do as I say. Come to this workbench."
    Kerrick could see what they were doing, but had no idea why. Essag used a pad to moisten the ball of his thumb, then Ikemei pierced it suddenly with a sharp object. Kerrick was surprised that he felt nothing, even when Ikemei squeezed great drops of blood from his thumb. Essag caught them in little containers which sealed themselves when she squeezed their tops. Then his arm was placed flat on the surface and rubbed with another pad that first felt cool, then numb.
    "Look there," Ikemei said, pointing high on the wall. Kerrick looked up and saw nothing. When he looked back he saw that while he had been distracted she had used a string-blade to slice away a thin layer of his skin. There was no sensation of pain. The small drops of blood that began to well up were covered by the adhesive bandage of a nefmakel.
    Kerrick could not contain his curiosity any longer. "You have taken some of my skin and my blood.
    Why?"
    "An ustuzou with curiosity," Ikemei said, signing him to lie flat on a low bench. "There is no end to wonders in this world. I am examining your body, that is what I am doing. Those colored sheets there will make a chromatographic examination, while those precipitating columns, those transparent tubes, will discover other secrets of your chemistry. Satisfied?"
    Kerrick was silent, understanding nothing. Ikemei placed a lumpish gray creature on his chest and prodded it to life.
    "And now this thing is generating ultrasound to look inside your body. When it is finished we will know all about you. Get up. We are done. A fargi will show you the way to return."
    Ikemei looked on and marveled as the door closed behind Kerrick and Inlènu*. "A talking animal. For the first time I am eager to get to Alpèasak. I have heard that ustuzou lifeforms are varied and interesting there. I look forward with great interest to seeing them for myself. Orders."
    "I hear, Ikemei," Essag said.
    "Do a complete series of sera tests, all the metabolic tests, give me a complete picture of this creature's biology. Then the real work begins."

    Ikemei turned to the workbench and almost as an afterthought said, "We must find out all we can about its metabolic processes. We have been ordered to find parasites, predators, anything that will cause specific damage to this species." She wriggled with distress as she said this and her assistant shared her discomfort. Ikemei gestured her to silence before she could speak.
    "I know your thoughts and share them. We build life, we don't destroy it. But these particular ustuzou have become a menace and a danger. They must be driven away. That is it, driven away. They will leave and not bother the new city when they see they are in danger. We shall not kill them, we will just drive them away."
    She spoke with all the sincerity that she could muster. Yet she and Essag shared a growing fear that darker things were being planned. Their respect for life, all life, warred with their sense of survival and their muscles twitched spasmodically with the silent conflict.
    CHAPTER TWENTY-TWO
    As the great doors were swung slowly shut the sounds of the ambesed outside began to grow quiet.
    Silence filled the room when they had closed all the way. Vaintè had scarcely noted the details of the doors before, though she had been in this chamber many times in the past. Her attention was drawn to them now. They were intricately carved with a variety of intertwined plants and animals, these in turn had then been inset with shining metal and gemstones. They were just one more of the luxuries and pleasures of this ancient city that were taken for granted by the Yilanè who dwelled here. That she had once also taken for granted. How different this was from new-grown Alpèasak where there were scarcely any doors at all—while the few that did exist might still be damp with the sap of their growth. Everything there was crude and quickly grown, new and green, in direct contrast to this cultured city, old and staid. It was brash of her to be here, Eistaa of a wilderness city come to stand before those who ruled in timeless Inegban*.
    Vaintè rejected this line of thought instantly. There was no shame to newness, no need for her to feel inferior here in this great city. Inegban*, ancient, rich—but certainly doomed, there could be no doubting that. These trees would die, cold mists and dead leaves would blow through the empty city, these ponderous doors
