said impatiently, "How can you know they're coming?"
Stark shivered, a shallow rippling of the flesh that had nothing to do with cold, and every muscle of his body came alive. Phobos plunged downward. The moonlight dimmed and changed, and the plain was very empty, very still.
"They will wait for darkness. They will have an hour or so, between moonset and dawn."
Thanis muttered, "Dreams! Besides, I'm cold." She hesitated, and then crept in under Balin's cloak. Stark had gone away from her. She watched him sulkily where he leaned upon the stone. He might have been part of it, as dark and unstirring.
Deimos sank low toward the west.
Stark turned his head, drawn inevitably to look toward the cliffs above Kushat, soaring upward to blot out half the sky. Here, close under them, they seemed to tower outward in a curving mass, like the last wave of eternity rolling down, crested white with the ash of shattered worlds.
I have stood beneath those cliffs before. I have felt them leaning down to crush me, and I have been afraid.
He was still afraid. The mind that had poured its memories into that crystal lens had been dead a million years, but neither time nor death had dulled the terror that beset Ban Cruach in his journey through that nightmare pass.
He looked into the black and narrow mouth of the Gates of Death, cleaving the scarp like a wound, and the primitive ape-thing within him cringed and moaned, oppressed with a sudden sense of fate.
He had come painfully across half a world, to crouch before the Gates of Death. Some evil magic had let him see forbidden things, had linked his mind in an unholy bond with the long-dead mind of one who had been half a god. These evil miracles had not been for nothing. He would not be allowed to go unscathed.
He drew himself up sharply then, and swore. He had left N'Chaka behind, a naked boy running in a place of rocks and sun on Mercury. He had become Eric John Stark, a man, and civilized. He thrust the senseless premonition from him, and turned his back upon the mountains.
Deimos touched the horizon. A last gleam of reddish light tinged the snow, and then was gone.
Thanis, who was half asleep, said with sudden irritation, "I do not believe in your barbarians. I'm going home." She thrust Balin aside and went away, down the steps.
The plain was now in utter darkness, under the faint, far Northern stars.
Stark settled himself against the parapet. There was a sort of timeless patience about him. Balin envied it. He would have liked to go with Thanis. He was cold and doubtful, but he stayed.
Time passed, endless minutes of it, lengthening into what seemed hours.
Stark said, "Can you hear them?"
"No."
"They come." His hearing, far keener than Balin's, picked up the little sounds, the vast inchoate rustling of an army on the move in stealth and darkness. Light-armed men, hunters, used to stalking wild beasts in the show. They could move softly, very softly.
"I hear nothing," Balin said, and again they waited.
The westering stars moved toward the horizon, and at length in the east a dim pallor crept across the sky.
The plain was still shrouded in night, but now Stark could make out the high towers of the King City of Kushat, ghostly and indistinct—the ancient, proud high towers of the rulers and their nobles, set above the crowded Quarters of merchants and artisans and thieves. He wondered who would be king in Kushat by the time this unrisen sun had set.
"You were wrong," said Balin, peering. "There is nothing on the plain."
Stark said, "Wait."

Swiftly now, in the thin air of Mars, the dawn came with a rush and a leap, flooding the world with harsh light. It flashed in cruel brilliance from sword-blades, from spearheads, from helmets and burnished mail, from the war-harness of beasts, glistened on bare russet heads and coats of leather, set the banners of the clans to burning, crimson and gold and green, bright against the snow.
There was no sound, not a whisper, in all the land.
Somewhere a hunting horn sent forth one deep cry to split the morning. Then burst out the wild skirling of the mountain pipes and the broken thunder of drums, and a wordless scream of exultation that rang back from the Wall of Kushat like the very voice of battle. The men of Mekh began to move.
Raggedly, slowly at first, then more swiftly as the press of warriors broke and flowed, the barbarians swept toward the city as water sweeps over a broken dam.
Knots and clumps of men, tall men running like deer, leaping, shouting, swinging their great brands. Riders, spurring their mounts until they fled belly down. Spears, axes, sword-blades tossing, a sea of men and beasts, rushing, trampling, shaking the ground with the thunder of their going.
And ahead of them all came a solitary figure in black mail, riding a raking beast trapped all in black, and bearing a sable axe.
Kushat came to life. There was a swarming and a yelling in the streets, and soldiers began to pour up onto the Wall. A thin company, Stark thought, and shook his head. Mobs of citizens choked the alleys, and every rooftop was full. A troop of nobles went by, brave in their bright mail, to take up their post in the square by the great gate.
Balin said nothing, and Stark did not disturb his thoughts. From the look of him, they were dark indeed.
Soldiers came and ordered them off the Wall. They went back to their own roof, where they were joined by Thanis. She was in a high state of excitement, but unafraid.
"Let them attack!" she said. "Let them break their spears against the Wall. They will crawl away again."
Stark began to grow restless. Up in their high emplacements, the big ballistas creaked and thrummed. The muted song of the bows became a wailing hum. Men fell, and were kicked off the ledges by their fellows. The blood-howl of the clans rang unceasing on the frosty air, and Stark heard the rap of scaling ladders against stone.
Thanis said abruptly, "What is that—that sound like thunder?"
"Rams," he answered. "They are battering the gate."
She listened, and Stark saw in her face the beginning of fear.
It was a long fight. Stark watched it hungrily from the roof all that morning. The soldiers of Kushat did bravely and well, but they were as folded sheep against the tall killers of the mountains. By noon the officers were beating the Quarters for men to replace the slain.
Stark and Balin went up again, onto the Wall.
The clans had suffered. Their dead lay in windrows under the Wall, amid the broken ladders. But Stark knew his barbarians. They had sat restless and chafing in the valley for many days, and now the battle-madness was on them and they were not going to be stopped.
Wave after wave of them rolled up, and was cast back, and came on again relentlessly. The intermittent thunder boomed still from the gates, where sweating giants swung the rams under cover of their own bowmen. And everywhere, up and down through the forefront of the fighting, rode the man in black armor,
