made his very body change, draw in upon itself and flatten forward, so that when at last he went on again he was more like a four-footed thing than a man walking upright.
Infinitely wary, silent, moving surely over the ice and the tumbled rock, he followed Balin. He had ceased to think. He was going now on sheer instinct.
The pass led on and on. It grew darker, and in the dim uncanny twilight there were looming shapes that menaced him, and ghostly wings that brushed him, and a terrible stillness that was not broken by the eerie voices of the wind.
Rock and mist and ice. Nothing that moved or lived. And yet the sense of danger deepened, and when he paused the beating of his heart was like thunder in his ears.
Once, far away, he thought he heard the echoes of a man's voice crying, but he had no sight of Balin.
The pass began to drop, and the twilight deepened into a kind of sickly night.
On and down, more slowly now, crouching, slinking, heavily oppressed, tempted to snarl at boulders and tear at wraiths of fog. He had no idea of the miles he had travelled. But the ice was thicker now, the cold intense.
The rock walls broke off sharply. The mist thinned. The pallid darkness lifted to a clear twilight. He came to the end of the Gates of Death.
Stark stopped. Ahead of him, almost blocking the end of the pass, something dark and high and massive loomed in the thinning mists.
It was a great cairn, and upon it sat a figure, facing outward from the Gates of Death as though it kept watch over whatever country lay beyond.
The figure of a man in antique Martian armor.
After a moment, Stark crept toward the cairn. He was still almost all savage, torn between fear and fascination.
He was forced to scramble over the lower rocks of the cairn itself. Quite suddenly he felt a hard shock, and a flashing sensation of warmth that was somehow inside his own flesh, and not in any tempering of the frozen air. He gave a startled leap forward, and whirled, looking up into the face of the mailed figure with the confused idea that it had reached down and struck him.
It had not moved, of course. And Stark knew, with no need of anyone to tell him, that he looked into the face of Ban Cruach.
* * * * *
It was a face made for battles and for ruling, the bony ridges harsh and strong, the hollows under them worn deep with years. Those eyes, dark shadows under the rusty helm, had dreamed high dreams, and neither age nor death had conquered them.
And even in death, Ban Cruach was not unarmed.
Clad as for battle in his ancient mail, he held upright between his hands a mighty sword. The pommel was a ball of crystal large as a man's fist, that held within it a spark of intense brilliance. The little, blinding flame throbbed with its own force, and the sword-blade blazed with a white, cruel radiance.
Ban Cruach, dead but frozen to eternal changelessness by the bitter cold, sitting here upon his cairn for a million years and warding forever the inner end of the Gates of Death, as his ancient city of Kushat warded the outer.
Stark took two cautious steps closer to Ban Cruach, and felt again the shock and the flaring heat in his blood. He recoiled, satisfied.
The strange force in the blazing sword made an invisible barrier across the mouth of the pass, protected Ban Cruach himself. A barrier of short waves, he thought, of the type used in deep therapy, having no heat in themselves but increasing the heat in body cells by increasing their vibration. But these waves were stronger than any he had known before.
A barrier, a wall of force, closing the inner end of the Gates of Death. A barrier that was not designed against man.
Stark shivered. He turned from the sombre, brooding form of Ban Cruach and his eyes followed the gaze of the dead king, out beyond the cairn.
He looked across this forbidden land within the Gates of Death.
At his back was the mountain barrier. Before him, a handful of miles to the north, the terminus of the polar cap rose like a cliff of bluish crystal soaring up to touch the early stars. Locked in between those two titanic walls was a great valley of ice.
White and glimmering that valley was, and very still, and very beautiful, the ice shaped gracefully into curving domes and hollows. And in the center of it stood a dark tower of stone, a cyclopean bulk that Stark knew must go down an unguessable distance to its base on the bedrock. It was like the tower in which Camar had died. But this one was not a broken ruin. It loomed with alien arrogance, and within its bulk pallid lights flickered eerily, and it was crowned by a cloud of shimmering darkness.
It was like the tower of his dread vision, the tower that he had seen, not as Eric John Stark, but as Ban Cruach!
Stark's gaze dropped slowly from the evil tower to the curving ice of the valley. And the fear within him grew beyond all bounds.
He had seen that, too, in his vision. The glimmering ice, the domes and hollows of it. He had looked down through it at the city that lay beneath, and he had seen those who came and went in the buried streets.
Stark hunkered down. For a long while he did not stir.
He did not want to go out there. He did not want to go out from the grim, warning figure of Ban Cruach with his blazing sword, into that silent valley. He was afraid, afraid of what he might see if he went there and looked down through the ice, afraid of the final dread fulfillment of his vision.
But he had come after Balin, and Balin must be out there somewhere. He did not want to go, but he was himself, and he must.
* * * * *
He went, going very softly, out toward the tower of stone. And there was no sound in all that land.
The last of the twilight had faded. The ice gleamed, faintly luminous under the stars, and there was light beneath it, a soft radiance that filled all the valley with the glow of a buried moon.
Stark tried to keep his eyes upon the tower. He did not wish to look down at what lay under his stealthy feet.
Inevitably, he looked.
The temples and the palaces glittering in the ice....
Level upon level, going down. Wells of soft light spanned with soaring bridges, slender spires rising, an endless variation of streets and crystal walls exquisitely patterned, above and below and overlapping, so that it was like looking down through a thousand giant snowflakes. A metropolis of gossamer and frost, fragile and lovely as a dream, locked in the clear, pure vault of the ice.
Stark saw the people of the city passing along the bright streets, their outlines blurred by the icy vault as things are half obscured by water. The creatures of vision, vaguely shining, infinitely evil.
He shut his eyes and waited until the shock and the dizziness left him. Then he set his gaze resolutely on the tower, and crept on, over the glassy sky that covered those buried streets.
Silence. Even the wind was hushed.
He had gone perhaps half the distance when the cry rang out.
It burst upon the valley with a shocking violence. "Stark! Stark!" The ice rang with it, curving ridges picked up his name and flung it back and forth with eerie crystal voices, and the echoes fled out whispering Stark! Stark! until it seemed that the very mountains spoke.
Stark whirled about. In the pallid gloom between the ice and the stars there was light enough to see the cairn behind him, and the dim figure atop it with the shining sword.
Light enough to see Ciara, and the dark knot of riders who had followed her through the Gates of Death.
She cried his name again. "Come back! Come back!"
The ice of the valley answered mockingly, "Come back! Come back!" and Stark was gripped with a terror that held him motionless.
She should not have called him. She should not have made a sound in that deathly
