Philip Pullman - The Golden Compass

There was no need to ask which way to go: the tracks of the sledge led straight out from the courtyard and over the plain, and lorek leaped forward to follow them. His motion was now so much a part of Lyra's being that to sit balanced was entirely automatic. He ran over the thick snowy mantle on the rocky ground faster than he'd ever done, and the armor plates shifted under her in a regular swinging rhythm.

Behind them, the other bears paced easily, pulling the fire hurler with them. The way was clear, for the moon was high and the light it cast over the snowbound world was as bright as it had been in the balloon: a world of bright silver and profound black. The tracks of Lord Asriel's sledge ran straight toward a range of jagged hills, strange stark pointed shapes jutting up into a sky as black as the alethiometer's velvet cloth. There was no sign of the sledge itself—or was there a feather touch of movement on the flank of the highest peak? Lyra peered ahead, straining her eyes, and Pantalaimon flew as high as he could and looked with an owl's clear vision.

«Yes,» he said, on her wrist a moment later; «it's Lord Asriel, and he's lashing his dogs on furiously, and there's a boy in the back….»

Lyra felt lorek Byrnison change pace. Something had caught his attention. He was slowing and lifting his head to cast left and right.

«What is it?» Lyra said.

He didn't say. He was listening intently, but she could hear nothing. Then she did hear something: a mysterious, vastly distant rustling and crackling. It was a sound she had heard before: the sound of the Aurora. Out of nowhere a veil of radiance had fallen to hang shimmering in the northern sky. All those unseen billions and trillions of charged particles, and possibly, she thought, of Dust, conjured a radiating glow out of the upper atmosphere. This was going to be a display more brilliant and extraordinary than any Lyra had yet seen, as if the Aurora knew the drama that was taking place below, and wanted to light it with the most awe-inspiring effects.

But none of the bears were looking up: their attention was all on the earth. It wasn't the Aurora, after all, that had caught lorek's attention. He was standing stock-still now, and Lyra slipped off his back, knowing that his senses needed to cast around freely. Something was troubling him.

Lyra looked around, back across the vast open plain leading to Lord Asriel's house, back toward the tumbled mountains they'd crossed earlier, and saw nothing. The Aurora grew more intense. The first veils trembled and raced to one side, and jagged curtains folded and unfolded above, increasing in size and brilliance every minute; arcs and loops swirled across from horizon to horizon, and touched the very zenith with bows of radiance. She could hear more clearly than ever the immense singing hiss and swish of vast intangible forces.

«Witches!» came a cry in a bear voice, and Lyra turned in joy and relief.

But a heavy muzzle knocked her forward, and with no breath left to gasp she could only pant and shudder, for there in the place where she had been standing was the plume of a green-feathered arrow. The head and the shaft were buried in the snow.

Impossible.! she thought weakly, but it was true, for another arrow clattered off the armor of lorek, standing above her. These were not Serafina Pekkala's witches; they were from another clan. They circled above, a dozen of them or more, swooping down to shoot and soaring up again, and Lyra swore with every word she knew.

lorek Byrnison gave swift orders. It was clear that the bears were practiced at witch fighting, for they had moved at once into a defensive formation, and the witches moved just as smoothly into attack. They could only shoot accurately from close range, and in order not to waste arrows they would swoop down, fire at the lowest part of their dive, and turn upward at once. But when they reached the lowest point, and their hands were busy with bow and arrow, they were vulnerable, and the bears would explode upward with raking paws to drag them down. More than one fell, and was quickly dispatched.

Lyra crouched low beside a rock, watching for a witch dive. A few shot at her, but the arrows fell wide; and then Lyra, looking up at the sky, saw the greater part of the witch flight peel off and turn back.

If she was relieved by that, her relief didn't last more than a few moments. Because from the direction in which they'd flown, she saw many others coming to join them; and in midair with them there was a group of gleaming lights; and across the broad expanse of the Svalbard plain, under the radiance of the Aurora, she heard a sound she dreaded. It was the harsh throb of a gas engine. The zeppelin, with Mrs. Coulter and her troops on board, was catching up.

lorek growled an order and the bears moved at once into another formation. In the lurid flicker from the sky Lyra watched as they swiftly unloaded their fire hurler. The advance guard of the witch flight had seen them too, and began to swoop downward and rain arrows on them, but for the most part the bears trusted to their armor and worked swiftly to erect the apparatus: a long arm extending upward at an angle, a cup or bowl a yard across, and a great iron tank wreathed in smoke and steam.

As she watched, a bright flame gushed out, and a team of bears swung into practiced action. Two of them hauled the long arm of the fire thrower down, another scooped shovelfuls of fire into the bowl, and at an order they released it, to hurl the flaming sulfur high into the dark sky.

The witches were swooping so thickly above them that three fell in flames at the first shot alone, but it was soon clear that the real target was the zeppelin. The pilot either had never seen a fire hurler before, or was underestimating its power, for he flew straight on toward the bears without climbing or turning a fraction to either side.

Then it became clear that they had a powerful weapon in the zeppelin too: a machine rifle mounted on the nose of the gondola. Lyra saw sparks flying up from some of the bears' armor, and saw them huddle over beneath its protection, before she heard the rattle of the bullets. She cried out in fear.

«They're safe,» said lorek Byrnison. «Can't pierce armor with little bullets.»

The fire thrower worked again: this time a mass of blazing sulfur hurtled directly upward to strike the gondola and burst in a cascade of flaming fragments on all sides. The zeppelin banked to the left, and roared away in a wide arc before making again for the group of bears working swiftly beside the apparatus. As it neared, the arm of the fire thrower creaked downward; the machine rifle coughed and spat, and two bears fell, to a low growl from lorek Byrnison; and when the aircraft was nearly overhead, a bear shouted an order, and the spring-loaded arm shot upward again.

This time the sulfur hurtled against the envelope of the zeppelin's gas bag. The rigid frame held a skin of oiled silk in place to contain the hydrogen, and although this was tough enough to withstand minor scratches, a hundredweight of blazing rock was too much for it. The silk ripped straight through, and sulfur and hydrogen leaped to meet each other in a catastrophe of flame.

At once the silk became transparent; the entire skeleton of the zeppelin was visible, dark against an inferno of orange and red and yellow, hanging in the air for what seemed like an impossibly long time before drifting to the ground almost reluctantly. Little figures black against the snow and the fire came tottering or running from it, and witches flew down to help drag them away from the flames. Within a minute of the zeppelin's hitting the ground it was a mass of twisted metal, a pall of smoke, and a few scraps of fluttering fire.

But the soldiers on board, and the others too (though Lyra was too far away by now to spot Mrs. Coulter, she knew she was there), wasted no time. With the help of the witches they dragged the machine gun out and set it up, and began to fight in earnest on the ground.
