Hork reached for the arrow device. “All right. Then let’s see if we can see what lies there…” He set the pointer at its penultimate setting.

The stars fled from the crumbling starbow and back to their scattered homes around the sky.

Hork Waved toward one of the imagined poles, peering through the blocky Ur-human cloud devices and into space. To Dura, who remained close to Karen Macrae, he looked like a toy, a speck swimming against the Ur-humans’ vague immensities.

“Nothing here,” he called at last, sounding disappointed. “Just an anonymous patch of stars.”

“Then it must be at the other end of the chamber. The other pole. Come on.”

She waited for him to return. Then, hand in hand, they Waved in the Star’s direction of flight.

…And there was something at the pole of the sky: something set against the backdrop of stars, something huge — if diminished by distance — and precisely defined.

Karen Macrae was saying something. The rustling words sighed across the huge silences of the chamber.

Dura and Hork hurried back and pressed their faces close to the Colonist’s cloudy lips. “What is it?” Dura demanded, almost despairing. “Won’t you try again? What are you saying to us?”

…The Ring. Can you see it? I’ve so little processing power here… hard to… the Ring…

Dura turned away and looked at the artifact; and a fear borne of childhood tales, of old, distorted legends, welled up in her.

The car sailed away.

Adda hung on to the ward’s improvised doorframe and sucked Air into his lungs. He glanced around the sky. The panorama, now somber and deep yellow, grew less and less like the secure, orderly Mantlescape he’d grown old with: the vortex lines were discontinuous shreds of spin loops struggling to reform, and the starbreaker beams continued to cut down through the Air and into the Core, unnaturally vertical.

Tired as he was, something probed at the edge of his awareness. It seemed darker than before. Why should that be? He pushed himself out of the ward and Waved a few weary mansheights into the sky. Behind him, the Skin was a limitless wooden wall which cut away half of the sky. It was bounded about by the huge anchor-bands and punctuated by a hundred crude gashes; a slowing trickle of cars and people still dribbled from the opened-up walls and diffused into the wastes of the Air. The Skin was dark, intimidating…

Too dark. That was it.

Adda Waved a little further and twisted his head around, surveying the Corestuff anchor-bands. The huge hoops were like a gray cage over the City’s wooden face — but they were dull, lifeless, where a little earlier they had crackled with blue electron gas.

The glow of the gas had gone.

So the dynamos, the huge, wood-burning lungs of the City, had failed at last. Perhaps they had been abandoned by their attendants; or maybe some essential part of the City’s infrastructure had failed under the strain of holding the City against the fluctuating Magfield.

It scarcely mattered.

There was a sharp explosion. A hail of splinters fanned out from the base of the City, at the junction of the Spine and the main inhabited section. The splinters sailed away through the showers of sewage material still falling from the base of Parz.

There might be no more than heartbeats left.

Adda Waved strongly back to the improvised Hospital port and dived into the melee of swaddled patients, harassed staff and volunteers. He found Farr helping Deni Maxx to fix a patient’s bandages. He grabbed Farr’s and Deni’s arms roughly; he hauled them away from the unconscious patient and toward the exit.

“We’ve got to get out of here.”

Deni stared at him, the deep yellow Air-light scouring shadow-lines in her face. “What is it? I don’t understand.”

“The anchor-bands have lost power,” Adda hissed. “They can’t sustain the City, here above the Pole. The City’s going to drift — come under intense stress… We have to get away from here. The City will never withstand it…”

Farr glanced back to the patients and helpers. “But we’re not finished.”

“Farr,” Adda said with all the persuasiveness he could muster, “ it’s over. You’ve done a marvelous job, but there’s nothing more you can do. Once the effects of the band failure hit we won’t be able to complete the evacuation anyway.”

Deni Maxx stared into his face, her mouth tight. “I’m not leaving.”

Adda felt his scarred old heart break once more.

“But you’ll die,” he said, hearing a plea in his voice. “These wretched people can never survive anyway. There’s no point…”

She pulled her arm from his grasp. She looked back into the ward, as if all this had been a mere distraction from her work.

When he placed his hand on the crude doorframe he felt a deep, shuddering vibration, coming from the very bones of the City, and shivers of turbulence crept across the bare skin of his arms and neck.

Maybe it was already too late. He pulled himself through the improvised doorway and into the open Air.

He looked back into the ward. Deni Maxx was making her way back into the chaos of patients and helpers, her face set. Already she’d dismissed his warning. Forgotten it, probably. But Farr still lingered close to the doorway; he looked back into the ward, apparently torn.

Well, Deni was lost; but not Farr. Not yet.

Adda grabbed Farr by the hair and, with all his remaining strength, hauled the boy backward out of the Hospital and hurled him into the Air. Farr came to rest in the empty Air, struggling; he looked like some stranded insect, dwarfed by the immense, wounded face of the City. He glared at Adda. “You had no right to do that.”

“I know. I know. You’ll just have to hate me, Farr. Now Wave, damn you; Wave as hard as you’ve ever Waved in your life!”

There was a glow from the North, a deep, ominous red glow from all around the sky. It was a light Adda had never seen before. It soaked the Mantle in a darkness in which the starbreakers of the Xeelee glowed like opened-up logs.

Another shout of tearing wood and failing Corestuff was wrenched from the guts of the City. The Skin rippled; waves perhaps a micron high spread over its surface, and the wood broke open in tiny explosions.

Adda dropped his head and kicked at the seething Air, Waving away from Parz as hard as he could.

The Ring was reduced by distance to a sparkling jewel, lovely and fragile.

“I believed most of it,” Dura said slowly, “most of the stories my father told me… But I don’t think I ever quite believed in the Ring itself.”

Bolder’s Ring, the greatest engineering construct in the universe. So massive — rotating so rapidly — that it had ripped a hole in space itself.

“The Ring is a doorway in the universe, a way for the Xeelee to escape their unknown foe,” she told Hork.

His fists clenched; dwarfed by the huge sky around him, his belligerence looked absurd. “I know your legends. But what foe?” He crowded close to Karen Macrae and drove his fist into the cloud of jostling cubes which comprised her face. His hand passed through, apparently unaffected. “What foe, damn you?”

Slowly Karen Macrae began to talk, the globes in her eyecups glinting. She spoke hesitantly, in fragments.

The Star was spawned in a galaxy, a disc of a hundred billion stars. It was actually ancient, the cooling remnant of an immense explosion which had driven away much of a massive star’s bulk and devastated the gray companion which still accompanied it. As time wore on the Star had drawn material from the companion, knitted gas into planets.
