Ramiro scratched the skin around his fetter; it had been itching horribly for the last three days. Despite his pleas, Greta had insisted that he remain in chains even when they were interviewing candidates. He was beginning to wonder if he’d be kept in restraints even once he was on the Surveyor itself.

“The planet Esilio is orbiting a massive star,” Agata enthused. “But we’ll be blind to the light of that star; it will appear to us as nothing but a pale gray disk. That combination offers the perfect conditions for the observations I want to carry out.”

Ramiro had no idea what she was talking about, but they hadn’t seen anyone else with pro-messager credentials half as eager to make the journey. “Go on,” he said.

“If gravity is really just the curvature of four-space,” Agata continued, “then light that passes close to this star will be bent less than it would be under Vittorio’s theory. I know that sounds strange, but in Lila’s theory the curved space around the star makes centrifugal force stronger than it would be in flat space, so it’s harder to bend the light’s trajectory. With no glare to hamper the observations, we could measure the apparent positions of home-cluster star trails as they approach the edge of this star’s disk, and see which predictions turn out to be correct.”

She summoned an illustration of the phenomenon onto her chest.

“I’ve exaggerated the scale of the effect here,” Agata admitted, “but it would certainly be measurable with a small telescope.”

Ramiro thought this sounded harmless enough. The last applicant who’d claimed to be drawn to the mission by the chance to carry out a scientific project had wanted to experiment with exotic methods of pulverizing Esilio’s surface from orbit, in order to impose their own entropic arrow as firmly as possible. Listening to the woman’s wish list of weapons she hoped to load onto the Surveyor had been entertaining, but a theodolite or two would probably be easier to sell to the Council than a flying armory.

Greta, though, was as suspicious as ever. “You’d be willing to give up twelve years of your life, just to observe this minor optical effect?”

“I would,” Agata replied. “The precise angle by which a beam of light is deflected by a star might not sound important, but until we know for sure whether matter and energy really do curve four-space, the answers that we’re struggling to find to much bigger questions—the geometry of the cosmos, the reasons for the entropy gradient—will just be guesswork.” She paused, then added, “I also think the mission’s worthwhile for its own sake. If there are people who can’t live with the majority’s decisions on the Peerless any more, we should let them leave.”

“I understand that you were close to one of the instrument builders?” Greta pressed her. “To Medoro?”

“Yes.”

“So wouldn’t you rather see his killers punished?”

“Did I miss the news where they were caught and tried?” Agata replied sarcastically. “If it’s a choice between letting them migrate to Esilio and having them around to do the same thing again, I’d rather get rid of them.”

“So you see this as protecting other travelers?”

“Other travelers,” Agata agreed, “and the messaging system itself. I debated Ramiro in the campaign—and I still believe every word I said about the benefits of the system.”

“How old are you?” Greta asked.

“A dozen and ten.”

“You won’t have many years left when you return, and you’ll have aged more than all of your friends. Do you really want to spend the best years of your life inside a vehicle the size of your apartment—in the company of the man who lost that debate, but then turned around and tried to extort us into giving him his way regardless?”

Ramiro had developed a thick skin when it came to Greta’s characterizations; much as she enjoyed it, her main goal seemed to be to spur his would-be traveling companions into venting their hostility now, instead of waiting until they had the opportunity to carve him up and toss the pieces into the void.

Agata gestured toward Ramiro’s chains. “I can see that you don’t trust him—and nor do I, completely. But he was an honest opponent in the debate, and I don’t blame him for my friend’s death. This mission needs people from both factions or it isn’t going to fly at all.”

“That’s a nice sentiment,” Greta replied condescendingly. “But are you sure you’re ready for the cost of putting your own flesh behind it?”

In response, Agata only grew more stubborn. She said, “The first travelers left their friends and family behind forever. Between the chance to learn how gravity works and the chance to make the Peerless safer, I’m willing to put up with a few years of hardship.”

“It’s coming together nicely,” Verano said, leading Ramiro and Greta across the echoing space of the workshop. Verano had the gaunt frame of a Starver, but he displayed no lack of energy or enthusiasm. Ahead, slowly descending from the ceiling’s horizon, the fat disk of the Surveyor sat balanced on its rim within a cage of scaffolding, the polished hardstone glinting in the light of three banks of coherers angled up at it from the floor.

As they approached, it became clear that the gradual revelation would fall short of exposing the whole disk. Verano’s team had had to cut a rectangular hole in the ceiling to make more room, leaving the top third of the craft poking up into that slot.

Ramiro tried to hang back, suddenly reluctant to get too close. Greta wound his chain lengthwise around her forearm a few times to take up the slack and pulled him forward. “Come and see your new prison,” she whispered. “This is what you asked for, isn’t it?”

The Surveyor looked a great deal larger than his cell, but most of the interior was destined to be taken up by essential stores or machinery. The main engines were already in place—six beautiful dark panels packed with ultraviolet rebounders, symmetrically arranged around one face of the disk—but the team had yet to install the cooling system, which for a trip of this duration meant a complete sunstone gasification plant, not a few tanks of compressed air.

“Do we still get to call this a gnat?” Ramiro asked.

Verano buzzed. “Probably not. But this is where my grandfather built the original—the one that made the first trip to the Object.”

“You’re Marzio’s grandson?”

“Yes.”

Ramiro felt a slight diminution of his anxiety. Marzio’s skills were legendary, and though talent of that kind was unlikely to be heritable, much of its legacy could still be passed down the generations through teaching and experience.

“We adapted this from a design that a group of engineers developed a few years before the turnaround,” Verano explained. “It was meant as a proof of concept for a shuttle running between the Peerless and the home world, but they still planned it down to the last detail.”

“That’s what I call getting in early. What did they call the design?”

“The Uniter, I’m afraid,” Verano replied. “If we do start mass-producing these things, I suppose we’ll have to think of a more apt generic name.”

“Deserters?” Greta suggested.

Half a dozen artisans clung to the scaffolding, working with everything from chisels to coherers. Ramiro moved closer; Greta followed, letting out his chain. Verano invited him to climb a ladder leading up into the atrium so he could look down into the hull. When he reached the top he could see the living quarters through a gap in the rim: four absurdly small rectangles, delimited by a series of slots in the presently vertical floor that the masons would use to insert the walls. Off to the side was a pantry, larger than all four rooms combined. They wouldn’t have the space to grow crops of their own. If one live skewer-worm got into their grain store, they’d end up starving to death.

“Twelve years in this?” Ramiro hummed softly. “What was I thinking?” He began descending.

“It’s too late to back out now,” Greta replied. “Change your mind, and it will be twelve years with no change of scenery.”

Ramiro doubted that. There was an election approaching, and the Councilors had to be coming under pressure over the internments. The investigation into the bombing might yet drag on for years—and in some people’s minds every anti-messager would have to share the guilt, regardless—but there were too many voters who had friends or relatives locked up for no good reason for the Council to remain oblivious to their anger.

He paused halfway down the ladder. “I’ve always admired Eusebio. He was smart enough to sell the Peerless to his friends as the home world’s salvation, and then stay behind while they did all the real work. Stay behind and stay young: that should be my motto, too.”

Greta was not amused. “So who are these people that could spare you the trip? Agata’s the sanest of the pro-messagers so far—and we’d better hope Azelio’s family don’t talk him out of it, because we’re never going to find another agronomist. The two of them might just hold together as a crew, but they’re not going to do this on their own. If you pull out, the whole thing will be over.”

“Ramiro?”

Ramiro turned to see a woman approaching in the distance. She was limping slightly, and tall enough that from his own elevated position her face was hidden by the curve of the workshop’s ceiling. Her lower torso showed all the signs of a recent shedding, the shrunken flesh leaving her hips painfully unbalanced.

He was still struggling to recognize her voice, distorted by the strange acoustics, when her head finally cleared the horizon. “Tarquinia?” Ramiro climbed down to the floor, holding his chain with one hand to relieve the pressure. Then he began walking toward his friend, leaving Greta to decide for herself if she wanted to accompany him. She dropped the chain and let him go.

As he drew closer, the extent of Tarquinia’s depletion became clearer. Ramiro doubted that even a woman who’d been through the whole ordeal herself could look upon skin stretched and sutured over such a deep absence without flinching.

“You didn’t tell me,” he complained. “When did this happen?”

“Two days ago.”

“How’s your daughter?”

“My son is fine,” Tarquinia corrected him. “His name is Arturo.”

“You had a son first?”

“No. His sister was born three stints ago.”

Ramiro was shocked; he’d never heard of anyone choosing such a punishing schedule. He didn’t want to question the wisdom of her timing, but it couldn’t go completely unremarked. “How’s your brother coping?”

Tarquinia was amused. “Men used to raise four infants at once. With his uncle to help, two is nothing.”

“That’s easy for a woman to say.”

“Easy?” She looked down at her stitches.

“I didn’t say you had an easy time inflicting it on them. So what are you doing here? You ought to be resting.”

“Someone told me you were down here,” Tarquinia explained, “so I thought I’d try to catch you. I asked at the prison but they wouldn’t let me visit there. And I wanted to take a look at the Surveyor anyway, before I make it official.” She staggered slightly; Ramiro stepped forward so she could rest a hand on his shoulder. “That walk from the entrance was the hardest part,” she said. “I forgot how high the gravity is down here.”

“I’m surprised your legs haven’t snapped off.” Ramiro glanced back toward the Surveyor. “Make what official?”

“My application for the pilot’s position.”

Ramiro wasn’t sure how to take that. “Are you serious?”

Tarquinia gestured at her skeletal hips. “I didn’t clear myself of familial obligations for the sake of a joke.”

“Familial obligations?” Ramiro had never heard her talk so bluntly before.

“What—you think I’m being cold?” Tarquinia didn’t sound offended, just curious as to how he viewed her actions.

“It’s your brother who’ll be raising them,” Ramiro conceded. “Still, four years is a long time at that age.”

“Did the ancestors miss their mothers?” Tarquinia asked. “Or mothers their children?”

“Why wouldn’t they? The only people more perfect than the dead are the yet-to-be-born. But my mother had nothing to do with me or my sister, and that didn’t bother us.”

“Mine was the same.” Tarquinia straightened her body. “So are you going to show me this thing?”

Ramiro led her over to the hull and introduced her to Verano. Greta caught his eye; she looked smug for some reason. But it was Ramiro who’d gained an ally, not her.

“How are we meant to navigate?” Tarquinia asked Verano. “We’re not going to have time to set up a grid of beacons far enough apart to be useful, and there’s only so much positional information we’ll be able to extract from home-cluster star trails.”

Verano glanced at Greta. Greta said, “Once you’ve made an application and agreed to the confidentiality conditions, we can discuss whatever details you like.”

Tarquinia was taken aback for a moment, but she accepted the reply without complaint.

Verano took Tarquinia closer to the hull and the two of them began chatting with some of the masons. Greta turned to Ramiro. “Still thinking of doing a Eusebio?” she asked. “Letting your comrade fly alone?”

“I wasn’t serious,” he protested.

“Of course not.” Greta reached down and picked up the end of his chain. Ramiro groped for an insult, but his mental scrabbling yielded an entirely different weapon. “You’ve got a working version of the camera,” he realized. “What is it—some prototype that survived the bombing?” How else would they navigate to the edge of the orthogonal cluster, if not by imaging the time-reversed stars?

Greta said, “You don’t get to ask questions like that.”

Ramiro was sure now that he’d guessed correctly. Tarquinia had probably worked it out too. It wasn’t something he’d want the whole mountain to know—lest the same deranged killers behind the bombing decided to target the Surveyor itself—but it was always pleasing to be a little less in the dark than his jailers wished.

“You’d better think up a good cover story,” he suggested. “A new generation of accelerometers, maybe? I’ve been a bit distracted, but other people won’t be so slow.”

Tarquinia was buzzing with mirth; Verano had just explained the way the Surveyor’s toilets would work. Ramiro was unspeakably happy at the thought of having her along on the journey—and if he was trapped now, so be it. He’d wanted to stay strong enough not to back out, and if Tarquinia’s presence would shame him into honoring his commitment that was nothing to lament.

Greta said, “All I’ve ever done is work to keep the Peerless safe. I think you can trust me to do the same for the Surveyor.”

“Perhaps.” Ramiro couldn’t stop himself goading her when he had the chance, but she’d already proved her resolve to make the mission successful. “And I think you can trust me not to flee custody and disappear into some anti-messager safe house.”

“Perhaps.” Greta took a key from a pocket in her thigh, then reached over and unlocked the fetter. Ramiro slid the chain free, then eased the bar out of his flesh and let the whole thing clatter to the floor.

He watched Tarquinia haltingly ascend the ladder so she could look down into the Surveyor for herself. Six years to Esilio, six years to come back, then six more if he joined the migration. He’d be at least three dozen and four years old by the time he was walking free across the plains of his new home—and he’d need to outlive the average male in his line by five years to get that far.

He’d managed to constrain his entire future as rigidly as any message encoded in time-reversed light could have done. But if he looked at the alternatives honestly, they were all worse.
