Now more and more he reached into Shannon's past, trying to find the thing that had kept him going. Genuine physical weakness, other than simple hunger, thirst and fatigue, was something he had never known, and dealing with it frustrated all the lessons he had learned as a mai. Being alien to his experience, he had assumed that it did not exist---that there was only weakness of will, and that so long as his desire held, no barrier of the flesh would ever stop him. This lesson in perspective he accepted, though grudgingly. It seemed that everything he had known in three seasons of life must be relearned, altered to fit this new reality. But his will remained undaunted. He traveled many hours into the darkness of night, until he found a small hollow of earth and root of stone at the base of a pummeled and wind torn boulder. A thin lacing of ground-snow, carried by the wind, swirled around him and whistled in its cracks, making a melancholy sound that he felt still deeper for the lassitude of his body. Here he rested, and tried not to think, until the coming of morning. The morning was much the same as the night, with only a patchy gray light to tell him when the day had come. He moved out of the shelter and walked, across shallow hills, rising in monotonous rhythm through a bleak and barren landscape. The earth was a dull and frozen brown, broken now and again by rock, or gnarled scrub, or nothing. The thin snow blew over all, trailing and whirling about in long wisps like the twisting hands of witches. He continued on for many hours, until the wind relented just long enough for him to exhaust himself in flight. He landed again, and found the earth covered intermittently with thin patches of ice, sometimes deepening and joining together into shrunken, unmoving streams, or withered oak leaves of many fingers. He continued and night came again but he did not stop. He had eaten what hard and knotted brush he could find, and there was now no lack of moisture; and though it was his mind he feared, denying it had not yet become unbearable. He rested a short time, went on the next day. And the next, walking because he could not fly, into the growing cold, and thicker snow, and ice that began to dominate the ground. Until he was alone. Time passed. * He had reached the farthest North. The world was ice, layered with snow. The wind blew the white softness above into dunes, sometimes foaming against islands of rock, huddled together in groups or branching straight like disjointed coral reefs, while its gusting blasts wrapped veils over all, swirling and howling in relentless defiance. The day lasted but four short hours, then all was swathed in darkness, so that the swirling sheets were blind and crashed over him like spray of drowning surf on the deck of a floundering ship. He was utterly alone.
