Kazi allowed his brows to raise for a moment, then turned to Imre. "Your large friend thinks I am very old. How old do you take me for?"

Imre was almost afraid to speak. "Thirty?" he replied hesitantly.

"The boy says thirty," Kazi looked at Nils with something like amusement. "Then why do you say I am very old?"

"I sense it."

"You can't see into my mind."

"No, I simply sense it. And if you are very old but look thirty, then it follows that you do not age."

Kazi gazed intently at Nils. "I could have you killed in an instant."

"I have died before."

Kazi's eyes narrowed. "I have heard of that belief. But if it is true, yet you do not remember from one life to the next, what use is it? Meanwhile, you are young and gifted with a great pulsing body that has much yet to enjoy. You do not know how much." Kazi paused, intent for some mental response that did not come, then went on. "And your mind may be one of the two most unusual minds that exist. It would be enormously interesting to see what could be made of it. You can be a ruler in this world if you wish, have and do almost anything you want."

"I have looked at the great glaciers in the valleys of the north," Nils replied. "It is said they are growing toward the sea and that they have grown before and covered the whole land with ice and then disappeared, time and again. Even you won't live until they melt one time, because you couldn't stand it that long. I have looked at the stars on a clear night. They are said to be so far away that from some of them the light I saw has been a thousand times a thousand years coming. So what is this you offer?"

Kazi stared at him for long seconds, then his mind shot out a command. One tall guard raised his sword and swung with all the strength of his powerful right arm and shoulder. Nils was lunging from his seat on the cushion, but the weapon moved too quickly. Imre's head struck the floor without rolling, the carpeting was so thick and soft. Nils felt sharp steel against his back and stared as Imre's body toppled slowly sideways, blood spurting from the neck.

"So. You are subject to emotion, after all," Kazi said pleasantly. "The difference is that there is no positive feedback. It flashed and died. Have you ever thought of yourself as… " He paused. There was no word for it which would have meaning for a barbarian, or for any man of this age. "As a computer?" he finished.

Nils sat, relaxed again, watching Kazi without answering.

"And where did you learn about ice ages and the distances between stars?"

"From a wise man."

"Of your own people?"

"No. My people have lost such knowledge. I learned it after I began my travels."

"And why do you believe such strange stories?"

"Because they are true."

"And you sense truth?" Kazi gazed thoughtfully at him for a long minute. "I will think about you for a while. Return to your apartment. And if you want anything-drinks, girls, someone to answer questions-strike the gong you find there. Tomorrow you will attend the games with me. You will find them interesting."

Imre's things still lay on a bench when Nils entered. He struck the gong softly, and very soon a girl appeared to stand silently. "Take these things away," he said. "Their owner is dead."

Apparently the girl understood Anglic because she bent and picked them up.

"Also," Nils added, "I would like the company of someone who can answer my questions."

"I will tell the steward," she said, her voice quiet and accented.

Nils went into his own chamber then. Its window faced west, and the evening sun shone in. He became aware of a sense of depression, and looked at it for a few seconds so that it went away. Drawing the heavy curtains he lay down and closed his eyes, seeming to fall asleep at once. But a part of him remained aware, and after a time he knew that someone was coming up the stairs to the terrace outside. It was a young woman, a psi, and she was coming to find him.

He swung his powerful legs over the side of the bed, got up and walked to the door. The sun had just set, but the western sky was so cloudless and free of haze that it showed little color other than silver blue. The girl was just outside, and stopped, facing him as his big torso blocked the way.

"You were resting; perhaps I came too soon." She phrased her thoughts in Anglic, not speaking. "I am Nephthys. My father directed me to come to you and answer your questions if I am able."

She was awesomely beautiful.

His answer was also unvoiced. "I was waiting, not resting." He stepped back into the room.

She followed, and sat gracefully on a couch. Nils had hardly needed the brief mental identification of "father" she had given him. Her color, psi, and fine-boned face indicated that she was Kazi's daughter.

Nephthys could not read Nils's interpretation, but her knowingness anticipated it. "In a sense he is not my father," her thoughts continued. "The body he wears now is that of a half-brother. But at one time he wore the body of my father-his is the mind, the ego-essence, the continuity of experience, memory and identity, that was, is, my father. It is as father that I think of him. Do you understand?"

"I'm beginning to. He does age, then, but before he becomes old, he somehow occupies a new body without… without dying, without forgetting. And he fathers a series of bodies to equip himself properly, the way the lords of the Danes and the Magyars breed special lines of horses in order to have good mounts."

She nodded. "He has two harems, small but highly select. One is of beauties, for pleasure; my mother was one of these. The other is to provide young men from which he can select a physical successor."

"And does he change bodies for special purposes, as a knight may use one horse to travel on, another for hunting and a third for battle?"

"No," she answered, half-smiling at the analogy. "The transfer is difficult, requiring days of preparation, and the drugs for both bodies are unpleasant. His emotions at such a time, and those of the other, are of men fighting with death."

Nils moved to another subject. "And I suppose he plans to march north with his armies very soon."

"How did you know?"

"He concentrated this army of horse barbarians for a reason. And he won't keep them here long because of the problems of feeding them and keeping them from fighting each other out of idleness and boredom. And he already rules these plains and all the lands to the south, while in the west the mountain tribes of the South Slavs give him tribute and slaves. And up the Duna are the Magyars, whose king has agreed to strike north and west with his army at your father's command, into the lands of the Germans and Bohemians. I learned that from the mind of the Magyar king himself. But north of here are the lands of the Ukrainians and Poles, still independent, with rich pastures and farms and large herds of cattle and horses. And a good route to western Europe; there aren't any mountains to cross. But I have only a vague idea of how many men Kazi has."

"I've heard him say he has ten thousand orcs ready to march. That doesn't include garrisons that must be left behind to control the empire. And those ten thousand are equal to twice that number of any other soldiers, in fighting effectiveness. Beyond that he has gathered twenty thousand horse barbarians. Their loyalties are to their chiefs, but he has made those chieftains his."

She stopped then, looking at and into Nils. "This place is deadly for you," she said. "Why did you come here?"

He looked intently back at her, and even her dark skin flushed, because his thoughts were clearly on her and she could not read them.

"Let me ask instead why you came here," Nils countered. "Why did your father send you instead of one of his officers who could answer questions that you can't."
