His intention was to reach it so that he could warn the lady Fanning that they had company—but halfway across the open grassland he heard thuds behind him as half a dozen bodies hit the ground on his side of the wall. They were catching up, and quickly.

He flattened and rolled to one side. Grass swished as dark figures passed by, only feet away. Garth cursed under his breath, wishing there were some way to warn Venera Fanning that six heavily-armed men were about to pay her a visit.

Venera heard them coming. The darkness wasn't total—Diamandis had left a candle burning—so she wasn't completely disoriented when she awoke to voices saying, “Circle around the other side,” and “this must be his bolt-hole.” A flush of adrenalin brought her completely awake as she heard scratching and scuffling just outside the hovel's door.

She rolled out of bed, heedless of the pain, and ran to the table where she snatched up a knife. “Down here!” someone shouted.

Where were her clothes? Her jacket lay draped across a chair, and on the table were the bracelet and earrings Diamandis had left her. She cast about for her other things, but Diamandis had apparently moved them. There they were, on another table—next to the opening door.

Venera's first inclination would normally be to draw herself up to her full five foot seven and stare these men down when they entered. They were servants, after all, even if they were armed. If she could speak and make eye contact, Venera was completely confident in her ability to control members of the lower classes.

At least, she used to be. Recent events—particularly her unwelcome dalliance with captain Dentius of the winter pirates—had made her more cautious. In addition, she was sore all over and had a pounding headache.

So Venera snatched up the candle, her jacket, and the jewelry and knelt under the table. The rope ring scraped her raw skin as she yanked on it; after a few tugs the mysterious hatch lifted. She felt down with her foot, making contact with a metal step. As men blundered into Diamandis's home, she billowed the damp sheet behind her, with luck to drape over the hatch and hide it.

The candle guttered and nearly went out. Venera cupped a hand around it and cautiously felt for the next step. She counted seven before finding herself standing in an icy draft on metal flooring. A constant low roar made it hard to hear what was going on above.

This small chamber was oval, wider at the ceiling than at the floor, and ringed with windows. All the panes were flush with the wall, but a couple vibrated at a high speed, making a low braying sound. They seemed to be sucking air out of the room; it was the walls that soaked cold into the place.

Diamandis evidently used the room for storage because there were boxes piled everywhere. Venera was able to make her way among them to the far end, where a metal chair was bolted to the floor. The windows here were impressive: floor-to-ceiling, made of some resilient material she had never seen before.

The candlelight seemed to show a dense weave of leaves on the other side of the glass.

She was going to freeze unless she found something to wear. Venera ransacked the boxes, alternately cursing and puffing out her cheeks in wonder at the strange horde of broken clocks, worn-out shoes, rusted hinges, frayed quills, moldy sewing kits, left socks, and buckles. One crate contained nothing but the dust jackets of books, all their pages having been systematically ripped out. It was a small library's worth of intriguing but useless titles. Another was full of decaying military apparel, including holsters and scabbards, all of it bearing the same coat of arms.

At least the activity was keeping her warm, she reasoned. The faint clomp of boots above continued, so she moved on to a new stack of boxes. This time she was rewarded when she found it packed with clothing. After dumping most of that onto the floor she discovered a pair of stiff leather pants, too small for Diamandis but sufficient for her. Getting into them wasn't easy, though—the material scoured her already-raw skin so that it hurt to move. The leather cut out the wind, however.

Once she had done up the flight jacket, Venera sat down in the metal chair to wait for whatever happened next. This was much harder; it wasn't in Venera's nature to remain still. Staying still made you think, and thinking led to feeling, which was seldom good.

She drew her knees up and wrapped her arms around her shins. It came to her that if they took away Diamandis and she couldn't get out of here, she would die and no one would ever know what had happened to her. Few would care, either, and some would rejoice. Venera knew she wasn't well liked.

More stomping up above. She shivered. How far away was her home in Slipstream? Three thousand miles? Four? An ocean of air separated her from her husband, and in that ocean gyred the nations of enemies, rising, lowering, drifting with the unpredictable airs of Virga. Awaiting her out there were the freezing abysses of winter, full of feathered sharks and pirates. Before the sun of suns had roasted her into unconsciousness, she had been determined and sure of her own ability to cross those daunting distances alone. She had leaped from the cargo nets of Hayden Griffin's jet and soared for a time like a solitary eagle in the skies of Virga. But the sun had caught up to her and now she was here, trapped and in pain hardly any distance from where she'd started.

She climbed off the chair, fighting a wave of nausea. Better to surrender herself to whoever waited above than die here alone, she thought—and she almost ran up the steps and surrendered. It was a pulse of pain through her jaw that stopped her. Venera drew her fingertips across the scar that adorned her chin, and then she backed away from the steps.

Her heel caught the edge of a box she'd dropped, and she stumbled back against the icy windows. Cursing, she straightened up, but as she did she noticed a gleam of light welling up through the glass. She put her cheek to it—which dampened the pain a bit—and squinted.

The windows were covered with a long-leafed form of ivy. The stuff was vibrating with uncanny speed—so quickly that the leaves’ edges were blurred. Diamandis had said that Spyre rotated very fast; was she looking into the air outside?

Of course. This oval chamber stuck out of the bottom of the world. It was an aerodynamic blister on the outside of the rotating cylinder, and that chair might have once fronted the controls of a heavy machine gun or artillery piece mounted outside. It still might. Frowning, Venera clambered over the mounds of junk back to the metal seat and examined it.

There was indeed a set of handles and levers below the chair, and more between the windows. She didn't touch them but peered out through the glass there, as light continued to well through the close-set leaves.

Candesce was waking up. The sun of suns lit a zone hundreds of miles in diameter here at the center of Virga. Past the trembling leaves, Venera could see a carousel of mauve and peach-painted cloud tumbling past with disorienting speed; but she could also see more.

The oval blister was mounted into a ceiling of riveted metal, as she'd expected. That ceiling was the hull of Spyre. Covering this surface in long runnels and triangles was the strange ivy. Its leaves were like knives, sharp and long, and they all aligned in the flow of the wind. Venera had heard of something called “speed ivy"; maybe that's what this was.

The ivy seemed to prefer growing on things that projected into the airstream. Sheets of metal skin were missing here and there—in fact, there were outright holes everywhere—and the ivy clustered on the leading and trailing edges of these, smoothing the airflow in those places. Maybe that was what it was for.
