Permanence

So they traveled on in their circuit of the giant failed star. All around, as they passed, the Lasa machinery that surrounded Apophis was changing. Over the next days Michael spent hours staring at the cloudscapes of the brown dwarf. Ancient and incredibly cold, they flowed like oil, a spectrum of icy blues visible only under extreme light amplification.

Apophis had been stillborn. It had never attained enough mass to burn hydrogen and so like all brown dwarfs it had glowed in its brief glory by gravity and magnetic forces alone. After billions of years, it had almost exhausted the heat of its birth. Only very rarely did the dwarf's magnetic field pull a twist of energy up through the atmosphere; then, wan arches of light would shimmer above the cloudscapes, only to flicker and collapse, exhausted, after a few minutes.

Nonetheless, bright things moved down in that realm, where flat, viscous thunderheads moved like charging armies across dark plains of dense cloud. Fusion-powered aircraft wove in and out among the starlit thunderheads, like birds at play. And in some places, great dark balloon cities drifted, tethers unreeling for hundreds of kilometers below them to tap the cloud decks. In the telescope, these balloons looked more like ancient battleships than craft of the air; to withstand eighteen gees of gravity, they were buttressed with squat girders and plated with titanium.

Were there windows in those floating fortresses? And did some entity, part of the mechanical ecology of Apophis, pause sometimes to gaze out at the stars?

Every now and then, sun-bright engines would kick into life atop one of those balloon cities. Stark nuclear light brought the gunmetal-blue cloudscapes into sharp relief, somehow making Apophis seem even colder and more alien. The tanker carrying lithium, beryllium and other hard-won treasures would climb laboriously for hours until it rendezvoused with a passing orbital tether.

The orbiting tethers grazed on whatever rose from the depths. They passed cargo packets up and past their orbital centers and flung them off their outermost arms. Each became a little world on its own, negotiating its position with the Twins through the music of gravity. After flying a million kilometers, each and every packet of cargo would arrive at a spot a few meters on a side, there to be caught by another tether in a higher orbit. This one would fling the cargo on its ultimate course, to meet with the invisibly distant construction shack that was the ultimate reason for all this activity.

Now, though, these intricate systems were falling silent. The jets cruised aimlessly. The floating cities withdrew their arms and hung silent. A few last cargo rockets clambered to the top of the atmosphere, but as they fell again they disintegrated in seconds. Stillness spread slowly, but unstoppably across the dark continents of air.

Michael's interceptor brushed the upper atmosphere of Apophis, briefly becoming a meteor before bouncing back into space. They shot silently through a province of motionless tethers and after another day lined up right behind the final cloud of packets heading for the shack. The cloud would act like chaff to the Banshee's radar; they would be invisible until they were almost to the shack.

There was really no preparing for what they might find there. They could only contemplate the world they had come to and, when they slept, let its dark kami whisper in their dreams.

RUE WAS EXERCISING to counteract free-fall weakness when the call came. The message, encrypted and sent by laser, was from the remains of their fleet, which was now spiraling toward the construction shack as unobtrusively as possible.

"Captain, we've got new reco

Images popped up, familiar at first: the twin balloons of the Banshee were now in full bolo configuration, swinging at opposite ends of a long tether. They appeared as twin glowing beads standing out from the long dark cylindrical body of the construction shack. Other photos showed close-ups of the habitats, which had been rounded can-shapes when Rue had ridden in the ship. One was still shaped that way; the other was smaller, spherical now, with a number of gathered bunches of fabric knotted at one end.

They had a catastrophic hull breach, Rue realized as she flipped through the rest of the images. Finally she came to one that showed the ramjet section of the starship. It was lit by six arc-welding torches. The tiny stars shone on long black scars and hairlike bunches of fullerene jutting out of the hull.

The scars were in lines, such as lasers would make. But where between here and the Envy could Crisler have gotten into a battle? It didn't make sense— unless Rue's crew had done something?

For a moment her heart leapt at the thought— but she knew the resources they'd had to work with. Unless they attacked the gu

Anxiously, she forwarded the images to the other vanguard interceptor. This ship, which contained Mike and Laurent Herat, was now almost directly behind the construction shack relative to her. They were approaching from opposite sides, according to plan and so far the Banshee didn't seem to have noticed. Indeed, the Banshee wasn't really sca

It took several seconds for round-trip messages and she didn't want to risk an open laser link, lest the beam overlap one of the Banshee's sensors. So Rue waited for long minutes while, she presumed, the others pored over the images. Finally Dr. Herat's face popped up in a little window.

"It looks like laser fire. The ship's badly damaged— I don't know if she'd be able to start the ramjet with the condition it's in. If Crisler's not expecting reinforcements, I'd say he's in pretty dire straits at this point. We may not need to fire a shot to take the Banshee."

This news should have cheered her, but Rue didn't like not knowing who had crippled Crisler's ship.

Her answer came six hours later, as she was eating. They had just completed a braking maneuver and were lining up for the final deceleration to rendezvous with the construction shack. Rue had an inscape window open over her plate, the shack, now floodlit from the Banshee, visible in it.

Suddenly the window went gray and the words SIGNAL LOSS appeared in it. Rue blinked at it in puzzlement for a second. Then she heard a sound like snakes hissing and the interceptor seemed to shudder under her.

The pilot shot past her, cursing loudly. He yanked himself into his seat and now Sola was yelling orders like there'd been a hull breach.

Hull breach! She dove for her own g-bed, waiting for the confirming spike of pain in her ears as pressure dropped. It didn't come, but she felt the ship turning under her. She reached over and punched the tactician's arm. "What's happening?"

"We lost forward sensors. We're flipping over to use the aft set."

"Did we hit something?"

"Don't know… no, it wasn't like that." Sola looked a bit gray. "I think it was a laser. The Banshee must have spotted us."

"I'm setting up a dusty plasma shield," said the pilot. Rue's window came back on-line, showing a turning starfield. A glowing orange haze appeared and slowly thickened until the stars vanished.

"How am I supposed to see through this?" said Rue.

"Telescope's off-line," muttered the pilot. "Hull registered a two thousand degree temperature spike. Definitely a laser."

"What's the Banshee doing?"

Sola had a bunch of windows open. "…Nothing," he said, puzzled. "It hasn't varied its radar ping. No movement, no heat signature from weapons fire."
