"You've tried antidotes?" Agat asked, looking away from the boy's tormented face.

"All of them. Alterra, what it reminds me of is the wound you got, early in Fall, from the klois you treed. Remember that? Perhaps they make some poison from the blood or glands of klois. Perhaps these wounds will go away as that did. Yes, that's the scar—When he was a young fellow like this one," Wattock explained to Seiko and Rolery, "he went up a tree after a klois, and the scratches it gave him didn't seem much, but they puffed up and got hot and made him sick.

But in a few days it all went off again."

"This one won't get well," Rolery said very softly to Agat.

"Why do you say that?"

"I used to ...to watch the medicine-woman of my clan. I learned a little ... Those streaks, on his leg there, those are what they call death-paths."

"You know this poison, then, Rolery?"

"I don't think it's poison. Any deep wound can do it. Even a small wound that doesn't bleed, or that gets dirty. It's the evil of the weapon—"

"That is superstition," the old bonesetter said fiercely.

"We don't get the weapon-evil, Rolery," Agat told her, drawing her rather defensively away from the indignant old doctor. "We have an—"

"But the boy and Pilotson Alterra do have it! Look here —" She took him over to where one of the wounded Tevar-ans sat, a cheerful little middle-aged fellow, who willingly showed Agat the place where his left ear had been before an ax took it off. The wound was healing, but was puffed, hot, oozing ...

Unconsciously Agat put his hand up to his own throbbing, untended scalp-wound.

Wattock had followed them. Glaring at the unoffending hilf, he said, "What the local hilfs call

'weapon-evil' is, of course, bacterial infection. You studied it in school, Alterra. As human beings are not susceptible to infection by any local bacterial or viral life-forms, the only harm we can suffer is damage to vital organs, exsanguination, or chemical poisoning, for which we have antidotes—"

"But the boy is dying, Elder," said Rolery in her soft, unyielding voice. "The wound was not washed out before it was sewed together—"

The old doctor went rigid with fury. "Get back among your own kind and don't tell me how to care for humans—"

"That's enough," Agat said.

Silence.

"Rolery," Agat said, "if you can be spared here a while, I thought we might go ..." He had been about to say, "go home." "To get some dinner, maybe," he finished vaguely.

She had not eaten; he sat with her in the Assembly Room, and ate a little. Then they put on their coats to cross the unlit, wind-whistling Square to the College building, where they shared a classroom with two other couples. The dormitories in Old Hall were more comfortable, but most of the married couples of which the wife had not gone out to the Stack preferred at least this semiprivacy, when they could have it. One woman was sound asleep behind a row of desks, bundled up in her coat. Tables had been up-ended to seal the broken windows from stones and darts and wind. Agat and his wife put their coats down on the unmatted floor for bedding. Before she let him sleep, Rolery gathered clean snow from a windowsill and washed the wounds in his hand and scalp with it.

It hurt, and he protested, short-tempered with fatigue; but she said, "You are the Alterra—you don't get sick—but this will do no harm. No harm ..."

IN HIS FEVERISH sleep, in the cold darkness of the dusty room, Agat spoke aloud sometimes, and once when she was asleep he called to her from his own sleep, reaching out across the unlit abyss, calling her name from farther and farther away. His voice broke her dreaming and she woke. It was still dark.

Morning came early: light shone in around the upturned tables, white streaks across the ceiling.

The woman who had been there when they came in last night still slept on in exhaustion, but the other couple, who had slept on one of the writing-tables to avoid the drafts, roused up. Agat sat up, looked around, and said in his hoarse voice, with a stricken look, "The storm's over ..."

Sliding one of the tables aside a little they peered out and saw the world again: the trampled Square, snow-mounded barricades, great shuttered facades of the four buildings, snow-covered roofs beyond them, and a glimpse of the sea. A white and blue world, brilliantly clear, the shadows blue and every point touched by the early sunlight dazzling white.

It was very beautiful; but it was as if the walls that protected them had been torn down in the night.

Agat was thinking what she thought, for he said, "We'd better get on over to the Hall before they realize they can sit up on the rooftops and use us for target-practice." "We can use the basement tunnels to get from one building to another," one of the others said.

Agat nodded. "We will," he said. "But the barricades have got to be manned"

Rolery procrastinated till the others had gone, then managed to persuade the impatient Agat to let her look at his head-wound again. It was improved or at least no worse. His face still showed the beating he had got from her kinsmen; her own hands were bruised from handling rocks and ropes, and full of sores that the cold had made worse. She rested her battered hands on his battered head and began to laugh. "Like two old warriors," she said. "O Jakob Agat, when we go to the country under the sea, will you have your front teeth back?"

He looked up at her, not understanding, and tried to smile, but failed.

"Maybe when a f arborn dies he goes back to the stars— to the other worlds," she said, and ceased to smile.

"No," he said, getting up. "No, we stay right here. Come along, my wife."

For all the brilliant light from the sun and sky and snow, the air outside was so cold it hurt to breathe. They were hurrying across the square to the arcades of the League Hall when a noise behind them made them turn, Agat with his dartgun drawn, both ready to duck and run. A strange shrieking figure seemed to fly up over the barricade and crashed down headfirst inside it, not twenty feet from them: a Gaal, two lances bristling out between his ribs. Guards on the barricades stared and shouted, archers loaded their crossbows in haste, glancing up at a man who was yelling down at them from a shuttered window on the east side of the building above them. The dead Gaal lay face down in the bloody, trampled snow, in the blue shadow of the barricade.

One of the guards came running up to Agat, shouting "Alterra, it must be the signal for an attack—" Another man, bursting out of the door of the College, interrupted him, "No, I saw it, it was chasing him, that's why he was yelling like that—"

"Saw what? Did he attack like that all by himself?"

"He was running from it—trying to save his life! Didn't you see it, you on the barricade? No wonder he was yelling. White, runs like a man, with a neck like—God, like this, Alterra! It came around the corner after him, and then turned back."

"A snowghoul," Agat said, and turned for confirmation to Rolery. She had heard Wold's tales, and nodded. "White, and tall, and the head going from side to side ..." She imitated Wold's grisly imitation, and the man who had seen the thing from the window cried, "That's it." Agat mounted the barricade to try and get a sight of the monster. She stayed below, looking down at the dead man, who had been so terrified that he had run on his enemy's lances to escape. She had not seen a Gaal up close, for no prisoners were taken, and her work had been underground with the wounded. The body was short and thin, rubbed with grease till the skin, whiter than her own, shone like fat meat; the greased hair was interbraided with red feathers. Ill-clothed, with a felt rag for a coat, the dead man lay sprawled in his abrupt death, face buried as if still hiding from the white beast that had hunted him. The girl stood motionless near him in the bright, icy shadow of the barricade.
