Winter in Eden

look!"
    Someone in the ikkergak to their left was waving a dark shape over his head. Kalaleq picked up a skin and passed the signal on down the line as they heeled over to follow the other turning ikkergak. The herd had been seen: the hunt was on.
    The first ikkergaks tacked while they waited for the others to catch up—then all of them moved west together.
    "There they are," Kalaleq shouted. "How beautiful—I have never seen anything that beautiful!"
    To Kerrick they were just dark lumps against the ice—but they were food and shelter, life itself to the Paramutan. Their entire existence depended on the ularuaq, and to find them again they had crossed the ocean, from continent to continent. Now was the time when they must succeed.
    Closer they came and closer, until Kerrick could see the great dark backs of the beasts as they moved along the wall of ice. They had blunt heads and what looked like thick lips. With them they seized the qunguleq and tore great streamers free. They reminded him of uruketo, they were as large, only they lacked the high dorsal fin. Every now and again one of them would surge high out of the water and crash back with a tremendous splash. The ikkergaks drew closer and angled toward the far side of the pack and began to separate. Kalaleq nodded in appreciation of the maneuver.
    "Get in front, let them see, make them come back toward us." He pointed at the other ikkergak which, like them, had dropped its sail and was rocking motionless in the waves.
    The others hurried away, letting out their sails fully to reach the pack as quickly as they could, angling for position. The great creatures grazed steadily, seemingly indifferent to the ikkergaks that grew ever closer.
    Their own craft rocked back and forth on the waves, the sail flapping loosely. The tension grew and Kalaleq shook the spear and bounced back and forth from one foot to the other.
    "They are coming!" someone shouted.

    Everything seemed to happen at once after that—and Kerrick jumped back out of the way. The sail was run up and lashed tight while the steerman—facing the bow for the first time—headed toward the approaching pack which had taken fright and was now fleeing from the other ikkergaks. Kalaleq stood ready in the bow, solid and unmoving and apparently ignoring all the shouted advice. The dark forms of the ularuaq plunged toward them.
    "Now!" Kalaleq shouted. "Go about!"
    In a single frenzied spasm of effort the steerman pushed hard on his oar while the others hauled on the lines that swung the sail to the other side of the mast. It flapped and cracked—then filled again. Moments later they were moving again on the opposite tack. Away from the ularuaq, angling across before them.
    The reason for the maneuver was soon obvious. The ikkergak was no match for the rushing pack, could never have caught up with them. But as the giant sea creatures overtook them their relative speed was slowed and Kalaleq could select his victim. He did this calmly, signing to the steerman with his hands which direction he wanted to go, ignoring all the advice about size and suitability from the rest of the crew.
    They were in amongst them now, sleek wet forms moving by on both sides.
    "Now!" Kalaleq cried—and stabbed his spear into a bladder that hung by a thong over the bow of the ikkergak, just beside him. The spearpoint came out black and dripping and a repulsive odor washed back from the burst bladder. The ikkergak rocked as it bumped the back of the ularuaq.
    Kalaleq plunged the spear down with all of his strength, deep into the creature's hide, then jumped away as the coil of line attached to it began to run quickly over the side. The stench from the punctured bladder was unbelievable and Kerrick lurched to the side and threw up. Through his tears he saw Kalaleq cutting the thong—the bladder dropped into the sea and was swept away.
    With this done, Kalaleq kicked overboard the inflated skin just as the last of the line paid out. The skin bubbled away through the water, secured to the line, and the ikkergak turned and followed it.
    Kalaleq climbed the mast again and shouted down instructions. If they lost sight of the inflated skin the whole operation would fail.
    The steerman glanced at Kerrick and laughed. "Strong poison, good and strong. Make you bring up all your food, just smelling it. Even a ularuaq cannot live long with that poison in it, you'll see."
    He was right; soon after this they came
