“How much more?” a woman demanded, her voice too sharp, addressing herself to the sinister passages. Aton agreed: what other pressures would be brought to bear before Chthon let them go?
A shout. It was the voice of one of the women on scout duty. Teams always went out on prowl, now, while the main group rested. The chimera never attacked an alert formation.
The others gathered around. It was one of Bedside’s cairns, with a message scratched on the floor. The rock was soft, here, and could be decorated readily.
“What does it mean?”
It was the typical skull illustration of danger, but without the crossbones. A single word was underneath.
Aton spelled out the crude letters: MYXO. “Must be a medical term,” he said.
“Myxo,” Bossman muttered. “Don’t mean anything to me. Ain’t like him to leave his picture unfinished.”
“Either something drove him off—” a woman suggested.
“Or there’s a Myxo ’round here that don’t quite kill,” another finished.
They stood in a circle, looking at each other. No one knew. But one thing experience had made plain: Doc Bedside’s humor was scant, and his warnings were not to be ignored.
“We better move on fast,” Bossman decided. They were tired, but there was no dissent. There was danger here.
Fifteen minutes later a woman fell, clutching at her throat and head. No animal had attacked her, and nothing was wrong—visibly.
They halted for a brief consultation. Life was more precious at this juncture. If many more were lost, the party would be too small to win through the remaining challenges. There had to be scouting parties, guards, and reliefs for these, as well as individuals for special assignments for unpleasant work. Once the disciplined system broke down, the demise of the remainder would accelerate. Concern for the laggards was something new—but necessary.
They camped and made the woman comfortable. She was examined closely. What was the matter with her?
Her breathing was labored, rasping. Gradually her skin whitened. A slimy mucus was exuded all along her body, and a stomach-twisting odor arose from it. She had fallen prey to a disease—the first disease known in Chthon.
“We better kill her now,” a woman urged, “before it spreads.”
Bossman considered the matter.
“Why bother?” Aton said. “We’ve all been exposed by this time.”
“How did she catch it?”
“I ain’t seen nothing like this before.”
“Leave her here and get out,” a man cried, the contagious tinge of panic coming out.
A second woman fell. “Too late,” Bossman said. It was always too late by the time they understood the manner of the next danger. “Better stick together and fight.”
“Fight what?” the man wanted to know. But the question was academic: a third woman was toppling.
In quick succession the women fell, to lie with skins smeared white. They did not appear to be in pain, after the initial spasm; but the acrid exudation grew steadily worse. It re-formed the moment the skin was wiped clean, and it was everywhere.
Aton, Bossman, and the other four men stood by helplessly. During the trek the men had taken more risks and died more readily, and the chimera seemed to prefer them. Now the tally was being reversed, as the mysterious malady mummified the females. Bossman did what he could. Taking a woman by the foot, he dragged her to the nearest pool and tried to wash the slime away. This seemed to help; she sat up and began to splash herself, slowly, but with some effectiveness.
They did the same for the others, dumping them into the water and holding up their heads by the hair until they revived. The crisis seemed to be over.
Then it started on the men.
The masculine attacks, as though to make up for lost time, were far more violent. Almost as one, the men went into convulsions. Their skin reacted, sending out the calcifying sweat. It was the women’s turn to play nurse. Soon everyone was in the pool, and the water took on a milky hue. If this were to be a fatal disease, all would die.
But Bedside had omitted the bones.
Aton was the first of the men to recover. He had experienced no pain, aside from the extreme tightness of throat that had restricted breathing. Instead there had been a lassitude, a desire to let go, to drift—a desire shocked away by the cold water. Now, in reaction, he was disgusted. Not at the ludicrous communal bath, but at his failure to resist the disease.
“The Myxo!” he exclaimed. “This must be what Bedside was warning us about. Some kind of virus.”
The nearest woman looked at him. The black-haired one, no longer as pretty as she had been before the trek, but still interesting. She had always steered clear when Garnet was about; but Garnet had fed the creature with the white wake while the others were swimming safely across the river, and now the field was clear.
If things ever eased up enough to permit a relaxed disbursement… “Must be in the air,” she said. “We better get out.” And he had never learned her name.
Bossman revived. “Yeah,” he agreed.
They moved on, trying to escape the malady they knew they carried with them. They did not get far.
The women were first, again. This time it was fever, rising unbelievably. There were no gauges, no thermometers here, but the simple touch of the skin served notice that there were several degrees between the sick and the well. The fever rose to the limit of human endurance. Then it increased.
They no longer tried to march. It was obvious that they could not outrun it, or hide from it. The passage ahead expanded into a bubble-dome, another relic of Chthon’s formation, out of place in this section of the caverns, but welcome. The base was filled with clear, shallow water. This was convenient and relatively safe. They settled down, in and beside the pool, waiting for what might come.
At what point, Aton wondered, did brain damage occur? Surely this fever was already cooking the neural tissues of the present victims. There was no specific limit to the temperature a living body could endure, despite the attitude of the medics—but such fever was dangerous. Was this the actual course of the Bedside madness? If so, was it possible to circumvent it?
Was there some way to hold the fever down until the illness ran its course?
He gazed into the water. It was cold; they were far below the fire cycle. Fully immersed—
The fever came. Aton slipped into the pool and lay down, propping himself in such a way that his face alone was exposed to the air. The relief was a blessed thing. But the juices in him were boiling, the tissues curling. The inferno of the blue garnet itself had hardly been as hot as this.
Vaguely he heard scuffling and splashing around him. Something was going on, but he was afraid to sit up and look, afraid to leave the water because of an irrational fear that he would burst into flame the moment he did so.
But he had to. He was finding it difficult to breathe for some reason. There was an obstruction.
Aton sat up and put his hand to his mouth to find it slimed with a thick layer of putrid paste. Inside, this time, obscuring nasal and glottal passages, instead of external skin. His nose was already entirely blocked. He hooked one finger into his mouth and scraped out a wad of yellow mucus, rank and rotten, which hardened immediately upon exposure to the air. No wonder his breathing was difficult. The stuff clogged the breathing passages by solidifying around them.
He looked around, or tried to, and discovered that a similar pus rimmed his eyes, almost closing them. It was the same for the others, male and female alike; the illness no longer seemed to distinguish between the sexes. Some were already retching, nauseated by the deposits. One man yanked out a huge solid chunk, and there was blood on it from the adhering membrane. No one dared to let it collect, or the choice would be between mutilation and suffocation. And still the fever raged.
