couldn't drag his immense weight into the shade.
Brion lay on his back in the sun, sweating. Lea saw this and knew that he was still alive. Yet what was happening? She groped for memory in the red haze of her mind, but could remember nothing from her medical studies that would explain this. On every square inch of his body the sweat glands seethed with sudden activity. From every pore oozed great globules of oily liquid, far thicker than normal perspiration. Brion's arms rippled with motion and Lea stared, horrified as the hairs there writhed and stirred as though endowed with separate life. His chest rose and fell rapidly, deep, gasping breaths wracking his body. Lea could only stare through the dim redness of unreality and wonder if she was going mad before she died.
A coughing fit broke the rhythm of his rasping breath, and when it was over his breathing was easier. The perspiration still covered his body, the individual beads touching and forming tiny streams that seeped down his body and vanished in the sand. He stirred and rolled onto his side, facing her. His eyes open and normal now as he smiled.
'Didn't mean to frighten you. It caught me suddenly, coming at the wrong season and everything. It was a bit of a jar to my system. I'll get you some water now, there's still a bit left.'
'What happened? When you looked like that, when you fell—'
'Take two swallows, no more,' he said, holding the canteen to her mouth. 'Just summer change, that's all. Happens to us every year on Anvhar—only not that violently, of course. In the winter our bodies store a layer of fat under the skin for insulation and sweating almost ceases completely. Lot of internal changes, too. When the weather warms up the process is reversed. The fat is metabolized and the sweat glands enlarge and begin working overtime as the body prepares for two months of hard work, heat and little sleep. I guess the heat here triggered off the summer change early.'
'You mean—you've adapted to this terrible planet?'
'Just about. Though it does feel a little warm. I'll need a lot more water soon, so we can't remain here. Do you think you can stand the sun if I carry you?'
'No, but I won't feel any better staying here.' She was light-headed, scarcely aware of what she said. 'Keep going, I guess. Keep going.'
As soon as she was out of the shadow of the rock the sunlight burst over her again in a wave of hot pain. She was unconscious at once. Her slight weight was no burden to Brion and he made his best speed, heading toward the spot on the horizon where the sun would set. Without water he knew he could not last more than a day or two at best.
When sunset came he was still walking steadily. Only when the air chilled did he stop to dress them both in the warm clothes and push on. Lea regained consciousness in the cool night air and finished the last mouthfuls of water. She wanted to walk, but could only moan with pain when her burned feet touched the ground. He put ointment on them and wrapped them in cloth. They were too swollen to go back into the ragged shoes. Lifting his burden he walked on into the night, following the guiding stars.
Except for the nagging thirst, it was an easy night. He wouldn't need sleep for two or three days more, so that didn't bother him. His muscles had a plentiful supply of fuel at hand in the no longer wanted subcutaneous fatty layer. Metabolizing it kept him warm. By running at a ground-eating pace whenever the footing was smooth he made good time. By dawn he was feeling a little tired and was at least ten kilos lighter due to the loss of the burned up fat.
There was no sight of the city yet. This was the last day. Massive as the adaptation of his body was to the climate, it still needed water to function. As his pores opened in the heat he knew the end was very close. Weaving, stumbling, trying not to fall with the unconscious girl, he climbed dune after unending dune. Before his tortured eyes the sun expanded and throbbed like a gigantic beating heart. He struggled to the top of the mountain of sand and looked at the Disan standing a few feet away.
They were both too surprised by the sudden encounter to react at once. For a breath of time they stared at each other, unmoving. When they reacted it was with the same defense of fear. Brion dropped the girl, bringing the gun up from the holster in the return of the same motion. The Disan jerked a belled tube from his waistband and raised it to his mouth.
Brion didn't fire. A dead man had taught him how to train his empathetic sense, and to trust it. In spite of the fear that wanted him to jerk the trigger, a different sense read the unvoiced emotions of the native Disan. There was fear there, and hatred. Welling up around these was a strong desire not to commit violence this time, to communicate instead. Brion felt and recognized all this in a small part of a second. He had to act instantly to avoid a tragic accident. A jerk of his wrist threw the gun to one side.
As soon as it was gone, he regretted his loss. He was gambling their lives on an ability he still was not sure of. The Disan had the tube to his mouth when the gun hit the ground. He held the pose, unmoving, thinking. Then he accepted Brion's action and thrust the tube back into his waistband.
'Do you have any water?' Brion asked, the guttural Disan words hurting his throat.
'I have water,' the man said. He still didn't move. 'Who are you?'
'We're from offplanet. We had ... an accident. We want to go to the city. The water.'
The Disan looked at the unconscious girl and made his decision. Over one shoulder he wore one of the green objects that Brion remembered from the solido. He pulled it off and the thing writhed slowly in his hands. It was alive. A green length a meter long, like a noduled section of a thick vine. One end flared out into a petallike formation. The Disan took a hook-shaped object from his waist and thrust it into the petaled orifice. When he turned the hook in a quick motion the length of green writhed and curled around his arm. He pulled something small and dark out and threw it to the ground, extending the twisting green shape towards Brion. 'Put your mouth to the end and drink,' he said.
Lea needed the water more, but he drank first, suspicious of the living water source. A hollow below the writhing petals was filling with straw-colored water from the fibrous, reedy interior. He raised it to his mouth and drank. The water was hot and tasted swampy. Sudden sharp pains around his mouth made him jerk the thing away. Tiny glistening white barbs projected from the petals, pink tipped now with his blood. Brion swung towards the Disan angrily—and stopped when he looked at the other man's face. His mouth was surrounded by many small scars.
'The vaede does not like to give up its water, but it always does,' the man said.
Brion drank again then put the vaede to Lea's mouth. She moaned without regaining consciousness, her lips seeking reflexively for the life-saving liquid. When she was satisfied Brion gently drew the barbs from her flesh and drank again. The Disan hunkered down on his heels and watched them expressionlessly. Brion handed back the vaede, then held some of the clothes so Lea was in their shade. He settled into the same position as the native and looked closely at him.
Squatting immobile on his heels, the Disan appeared perfectly comfortable under the flaming sun. There was no trace of perspiration on his naked, browned skin. Long hair fell to his shoulders and startlingly blue eyes stared back at Brion from deep-set sockets. The heavy kilt around his loins was the only garment he wore. Once more the vaede rested over his shoulder, still stirring unhappily. Around his waist was the same collection of leather, stone and brass objects that had been in the solido. Two of them now had meaning to Brion. The tube-and-mouthpiece; a blowgun of some kind. And the specially shaped hook for opening the vaede. He wondered if the other strangely formed things had equally realistic functions. If you accepted them as artifacts with a purpose—not barbaric decorations—you had to accept their owner as something more than the crude savage he resembled.
'My name is Brion. And you—'
'You may not have my name. Why are you here? To kill my people?'
Brion forced the memory of the last night away. Killing was just what he had done. Some expectancy in the man's manner, some sensed feeling of hope prompted Brion to speak the truth.
'I'm here to stop your people from being killed. I believe in the end of the war.'
'Prove it.'
'Take me to the Cultural Relationships Foundation in the city and I'll prove it. I can do nothing here in the desert. Except die.'
For the first time there was emotion on the Disan's face. He frowned and muttered something to himself.
