The Eternal Flame

hand in greeting, and they returned the gesture. The springs would help the beacon clear the ramp safely, but most of its velocity would come from the rotation of the Peerless. In less than a year it would be three gross separations away—by then, Tamara hoped, just one point in a huge, sparse grid of identical devices drifting out across the void, all flashing in a miserly but predictable fashion. Anyone could orient themselves by the stars, but knowing your position was something else entirely. The ancestors had had their sun and their sister worlds to help them navigate, but if the travelers wanted to leave the Peerless without losing their way they would have to create their own guiding lights, on a scale commensurate with their intended journey.

Viviana set the triggering time on the clock beside the launch plate. It was impossible to choose the beacon’s trajectory as precisely as they’d need to know it, but the timing of its launch would be enough to ensure that it was traveling in more or less the right direction. Viviano reached into the beacon and disengaged the safety lever, allowing sunstone and liberator to enter the flare chamber the next time the air valve was opened. Then they both moved back behind the plate, out of harm’s way.

Tamara watched by starlight as the launch clock’s three fastest dials spun toward the chosen alignment. The figures on her skin tingled with recognition just before the faint shudder of the springs reached her through the rock. The beacon shot clear of the ramp and plummeted out of sight. Tamara rushed forward to the edge and peered down, but the machine was already invisible, a speck of darkness lost among the star trails. She glanced back at the clock and pictured Roberto’s fingertips on the same dials spinning beside the observer’s bench: one hand following the time, one on the scope’s coordinate wheels. At the other end of the Peerless another colleague would be doing the same.

When the flash came Tamara raised an arm to cover her eyes, though the light was already fading before she’d moved a muscle. Powdered sunstone burned fast and bright; Roberto would have been using a filter, but the stab of light would have burned the measurements at his fingertips into his brain. Tamara was dazed and half- blinded, but now she could believe that the beacon’s light would be visible across the void, even through the Gnat’s modest instruments—so long as nothing broke, nothing jammed, and no speck of orthogonal matter turned the machine into a fireball before the Gnat had even been launched.

There was no point waiting for the second flash; the rotation of the Peerless was tipping the ramp up, hiding the beacon behind her. But Roberto and his opposite number would have dozens of chances to repeat their measurements, triangulating a whole series of points along the beacon’s trajectory before the machine switched to its dormant state. After that, the next flash wouldn’t come until a stint before the Gnat’s launch.

Viviana and Viviano were already headed back to the airlock with the empty trolley. Tamara stayed at the edge of the ramp, one hand around her safety rope, gauging its reassuring tension. She would not be embarking on a fool’s mission; they would not be going blindly into the void. Long before the journey began they would have wrapped the space around them in light, in geometry, in numbers.

The wheat-flowers were opening as Tamara strode along the path that ran down the middle of the farm, the limp gray sacs unfurling until the petals’ red glow filled the whole chamber, overpowering the moss-light from the walls and ceiling. A faint scent of smoke hung over the field but no sign of the burn-off was visible.

Tamara reached out to brush the plants’ yellow stalks with her fingertips. Though the crops rose and fell, the farm itself seemed ageless, unchangeable. But she remembered her grandfather telling her that in his own parents’ life-time the sheer wall of rock on her left had been a soil-covered field. There had been no low ceilings then, no second, third and fourth farms stacked above them; no one had planned for centrifugal gravity when they’d first carved these chambers out of the mountain. Tamara sometimes found herself scandalously wishing that it would be as long as possible before the engines were fired again, sparing any of her immediate descendants the tedious job of reconfiguring the farm for a second and third time. Or perhaps by then some brilliant agronomist would have boosted the crop yield to the point where everyone could live off stored grain for the whole reversal stage, and the farmers could take a three-year holiday.

“Hello!” she called out, as she approached the clearing. There was no one in sight. She went to the store- hole and took out a small bag of flour, left over from grain she’d milled the day before.

Tamaro and Erminio arrived as she was finishing the loaves; they were both carrying scythes and lamps. The lamps were extinguished, but she could smell the smoke that still clung to their skin from a different kind of fire.

“How bad is it?” she asked.

“It’s under control,” her father assured her. “All within a few square strides, and all of that’s ash now.”

Tamara widened her eyes in relief. The wheat blight appeared on the back of the petals, close to the stem, making it almost impossible to spot when the flowers were open. The only way to catch it was to go around with lamps in the moss-light, inspecting the dormant flowers—and the only cure was to incinerate the afflicted plants immediately.

The two men sat and joined her in the meal she’d prepared. Tamara knew that they had their own store-hole nearby, and that they’d eat again as soon as she left in the morning, but a part of her was still able to ignore that abstract knowledge and stitch together a version of the family’s daily life comprised of nothing but her direct experience. Every evening she made three loaves and shared them with her father and her co, and her stores of grain and flour were always the same when she returned as when she’d left them, so she could tell herself a perfectly believable story where the three of them were all living in an equally austere fashion. She never for a moment forgot that it was fiction, but it still did more to make the situation tolerable than any amount of time spent pondering the ultimate consequences of giving in to her hunger.

“What’s happening with the beacon?” Tamaro asked her.

“It’s out there, at last!” Tamara recounted the details of the launch. “I heard from Roberto afterward, and it looks as if we got a good fix on the trajectory. So we’ll go ahead and follow with the others. The next one should be ready in less than a stint.”

As she spoke, she could see Tamaro growing uneasy. “I’m sure you can get the navigation system working,” he said. “But I’m still worried about that idiot Ivo.”

Tamara wondered if she’d unwittingly libeled the man; it was hard to resist joking about his lizard paper, but he certainly knew his field. “He’s a bit eccentric,” she said, “but he’s not an idiot.”

“He’s reckless.” Tamaro brushed crumbs from his tympanum. “Once a man’s seen his grandchildren, his own life means nothing to him.”

“That’s a stupid generalization,” Tamara replied, irritated. “Anyway, he’s not making all the decisions about the Gnat. The Council has appointed its own experts to vet everything we’re planning to do: people who won’t be on the expedition themselves, so they’ll have a different perspective.”

Erminio said, “How does someone get to be an expert in a substance they’ve never even seen?”

“And if they won’t be on the Gnat,” Tamaro added, “why should they care what happens to its passengers?”

“Make up your mind,” Tamara retorted. “Is it Ivo who’s reckless, or the advisers who’ll be staying behind?”

“They’ll both be more worried about capturing the Object than they will be about who lives or dies,” Tamaro replied heatedly. “Once this precious lode of orthogonal matter is suspended in the void, the Gnat will have done its job, won’t it?”

Tamara hummed with frustration. “Will you listen to yourself? Capturing the Object will require an exercise in precision rocketry. The Gnat will only end up damaged if we lose control of the situation. The two outcomes are mutually exclusive! You don’t achieve the first one by risking the second.”

Tamaro tipped his head slightly, conceding that he might have gone too far. “The fact remains, though: Ivo’s an old man, he’s lived his life. I’m not saying that he’s planning a suicide mission, but when he weighs up the risks against his chances of glory, he’s not going to take the most cautious route.”

“So what do you want me to do?” Tamara demanded. “Renege on my offer to bring him along? Tell him to delegate the job to a younger colleague with more to lose?”
