There was one change of which Ross was not aware but which might have startled both Ashe and McNeil. Ross Murdock had indeed died under that blow which had left him unconscious beside the river. The young man whom Frigga had drawn back to sense and a slow recovery was Rossa of the Beaker people. This same Rossa nursed a hot desire for vengeance against those who had struck him down and captured his kinsmen, a feeling which the family tribe who had rescued him could well understand. There was the same old urgency pushing him to try his strength now, to keep to his feet even when they were unsteady. His bow was gone, but Ross spent hours fashioning another, and he traded his copper bracelet for the best dozen arrows in Ulffa's camp. The jet pin from his cloak he presented to Frigga with all his gratitude. Now that his strength was coming back he could not rest easy in the camp. He was ready to leave, even though the gashes on his head were still tender to the touch. Ulffa indulgently planned a hunt southward, and Rossa took the trail with the tribesmen. He broke with the clan hunters when they turned aside at the beginning of the taboo land. Ross, his own mind submerged and taken over by his Beaker cover, hesitated too. Yet he could not give up, and the others left him there, his eyes on the forbidden heights, unhappy and tormented by more than the headaches which still came and went with painful regularity. In the mountains lay what he sought--a hidden something within his brain told him that over and over--but the mountains were taboo, and he should not venture into them. How long he might have hesitated there if he had not come upon the trail, Ross did not know. But on the day after the hunters of Ulffa's clan left, a glint of sunlight striking between two trees pointed out a woodsman's blaze on a third tree trunk. The two halves of Ross's memory clicked together for an instant as he examined that cut. He knew that it marked a trace and he pushed on, hunting a second cut and then a third. Convinced that these would lead him into the unknown territory, Ross's desire to explore overcame the grafted superstitions of his briefing. There were other signs that this was an often-traveled route: a spring cleared of leaves and walled with stone, a couple of steps cut in the turf on a steep slope. Ross moved warily, alert to any sound. He might not be an expert woodsman, but he was learning fast, perhaps the faster because his false memories now supplanted the real ones. That night he built no fire, crawling instead into the heart of a rotted log to sleep, awakening once to the call of a wolf and another time at the distant crash of a dead tree yielding to wind. In the morning he was about to climb back to the trail he had prudently left the night before when he saw five bearded, fur-clad men looking much the same as Ulffa's people. Ross hugged the earth and watched them pass out of sight before he followed.
