Tappy and Garth began to stroll across the room. Some operators glanced up at them. Nobody made a move toward or questioned them. The two intruders were regarded as part of the crew, though some may have wondered why the woman was not in uniform. However, the crew might know only what their duties were. They might not even know why the ship was located here or what its overall mission was.
Tappy and Garth went through a door (hatchway?) into another large room. This contained several vast transparent cases, at least sixty feet high, in each of which spun an upright cylinder. Jack had no idea what their function was, but they made a loud humming noise.
The two intruders approached a door at the opposite end of the room. Two guards, bipedal cyborg Gaol, stood on each side of it. They were eight feet high, four-armed, and plated like knights. Their helmets had half-open visors concealing the face but showing large glowing eyes. Two hands on their right sides gripped the barrel of a weapon with a disk at its end.
They did not move when Garth led Tappy past them and along the wall beyond them. Then he stopped, and his wheels turned to face the wall. A huge window was set in it, and Tappy could see into the next room. Jack realized at once that it was the control center (the bridge?) of the ship. It was not all the instruments and flashing varicolored lights and crystal display blocks and the intensity of the operators that made that certain. It was the creature in the center of the room.
He— she— it, whatever it was, was sitting, if its posture could be called sitting, on a slowly rotating wide disk on top of a narrow pillar six feet high. The edge of the disk almost touched the upper end of a long narrow ramp. A four-legged being would prefer a ramp to a staircase.
"My God!" Jack said.
The thing on the disk must be the true, the basic, the real Gaol, the being in its natural form. Garth and the other Gaol he had seen were cyborgs, their naturally endowed bodies reconstructed to be Gaol-machines. Some had bodies in which part of their skin was exposed. Others were entirely armor-plated. These would be lower-class Gaol. An oppressed class with no right to object to being made half machine. Or, perhaps, they had volunteered.
In any event, weird as it was, the captain's body was what evolution had given it. It looked like a giant ratcage with a head, two arms, and four doglike legs. Its organs were suspended in a sac inside the cage. The sac filled three-fourths of the cage. Its two very long humanoid arms, anchored by a thick framework of bone on the front end of the sac, had copperish skin. The neck projecting from the sac was long and thick and molded purplish. The head was a caricature of a human being's.
Start with the bottom of the Gaol. That was a turtle's lower plate, almost six feet long. From the sides rose long curving ribs that merged with a spine arcing from the rear of the plate to its front. The blimp-shaped sac was attached to the spine with muscles Jack could clearly see through the copperish skin enclosing them. When the Gaol was momentarily before a bright light on me wall, vague shapes were silhouetted in the sac. Its organs, no doubt.
The bottom of the sac rested on a thick fleshy pad attached to the plate.
The neck extended horizontally from the front of the sac through a wide opening in the front ribs.
The head! It had almost no forehead, and the cranium had no room for even a small brain. Jack guessed that me brain was in the sac.
Brutal and fierce described the face. The jaws projected to form a mouth like a shark's. Its open mouth revealed a multitude of tiny but very sharp triangular teeth set in three rows.
It had no tongue. There were three nostrils on the end of the beastish head, two below and one above. The top one was covered by a small flap of skin that blew in and out, though not smoothly and at regular intervals. Jack could not hear it but thought that it was communicating by whistling its Morse-code-like words through that nostril.
At right angles above the jaws was a broad plane of bone in which were set two large quite human-looking eyes. These were blue. The ears resembled chrysanthemums.
What kind of a planet could have originated such a creature? It could not be an Earth-like world.
After staring through the window at the ghastly being (ghastly to Jack), Garth rolled toward the two guards. Tappy followed it until Garth whistled at her and gestured at her to wait for him. Then he lifted two extensions and shot the guards with a ray from each. The green beams cut off the heads of the guards, and these clanged on the floor and rolled a few inches. Their bodies remained upright; their arms still gripped the barrels of their weapons.
Garth opened the door to the control room, revealing to Tappy's eyes (thus Jack's) an airlock chamber. Then the Gaol entered it, and the door closed behind him.
Tappy was probably in shock because of Garth's unexpected and deadly attack. Jack did not know about that. The hatchling did not transmit emotional feelings. Not in this situation, anyway. She looked around. None of the operators in the room behind her nor in the control center had paid any attention to the killing. They may not have seen it, but the operators outside the control center must have heard the noise of the fallen heads.
"What's going on?" Jack said. He had expected any action by Tappy and Garth to be subtle and, in essence, pacifistic. But... but what? Ah! The hatchling could not enter the control room to transmit empathy to those within. The gases the Gaol breathed would kill it. If it stayed outside the room, its empathic effect would be eventually felt by the control center crew. But Garth had to take immediate action. He had decided that there was only one way to seize control of the ship. It must have been his idea since Tappy could communicate with him only through gestures. Also, he probably knew that Tappy, so full of empathy— soaked with it, in fact— would draw back from use of violence. Garth had been affected by the empathy transmitted to him, but he was still more governed by logic than feeling. A good thing, too, Jack thought.
Tappy went back to the window and looked around the side of the wall into the control room. By then, Garth had cut every Gaol operator in there and was rolling up the ramp. The captain was standing up on his four doglike legs, his arms waving, the flap over his whistling nostril going up and down. His "face" was incapable of expressing anything but ferocity, but his hands said that Garth would be sorry indeed that he had attacked the captain.
It was, of course, bravado. The captain carried no weapons.
Whatever it was saying in its whistling speech, it did not impress Garth. He wheeled onto the rotating disk, grabbed the captain's head with two suddenly extruded hands, and tore the head off from the fat neck. A dark reddish-blue blood shot out of the open neck. But Garth had rolled back out of the way of the spurt quickly enough to avoid most of it. The captain's legs gave way under him. His bottom plate struck the disk surface. The legs and arms flailed for a few seconds, then were still. The coppery skin of the sac became bluish.
Garth threw the head across the room and against a wall. With that savage gesture, he had shown that the lower-class Gaol did resent and hate their lords.
Tappy had turned away to avoid seeing more of the carnage. A moment later. Jack could see nothing through her eyes. The transmission had been cut off.
Ten minutes later, a loud clang throughout the isolation ship told Jack that Tappy and Garth were back. Airlocks opened and closed. And Tappy, sobbing, ran into his arms.
An hour later, they were eating at a small table in a corner of the main room. She had calmed down enough to have a good appetite and to be optimistic. But Jack did not entirely share her bubbling outlook, though it was difficult to resist it. He knew that the empathy that had enabled them to conquer the monitor ship was a weapon with limits. Actually, empathy alone had not done it. Violence had also been necessary. He worried that the empathy might become so strong in Tappy, himself, and Garth that they would be unable to use force against their enemy.
