"Will," she said, "eat these leaves before you have any other food."

She gave him a handful of soft bitter-tasting leaves somewhat like sage, and he chewed them silently and forced them down. They were astringent, but he felt more awake and less cold, and the better for it.

They ate the roasted birds, seasoning them with lemon juice, and then another witch brought some blueberries she'd found below the scree, and then the witches gathered around the fire. They talked quietly; some of them had flown high up to spy, and one had seen a balloon over the sea. Lyra sat up at once.

"Mr. Scoresby's balloon?" she said.

"There were two men in it, but it was too far away to see who they were. A storm was gathering behind them."

Lyra clapped her hands. "If Mr. Scoresby's coming," she said, "we'll be able to fly, Will! Oh, I hope it's him! I never said good-bye to him, and he was so kind. I wish I could see him again, I really do…"

The witch Juta Kamainen was listening, with her red-breasted robin daemon bright-eyed on her shoulder, because the mention of Lee Scoresby had reminded her of the quest he'd set out on. She was the witch who had loved Stanislaus Grumman and whose love he'd turned down, the witch Serafina Pekkala had brought into this world to prevent her from killing him in their own.

Serafina might have noticed, but something else happened: she held up her hand and lifted her head, as did all the other witches. Will and Lyra could hear very faintly to the north the cry of some night bird. But it wasn't a bird; the witches knew it at once for a daemon. Serafina Pekkala stood up, gazing intently into the sky.

"I think it's Ruta Skadi," she said.

They kept still, tilting their heads to the wide silence, straining to hear.

And then came another cry, closer already, and then a third; and at that, all the witches seized their branches and leaped into the air. All but two, that is, who stood close by, arrows at their bowstrings, guarding Will and Lyra.

Somewhere in the dark above, a fight was taking place. And only seconds later, it seemed, they could hear the rush of flight, the whiz of arrows, and the grunt and scream of voices raised in pain or anger or command.

And then with a thud so sudden they had no time to jump, a creature fell from the sky at their feet—a beast of leathery skin and matted fur that Lyra recognized as a cliff-ghast, or something similar.

It was broken by the fall, and an arrow protruded from its side, but still it lurched up and lunged with a flopping malice at Lyra. The witches couldn't shoot, because she was in their line of fire, but Will was there first; and with the knife he slashed backhand, and the creature's head came off and rolled over once or twice. The air left its lungs with a gurgling sigh, and it fell dead.

They turned their eyes upward again, for the fight was coming lower, and the firelight glaring up showed a swift-rushing swirl of black silk, pale limbs, green pine needles, gray-brown scabby leather. How the witches could keep their balance in the sudden turns and halts and forward darts, let alone aim and shoot, was beyond Will's understanding.

Another cliff-ghast and then a third fell in the stream or on the rocks nearby, stark dead; and then the rest fled, skirling and cluttering into the dark toward the north.

A few moments later Serafina Pekkala landed with her own witches and with another: a beautiful witch, fierce-eyed and black-haired, whose cheeks were flushed with anger and excitement.

The new witch saw the headless cliff-ghast and spat.

"Not from our world," she said, "nor from this. Filthy abominations. There are thousands of them, breeding like flies… Who is this? Is this the child Lyra? And who is the boy?"

Lyra returned her gaze stolidly, though she felt a quickening of her heart, for Ruta Skadi lived so brilliantly in her nerves that she set up a responding thrill in the nerves of anyone close by.

Then the witch turned to Will, and he felt the same tingle of intensity, but like Lyra he controlled his expression. He still had the knife in his hand, and she saw what he'd done with it and smiled. He thrust it into the earth to clean it of the foul thing's blood and then rinsed it in the stream.

Ruta Skadi was saying, "Serafina Pekkala, I am learning so much; all the old things are changing, or dying, or empty. I'm hungry…"

She ate like an animal, tearing at the remains of the roasted birds and cramming handfuls of bread into her mouth, washing it down with deep gulps from the stream. While she ate, some of the witches carried the dead cliff-ghast away, rebuilt the fire, and then set up a watch.

The rest came to sit near Ruta Skadi to hear what she could tell them. She told what had happened when she flew up to meet the angels, and then of her journey to Lord Asriel's fortress.

"Sisters, it is the greatest castle you can imagine: ramparts of basalt, rearing to the skies, with wide roads coming from every direction, and on them cargoes of gunpowder, of food, of armor plate. How has he done this? I think he must have been preparing this for a long time, for eons. He was preparing this before we were born, sisters, even though he is so much younger… But how can that be? I don't know. I can't understand. I think he commands time, he makes it run fast or slow according to his will."

"And coming to this fortress are warriors of every kind, from every world. Men and women, yes, and fighting spirits, too, and armed creatures such as I had never seen—lizards and apes, great birds with poison spurs, creatures too outlandish to have a name I could guess at. And other worlds have witches, sisters; did you know that? I spoke to witches from a world like ours, but profoundly different, for those witches live no longer than our short-lifes, and there are men among them, too, men-witches who fly as we do…"

Her tale was causing the witches of Serafina Pekkala's clan to listen with awe and fear and disbelief. But Serafina believed her, and urged her on.

"Did you see Lord Asriel, Ruta Skadi? Did you find your way to him?"

"Yes, I did, and it was not easy, because he lives at the center of so many circles of activity, and he directs them all. But I made myself invisible and found my way to his inmost chamber, when he was preparing to sleep."

Every witch there knew what had happened next, and neither Will nor Lyra dreamed of it. So Ruta Skadi had no need to tell, and she went on: "And then I asked him why he was bringing all these forces together, and if it was true what we'd heard about his challenge to the Authority, and he laughed."

"'Do they speak of it in Siberia, then?' he said, and I told him yes, and on Svalbard, and in every region of the north—our north; and I told him of our pact, and how I'd left our world to seek him and find out."

"And he invited us to join him, sisters. To join his army against the Authority. I wished with all my heart I could pledge us there and then. He showed me that to rebel was right and just, when you considered what the agents of the Authority did in His name… And I thought of the Bolvangar children, and the other terrible mutilations I have seen in our own south lands; and he told me of many more hideous cruelties dealt out in the Authority's name—of how they capture witches, in some worlds, and burn them alive, sisters. Yes, witches like ourselves…"

"He opened my eyes. He showed me things I had never seen, cruelties and horrors all committed in the name of the Authority, all designed to destroy the joys and the truthfulness of life."

"Oh, sisters, I longed to throw myself and my whole clan into the cause! But I knew I must consult you first, and then fly back to our world and talk to Leva Kasku and Reina Miti and the other witch queens."

"So I left his chamber invisibly and found my cloud-pine and flew away. But before I'd flown far, a great wind came up and hurled me high into the mountains, and I had to take refuge on a cliff-top. Knowing the sort of creatures who live on cliffs, I made myself invisible again, and in the darkness I heard voices."
