermen have kept a watch on them, content to let matters rest, sure that time would defeat them. But now, time no longer fights on our side.”
Raf watched the furred people with their short spears, their knives. He recalled that rocky island where the aliens had unleashed the fire. The expeditionary force would not have a chance against that.
“But your weapons would.” The words addressed to him were clear, though they had not been spoken aloud. Raf’s hand went to the pocket where two more of the blast bombs rested. “And this is your battle as much as ours!”
But it wasn’t his fight! Dalgard had gone too far with that suggestion. Raf had no ties on this world, the RS 10 was waiting to take him away. It was strictly against all orders, all his training, for him to become involved in alien warfare. The pilot’s hand went back to his belt. He was not going to allow himself to be pushed onto anything foolish, whether this “colonist” could read his mind or not.
The first ranks of the mermen had already waded past them, heading into the way down which the escaping prisoners had come. To Raf’s eyes none of them paid any attention to the two humans as they went, though they were probably in mental touch with his companion.
“You are already termed one of us in their eyes,” Dalgard was careful to use oral speech this time. “When you came to our rescue in the arena they believed that you were of our kind. Do you think you can return to walk safely through the city? So”—he drew a hissing breath of surprise when the thought which leaped into Raf’s mind was plain to Dalgard also—“you have—there are more of you there! But already Those Others may be moving against them because of what you have done!”
Raf who had been about to join the mermen stopped short. That aspect had not struck him before. What had happened to Soriki and the flitter, to the captain and Lablet, who had been in the heart of the enemy territory when he had challenged the aliens? It would be only logical that the painted people would consider them all dangerous now. He must get out of here, back to the flitter, try to help where unwittingly he had harmed—
Dalgard caught up with him. He had been able to read a little of what had passed through the other’s mind. Though it was difficult to sort order out of the tangled thoughts. The longer he was with the stranger, the more aware he became of the differences between them. Outwardly they might appear of the same species, but inwardly—Dalgard frowned—there was something that he must consider later, when they had a thinking space. But now he could understand the other’s agitation. It was very true that Those Others might turn on the stranger’s fellows in retaliation for his deeds.
Together they joined the mermen. There was no talk, nothing to break the splashing sound of bodies moving against the current. As they pressed on, Raf was sure that this was not the same way they had come. And once more Dalgard answered his unspoken question.
“We seek another door into the city, one long known to these tribesmen.”
Raf would gladly have run, but he could not move faster than his guides, and while their pace seemed deliberate, they did not pause to rest. The whole city, he decided, must be honeycombed with these drains. After traversing a fourth tunnel, they climbed out of the flood onto a dry passage, which wormed along, almost turning on itself at times.
Side passages ran out from this corridor like rootlets from a parent root, and small parties of mermen broke from the regiment to follow certain ones, leaving without orders or farewells. At the fifth of these Dalgard touched Raf’s arm and drew him aside.
“This is our way.” Tensely the scout waited. If the stranger refused, then the one plan the scout had formed during the past half-hour would fail. He still held to the hope that Raf, with what Raf carried, could succeed in the only project which would mean, perhaps not his safety nor the safety of the tribe he now marched among, but the eventual safety of Astra itself, the safety of all the harmless people of the sea, the little creatures of the grass and the sky, of his own land at Homeport. He would have to force Raf into action if need be. He did not use the mind touch; he knew now the unspoken resentment which followed that. If it became necessary—Dalgard’s hands balled into fists—he would strike down the stranger—take from him—Swiftly he turned his thoughts from that. It might be easy, now that he had established mental contact with this off-worlder, for the other to pick up a thought as vivid as that.
But luckily Raf obediently turned into the side passage with the six mermen who were to attack at this particular point. The way grew narrower until they crept on hands and knees between rough walls which were not of the same construction as the larger tunnels. The smaller mermen had no difficulty in getting through, but twice Raf’s equipment belt caught on projections and he had to fight his way free.
They crawled one by one into a ventilation shaft much like the one he had climbed at the Center. Dalgard’s whisper reached him.
“We are now in the building which houses their sky ship.”
“I know that one,” Raf returned almost eagerly, glad at last to be back so close to familiar territory. He climbed up the hand-and footholds the sea-monster lamp disclosed, wishing the mermen ahead would speed up.
The grille at the head of the shaft had been removed, and the invaders arose one by one into a dim and dusty place of motionless machinery, which, by all tangible evidence, had not been entered for some time. But the cautious manner in which the sea people strung out to approach the far door argued that the same might not be true beyond.
For the first time Raf noticed that his human companion now held one of the knives of the merpeople, and he drew his stun gun. But he could not forget the flame-throwers which might at that very moment be trained upon the other side of that door by the aliens. They might be walking into a trap.
He half expected one of those disconcerting thought answers from Dalgard. But the scout was playing safe—nothing must upset the stranger. Confronted by what had to be done, he might be influenced into acting for them. So Dalgard strode softly ahead, apparently not interested in Raf.
One of the mermen worked at the door, using the point of his spear as a lever. Here again was a vista of machinery. But these machines were alive; a faint hum came from their casings. The mermen scattered, taking cover, a move copied by the two humans.
The pilot remained in hiding, but he saw one of the furred people running on as light-footedly as a shadow. Then his arm drew back, and he cast his spear. Raf fancied he could hear a faint whistle as the weapon cut the air. There was a cry, and the merman ran on, vanishing into the shadows, to return a second or two later wiping stains from his weapon. Out of their places of concealment, his fellows gathered about him. And the humans followed.
Now they were fronted by a ramp leading up, and the mermen took it quickly, their bare, scaled feet setting up a whispering echo which was drowned by the clop of Raf’s boots. Once more the party was alert, ready for trouble, and taking his cue from them, he kept his stun gun in his hand.
But the maneuver at the head of the ramp surprised him. For, though he had heard no signal, all the party but one plastered their bodies back against the wall, Dalgard pulling Raf into position beside him, the scout’s muscular bare arm pinning the pilot into a narrow space. One merman stood at the crack of the door at the top of the ramp. He pushed the barrier open and crept in.
Meanwhile those who waited poised their spears, all aimed at that door. Raf fingered the button on his gun to “spray” as he had when he had faced the attack of the scavengers in the arena tunnels.
