A heavy dull continuous thunder marked the approach of the herd. From where Yuli lay against his father, the three species of animal could be distinguished only because he knew what to look for. They all merged with one another in the heavy mottled light. The black cloud-front had advanced more rapidly than the herd, and now covered Batalix entirely: that brave sentinel would not be seen again for days. A rumpled carpet of animals rolled across the land, its individual movements no more distinguishable than currents in a turbulent river.
Mist hung over the animals, further shrouding them. It comprised sweat, heat, and small winged biting insects able to procreate only in the heat from the burly-hoofed flock.
Breathing faster, Yuli looked again and—behold!—the creatures in the forefront were already confronting the banks of the snowbound Vark. They were near, they were coming nearer—the world was one inescapable teeming animal. He flicked his head to look in appeal at his father. Although he saw his son’s gesture, Alehaw remained rigidly staring ahead, teeth gritted, eyes clenched against the cold under his heavy eye ridges.
“Still,” he commanded.
The tide of life surged along the riverbanks, flowed over, cascaded over the hidden ice. Some creatures, lumbering adults, skipping fauns, fell against concealed tree trunks, dainty legs kicking furiously before they were trampled under the pressure of the march.
Individual animals could now be picked out. They carried their heads low. Their eyes were staring, white-rimmed. Thick green trails of saliva hung from many a mouth. The cold froze the steam from their upthrust nostrils, streaking ice across the fur of their skulls. Most beasts laboured, in poor condition, their coats covered with mud, excrement, and blood, or hanging loose in strips, where a neighbour’s horns had stabbed and torn them.
The biyelks in particular, striding surrounded by their lesser brethren, their shoulders enormous with grey-bunched fur, walked with a kind of controlled unease, their eyes rolling as they heard the squeals of those who fell, and understood that some kind of danger, towards which they were inevitably to progress, threatened ahead.
The mass of animals was crossing the frozen river, churning snow. Their noise came plain to the two watchers, not solely the sound of their hoofs but the rasp of their breath, and a continued chorus of grunts, snorts, and coughs, a click of horn against horn, the sharp rattle of ears being shaken to dislodge ever persistent flies.
Three biyelks stepped forth together on the frozen river. With sharp resounding cracks, the ice broke. Shards of it almost a metre thick reared up into view as the heavy animals fell forward. Panic seized the yelk. Those on the ice attempted to scatter in all directions. Many stumbled and were lost under more animals. The cracking spread. Water, grey and fierce, jetted into the air—fast and cold, the river was still flowing. It rushed and broke and foamed, as if glad to be free, and the animals went down into it with their months open, bellowing.
Nothing deterred the oncoming animals. They were as much a natural force as the river. They flowed ever on, obliterating their companions who stumbled, obliterating too the sharp wounds opened in the Vark, bridging it with tumbled bodies, until they surged up the near bank.
Now Yuli raised himself on to his knees and lifted his ivory spear, his eyes blazing. His father seized his arm and dragged him down.
“See, phagors, you fool,” he said, giving his son a furious, contemptuous glare, and stabbing ahead with his spear to indicate danger.
Shaken, Yuli sank down again, as much frightened of his father’s wrath as by the thought of phagors.
The yelk herd pressed about their outcrop of rock, lurching by on either side of its crumbling base. The cloud of flies and stinging things that sang about their twitching backs now enveloped Yuli and Alehaw, and it was through this veil that Yuli stared, trying to get a sight of phagors. At first he discerned none.
Nothing was to be seen ahead but the avalanche of shaggy life, driven by compulsions no man understood. It covered the frozen river, it covered the banks, it covered the grey world back to the far horizon, where it tucked itself under the dun clouds like a rug under a pillow. Hundreds of thousands of animals were involved, and the midges hung above them in a continuous black exhalation.
