The cairn loomed up ahead, dark and high. It seemed to Stark that the brooding figure of Ban Cruach watched him coming with those shadowed eyes beneath the rusty helm. The great sword blazed between those dead, frozen hands.
The ice-folk had slowed their forward rush. They stopped and waited, well back from the cairn.
Stark reached the edge of tumbled rock. He felt the first warm flare of the force-waves in his blood, and slowly the chill began to creep out from his bones. He climbed, scrambling upward over the rough stones of the cairn.
Abruptly, then, at Ban Cruach's feet, he slipped and fell. For a second it seemed that he could not move.
His back was turned toward the ice-folk. His body was bent forward, and shielded so, his hands worked with feverish speed.
From his cloak he tore a strip of cloth. From the iron boss he took the glittering lens, the talisman of Ban Cruach. Stark laid the lens against his brow, and bound it on.
The remembered shock, the flood and sweep of memories that were not his own. The mind of Ban Cruach thundering its warning, its hard-won knowledge of an ancient, epic war....
He opened his own mind wide to receive those memories. Before he had fought against them. Now he knew that they were his one small chance in this swift gamble with death. Two things only of his own he kept firm in that staggering tide of another man's memories. Two names—Ciara and Balin.
He rose up again. And now his face had a strange look, a curious duality. The features had not changed, but somehow the lines of the flesh had altered subtly, so that it was almost as though the old unconquerable king himself had risen again in battle.
He mounted the last step or two and stood before Ban Cruach. A shudder ran through him, a sort of gathering and settling of the flesh, as though Stark's being had accepted the stranger within it. His eyes, cold and pale as the very ice that sheathed the valley, burned with a cruel light.
He reached and took the sword, out of the frozen hands of Ban Cruach.
As though it were his own, he knew the secret of the metal rings that bound its hilt, below the ball of crystal. The savage throb of the invisible radiation beat in his quickening flesh. He was warm again, his blood running swiftly, his muscles sure and strong. He touched the rings and turned them.
The fan-shaped aura of force that had closed the Gates of Death narrowed in, and as it narrowed it leaped up from the blade of the sword in a tongue of pale fire, faintly shimmering, made visible now by the full focus of its strength.
Stark felt the wave of horror bursting from the minds of the ice-folk as they perceived what he had done. And he laughed.
His bitter laughter rang harsh across the valley as he turned to face them, and he heard in his brain the shuddering, silent shriek that went up from all that gathered company....
"Ban Cruach! Ban Cruach has returned!"
They had touched his mind. They knew.
* * * * *
He laughed again, and swept the sword in a flashing arc, and watched the long bright blade of force strike out more terrible than steel, against the rainbow bodies of the shining ones.
They fell. Like flowers under a scythe they fell, and all across the ice the ones who were yet untouched turned about in their hundreds and fled back toward the tower.
Stark came leaping down the cairn, the talisman of Ban Cruach bound upon his brow, the sword of Ban Cruach blazing in his hand.
He swung that awful blade as he ran. The force-beam that sprang from it cut through the press of creatures fleeing before him, hampered by their own numbers as they crowded back through the archway.
He had only a few short seconds to do what he had to do.
Rushing with great strides across the ice, spurning the withered bodies of the dead.... And then, from the glooming darkness that hovered around the tower of stone, the black cold beam struck down.
Like a coiling whip it lashed him. The deadly numbness invaded the cells of his flesh, ached in the marrow of his bones. The bright force of the sword battled the chill invaders, and a corrosive agony tore at Stark's inner body where the antipathetic radiations waged war.
His steps faltered. He gave one hoarse cry of pain, and then his limbs failed and he went heavily to his knees.
Instinct only made him cling to the sword. Waves of blinding anguish racked him. The coiling lash of darkness encircled him, and its touch was the abysmal cold of outer space, striking deep into his heart.
Hold the sword close, hold it closer, like a shield. The pain is great, but I will not die unless I drop the sword.
Ban Cruach the mighty had fought this fight before.
Stark raised the sword again, close against his body. The fierce pulse of its brightness drove back the cold. Not far, for the freezing touch was very strong. But far enough so that he could rise again and stagger on.
The dark force of the tower writhed and licked about him. He could not escape it. He slashed it in a blind fury with the blazing sword, and where the forces met a flicker of lightning leaped in the air, but it would not be beaten back.
He screamed at it, a raging cat-cry that was all Stark, all primitive fury at the necessity of pain. And he forced himself to run, to drag his tortured body faster across the ice. Because Ciara is dying, because the dark cold wants me to stop....
The ice-folk jammed and surged against the archway, in a panic hurry to take refuge far below in their many-levelled city. He raged at them, too. They were part of the cold, part of the pain. Because of them Ciara and Balin were dying. He sent the blade of force lancing among them, his hatred rising full tide to join the hatred of Ban Cruach that lodged in his mind.
Stab and cut and slash with the long terrible beam of brightness. They fell and fell, the hideous shining folk, and Stark sent the light of Ban Cruach's weapon sweeping through the tower itself, through the openings that were like windows in the stone.
Again and again, stabbing through those open slits as he ran. And suddenly the dark beam of force ceased to move. He tore out of it, and it did not follow him, remaining stationary as though fastened to the ice.
The battle of forces left his flesh. The pain was gone. He sped on to the tower.
He was close now. The withered bodies lay in heaps before the arch. The last of the ice-folk had forced their way inside. Holding the sword level like a lance, Stark leaped in through the arch, into the tower.
* * * * *
The shining ones were dead where the destroying warmth had touched them. The flying spiral ribbons of ice were swept clean of them, the arching bridges and the galleries of that upper part of the tower.
They were dead along the ledge, under the control bank. They were dead across the mechanism that spun the frosty doom around Ciara and Balin. The whirling disc still hummed.
Below, in that stupendous well, the crowding ice-folk made a seething pattern of color on the narrow ways. But Stark turned his back on them and ran along the ledge, and in him was the heavy knowledge that he had come too late.
The frost had thickened around Ciara and Balin. It encrusted them like stiffened lace, and now their flesh was overlaid with a diamond shell of ice.
Surely they could not live!
He raised the sword to smite down at the whirring disc, to smash it, but there was no need. When the full force of that concentrated beam struck it, meeting the focus of shadow that it held, there was a violent flare of light and a shattering of crystal. The mechanism was silent.
The glooming veil was gone from around
