On schedule, Washen’s team climbed into their six popup shelters, stripped out of their field uniforms, then lay awake, listening to the steady buzzing of the jungle, counting the seconds until it was time to rise again.
They sat in the open at breakfast, in a neat circle, and gazed up at the sky. A shifting wind had carried away the clouds, bringing hotter, drier air and even more fight. The chamber’s distant wall was silvery-white and smooth and remote. The captains’ base camp was a dark blemish visible only because of the clear air. With the distance and the glare, the bridge had vanished. If Washen was careful, she could almost believe they were the only people on the world. If she was lucky, she forgot that elaborate telescopes were watching her sitting on her aerogel chair, eating her scheduled rations, and now, with her right hand, scratching the damp back of her very damp right ear.
Diu sat on her right, and when she glanced at him, he smiled wistfully, as if reading her thoughts.
“I know what we need,’ Washen announced.
Diu asked, ‘What do we need?”
“A ceremony. Some little ritual before we can start.” She rose and walked down to the lake, not sure why until she arrived. Blackish water lapped against rusting stones. Bending at the knees, she let one of her hands dip beneath the surface, feeling its easy heat, and between the fingers, the greasy presence of mud and life. A stand of dome-headed bog plants caught her gaze, and beside it was a specimen trap. Filled, as it happened. Washen rose and wiped her hand dry against her uniform, then carefully unfastened the trap and brought it back to camp.
On Marrow, pseudoinsects filled most animal riches.
In their trap was a six-winged dragonfly, moonstone blue and longer than a forearm. With the other captains watching, Washen gently eased her victim from the netting, folding back the wings and holding the body steady with her left hand as the right wielded a laser torch. The head was cut free, and the body kicked, then died. Then she stripped the carcass of its wings and its tail, the fat thorax set inside their tiny field kitchen. The broiling took seconds. With a dull boom, the carapace split open. Then she grabbed a lump of the hot blackish meat, and with a grimace, made herself bite and chew.
Diu laughed gently.
Another captain, Saluki, was first to say, “We aren’t supposed to.”
A twelfth-grade named Broq added, “Miocene’s orders. Unless there’s an emergency, we stick to our rations.”
Washen forced herself to swallow.
Then with a wide smile, she told them, “And you won’t want to eat this again. Believe me.”
There weren’t any native viruses to catch, or toxins that their reinforced genetics couldn’t destroy or piss away. Miocene was playing the role of the cautious mother, and where was the harm?
Washen passed out the ceremonial meat.
Wanting to please her team leader, Saluki put the flesh to her tongue, then swallowed it whole.
Broq protested, then managed the same trick.
The next two, ship-born siblings named Promise and Dream, winked slyly at the sky and told Washen, “Thank you.”
Last to accept his share was Diu, and his first bite was tiny. But he didn’t grimace, and he took the rest of the carcass, his white teeth yanking out a fatrich chunk that he chewed before swallowing.
Then with an odd littie laugh, he told everyone, “It’s not too horrible.”
He said, “If my mouth just quit burning, I think I’d almost enjoy the taste.”
Ten
Weeks of relentless work made possibility look like hard fact.
Marrow had been carved from the ship’s heart. Or more properly, it was carved from the core of the young jupiter that would eventually become the Great Ship.
The world’s composition and their own common sense told the captains as much. Whoever the builders were, they must have started by wrenching the uranium and thorium and other radionuclides from the rest of the jupiter, then injecting them into the core. With buttressing fields, the world was compressed, its iron packed closer and closer before the exposed chamber wall was braced with hyperfiber. How that was accomplished, no one knew. Even Aasleen, with her engineering genius, just shook her head and said, “Damned if I know.” Yet billions of years later, without apparent help from the builders or anyone else, this vast machine was still purring along quite nicely.
But why bother with such a marvel?
The obvious, popular reason was that the ship needed to be a rigid body. Tectonics fueled by any internal heat would have melted the chambers and shattered every stone ceiling, probably within the first few thousand years. But why go to so much trouble and expense to create Marrow? If you’ve got this kind of energy at your disposal, why not just lift the uranium out into space where you could put it to good use?
Unless it was used here, of course.
Some captains suggested that Marrow was the nearly molten remnant of an enormous fission reactor.
“Except there are easier, more productive ways to make energy,” others pointed out, their voices more polite than gentle.
But what if the world was designed to store energy?
It was Aasleen*s suggestion: by tweaking the buttresses, the builders could have forced the world to rotate. With patience and power—two resources they must have had in abundance—the builders could have given it a tremendous velocity. Spinning inside a vacuum, held intact by the buttresses as well as a vanished blanket of hyperfiber, this massive iron ball would have served as a considerable flywheel.
Slowly, slowly, that energy was bled away by the empty ship.
Somewhere between the galaxies, the rotation fell to nothing, and that’s when the ship’s systems eased themselves into hibernation.
Aasleen went as far as creating an elaborate digital, as real to the eye as could be. In the early universe, heavy elements were scarce. The builders harvested the radionuclides from above and buried them here, and as Marrow grew hotter and hotter, its hyperfiber blanket began to decay. Degrade. And die.
Hyperfiber was rich in carbon and oxygen, hydrogen and nitrogen, every atom aligned just so and every bond strengthened with tiny predictable quantum pulses. Stressed past its limits, old hyperfiber would just fall apart, and the newly reactive elements would start dancing in celebration, giving life a reasonable chance to be born.
“It’s absolutely obvious,” Aasleen declared. “Once you see it, you can’t believe anything else. You just can’t!”
She made that dare at a weekly briefing.
Each of the team leaders was sitting in the illusion of a Master’s conference room, each perched in an black aerogel chair, sweating in Marrow’s heat. The surrounding room was sculpted from fight and shadow, and sitting at the head of the long pearlwood table, between imposing gold busts of herself, was the Master’s projection. She seemed alert but remarkably quiet. The expectation for these briefings was for crisp reports and upbeat attitudes. Grand theories were a surprise. But after Aasleen had finished, and after a contemplative pause, the Master smiled, telling her imaginative captain, “That’s an intriguing possibility. Thank you, darling. Very much.”
Then to the others, “Considerations? Any?”
Her smile brought a wave of complimentary noise.
Washen doubted they were exploring someone’s dead battery. But this wasn’t the polite moment to list the problems with flywheels and life’s origins. Besides, the bioteams were reporting next, and she had her own illuminations to share.
A tremor interrupted the compliments.
The image of one captain shook, followed by others. Knowing who sat where made it possible to guess the epicenter. When Washen felt the first jolt, then the rolling aftershocks, she realized it was a big quake, even for Marrow.
