West of Eden

he called out, and Kerrick felt the hair stir on the back of his neck.
    "It is Peremandu," Herilak said. "He ran all day, most of this night as well."
    Peremandu was conscious, but completely exhausted. They carried him to Kerrick, his toes trailing in the dust, then sat him gently on the ground. In the flickering light of the torches his skin was pale: sooty patches ringed his eyes.
    "Coming…" he said hoarsely. "Behind me… Sigurnath, dead."
    "Are there guards at the river?" Kerrick asked, and Peremandu shook his head weakly when he heard the words.
    "Not on the water. Land."
    "Run," Herilak ordered the hunters who had carried Peremandu. "Wake everyone. Get the sammadars here."
    Armun slipped out of the tent and bent over Peremandu, holding a cup of water to his mouth. He drained it greedily, gasping with the effort. His words came a bit more easily now.
    "We watched the river—but they came by land. First a dust cloud bigger than anything we had ever seen.
    There were murgu, they could not be counted, running fast, heavy feet, death-stick murgu on their backs.
    The murgu also rode another kind, bigger, faster, scouting ahead. When we ran they saw us. Killed Sigurnath. I went into the river, holding my breath, as long as I could. Swimming deep, with the current.
    When I came up they were gone. I stayed in the water a long time."
    The sammadars hurried up while he was talking, while more and more hunters gathered silently to listen.
    The torchlight flickered across their grim faces.

    "When I came out of the water they were gone. I could see the dust of their passing in the distance. They went very fast. I followed their track, wide as a river through the trampled grass, marked with much dung of the murgu. Followed until the sun was low and I could see that they had halted by the river. Then I stopped too and went no closer. The margalus has said that they do not like the night and do not go about then. Remembering this I waited until the sun had set. As soon as it was dark I circled far to the east so I would not pass near them. I did not see them again. I ran and did not stop, and I ran and I am here.
    Sigurnath is dead."
    He dropped back onto the ground, exhausted again by the effort of speaking. What he had said struck terror into the listeners' hearts for they knew that death was striding close.
    "They will attack," Kerrick said. "Soon after dawn. They know exactly where we are. They plan these things carefully. They will have stopped for the night just far enough away not to be observed, yet close enough to strike in the morning."
    "We must defend ourselves," Herilak said.
    "No! We must not stay here." Kerrick spoke the wordsquickly, almost without thought; they were driven from him by a strong emotion.
    "If we leave they will attack us while we move," Herilak said. "We will be defenseless, slaughtered as we run. It will be better to remain here where we can make a stand."
    "Hear me out," Kerrick said. "If we remain here that will be exactly what they want us to do. It is their plan to attack us in this place. You can be sure that the attack has been worked out in all details and is meant to destroy us. Now we must stop and think of the best way to survive. The beasts they ride, I have never seen or heard of them before. That means nothing. They have the resources of an entire world out there. There are strange creatures beyond counting, murgu we cannot even imagine. But now we know about them, now we are forewarned." He looked around. "We chose this place to camp because there was water and we could defend ourselves against attack from the river. Do they come by water as well? Did you see any boats?"
    "None," Peremandu said. "The river was empty. They are so many that they need no aid. Their numbers were like the birds when they gather to fly south in the autumn. Like leaves, they could not be counted."
    "Our thorn barrier will be trampled down," Kerrick said. "So will we. We must leave at once. Go north.
    We cannot remain here."
    The murmuring died away. No one wanted to speak, for all of this was too unusual, too new. They looked to their leaders. The sammadars looked at Herilak. The decision was his. His face was as grim as theirs, grimmer—for the responsibility now was his alone. He looked around at them, then straightened his back and slammed his spear butt onto the ground.
