Qiingi let out a deep sigh. He looked stricken, in a way he had not during all their adventures on the way to this place. "Qiingi, what is it?"

"I approached him," he said. "I wasn't sure, because his appearance was very different when he was with us." He met her eyes sadly. "That, Livia Kodaly, is my founder. Raven."

"There's nowhere to go," the old man was saying. "These invaders are spreading everywhere. They're close to shutting down the tech locks. Then they won't need to skulk around anymore." He didn't talk like Qiingi, Livia realized; this Raven sounded more Westethaven than anything. But she didn't comment on that to Qiingi.

"Somewhere, someone must have a manifold that can resist this '3340,'" said another of the debaters. This was Francis Munari, the best military thinker among the peers; he had apparently arrived here with the remains of the Barrastea rearguard several days before.

Several others took up the thread of his argument. Raven kept shaking his head, but he was drowned out for the moment. With a groan, Livia levered herself to her feet and walked over to the circle.

"It's not a technical problem," she said, projecting her authority as best she could. Heads turned.

"That's why nobody's able to resist them," she continued. "What nobody seems to get is that the manifolds use inscape and the locks, but they're not created by them. They're created by ideals."

"Make sense, Livia!" snapped Francis. "While you talk, they're digging through the ice to get us. Make sense or give the floor to somebody else."

Raven bowed to her. He had a charming face, a bit satyrlike with a fringe of white hair around his bald scalp. "Livia Kodaly, it's an honor. You've seen what I've seen, haven't you? That the ancestors aren't attacking us through our technology?"

"Yes. That's the problem." Reluctantly, she walked into the circle. "The tech locks seem untouched; if they weren't this form of attack wouldn't be necessary. The invaders have a little control over inscape, just enough to be able to distort messages and meanings. But they can't seem to attack the locks directly. They're probing each manifold to find out what its highest ideal is, then they come and promise a new way to get to that ideal. It's different for each manifold, but the end result is that people hand control over to them."

Francis crossed his arms. "How do you know this?"

"When we set out to find this place, there were sixteen of us," she said. "We ran from manifold to manifold — each time thinking we'd shaken our pursuers. And each and every time, we found they'd gotten there before us. As if they had always been mere, hiding in the cracks of the world." Trying to escape pursuit, Livia had led her people through the warrens of a vast, baroque stone city that clung nice lichen to the ascending cable, isolate and paranoid. From there they had slipped past cloud cities and arbors that hung in the sky like a dream of angels, and past hardscrabble farms perched on sagging square-kilometer nets of sailcloth that hung in the permanent mist When they ran out of sky, they walked a length of frayed cable down to the mountaintops and hid in the mazes of a forest-dwelling people who seemed more owl than human. In every place she met some manifestation of 3340; and in each one she lost one or two people.

"I know it was 3340, once or twice," she said. "Catching the stragglers as they tried to open their hearts to a new destination. But more often, it was just too hard for our people to go on. To reject the values of the place where we were resting for a day or two — to embrace new values in order to see a different world." Each new place was a revelation of sorts: an example of a new way to live. A couple of the refugees had found paradise during that long climb, and simply refused to leave it A couple had found hell.

"Everywhere we went, we tried to warn the people," she continued. "No one believed us. In many places, we couldn't even find the words to explain what's happening — if you tried you would start to fade." She shook her head sadly. "I never knew how many manifolds had turned in on themselves. Even though we all went through the freeing of inscape that happens at puberty, most people no longer seem to believe in any reality beyond theirs."

She ran out of steam. For a while there was silence. Then Raven cleared his throat.

"Some of you are wondering how I came to be here with you." He glanced significantly at Qiingi. "I did not betray my people. But the animals — my spirits — they deceived me. I didn't know about the presence of the ancestors until it was too late. Then for a while I lived as a 'guest' of these invaders."

He looked down at the stone floor. "I only escaped after the Oceanus incident."

"How is it you escaped?" someone asked suspiciously. "It seems a bit convenient. How do we know you're not working with them?"

Raven looked back at the man blandly. "You don't. I escaped because I had help from one of your founders — Maren Ellis. She trusted me, and some of you here trusted me enough to take me in. For that I'm grateful." He raised his voice. "I've seen what these ancestors are doing to our people. They're trying to shut down the tech locks. Men and women of Raven who spent their whole lives learning to work leather, or carve wood, now can get clothing or shelter with a simple gesture. Their life's work is rendered meaningless. And your diplomats and seekers of knowledge have nowhere to go now; all inscape's differences are being annihilated by the conquerors."

"But why?" asked Francis. "If we're going to fight them, we need to know why they're doing this."

Raven hesitated. "I don't know," he said at last. "They don't need human labor. They grow machines for that. They aren't plundering our treasures — they ignore them. And they're not telling us what to do, they don't seem to need that kind of power over people. But they're changing us. Changing the people themselves."

"What do you mean?" asked Francis. A hush had fallen over the crowd.

"We lived in a world that accommodated the human need for meaning," said Raven. "It let us know that our beliefs were valuable in and of themselves. The invaders reject that; they say that our beliefs are only valuable insofar as they serve something else. Something they call 3340 and will not define any more clearly.

"But they are clear about one thing. Those who follow 3340 will gain the power of gods. All we have to do to achieve this power is abandon the realities we've been building all our lives."

The stone floor shook under Livia. "They're into the corridors!" someone shouted. With that signal, the crowd melted away as humans, angels, and agents all raced to their posts. Qiingi was offered a weapon and accepted it gratefully. Francis shouted orders; massive engines stood up on their hydraulic legs and began stalking after him toward the stairs. In seconds Livia found herself standing with Raven and a few of the refugees. Aaron was awake, and now stood unsteadily, holding his head.

Livia watched the action with a resigned sense of detachment. "Such a lot of effort," she heard herself saying, "for a day or two's reprieve."

Aaron scowled at her. "What else are we supposed to do? If you're right, there's nowhere to run to."

She shook her head. "I never said that" She turned to Raven. "There is an alternative, isn't there? You knew this attack was coming."

Raven shrugged. "We didn't know. We ... saw some signs. We were worried that we'd gone too far in our isolationism. So we decided to take steps."

"In secret?"

"The other founders would never have agreed to it."

Aaron looked from Livia to Raven. All three of them turned to look past the chaos of running people, to where Aaron's experimental barrels sat in a far corner.
