They slowed, as if now he was not their prisoner but their leader, and Gildas strode breathlessly up and said, "Your brother hasn't shown himself"

"He'll turn up." Saying it helped.

They walked swiftly, closed into a tight group. On either side the ground was seamed with pits and traps; Finn saw the steel teeth gleam in their depths. Glancing back, he was surprised at how the City was already far behind, its walls lined with people, watching, shouting, holding their children up to see.

The guard captain said, "We turn off the road here. Be careful; step only where we step and don't think of running off. The ground is sewn with fireglobes."

Finn had no idea what fireglobes were, but Gildas frowned. "This Beast must be fearsome indeed."

The man glanced at him. "I have never seen it, Master, and don't intend to."

Once off the smooth road the going was rough. The coppery earth seemed to have been scored and clawed into vast furrows; in several places it was burned, carbonized to a charcoal crispness that rose in clouds of dust as they trod on it, or vitrified almost to glass. Enormous heat would have been needed to do that, Finn thought. It stank too, an acrid cindery smell. He followed the men closely, watching their steps with nervous attention; when they paused and he raised his head, he saw that they were far out on the plain, the Prison lights so high above they were brilliant suns, casting his and Gildas's shadows behind them.

Far in the mile-high vault the bird still circled. Once it screeched, and the guards looked up at it. The nearest muttered, "Looking for carrion."

Finn began to wonder how far they would walk. There were no hills out here, no ridges, so where would they find a cave? He had pictured it as some dark aperture in a metallic cliff.

Now he was filled with a new apprehension, because even his imagination was betraying him.

"Stop." The guard captain held up a hand. "This is it."

There was nothing there. That was Finn's first idea. Relief flooded him. It was all a pretense. They'd let him go now, run back to the City, spin some gruesome tale about a monster to keep the people quiet.

Then, as he pushed past the men, he saw the pit in the ground.

And the Cave.

JARED SAID, "You promised them maps that don't exist! It was a crazy idea, Claudia.

Things are getting so dangerous for us!"

She knew he was deeply worried. She crossed to his side of the carriage and said, "Master, I know. But the stakes are so high."

He looked up and she saw the pain was back behind his eyes. "Claudia, tell me you're not thinking seriously about this folly of Evian's. We are not murderers!"

"I'm not. If my plan works, there'll be no need of it." But she didn't say what she was thinking: that if the Queen really did find out, that if he, Jared, was in any danger at all, she would have them all killed without hesitation, even her father, to save him.

Maybe he knew it. As the carriage jolted he glanced out of the window and his expression darkened, his black hair brushing the collar of the Sapient coat. "Here's our prison," he said bleakly.

And following his gaze she saw the pinnacles and glass towers of the Palace, the turrets and towers festooned with flags and bunting, heard that all the bells were ringing to welcome her, all the doves flapping, all the cannon were being fired in deep booming salute from every mile-high terrace that rose in splendor into the pure blue sky. 

"Take this, and this."

The guard captain thrust a small leather bag and a sword into Finn's hands. The bag seemed so light, it must be empty. "What's in it?" he asked nervously.

"You'll see." The man stepped back and glanced at Gildas. Then he said, "Why not flee, Master? Why waste your life?"

"My life is Sapphique's," Gildas snapped. "His fate is mine." The captain shook his head.

"Suit yourself. But no one else has ever come back." He jerked his head at the Cave entrance.

"There it is."

There was a moment of tense silence. The guards gripped their axes tightly; Finn knew that this was the moment they expected him to make some sort of break for freedom, now that he had a sword in his hand and his back to unknown terrors. How many of those brought as Tribute had screamed and fought in panic here?

Not him. He was Finn.

Reckless, he turned and looked down at the crack.

It was very thin, and utterly black. Its edges were burned and scorched, as if the metal of the Prison's structure had been superheated and melted countless times into grotesque twistings and taperings. As if whatever crawled out of these metal lips could melt steel like toffee.

He glanced at Gildas. "I'll go first." Before the Sapient could object, he turned and lowered himself into the slash of darkness, taking one last rapid look into the distance.

But the scarred plain was empty, the City a remote fortress.

He slithered his boots over the edge, found a foothold, squeezed his body in.

Once he was below ground level, the darkness closed over him. By feeling with hands and feet he realized that the crack was a horizontal space between tilted strata, and it sloped down into the ground. He had to spread-eagle himself to fir in it, inching forward over a dark slab-like surface littered with debris that seemed to be stones and smooth balls of melted steel that rolled painfully under him. His fingers groped in dust and a lump of rubble that crumbled away like bone. He dropped it hastily.

The roof was low; twice it grazed his back and he began to fear being stuck. As soon as the thought touched him with cold terror he stopped.

Sweating, he gulped a deep breath. "Where are you?"

"Right behind." Gildas sounded strained. His voice echoed; a small shower of dust fell from above into Finn's hair and eyes. A hand grabbed his boot. "Move on."

"Why?" He tried to roll his head to look back. "Why not wait here till Lightsout, then crawl back. Don't tell me those men will wait out there until dark. They've probably gone already.

What's to stop us ...?"

"Fireglobes are to stop us, fool boy. Acres of them. One wrong step and your foot's blown off. And you didn't see what I saw last night, how they patrol the City walls, how vast searchlights sweep the plain all night. We'd be easily seen." He laughed, a grim bark in the darkness. "I meant what I said to the blind women. You are a Starseer. If Sapphique came here, so must we. Though I fear my theory that the way out leads upward seems doomed to be proved wrong."

Finn shook his head in disbelief. Even in this mess the old man cared more about his theories than anything else. He scrabbled on, digging the toes of his boots in and heaving himself forward.

For the next few minutes he was sure that the roof was dipping so low that it would meet the floor and trap him; then, to his relief, the gap began to widen and at the same time tip leftward and slope more steeply. Finally he could rise to his knees without banging his head on the roof. "It opens ahead." His voice was hollow.

"Wait there."

Gildas fumbled. There was a loud crack and light hissed; one of the crude, smoking flares the Comitatus had used to signal distress. It showed Finn the Sapient lying flat on his stomach dragging a candle from the pack. He lit it from the flare; as the spitting red light died, the small flames flickered, guttering in a draft from somewhere ahead.
