It was hard to tell the man's age; his face was lined and weatherbeaten, his brow sunburnt and his eyes narrowed to a perpetual squint. But he was fit and strong-looking, and Livia had no doubt he could throw that spear with great accuracy and force.

But he hadn't spotted them. He was staring up into the trees with a puzzled expression on his face. Livia took the opportunity to start backing away.

"What is he?" she whispered,

"Not an Impossible," said Lucius. "More likely a warrior of Raven. Their manifold overlaps ours in most places. They can visit us, but they rarely do."

Livia had known that for years, of course, but somehow, despite her experience with manifolds, seeing this man was a shock. She thought of invisible warriors ranging through the Romanal gardens, firing arrows at deer on the tennis courts.

"Aren't we ... well, sort of at war with Raven?"

Lucius shook his head. "Only in the gamers' submani-fold. It's purely voluntary — " He froze, because the man had spotted them.

For a while neither he nor they moved a muscle. Livia's heart was pounding, but her mind was clear. What was he doing here? Had he stepped out of Raven's people into Westerhaven? Or had she and Lucius strayed the other way?

Finally the man snapped out of his trance. Carefully, he leaned his spear against a tree, then walked toward them. Stopping four meters away, he cleared his throat

"You have come to celebrate with us," he said.

"Yes," replied Lucius.

"What?" said Livia.

The warrior strode forward, extending his hand. "I am King Ghee," he said. "Do not be afraid, I was sent to find you. I am ... you would call me a diplomat, I believe." He smiled at Livia, showing white, perfect teeth.

"I am Lucius Xavier, and this is my friend, Livia Ko-daly," said Lucius. "So we are not too late?" Lucius seemed anxious.

King Ghee glanced up at the sky. "No. But we must hurry." The warrior set off up the path, snatching up his spear on the way.

"Lucius? What's going on?" Livia tried to keep her voice controlled, with some success, but anger and fear made her hesitate as the other two walked ahead.

"Come, Livia." Lucius waved to her. "This is important. You'll see why."

"But why didn't you tell me that you were meeting someone?" She verified that her angels were still around her, then reluctantly stepped after him. He had not replied.

"I am pleased to meet you," Raven's warrior said to her as she caught up. "You must be highly prized by your own people to be given this opportunity." Livia opened her mouth to ask him what he meant by mat, then noticed Lucius making a warning gesture behind him. She smiled.

"Thank you," she said. "I am honored, yes." She needed to know what was happening, so she summoned an anima to replace her in this dialog, intending to split off and ask Lucius just what he was playing at But in-scape signaled an error: this warrior of Raven could not perceive animas. They walked now, it seemed, on the very edge of Westerhaven.

"So you will come with me to the city of Skaalitch?" asked the warrior. "It is not far, but it is under Raven's wing; your people would not normally see it."

Lucius grinned. "I'd be honored, Kingy." He said the name as if it were one word. Livia did still have access to her internal inscape systems, so she called up a database of Raven names. Qiingi — that was it. And Skaalitchi The database had a listing, but she had no time to examine it as the warrior spoke again.

"To come to us, you must open yourself to the sacred-ness of living things. Walk with me, under Raven's wing." He stepped off the path.

"So the real adventure begins," said Lucius. "Sorry I kept you in the dark, but you might not have come otherwise. Well, Liv? Are you up for it?"

She opened her mouth to chastise him, but somehow his enthusiasm was infectious. And, she realized, she was enjoying her surprise. "All right," she said with a laugh. "But there had better not be any more tricks. I need to be back by lunchtime."

Qiingi wavered in and out of existence ahead of them. He often paused, instructing Livia and Lucius in what they should look for. Livia tried to forget about Westerhaven — her Societies' intrigues, the arcing aircars and glittering cities — and instead focus on spotting the creatures of the forest. With Qiingi, she paused to gaze at tracks on the damp ground, and consciously drew in the scents of pine and moss. It was a game she'd learned as a child, not knowing its significance at the time; only later, when her ability to shift manifolds was unlocked at puberty, did Livia understand. Now, she stopped, staring at an owl she'd spotted on a branch. She concentrated, frowning, and the bird suddenly changed, its face momentarily becoming a shaman's mask. Livia laughed out loud. Follow, follow the warrior of Raven, she told herself, as she dashed after him. As she went, the bark of the trees shifted from randomness to patterned design. The birdsong ceased to be incoherent twitters, and became tiny, piping voices whose words she could understand if she concentrated.

So, by degrees of wonder, Livia left the world of West-erhaven behind, and came within the realm of Raven.

"They are heralds of the ancestors," Qiingi said. Livia had asked him about the Impossibles. "The ancestors are returning to us, so all things change. You should not be surprised if the walls of your world are beginning to crumble. The elders told us to expect it."

"Who are these ancestors?" she asked. She really wanted to grill Lucius about what he was up to, but the man kept cagily near Qiingi, and as they crossed the border into Raven's country, her normal inscape resources had shut down. She couldn't call upon Peaseblossom and Cicada to run sims of Lucius, nor could she ask her Society what he might be doing.

The term for this, she mused, was working without a safety net. Most of her peers prized the stability of their reality above all else, and she had no doubt they would have run screaming back to Westerhaven long before now. In that, at least, Lucius had judged right: Livia was unfazed by this journey. Or so she kept telling herself, while her pulse pounded and she jumped at every strange sound coming through the forest.

Qiingi smiled at her; he had been very impressed to learn she was a singer. He had taken to calling her Word-weaver Kodaly. "A time is coming when what you call the horizons of the world crack and fall," he said. "The ancestors wait beyond the horizons. They are returning to us to bring us the wisdom of centuries that they have gathered during our long isolation in this place. Our best have come to Skaalitch because this is the first place where the walls of the world will crack."

"Oh." She didn't know what to say to that. But it sounded tike some new myth was being born in this place. Myths and stories were a common spark for birthing new manifolds. Was a new reality being born within Raven's people? Was that what Lucius had brought her to witness? If so, it was a momentous occasion, and a tremendous coup for both of them.

"You have followed me well," Qiingi said. "Behold the city of Skaalitch."

Livia knew where they were. They had come to the shoreline of the lake that spread sinuously through the valley below the Romanal estate. The air here was cold and damp, full of the mist that hung around the redwoods. Livia drank in the sound of waves lapping on the shore of the dark water. She had been here many times; the Romanal boathouse should be right over ... there ... Where the boathouse should be, a jagged mound of boulders thrust up out of the ground.

Of course, that was the boathouse — or how it appeared from within Raven's country. She looked the other way, and gasped.

The lake was ringed by gigantic trees and backed by low mountains. For hundreds of meters along the shore, long canoes lay upended on wooden frames and tall totem poles presided magisterially over scores of men and women who were working near the water. Behind them, receding half-seen into the maze of trees, were dozens of log longhouses, their roofs adrift with woodsmoke. Bright things like flying banners flitted half-seen in the deepening green of the forest; birds and animals laughed, and out in the lake, something huge and dark breached the surface momentarily, then sank away.
