Sense of Obligation

against life. And saved his enemies because they were medvirk.

With this realization came the painful knowledge that the planet and the people that had produced this understanding were dead.

In the cavern the magter saw the destruction of their plans, and the cave mouth from which the bullets had come. Silently they rushed to kill their enemy. A concerted wave of emotionless fury.

Brion and Ulv fought back. Even the knowledge that he was doomed no matter what happened could not resign Brion to death at the hands of the magter. To Ulv, the decision was much easier. He was simply killing umedvirk. A believer in life, he destroyed the anti-life.

They retreated into the darkness, still firing. The magter had lights and ion-rifles, and were right behind them. Knowing the caverns better than the men they chased, pursuers circled. Brion saw lights ahead and dragged Ulv to a stop.

'They know their way through these caves, and we don't,' he said. 'If we try to run, they'll just shoot us down. Let's find a spot we can defend and settle into it.'

'Back here,' Ulv gave a tug in the right direction, 'there is a cave with only one very narrow entrance.'

'Let's go!'

Running as silently as they could in the darkness, they reached the deadend cavern without being seen. What noise they made was lost in other footsteps that echoed and sounded through the connecting caves. Once inside they found cover behind a ridge and waited. The end was certain.

The magter ran swiftly into their cave, flashing his light into all the places of concealment. The beam passed over the two hidden men and at the same instant Brion fired. The shot boomed loudly as the magter fell. Even if his loss was not known, the shot would surely have been heard.

Before anyone else came into the cave, Brion ran over and grabbed the still functioning light. Propping it on the rocks so it shone on the entrance, he hurried back to shelter beside Ulv. They waited for the attack.

It was not long in coming. Two magter rushed in and died. There were more outside, and Brion wondered how long it would be before they remembered the grenades and rolled one into their shelter.

An indistinct murmur sounded outside and some sharp explosions. In their shelter, Brion and Ulv crouched low and wondered why the attack didn't come. Then one of the magter came in and Brion hesitated before shooting.

The man had backed in, firing behind him as he came.

Ulv had no compunctions about killing, only his darts couldn't penetrate the magter's thick clothing. As the magter turned Ulv's breath pulsed once and death stung the back of the other man's hand. He collapsed into a crumpled heap.

'Don't shoot,' a voice said from outside the cave, and a man stepped through the swirling dust and smoke to stand in the beam from the light.

Brion clutched wildly at Ulv's arm, dragging the blowgun from the Disan's mouth.

The man in the light wore a protective helmet, thick boots and a pouch-hung uniform.

He was a Nyjorder.

This shock of reality was almost impossible to accept. Brion had heard the bombs fall. Yet the Nyjord soldier was here. The two facts couldn't be accepted together.

'Would you keep a hold on his arm, sir, just in case,' the soldier said, glancing warily at Ulv's blowpipe. 'I know what those darts can do.' He pulled a microphone from one of his pockets and spoke into it.

More soldiers crowded into the cave and Professor-Commander Krafft came in behind them. He looked strangely out of place in the dusty combat uniform. The gun was even more grotesque in his blue-veined hand. After relievedly giving the pistol to the nearest soldier, he stumbled quickly over to Brion and took his hand.

'It is a profound and sincere pleasure to meet you in person,' he said. 'And your friend Ulv as well.'

'Would you kindly explain what is going on,' Brion said thickly. He was obsessed by the strange feeling that none of this could possibly be happening.

'We will always remember you as the man who saved us from ourselves,' Krafft said, once again the professor instead of the commander.

'What he wants are facts, Grandpa, not speeches,' Hys said. The bent form of the leader of the rebel Nyjord army pushed through the crowd of taller men until he stood next to Krafft. 'Simply stated, Brion, your plan succeeded. Krafft relayed your message to me—and as soon as I heard it I turned back and met him on his ship. I'm sorry that Telt's dead—but he found what we were looking for. I couldn't ignore his report of radioactive traces. Your girl friend arrived with the hacked up corpse at the same time I did, and we all took a long look at the green leech in its skull. Her explanation of what it is made significant sense. We were already carrying out landings when we had your call about something having been stored in the magter tower. After that it was just a matter of following tracks—and the transmitter you planted.'

'But the explosions at midnight,' Brion broke in, 'I heard them!'

'You were supposed to,' Hys laughed. 'Not only you, but the magter in this cave. We figured they would be armed and the cave strongly defended. So at midnight we dropped a few large chemical explosive bombs at the entrance. Enough to kill the guards without bringing the roof down. We also hoped that the magter deeper in would leave their posts or retreat from the imagined radiation. They did. Worked like a charm. We came in quietly and took them by surprise. Made a clean sweep. Killed the ones we couldn't capture.'

'One of the renegade jump-space technicians was still alive,' Krafft said. 'He told us about your stopping the bombs aimed at Nyjord, the two of you.'

None of the Nyjorders there could add anything to his words, not even the cynical Hys. Yet Brion could empathize their feelings, the warmth of their intense relief and happiness. It was a sensation he would never forget.

'There is no more war,' Brion translated for Ulv, realizing that the Disan had understood nothing of the explanation. As he said it, he realized that there was one glaring error in the story.

'You couldn't have done it,' Brion said, astonished. 'You landed on this planet before you had my message about the tower. That means you still expected the magter to be sending their bombs to Nyjord—and you made the landings in spite of this knowledge.'

'Of course,' Professor Krafft said, astonished at Brion's lack of understanding. 'What else could we do? The magter are sick!'

Hys laughed aloud at Brion's baffled expression. 'You have to understand Nyjord psychology,' he said. 'When it was a matter of war and killing my planet could never agree on an intelligent course. War is so alien to our philosophy that it couldn't even be considered correctly. That's the trouble with being a vegetable eater in a galaxy of carnivores. You're easy prey for the first one that lands on your back. Any other planet would have jumped on the magter with both feet and shaken the bombs out of them. We fumbled it so long it almost got both worlds killed. Your mind-parasite drew us back from the brink.'

'I still don't understand,' Brion said. 'Why—'

'Simple matter of definition. Before you came we had no way to deal with the magter here on Dis. They really were alien to us. Nothing they did made sense—and nothing we did seemed to have the slightest effect on them. But you discovered that they were sick, and that's something we know how to handle. We're united again, my rebel army was instantly absorbed into the rest of the Nyjord forces by mutual agreement. Doctors and nurses are on the way here now. Plans were put under way to evacuate what part of the population we could until the bombs were found. The planet is united again and working hard.'

'Because the magter are sick, infected by a destructive life form?' Brion asked.

'Exactly so,' Professor Krafft said. 'We are civilized, after all. You can't expect us to fight a war—and you surely can't expect us to ignore the plight of sick neighbors?'

'No ... you surely can't,' Brion said, sitting down heavily. He looked at Ulv, who knew nothing of the incomprehensible speech. Beyond him Hys wore his most cynical expression as he considered the frailties of his people.

'Hys,' Brion called out. 'You translate all that into Disan and explain to Ulv. I wouldn't dare.'
