Still the girl smiled, padding relentlessly on. They were all but carrying Maruha by then. When they heard gargling and barking in the passageway behind, accompanied now by a deeper, inhuman grunting and snuffling, Brandl's eyes widened.

"Is it… ?" He glanced at Collum, who nodded grimly.

"Aye, lad. Trolls. No eyes and twice again our size—they hunt by scent alone."

Maruha managed to raise her bowed head from her breast. "We must find an exit soon, or we're all done for," she whispered. "Blind trolls won't shun the pale girl's light."

But for the moment, they could only bolt deeper into the unknown tunnel. The narrow side passage wormed through the stone without intersection. Cursing between their teeth, the duaroughs had soon outstripped the girl, whose pace never quickened, never slackened. Now they worked desperately at the metal portal overhead, its surface overgrown with hard lime and stone daggers. It was the first exit they had found—was, in fact, their only chance of escape, for the corridor ended a half dozen paces beyond.

"Perish the lime," Collum grated. "Wherever this leads, it hasn't been used in years."

A great mass of stone daggers peeled from the aperture's rim under the onslaught of his pick and shattered on the floor. Behind him, Maruha groaned and wiped her brow with her sleeve. She reclined to one side, breathing shallowly, her wounded arm cradled to her breast. The flesh of her wrist was puffed and red, her face flushed.

"Just as well," she answered hoarsely, "or likely they'd have sealed it properly."

She cast an exhausted, harried glance back down the corridor. The sound of shrill, whistled baying and low, throaty whuffling was louder now. Brandl struck off another dagger, and Maruha weakly tugged the upperlander back as it, too, broke upon the floor, throwing fragments that rattled against the walls.

"There," Collum said at last. "Let us see if it will turn."

Teeth gritted, he handed his tool to Brandl and grappled with the hub. A little of the stone still encrusting it crumbled, but the cover itself did not budge.

"Odds and blast," he muttered.

Brandl gave Maruha both picks and, gripping the other set of handholds, he added his strength to the older duarough's. They strained again. This time the metal groaned and gradually gave. Slowly, the cover rotated. It screwed out of the ceiling, shrieking, and fell open with a clang. A brief grin lit Collum's face.

Brandl laughed. Panting, the bearded duarough dusted his hands off on his breeches. The high-pitched baying down the corridor behind them echoed in the close confines of the tunnel. Approaching footsteps boomed. Collum and Brandl hastily pulled Maruha to her feet.

Silently, the girl moved past them and climbed upward through the hatch. As she emerged, she heard Brandl following. Collum quickly boosted Maruha through, then came himself. A moment later, he pulled the hatch to, and the sound of their pursuers was abruptly cut off. Collum screwed shut the round door and slid a bolt into place to prevent its being turned again from below. The pale girl stood away from the now-sealed opening, her smile broadening. The Call was much stronger here.

Gazing about her, she realized all at once that she stood upon the planet's surface, no longer underground. A vast City surrounded her, like none she had ever seen. Strange, stately buildings of colored glass rose on every side, flanking deserted streets. No carts or foot traffic thronged the broad thoroughfares. No lights shone. No sound came, not even an animal's cry. The City stood silent, dead.

Above her, the sky stretched black, as it always did, night or day. It was night now, for the blinding white jewel of Solstar hung nowhere above the horizon. Only starlight and the ghostly blue face of Oceanus peered down at her through the vast crystal Dome enclosing the City. No wind moved, and the air was thick, heady, hard to breathe. She had never tasted such air before: Ancients' ether.

"By the underreaches of the world," murmured Brandl, gazing about him at the dark, silent, shimmering buildings of colored glass. "No song or story ever told it was like this."

"I've never been aboveground before," whispered Maruha. "Is that the sky? Without the Dome overhead, I'd feel I might float away from the ground."

Collum shuddered and ducked his head. "Be glad we came up when it's night," he murmured. "If the light of Solstar fell on us, we'd turn to stone. Duaroughs weren't made to bear such light as that."

The pale girl wasn't listening. The Call was irresistible now. She started down the grand street that lay before her. Automatically, the others followed. With the danger of trolls and weaselhounds safely skirted, they too had fallen once more under the influence of the Call. Maruha walked slowly, leaning against Collum, exclaiming time and again over the machinery they passed.

"What was its function? Where did it come from? Who tended it?"

Brandl fingered his harp through the fabric of his pack. "Look at the arches on their doorways!" he whispered. "How tall they must have stood."

The girl paid no attention to anything they said. Turning down a very wide, straight street, she saw at the end of it a great building of green, violet, and indigo glass. A beacon burned in its spire, white and brilliant as Solstar. It was from there that the Call issued. She felt it. Relief and joy filled her. Eagerly, she hurried forward, almost running.

"Look," cried Brandl.

"It's the Ravenna's hall," Maruha said. "It must be."

"Aye, but is the Ravenna even there to be found?" muttered Collum. "Or just her body? The Ancients left bodies when they died, you know. They didn't fall to ash in a few hours' time, like normal folk. Sooth, what makes that light?" he exclaimed. "No oil I know burns so clean and clear."

The pale girl trotted on. The beacon reminded her of a burning crown, of a tower in which she had once stood, watching a great Flame flare… But the memory slipped away. She focused on the glass palace ahead. The nearer she came to it, the safer she felt. She hastened until she reached the hall: huge and broad based, it seemed to reach up to heaven itself.

A great door, blank as a mirror, stood at the top of wide steps, barring her. The girl halted and stared, astonished. She had expected no impediment. Her own image, dimly reflected in the dark portal's surface, stared back at her: fair and tall and slender still, but not starved or straggling. The sight of herself no longer frightened her.

But she had no time to study it now. She needed to enter the hall—and the door was in the way.

When she brushed it with one hand, it sang to her touch. It felt slippery, seeming to vibrate. Confounded, she recoiled from the strange sensation, then pounded the slick, shimmering door once, twice, angrily.

The reflections of the three duaroughs gaped at her from the glassy surface. Her fist against the barrier made a dull tonging sound. She scratched with her nails, and the hum sang musically, altering its tone each time she changed the way she struck it.

"Child, stop. Stop!" Maruha cried. "We've no idea what that is—"

Impatiently, the girl shook her off. Nothing mattered but her urgency to reach the source of the silent summons that drew her. She slapped the dark door with the flat of her hand. It tammered like a gong.

Brandl tried to take her other arm, but she snatched it from him. Her heel struck the humming surface, low. It boomed this time, a drum.

"She'll bring the wrath of the Ravenna down on us—" Collum started.

"So you do believe the Ancientlady may still live," panted Maruha with some satisfaction.

"Help me," Brandl exclaimed, trying to get hold of her again. "She's—"

He broke off abruptly. All four of them stopped, the three duaroughs falling back. Only the pale girl remained planted, staring as, upon the surface of the barrier, the head and shoulders of a man—much larger than life—suddenly shivered into being. His face was broad, with strong, high cheeks, his nose flattened and the nostrils flared. His skin was very dark, his tightly curled hair peppered with grey. He was wearing what might have been a tunic, black and silver. He seemed startled, disconcerted, and therefore fierce.

"Who knocks so at the port?" he demanded. "This City is closed."

His countenance alarmed the girl, but she glared back at the image, unable to answer. The three duaroughs came forward hesitantly.

"We… we seek the counsel of the Ravenna," Maruha began. "We have an upperlander who needs her aid."

The image of the man frowned and studied them. "Many need our aid," he answered presently, "but we cannot give it. Weightier matters occupy us. Do you not know of our instructions that no one is to disturb this City until we ourselves reopen it? How did you enter? The airlocks are barred."

"If by airlocks you mean gates leading to the desert outside—" Collum stammered. He looked terrified. "We did not come that way. We came by underpaths. We are duaroughs."

"I can see that," the dark man's image snapped.

"We thought all those gates sealed as well, and the service ports. I'm surprised the alarms didn't sound. No matter. By whatever path you entered, take yourselves off by the selfsame—"

"But we can't!" Brandl cried. "There are weaselhounds and trolls."

The other sighed in agitation. "Yes, of course. Oriencor's brood. I'd forgotten. Very well. I will open one of the airlocks for you and let you out into the desert."

"We'll turn to stone when Solstar rises!" Collum exclaimed.

"We'll starve," Brandl beside him said.

"Please, sir," Maruha begged. She was panting again, holding her injured arm, near the end of her strength. "We must see the Ravenna. This girl has the Witch's pin behind her ear—"

"That is not our concern!" the dark man's image answered sharply. "We cannot attend to you."

The pale girl growled. Desperate rage welled in her. She struck the man's image with the heel of her hand. The stone vibrated with a dull thrum, and the picture shimmered for a moment before reforming.
