Kirk thought fast. "Very well. Get everybody else on board the ship. The fewer people we have breathing the air, the longer the rest of us can hold out. How long is that, Scotty?"
"It's got naught to do with the air, Captain. The reactor will go supercritical in about ten hours. You'll have to find your beastie well before then."
"Right. Feed us constant status reports, Scotty. Mr. Vanderberg, you and your men assemble on level twenty-three, checkpoint Tiger. There you'll team up with
Enterprise
security personnel. They're better armed than you are, so stay in sight of one of them at all times—buddy system. Mr. Spock and I will control all operations by communicator. Understood—and agreed?"
"Both," Vanderberg's voice said grimly. "Suicide is no part of my plans."
"Good. Kirk out . . . Mr. Spock, you seem to have picked up something."
"Yes, Captain. The creature is now quiescent a few thousand yards from here, in that direction."
Kirk took a quick look at his chart. "The map says these two tunnels converge there. Take the left one, Mr. Spock. I'll go to the right."
"Should we separate?"
"Two tunnels," Kirk said. "Two of us. We separate."
"Very well, Captain," Spock said, but his voice was more than a little dubious. But it couldn't be helped. Kirk moved down the right-hand tunnel, slowly and tensely.
The tunnel turned, and Kirk found himself in a small chamber, streaked with bright strata quite unlike the rest of the rock around him. Imbedded in there were dozens of round objects like the one Vanderberg had on his desk, or the one which had so fascinated Spock. He lifted his communicator again. "Mr. Spock."
"Yes, Captain."
"I've found a whole layer of those silicon nodules of yours."
"Indeed, Captain. Most illuminating. Captain—be absolutely certain you do not damage any of them."
"Explain."
"It is only a theory, Captain, but . . ." His voice was drowned out by the roar of hundreds of tons of collapsing rock and debris. Kirk threw himself against the wall, choking clouds of dust rising around him. When he could see again, it was evident that the roof of the tunnel had fallen across the way he had just come.
"Captain! Are you all right? Captain!"
"Yes, Mr. Spock. Quite all right. But we seem to have had a cave-in."
"I can phaser you out," Spock's voice said. "No, any disturbance would bring the rest of the wall down. Anyway, it isn't necessary. The chart said our tunnels meet further on. I can just walk out."
"Very well. But I find it disquieting that your roof chose to collapse at that moment. Please proceed with extreme caution. I shall double my pace."
"Very well, Mr. Spock. I'll meet you at the end of the tunnel. Kirk out."
As he tucked the communicator away, there came from behind him a sound as of pebbles being shaken in a can.
He spun instantly, but it was too late. The way was blocked.
It was his first clear sight of the creature, which was reared in the center of the tunnel. It was huge, shaggy, multicolored, and knobby with objects which might have been heads, sense organs, hands—Kirk could not tell. It was quivering gently, still making that strange noise.
Kirk whipped up his phaser. At once the creature shuffled backward. Was it now afraid of just one gun? He raised the weapon again, but this time the creature retreated no further. Neither did it advance.
Phaser at the ready, Kirk moved toward the animal, trying to get around it. At once, it moved to block him—not threateningly, as far as Kirk could tell, but just getting in his way.
Spock chose this moment to call him again. "Captain, a new reading shows the creature . . ."
"I know exactly where the creature is," Kirk said, his phaser steadily on it. "Standing about ten feet away from me."
"Kill it, Captain! Quickly!"
"It's—not making any threatening moves, Mr. Spock."
"You don't dare take the chance! Kill it!"
"I thought you were the one who wanted it kept alive," Kirk said, with grim amusement. "Captured, if possible."
"Your life is in danger, Captain. You can't take the risk."
"It seems to be waiting for something. I want to find out what. I'll shoot if I have to."
"Very well, Captain. I will hurry through my tunnel and approach it from the rear. I remind you that it is a proven killer. Spock out."
The creature was silent now. Kirk lowered his phaser a trifle, but there was no reaction.
"All right," Kirk said. "What do we do now? Talk it over?"
He really had not expected an answer, nor did he get one. He took a step forward and to one side. Again the creature moved to block him; and as it did, Kirk saw along one of its flanks a deep, ragged gouge, leaving a glistening, rocklike surface exposed. It was obviously a wound.
"Well, you can be hurt, can't you?" He lifted the phaser again. The creature rattled, and shrank back, but held its ground. Obviously it was afraid of the weapon, but it would not flee.
Kirk lowered the phaser, and the rattling stopped. Then he moved deliberately back against the nearest wall and dropped slowly into a squatting position, the phaser held loosely between his knees.
"All right. Your move. Or do we just sit and wait for something to happen?"
It was not a long wait. Almost at once, Spock burst into the area from the open end of the tunnel. He took in the situation instantly and his own phaser jerked up.
"Don't shoot!" Kirk shouted. Echoes went bounding away through the galleries and tunnels.
Spock looked from one to the other. As he did so, the creature moved slowly to the other side of the tunnel. Kirk guessed that he could get past it now before it could block him again. Instead, he said, "Come on over, Mr. Spock."
With the utmost caution, his highly interested eyes fastened on the creature, Spock moved to Kirk's side. He looked up at the walls in which the silicon nodules were imbedded. "Logical," he said.
"But what do they mean?"
"I'd rather not say just yet. If I could possibly get into Vulcan mind-lock with that creature—it would be easier if I could touch it . . ."
Before Kirk could even decide whether to veto this notion, Spock stepped toward the animal, his hand extended. It lurched back at once, its rattling loud and angry-sounding.
"Too bad," Spock said. "But obviously it will permit no contact. Well, then, I must do it the hard way. If you will be patient, Captain . . ."
Spock's eyes closed as he began to concentrate. The intense mental power he was summoning was almost physically visible. Kirk held his breath. The creature twitched nervously, uneasily.
Suddenly Spock's face contorted hi agony, and he screamed. "The pain! The pain!" With a great shudder, his face ashen, he began to fall; Kirk got to him just in time.
"Thank—you, Captain," Spock said, gasping and steadying himself. "I am sorry—but that is all I got. Just waves and waves of searing pain. Oh, and a name. It calls itself a Horta. It is in great agony because of the wound—but not reacting at all like a wounded animal."
Abruptly, the creature slithered forward to a smooth expanse of floor, and clung there for a moment. Then it moved away. Where it had been, etched into the floor in still smoking letters, were the words: NO KILL I. Both men stared at the sentence in astonishment.
" 'No kill I' "? Kirk said. "What's that? It could be a plea to us not to kill it—or a promise that it won't kill us."
"I don't know. It appears it learned more from me during our empathy than I did from it. But observe, Captain, that it thinks in vocables. That means it can hear, too."
"Horta!" Kirk said loudly. The creature rattled at once and then returned to silence.
"Mr. Spock, I hate to do this to you, but—it suddenly occurs to me that the Horta couldn't have destroyed that perfusion pump. It was platinum, and immune to the acid mix. It must have hidden it somewhere—and we have to get it back. You'll have to re-establish communications, no matter how painful it is."
"Certainly, Captain," Spock said promptly. "But it has no reason to give us the device—and apparently every reason to wish us off the planet."
"I'm aware of that. If we can win its confidence . . ."
Kirk took out his communicator. "Dr. McCoy. This is the Captain."
"Yes, Captain," McCoy's voice answered.
"Get your medical kit and get down here on the double. We've got a patient for you."
"Somebody injured? How?"
"I can't specify, it's beyond my competence. Just come. Twenty-third level; find us by tricorder. And hurry. Kirk out."
"I remind you, Captain," Spock said. "This is a silicon-based form of life. Dr. McCoy's medical knowledge may be totally useless."
"He's a healer. Let him heal. All right, go ahead, Mr. Spock. Try to contact it again. And try to find out why it suddenly took to murder."
The creature moved nervously as Spock approached it, but did not shy off; it merely quivered, and made its warning pebble-sound. Speck's eyes closed, and the rattling slowly died back.
Kirk's communicator beeped again. "Kirk here."
"Giotto, Captain. Are you all right?"
"Perfectly all right. Where are you?"
"We're at the end of the tunnel. Mr. Vanderberg and his men are here. They're pretty ugly. I thought I'd check with you first . . ."
"Hold them there, Commander. Under no circumstances allow them in here yet. The minute Dr. McCoy gets there, send him through."
"Aye aye, sir. Giotto out."
Spock was now deep in trance. He began to murmur.
"Pain . . . pain . . . Murder . . . the thousands . . . devils . . . Eternity ends . . . horrible . . . horrible . . . in the Chamber of the Ages . . . the Altar of Tomorrow . . . horrible . . . Murderers . . . Murderers . . ."
"Mr. Spock! The pump . . ."
"Stop them . . . kill . . . strike back . . . monsters . . ."
There was the sound of rapidly approaching footsteps and Dr. McCoy, medical bag in hand, broke through into the area. Then he stopped, obviously stunned at what he saw. Kirk silently signaled him to join them, and McCoy, giving the quiescent creature a wide berth, moved to Kirk's side. He said in a low whisper, "What in the name of . . ."
"It's wounded—badly," Kirk whispered back. "You've got to help it."
"Help—
this?"
"Take a look at it."
McCoy cautiously approached the creature, which was now as immobile as a statue; nor did Spock take any notice.
"The end of life . . . the murderers . . . killing . . . the dead children . . ."
McCoy stared at the gaping wound, and then touched it tentatively here and there. Producing his tricorder, he took a reading, at which he stared in disbelief. Then he came back to Kirk, his face indignant.
"You can't be serious. That thing is virtually made out of stone on the outside, and its guts are plastics."
"Help it. Treat it."
"I'm a doctor, not a bricklayer!"
"You're a healer," Kirk said. "That's your patient. That's an order, Doctor."
McCoy shook his head in wonder, but moved back toward the animal. Spock's eyes were still closed, his face sweating with effort. Kirk went to him.
"Spock. Tell it we're trying to help. A doctor."
"Understood. Understood. It is the end of Life. Eternity stops. Go out. Into the tunnel. To the Passage of Immortality. To the Chamber of the Ages. Cry for the children. Walk carefully in the Vault of Tomorrow. Sorrow for the murdered children. Weep for the crushed ones. Tears for the stolen ones. The thing you search for is there. Go. Go. Sadness for the end of things."
Kirk could not tell whether he was being given directions, or only eavesdropping upon a meditation. He looked hesitantly toward the tunnel entrance.
"Go!" Spock said. "Into the tunnel. There is a small passage. Quickly. Quickly. Sorrow . . . such sorrow. Sadness. Pain." There were tears running down his cheeks now. "Sorrow . . . the dead . . . the children . . ."
Kirk felt a thrill of sympathy. He did not in the least understand this litany, but no one could hear so many emotionally loaded words chanted in circumstances of such tension without reacting.
But the directions turned out to be clear enough. Within a minute he was able to return, the pump in one hand, a silicon nodule in the other.
McCoy was kneeling by the flank of the animal, and speaking into his communicator. "That's right, Lieutenant. Beam it down to me immediately. Never mind what I want it for, I just want it. Move!"
"The ages die," Spock said. "It is time to sleep. It is over. Failure. The murderers have won. Death is welcome. Let it end here, with the murdered children . . ."
"Mr. Spock!" Kirk called. "Come back! Spock!"
Spock shuddered with the effort to disengage himself. Kirk carefully put the pump on the floor of the tunnel, then waited until Spock's eyes were no longer glazed.
"I found the unit," Kirk said. "It's in good shape. I also found about a thousand of these silicon balls. They're—eggs, aren't they, Mr. Spock?"
"Yes, Captain. Eggs. And about to hatch."
"The miners must have broken into the hatchery. Their operations destroyed hundreds of them. No wonder . . ."
There was a roar of sound, and Vanderberg, Appel and what seemed to be an army of armed civilians were trying to jam themselves into the tunnel. They shouted in alarm as they saw the creature. Phasers were raised. Kirk jumped forward.
"No!" he shouted. "Don't shoot!"
"Kill it, kill it!" Appel yelled.
Kirk raised his own weapon. "The first man who shoots, dies."
"You can't mean it," Vanderberg said, pointing at the Horta with a finger quivering with hatred. "That thing has killed fifty of my men!"
"And you've killed hundreds of her children," Kirk said quietly.
"What?"
"Those 'silicon nodules' you've been collecting and destroying are eggs. Tell them, Mr. Spock."
"There have been many generations of Horta on this planet," Spock said. "Every fifty thousand years the entire race dies—all but one, like this one. But the eggs live. She protects them, cares for them, and when they hatch, she is the mother to them—thousands of them. This creature here is the mother of her race."
