Part 2

"What are they?"

He described the weapons of his day. But Quiana's smile was a little scornful when he finished.

"We of Zha have passed beyond the use of missile weapons--even such missiles as bullets or rays. Nor could they touch my Enemy. No, we can destroy in ways that require no--no beams or explosives. No, Dantan, you speak in terms of your own universe. We have no common ground. It is a pity that time eddied between Sanfel and me, but eddy it did, and I am helpless now. And the Enemy will be upon me soon. Very soon."

* * * * *

She let her shoulders sag and resignation dimmed the remembered vividness of her face. Dantan looked up at her grimly, muscles riding his set jaw. It was almost intolerable, this facing her again in need, and again helpless, and himself without power to aid. It had been bad enough that first time, to learn long afterward that she had died at enemy hands while he was too far away to protect her. But to see it all take place again before his very eyes!

"There must be a way," he said, and his hand gripped the lever marked "door" in the ancient tongue.

"Wait!" Quiana's voice was urgent.

"What would happen?"

"The door would open. I could enter your world, and you mine."

"Why can't you leave, then, and wait until it's safe to go back?"

"I have tried that," Quiana said. "It will never be safe. The Enemy waited too. No, it must come, in the end, to a battle--and I shall not win that fight. I shall not see my own people or my own land again, and I suppose I must face that knowledge. But I did hope, when I heard Sanfel's signal sound again...." She smiled a little. "I know you would help me if you could, Dantan. But there is nothing to be done now."

"I'll come in," he said doggedly. "Maybe there's something I could do."

"You could not touch him. Even now there's danger. He was very close when I heard that signal. This is his territory. When I heard the bell and thought Sanfel had returned with a weapon for me, I dared greatly in coming here." Her voice died away; a withdrawn look veiled her eyes from him.

After a long silence she said, "The Enemy is coming. Turn off the screen, Dantan. And goodbye."

"No," he said. "Wait!" But she shook her head and turned away from him, her thin robe swirling, and moved off like a pale shadow into the dim, shadowless emptiness of the background. He stood watching helplessly, feeling all the old despair wash over him a second time as the girl he loved went alone into danger he could not share. Sometimes as she moved away she was eclipsed by objects he could not see--trees, he thought, or rocks, that did not impinge upon his eyes through the protective helmet. A strange world indeed Zha must be, whose very rocks and trees were too alien for human eyes to look upon in safety.... Only Quiana grew smaller and smaller upon the screen, and it seemed to Dantan as though a cord stretched between them, pulling thinner and thinner as she receded into danger and distance.

It was unbearable to think that the cord might break--break a second time....

Far away something moved in the cloudy world of Zha. Tiny in the distance though it was, it was unmistakably not human. Dantan lost sight of Quiana. Had she found some hiding place behind some unimaginable outcropping of Zha's terrain?

The Enemy came forward.

It was huge and scaled and terrible, human, but not a human; tailed, but no beast; intelligent, but diabolic. He never saw it too clearly, and he was grateful to his helmet for that. The polarized glass seemed to translate a little, as well as to blot out. He felt sure that this creature which he saw--or almost saw--did not look precisely as it seemed to him upon the screen. Yet it was easy to believe that such a being had sprung from the alien soil of Zha. There was nothing remotely like it on any of the worlds he knew. And it was hateful. Every line of it made his hackles bristle.

It carried a coil of brightly colored tubing slung over one grotesque shoulder, and its monstrous head swung from side to side as it paced forward into the screen like some strange and terrible mechanical toy. It made no sound, and its progress was horrible in its sheer relentless monotony.

* * * * *

Abruptly it paused. He thought it had sensed the girl's presence, somewhere in hiding. It reached for the coil of tubing with one malformed--hand?

"Quiana," it said--its voice as gentle as a child's.

Silence. Dantan's breathing was loud in the emptiness.

"Quiana?" The tone was querulous now.

"Quiana," the monster crooned, and swung about with sudden, unexpected agility. Moving with smooth speed, it vanished into the clouds of the background, as the girl had vanished. For an eternity Dantan watched colored emptiness, trying to keep himself from trembling.

Then he heard the voice again, gentle no longer, but ringing like a bell with terrible triumph, "_Quiana!_"

And out of the swirling clouds he saw Quiana break, despair upon her face, her sheer garments streaming behind her. After her came the Enemy. It had unslung the tube it wore over its shoulder, and as it lifted the weapon Quiana swerved desperately aside. Then from the coil of tubing blind lightning ravened.

Shattering the patternless obscurity, the blaze of its color burst out, catching Quiana in a cone of expanding, shifting brilliance. And the despair in her eyes was suddenly more than Dantan could endure.

His hand struck out at the lever marked "door"; he swung it far over and the veil that had masked the screen was gone. He vaulted up over its low threshold, not seeing anything but the face and the terror of Quiana. But it was not Quiana's name he called as he leaped.

He lunged through the Door onto soft, yielding substance that was unlike anything he had ever felt underfoot before. He scarcely knew it. He flung himself forward, fists clenched, ready to drive futile blows into the monstrous mask of the Enemy. It loomed over him like a tower, tremendous, scarcely seen through the shelter of his helmet--and then the glare of the light-cone caught him.

It was tangible light. It flung him back with a piledriver punch that knocked the breath from his body. And the blow was psychic as well as physical. Shaking and reeling from the shock, Dantan shut his eyes and fought forward, as though against a steady current too strong to breast very long. He felt Quiana beside him, caught in the same dreadful stream. And beyond the source of the light the Enemy stood up in stark, inhuman silhouette.

He never saw Quiana's world. The light was too blinding. And yet, in a subtle sense, it was not blinding to the eyes, but to the mind. Nor was it light, Dantan thought, with some sane part of his mind. Too late he remembered Quiana's warning that the world of Zha was not Mars or Earth, that in Zha even light was different.

Cold and heat mingled, indescribably bewildering, shook him hard. And beyond these were--other things. The light from the Enemy's weapon was not born in Dantan's universe, and it had properties that light should not have. He felt bare, emptied, a hollow shell through which radiance streamed.

For suddenly, every cell of his body was an eye. The glaring brilliance, the intolerable vision beat at the foundations of his sanity. Through him the glow went pouring, washing him, nerves, bone, flesh, brain, in floods of color that were not color, sound that was not sound, vibration that was spawned in the shaking hells of worlds beyond imagination.

It inundated him like a tide, and for a long, long, timeless while he stood helpless in its surge, moving within his body and without it, and within his mind and soul as well. The color of stars thundered in his brain. The crawling foulness of unspeakable hues writhed along his nerves so monstrously that he felt he could never cleanse himself of that obscenity.

And nothing else existed--only the light that was not light, but blasphemy.

Then it began to ebb ... faded ... grew lesser and lesser, until--Beside him he could see Quiana now. She was no longer stumbling in the cone of light, no longer shuddering and wavering in its violence, but standing erect and facing the Enemy, and from her eyes--something--poured.

Steadily the cone of brilliance waned. But still its glittering, shining foulness poured through Dantan. He felt himself weakening, his senses fading, as the tide of dark horror mounted through his brain.

And covered him up with its blanketing immensity.

* * * * *

He was back in the laboratory, leaning against the wall and breathing in deep, shuddering draughts. He did not remember stumbling through the Door again, but he was no longer in Zha. Quiana stood beside him, here upon the Martian soil of the laboratory. She was watching him with a strange, quizzical look in her eyes as he slowly fought back to normal, his heart quieting by degrees, his breath becoming evener. He felt drained, exhausted, his emotions cleansed and purified as though by baths of flame.

Presently he reached for the clasp that fastened his clumsy armor. Quiana put out a quick hand, shaking her head.

"No," she said, and then stared at him again for a long moment without speaking. Finally, "I had not known--I did not think this could be done. Another of my own race--yes. But you, from Mars--I would not have believed that you could stand against the Enemy for a moment, even with your armor."

"I'm from Earth, not Mars. And I didn't stand long."

"Long enough." She smiled faintly. "You see now what happened? We of Zha can destroy without weapons, using only the power inherent in our bodies. Those like the Enemy have a little of that power too, but they need mechanical devices to amplify it. And so when you diverted the Enemy's attention and forced him to divide his attack between us--the pressure upon me was relieved, and I could destroy him. But I would not have believed it possible."

"You're safe now," Dantan said, with no expression in voice or face.

"Yes. I can return."

"And you will?"

"Of course I shall."

"We are more alike than you had realized."

She looked up toward the colored curtain of the screen. "That is true. It is not the complete truth, Dantan."

He said, "I love you--Quiana." This time he called her by name.

Neither of them moved. Minutes went by silently.

Quiana said, as if she had not heard him, "Those who followed you are here. I have been listening to them for some time now. They are trying to break through the door at the top of the shaft."

He took her hand in his gloved grasp. "Stay here. Or let me go back to Zha with you. Why not?"

"You could not live there without your armor."

"Then stay."

Quiana looked away, her eyes troubled. As Dantan moved to slip off his helmet her hand came up again to stop him.

"Don't."

"Why not?"

For answer she rose, beckoning for him to follow. She stepped across the threshold into the shaft and swiftly began to climb the pegs toward the surface and the hammering of the Redhelms up above. Dantan, at her gesture, followed.

Over her shoulder she said briefly,

"We are of two very different worlds. Watch--but be careful." And she touched the device that locked the oval door.

It slipped down and swung aside.

* * * * *

Dantan caught one swift glimpse of Redhelm heads dodging back to safety. They did not know, of course, that he was unarmed. He reached up desperately, trying to pull Quiana back but she slipped aside and sprang lightly out of the shaft into the cool gray light of the Martian morning.

Forgetting her warning, Dantan pulled himself up behind her. But as his head and shoulders emerged from the shaft he stopped, frozen. For the Redhelms were falling. There was no mark upon them, yet they fell....

She did not stir, even when the last man had stiffened into rigid immobility. Then Dantan clambered up and without looking at Quiana went to the nearest body and turned it over. He could find no mark. Yet the Redhelm was dead.

"That is why you had to wear the armor," she told him gently. "We are of different worlds, you and I."

He took her in his arms--and the soft resilience of her was lost against the stiffness of the protective suit. He would never even know how her body felt, because of the armor between them.... He could not even kiss her--again. He had taken his last kiss of the mouth so like Quiana's mouth, long years ago, and he would never kiss it again. The barrier was too high between them.

"You can't go back," he told her in a rough, uneven voice. "We _are_ of the same world, no matter what--no matter how--You're no stranger to me, Quiana!"

She looked up at him with troubled eyes, shaking her head, regret in her voice.

"Do you think I don't know why you fought for me, Dantan?" she asked in a clear voice. "Did you ever stop to wonder why Sanfel risked so much for me, too?"

He stared down at her, his brain spinning, almost afraid to hear what she would say next. He did not want to hear. But her voice went on inexorably.

"I cheated you, Dantan. I cheated Sanfel yesterday--a thousand years ago. My need was very great, you see--and our ways are not yours. I knew that no man would fight for a stranger as I needed a man to fight for me."

He held her tightly in gloved hands that could feel only a firm body in their grasp, not what that body was really like, nothing about it except its firmness. He caught his breath to interrupt, but she went on with a rush.

"I have no way of knowing how you see me, Dantan," she said relentlessly. "I don't know how Sanfel saw me. To each of you--because I needed your help--I wore the shape to which you owed help most. I could reach into your minds deeply enough for that--to mould a remembered body for your eyes. My own shape is--different. You will never know it." She sighed. "You were a brave man, Dantan. Braver and stronger than I ever dreamed an alien could be. I wish--I wonder--Oh, let me go! Let me go!"

She whirled out of his grasp with sudden vehemence, turning her face away so that he could not see her eyes. Without glancing at him again she bent over the shaft and found the topmost pegs, and in a moment was gone.

Dantan stood there, waiting. Presently he heard the muffled humming of a muted bell, as though sounding from another world. Then he knew that there was no one in the ancient laboratory beneath his feet.

He shut the door carefully and scraped soil over it. He did not mark the place. The dim red spot of the sun was rising above the canyon wall. His face set, Dantan began walking toward the distant cavern where his aircar was hidden. It was many miles away, but there was no one to stop him, now.

He did not look back.
