He looked up, and the witches followed his eyes. The stars in this world were the same as theirs: the Milky Way blazed bright across the dome of the sky, and innumerable points of starlight dusted the dark, almost matching the moon for brightness….
«Sir,» said Serafina, «did you ever hear of Dust?»
«Dust? I guess you mean it in some other sense than the dust on the roads. No, I never did. But look! There's a troop of angels now….»
He pointed to the constellation of Ophiuchus. And sure enough, something was moving through it, a tiny cluster of lighted beings. And they didn't drift; they moved with the purposeful flight of geese or swans.
Ruta Skadi stood up.
«Sister, it's time I parted from you,» she said to Serafina. «I'm going up to speak to these angels, whatever they may be. If they're going to Lord Asriel, I'll go with them. If not, I'll search on by myself. Thank you for your company, and go well.»
They kissed, and Ruta Skadi took her cloud-pine branch and sprang into the air. Her daemon, Sergi, a bluethroat, sped out of the dark alongside her.
«We're going high?» he said.
«As high as those lighted fliers in Ophiuchus. They're going swiftly, Sergi. Let's catch them!»
And she and her daemon raced upward, flying quicker than sparks from a fire, the air rushing through the twigs on her branch and making her black hair stream out behind. She didn't look back at the little fire in the wide darkness, at the sleeping children and her witch companions. That part of her journey was over, and, besides, those glowing creatures ahead of her were no larger yet, and unless she kept her eye on them they were easily lost against the great expanse of starlight.
So she flew on, never losing sight of the angels, and gradually as she came closer they took on a clearer shape.
They shone not as if they were burning but as if, wherever they were and however dark the night, sunlight was shining on them. They were like humans, but winged, and much taller; and, as they were naked, the witch could see that three of them were male, two female. Their wings sprang from their shoulder blades, and their backs and chests were deeply muscled. Ruta Skadi stayed behind them for some way, watching, measuring their strength in case she should need to fight them. They weren't armed, but on the other hand they were flying easily within their power, and might even outstrip her if it came to a chase.
Making her bow ready, just in case, she sped forward and flew alongside them, calling: «Angels! Halt and listen to me! I am the witch Ruta Skadi, and I want to talk to you!»
They turned. Their great wings beat inward, slowing them, and their bodies swung downward till they were standing upright in the air, holding their position by the beating of their wings. They surrounded her, five huge forms glowing in the dark air, lit by an invisible sun.
She looked around, sitting on her pine branch proud and unafraid, though her heart was beating with the strangeness of it, and her daemon fluttered to sit close to the warmth of her body.
Each angel-being was distinctly an individual, and yet they had more in common with one another than with any human she had seen. What they shared was a shimmering, darting play of intelligence and feeling that seemed to sweep over them all simultaneously. They were naked, but she felt naked in front of their glance, it was so piercing and went so deep.
Still, she was unashamed of what she was, and she returned their gaze with head held high.
«So you are angels,» she said, «or Watchers, or bene elim. Where are you going?»
«We are following a call,» said one.
She was not sure which one had spoken. It might have been any or all of them at once.
«Whose call?» she said.
«A man's.»
«Lord Asriel's?»
«It may be.»
«Why are you following his call?»
«Because we are willing to,» came the reply.
«Then wherever he is, you can guide me to him as well,» she ordered them.
Ruta Skadi was four hundred and sixteen years old, with all the pride and knowledge of an adult witch queen. She was wiser by far than any short-lived human, but she had not the slightest idea of how like a child she seemed beside these ancient beings. Nor did she know how far their awareness spread out beyond her like filamentary tentacles to the remotest corners of universes she had never dreamed of; nor that she saw them as human-formed only because her eyes expected to. If she were to perceive their true form, they would seem more like architecture than organism, like huge structures composed of intelligence and feeling.
But they expected nothing else: she was very young.
At once they beat their wings and surged forward, and she darted with them, surfing on the turbulence their pinions caused in the air and relishing the speed and power it added to her flight.
They flew throughout the night. The stars wheeled around them, and faded and vanished as the dawn seeped up from the east. The world burst into brilliance as the sun's rim appeared, and then they were flying through blue sky and clear air, fresh and sweet and moist.
In the daylight the angels were less visible, though to any eye their strangeness was clear. The light Ruta Skadi saw them by was still not that of the sun now climbing the sky, but some other light from somewhere else.
Tirelessly they flew on and on, and tirelessly she kept pace. She felt a fierce joy possessing her, that she could command these immortal presences. And she rejoiced in her blood and flesh, in the rough pine bark she felt next to her skin, in the beat of her heart and the life of all her senses, and in the hunger she was feeling now, and in the presence of her sweet-voiced bluethroat daemon, and in the earth below her and the lives of every creature, plant and animal both; and she delighted in being of the same substance as them, and in knowing that when she died her flesh would nourish other lives as they had nourished her. And she rejoiced, too, that she was going to see Lord Asriel again.
Another night came, and still the angels flew on. And at some point the quality of the air changed, not for the worse or the better, but changed nonetheless, and Ruta Skadi knew that they'd passed out of that world and into another. How it had happened she couldn't guess.
«Angels!» she called as she sensed the change. «How have we left the world I found you in? Where was the boundary?»
«There are invisible places in the air,» came the answer. «Gateways into other worlds. We can see them, but you cannot.»
Ruta Skadi couldn't see the invisible gateway, but she didn't need to: witches could navigate better than birds. As soon as the angel spoke, she fixed her attention on three jagged peaks below her and memorized their configuration exactly. Now she could find it again, if she needed to, despite what the angels might think.
They flew on farther, and presently she heard an angel voice: «Lord Asriel is in this world, and there is the fortress he's building….»
They had slowed, and were circling like eagles in the middle airs. Ruta Skadi looked where one angel was pointing. The first faint glimmer of light was tinting the east, though all the stars above shone as brilliantly as ever against the profound velvet black of the high heavens. And on the very rim of the world, where the light was increasing moment by moment, a great mountain range reared its peaks — jagged spears of black rock, mighty broken slabs, and sawtooth ridges piled in confusion like the wreckage of a universal catastrophe. But on the highest point, which as she looked was touched by the first rays of the morning sun and outlined in brilliance, stood a regular structure: a huge fortress whose battlements were formed of single slabs of basalt half a hill in height, and whose extent was to be measured in flying time.
