In the days that followed, Aram Jerrold grew to despise the name of Santane more than he had ever despised the Tetrarchy. Deep under the turbulent sea of Atmion IV, he rested—recuperating from his ordeals and making ready for the time when the small band of peacemakers would move to forestall Santane's bid for galactic dominion.

The plan, as Kant Mikal outlined it, was simple and direct. In the colony under the sea there were forty-five men and women. These were mainly scientists and soldiers who had incurred the wrath of the Government of the Thirty Suns, though there were some, like Leader Deve Jennet of the Security Police, who carried on a double existence on Atmion IV, living both above in the Green Fortress and in the tunnels....

Of the more than three thousand Greens stationed on the prison planet, some fifty knew of the Group, and of the fifty, perhaps ten had access to the secret quarters. These Greens, at great personal risk, supplied the scientists and workers of the Group with the materials needed for their medical and physical researches.

A falsified report of Aram Jerrold's death under the disintegrators was sent to Terminus under the personal cachet of Leader Deve Jennet of the Security Police; so for the first time in many weeks Aram had a semblance of peace.

Mikal's plan was for the Group to divide into two units. One, the larger of the two, would go—at the proper time—to Kaidor V, there to establish contact with the Provincial Governor and try by any means to dissuade him from his plan to defy the Thirty Suns Government. There were several among the Group who felt that such an approach to Santane would succeed where harsher methods might well fail in the face of the Thirtieth Decant's hidden power. It was Mikal's plan to lead this delegation himself in a starship now being fitted in the central pit of the tunnel maze.

But Kant Mikal did not delude himself that Santane could be won by arguments. Another expedition to the Kaidor Sun would be dispatched at the same time. A small two-man destroyer that had been rendered—Mikal claimed—"undetectable," would leave the Atmion system with the larger vessel and land on Kaidor III, a planet uninhabited save for a few bands of degenerated experimental subjects dumped there by Santane's biological ecologists. Mikal took care to point out that Kaidor III had two large land-masses, and the landing by the two members of the Group selected for that duty would be made on the land-mass unoccupied by the unfortunate subhumans.

This expedition would remain on Kaidor III to await word from the first as to the success or failure of the Group's plan. Failing to hear from them, or hearing of failure, the small ship would proceed to Kaidor V and try to wrest the secret of the virus weapon from Santane. Plainly enough, the second expedition into the Thirtieth Decant would be a last, spasmodic attempt to save something from the ruins of galactic war. That phrase stayed with Jerrold as he listened to Kant Mikal. To save something from the ruins. That, he told himself, might well be the best the Group could accomplish with their meager resources.

During the hours that Deve was working in the Fortress, Jerrold wandered freely through the maze of underground tunnels and chambers that the Group had built. The original catacombs had been built a thousand years earlier, and the men and women of the Group had expanded and refurbished the forgotten maze to suit their purposes. Jerrold was continually amazed at what they had been able to accomplish with so little at their command and under a shroud of almost complete secrecy.

Life in the tunnels centered on the central pit—the spaceport. This, as Kant Mikal explained with considerable pride, was connected with the surface by a series of locks that emerged through the bottom of the sea in the offshore shallows down the coast from the Green Fortress. Under cover of night, a spaceship could emerge from the tunnels and lift into space without arousing the garrison of Greens who served on Atmion IV never dreaming of the quiet life beneath their feet.

Two spacecraft rested in their cradles in the pit, a medium sized merchantman, the "Star Cluster," and a Fleet scout-destroyer, "Serpent." Jerrold recognized both vessels as craft that had long ago been reported lost in space in Admiralty headquarters back on Terminus. The Serpent still carried its Fleet insigne of the Spaceship and Sun, a reminder to Aram of his former life and of the immense power of the Thirty Suns Navy. He knew only too well the position of the Group in the coming silent struggle between the galactic Tetrarchy and the rebellious Santane. They were the smallest, weakest corner in a vicious triangular madness that threatened to smash the entire civilization of the Thirty Suns.

His personal happiness at being with Deve Jennet again, and free of the haunting pain of her supposed betrayal, was mitigated by a realization of the dangers they would soon face when the Group's quixotic plan went into operation. Nor were these forebodings lessened when Kant Mikal informed him that he and Deve were the unanimous choices of the Group for the second—and secret—expedition into the Kaidor Province.

"It will be your purpose," Kant Mikal told him again, "to save something from the wreckage if all else fails...."

Aram lay comfortably under the bank of sun-lamps in the underground infirmary. The days of rest and treatment had brought him back into condition again, and he felt fit and ready for action. He had begun to chafe at the inactivity, but Kant Mikal insisted that the time to move out against Kaidor had not come, and Jerrold was forced to be content with the older man's judgment.

Deve sat with him in the infirmary, her slim body golden under the glowing lamps. Sitting near her, watching the graceful sweep of her pale hair as it brushed her shoulders, Aram was filled with a sense of well-being and contentment.

"Aram," asked Deve, "have you had time to examine the Serpent? Are you familiar with that class of ship?"

"I spent three years on Periphery Patrol with Serpent class scouts, Deve," murmured Aram sleepily. "There won't be any trouble...." He stretched himself and sat up. "But there's one thing I'd like more information on ... if I can be trusted with it."

"Aram! We trust you! You know we do ..." protested Deve.

"Kant Mikal told me the Serpent was ... undetectable. In all my years with the Fleet, I never heard of a spaceship that could not be detected."

"Avon Marsh—one of our scientists—has developed an energy shield, Aram."

"That's nothing new, Deve," said Aram. "The Fleet vessels have had them for years. They use them against attack by ray weapons of all kinds."

"But this reaches into the highest frequencies," Deve explained. "It shunts all radiation around the ship. Of course, it can't be used during second order flight above light speed, but it wouldn't be of any value then, anyway."

"You mean it shunts all radiation around the ship? All? Even light?" demanded Jerrold with sudden interest.

"Yes. At close observational ranges it results in a slight distortion—like a very clear lens, but—"

"Then the ship is ... invisible?" Aram asked incredulously.

Deve Jennet smiled. "Yes, among other things. And it prevents a radio echo being sent back to a detector, too."

Aram sank back thoughtfully. An invisible ship! His spaceman's mind toyed with the thought. It was like something from a naval officer's dream fantasies. A battleship so equipped could very nearly rule the plenum...! But Deve's next words cut that dream short.

"The field is so limited, though," she said, "that only a two-man scout can be equipped with it. And since the shield works two ways, the occupants of the ship are blind. Nothing outside the ship itself can be seen."

Jerrold was about to reply when Kant Mikal burst into the room. His grey hair was matted with blood, and his face was pale and drawn with pain and anxiety.

"I should have listened to you, Jerrold," he breathed heavily. "We should have moved out long ago!"

"Kant! You're hurt," cried Deve.

Mikal gestured impatiently. "It's nothing! We have to get out immediately! Get ready...!"

Jerrold and Deve were on their feet, reaching for their cloaks.

"What's happened?" asked Aram.

"The Greens have found the tunnel entrance. I think they must have caught one of our topside people with a mental probe, I don't know for sure. But there's fighting in the tube-shafts now. We have to get to the ships!"

Aram cursed. "Are there any weapons nearby?"

The grey haired officer shook his head. "None. Only the medical instruments here."

Aram ransacked the wall cabinets and produced a single small scalpel. "This will have to do," he muttered.

"If we can reach the pit," said Kant Mikal, "the steelite doors may give us enough time to get clear. They're disintegrator-resistant."

"Let's go," said Aram tensely. "Ready?"

Deve and Mikal nodded and followed him as he opened the door to the corridor and stepped out. The tunnel was deserted, but there were muffled sounds of fighting coming through the ventilators. Aram sprinted toward the pit, his bare feet soundless on the stone floor. Deve and Mikal ran silently beside him.

As they came to a turn in the tube, a single Green seemed to appear out of nowhere. Aram had a fleeting glimpse of a pistol being raised and he felt the hot, searing touch of a graze as he launched himself bodily at the man.

There was a crashing roar as the tetrol shell exploded harmlessly against the stone wall of the tunnel, sending echoes reverberating down the long passageway. Aram caught the Green in the pit of the stomach with the full force of his charge. The man doubled up painfully, dropping his weapon to the floor. Aram rolled to his feet, catlike. The Green roared with rage and lunged at him. Aram stepped under the attack and brought his two clenched fists down on the back of the man's neck. The Green staggered and spun about, catching Aram in a vise-like embrace. The policeman was huge, and as his arms closed about Aram's lighter frame, Aram could feel his ribs being crushed. His hand closed on the scalpel he had thrust into the waistband of his shorts. He raised it high and drove it hard into the man's broad back. The Green stiffened. With an incredulous expression, he released Aram and toppled to the stone floor.

Aram leaned against the wall of the tunnel, panting, sickened. His hands were red with blood. From somewhere down the tunnel came the sound of booted feet clattering on the stones. Suddenly another Green rounded the turn, an energy rifle in his hands. Aram straightened for the expected attack, but the Green stopped abruptly, his head vanishing into a red smear as another crashing roar echoed down the corridor. As he sank to the floor, Aram turned to see Kant Mikal lowering the first Green's still smoking pistol.

"Let's keep going," Mikal muttered breathlessly.

Stopping only to pick up the fallen Green's rifle, Aram, Kant Mikal and Deve ran on toward the pit.

"Will the others try to make the spaceport?" gasped Jerrold as they ran.

"There's nowhere else to go," returned Mikal simply.

The Greens had not completely occupied the tunnels, for they met no more opposition. The sounds of fighting had stopped, though, as they burst into the large chamber that housed the spacecraft, and Aram realized that the Greens were gathering their forces for an attempt to prevent the Group's escape in the vessels. Aram looked about him with a sick heart. Of the original forty-five that had been in the tunnels before the attack, only ten besides himself and Deve had reached the pit. The others, they told him, had been killed or captured by the Greens, and one of them must have been forced to tell of the spaceships and the plan of escape through the locks.

The steelite doors of the pit were closed, and the remnants of the Group straggled aboard the Star Cluster. Kant Mikal took immediate command of the ship and made ready for the perilous passage through the locks to the sea above. He laid a hand on Aram's shoulder and spoke with feeling. "This isn't the way I planned it, Jerrold, but we must do the best we can. Good luck!"

Aram helped rig the Star Cluster for flight and then stepped down onto the floor of the pit. He realized only too well, as he stood with Deve alone on the floor of the vast chamber, that they would have to wait until the heavy Star Cluster had cleared the locks before they could blast free of the cavern in the Serpent.

He helped Deve through the valve of the small scout ship and hoisted himself up, crouching in the open lock with the dead Green's energy rifle, ready to pick off the first Green to come through the door. The Greens had brought their disintegrators into play, and within minutes the door would reach its limit of endurance. The steelite panels already glowed red....

The Star Cluster lifted from its cradle with a hissing roar that set the smaller Serpent to trembling. The first lock opened above it and it was gone into the black maw of the vertical shaft, its tail-flare vanishing in the stygian darkness. The lock did not close, and Aram Jerrold breathed a silent message of thanks to Kant Mikal who had left it open to ease the Serpent's escape.

"How long will it take them to clear the remaining locks?" Jerrold asked Deve anxiously.

Deve divined his thoughts, and shook her head. "More time than it will take the Greens to cut through that door!"

Aram was struck with an idea. "The shield, Deve! The energy shield!"

For a moment hope lighted her face, but it quickly faded. "There is a time-lag when the shield is deactivated, Aram," she said. "If we use it now, we won't be able to operate the locks in time. They are radio-controlled from inside the ship and the shield stops all radiation ... both ways!"

"Then we'll ram the locks!"

"Will the ship stand it?"

"I don't know, Deve, but it's our only chance. If we can confuse them just long enough to get under way, we may make it. Show me how the shield is energized."

Deve shrugged and sat down before the control panel. Her fingers flashed lightly over the banks of switches. A low whining of generators started deep in the vitals of the small starship. Aram, watching the process, glanced through the ports at the melting steelite door of the cavern, and he was amazed to see the scene fade before his eyes into a murky grayness.

"They can't see us now," Deve Jennet said with a slow smile, "and we can't see them."

"Let's go," breathed Aram.
