“Yes. By finding Ahriman, the Dark One.”

“And once I find him?”

For the first time, he looked surprised. “Why, you must kill him, of course.”

I stared at Ormazd, saying nothing.

“You don’t believe what I have told you?”

I wished I could truthfully say that I didn’t. Instead, I said, “I believe you. But I don’t understand. Why can’t I remember any of this? Why…”

“Temporal shock, perhaps,” he interrupted. “Or maybe Ahriman has already reached your mind and blocked some of its capacities.”

“Some?” I asked.

“Do you know the capacities of your mind? The training we have lavished upon you? Your ability to use each hemisphere of your brain independently?”

“What?”

“Are you right-handed or left-handed?”

That took me off-guard. “I’m… ambidextrous,” I realized.

“You can write with either hand, can’t you? Play a guitar either way.”

I nodded.

“You have the ability to use both sides of your brain independently of each other,” he said. “You could run a computer and paint a landscape at the same time, using your right hand for one and your left for the other.”

That sounded ridiculous. “I could get a job as a freak in the circus, is that it?”

He smiled again. “More than that, Orion. Far more.”

“What about this Ahriman?” I demanded. “What danger does he pose to the human race?”

“He is evil itself,” Ormazd said, his golden eyes blazing up so brightly that there was no doubt in my mind of his sincerity. “He seeks to destroy the human race. He would scour the Earth clean of human life for all time, if we allow him to.”

Strangely, my mind was accepting all this. It was as if I were re-learning the tales of my childhood. Distant echoes of half-remembered stories stirred within me. But now the stories were real, no longer the legends that elders tell their children.

“If I actually came here from fifty thousand years in the future,” I said slowly, as I worked it out in my mind, “that means that the human race still exists at that time. Which in turns means that the human race was not destroyed here in the Twentieth Century.”

Ormazd sighed petulantly. “Linear thinking.”

“What does that mean?”

Leaning forward and placing his golden-skinned hands on the desktop, he explained patiently, “You did save the human race. It has already happened, in this space-time line. Fifty thousand years in the future, humankind has built a monument to you. It stands in Old Rome, not far from the dome that covers the ancientVatican.”

It was my turn to smile. “Then if I’ve already saved humanity…”

“You must still play your part,” he said. “You must still find Ahriman and stop him.”

“Suppose I refuse?”

“You can’t!” he snapped.

“How do you know?”

The light around him seemed to pulse, as if in anger. “As I told you, it has already happened — in this time line. You have found Ahriman. You have saved the human race. All that you need to do now is to play out the part that our history shows you played.”

“But if I refuse?”

“That is unthinkable.”

“If I refuse?” I insisted.

He glittered like a billion fireflies. His face became grim. “If you do not play out your predestined role — if you do not stop Ahriman — the very fabric of space-time itself will be shattered. This timeline will crack open, releasing enough energy to destroy the universe as we know it. The human race will disappear. All of space-time will be shifted to a different track, a different continuum. The planet Earth will be dissolved. This entire universe of space-time will vanish as though it had never existed.”

He was utterly convincing.

“And if I do cooperate?” I asked.

“You will find Ahriman. You will save the human race from destruction. The space-time continuum will be preserved. The universe will continue.”

“I will kill Ahriman, then?”

He hesitated a long moment before answering slowly, “No. You cannot kill him. You will stop him, prevent him from achieving his goal. But… he will kill you.”

I should have realized that when he’d told me about the monument. I was to be a dead hero. It had already happened that way.

Suddenly it was all too much for me to bear. I shot up from my chair and lunged across the broad desk, reaching for his arm. My hand went completely through Ormazd’s shimmering, gleaming image.

“Fool!” he snapped, as he faded into nothingness.

I was alone in the psychiatrist’s office. I had seen holographic projections before, but never one that looked so convincingly solid and real. My knees were weak from the weight Ormazd had placed upon me. I sank back into the leather chair, totally alone with the knowledge that the fate of all humankind depended on me. And the only human being I really wanted to save was already dead. I could not accept it. My mind refused to think about it.

Instead, I found myself searching the office for the holographic equipment that this trickster had used to project his image. I searched until dawn, but I could not find a laser or any electrovisual equipment of any kind.

For many days I simply refused to consider what Ormazd had told me. It was too fantastic, I kept telling myself. Yet all along, I knew it was true. Every atom of my being knew it was true. I was merely postponing the inevitable.

And deep within me, I burned to find the Dark One, the man who had murdered Aretha. My soul raged to seek him out and destroy him. Not for the cosmic drama that Ormazd had described to me. I wanted my hands around Ahriman’s throat for a very simple, very human reason: justice. Vengeance for my dead love.

Finally, a wisp of memory put me on Ahriman’s trail. I remembered ( remembered!) the origin of the names the golden man used: Ormazd, the god of light and truth; Ahriman, the god of darkness and death. They were from the ancient religion ofPersia, Zoroastrianism, founded by the man the ancient Greeks called Zarathustra.

So the golden one considered himself a god of light and goodness. He was at least a time traveler, if he had been telling me the truth. Was he indeed the same Ormazd who appeared to Zoroaster long millennia ago inPersia? Had he been struggling against Ahriman even then? Of course. Then and now, future and past, the track of time was becoming clear to me.

I brooded about the situation for days, not knowing what to do, waiting for some clue, some indication of how to proceed. Then a new memory stirred me, and I understood why I had been placed in this moment of time, why I had been sent to this particular company and this exact job.

I closed my eyes and recalled Tom Dempsey’s long, serious, hound-dog face. It had been at the office Christmas party last year that he had told me, a bit drunkenly:

“The Sunfire lasers, man. Those goddam’ beautiful high-power lasers. Most important thing th’ company’s doin’. Most important thing goin’ on in th’ whole fuckin’ world!”

The lasers for the thermonuclear fusion reactor. The lasers that would power a man-made sun, which in turn would provide the permanent answer to all the human race’s energy needs. The god of light made real in a world of science and technology. Where else would the Dark One strike?

It took me nearly a week to convince my superiors that the time had come for me to do a new market forecast for the laser fusion project. Continental Electronics was building the lasers for the world’s first commercial CTR — Controlled Thermonuclear Reactor. By the end of that week I was on the company jet, bound forAnn Arbor, where the fusion reactor and its associated power plant were being built. Tom Dempsey sat beside me as we watched the early winter cloudscape forming along theshoreofLake Erie, some thirty thousand feet below our speeding plane.

Tom was grinning happily at me. “First time I’ve seen you take an interest in the fusion project. I always thought you couldn’t care less about this work.”
