The first training session lasted nine seconds.

  Meric told Ethan to stand in the center of the courtyard. Ethan stood. Meric circled him once, hands behind his back, then stopped three paces to his left. Ethan tracked him with his peripheral vision, weight balanced, breathing steady. Everything he'd learned across four doors told him to keep his eyes on the most dangerous thing in the room and not look away. Then Meric was behind him.

  Not moved-fast behind him. Not I-blinked-and-missed-it behind him. Meric had been three paces to his left and then he was behind him and Ethan's brain couldn't connect the two states with any motion in between. A palm hit him between the shoulder blades—not hard, just firm enough to send him stumbling forward. His foot caught on the uneven stone and he went down, catching himself on his hands.

  "Up," Meric said.

  Ethan got up.

  Meric was to his right now. Ethan didn't bother tracking how he'd gotten there. He set his feet, centered his weight—

  The ground hit him in the face.

  This time the palm caught his ribs from the left, turning his balance inside out. He went down harder, hip and elbow taking the impact. The stone was cold and gritty and smelled like old rain.

  "Up."

  Up. Reset. Feet set. Weight centered. He didn't know where Meric was. Didn't waste time looking. Just stood and waited for the next one.

  It came from directly in front of him, which should have been impossible because he was looking directly in front of him and Meric wasn't there and then he was. Two fingers tapped the center of Ethan's chest—barely any force, almost polite—and his legs folded. He hit the stones for the third time in nine seconds.

  "Up."

  Ethan got up. He got up fourteen more times over the next hour. By the end, his palms were raw, his left hip was turning colors, and he'd successfully identified the direction of exactly zero attacks. Meric hadn't broken a sweat. His breathing was the same as when they'd started.

  "You fall well," Meric said. It was the first thing he'd said other than up. "Most people try to catch themselves. Brace, tense, fight the ground on the way down. You just go down and get back up. Whoever taught you that did you a favor."

  "She did a lot of those."

  "She sounds unpleasant."

  "She saved my life. Repeatedly. Often by making me miserable first." Ethan wiped grit from his palms on his trousers. "She'd have liked you."

  "I doubt it. I'm not very likeable." Meric turned toward the buildings. "Same time tomorrow. Eat something. You look like you're about to fall over, and I'd like that to be my doing."

  The second week was worse than the first. The third was worse than the second. By the end of the first month, Ethan had catalogued forty-seven different ways to hit the ground and could identify none of them in advance.

  But he was noticing things.

  Not the attacks themselves—those were still invisible, still instantaneous, Meric disappearing from one position and existing in another with nothing connecting the two. What he noticed was what happened before the attacks. The air moved. Not much. A displacement so faint it was less than a breeze and more than nothing—the kind of shift you'd feel on your cheek if someone opened a window in the next room.

  On day thirty-one, Meric appeared on his left and Ethan was already turning.

  He still got hit. The palm caught his shoulder and spun him sideways and he went down on one knee, hard. But he'd been turning the right direction. One correct read out of maybe two hundred attempts.

  Meric didn't congratulate him. He stood where he'd appeared, hands behind his back, pale eyes flat.

  "Again," he said. The next attack came faster.

  The meal that changed things happened six weeks in.

  Ethan had been eating alone since he arrived—bowls of grain and whatever vegetables the temple's small garden produced, left on a stone ledge outside the room he'd been given. Functional food. The kind of meals that existed to keep a body running and had no other ambitions. He'd eaten worse in the cave with Stephanie, which was saying something, because Stephanie's approach to cooking could be described charitably as "thermal."

  On the forty-second evening, Meric appeared at his door with two bowls and a look on his face that suggested he was already regretting this decision.

  "I made stew," he said.

  Ethan took the bowl. Looked at the contents. The liquid was grey. There were chunks of something in it that might have been potato or might have been a root vegetable that had given up on its identity. The smell was not actively offensive, which was the nicest thing he could say about it. He took a bite.

  "It's terrible," Ethan said.

  "I know."

  "The vegetables aren't cooked through."

  "I know that too."

  "Did you put salt in this?"

  "I don't believe in salt."

  Ethan looked at him. Meric's scarred face was perfectly straight, but there was something happening at the corners of his mouth that was fighting very hard not to become a smile.

  "You don't believe in salt," Ethan repeated.

  "Salt is a crutch. If the food can't stand on its own, it doesn't deserve to be eaten."

  "This food can't stand on its own. This food is lying in a ditch."

  The thing at the corners of Meric's mouth won its battle. The smile was small, reluctant, and genuine. It cracked something in his face that had been set for a long time.

  "I can kill a man sixteen different ways with a soup ladle," Meric said. "I cannot make soup. This has been a source of personal frustration for longer than you've been alive."

  They sat on the stone ledge and ate terrible stew and Meric told him about a student he'd had ten years ago who'd been convinced—absolutely certain, would not be dissuaded—that the secret to the Hidden Step was to hold your breath. The student had spent three weeks passing out in the courtyard before Meric had the heart to tell him the technique had nothing to do with breathing.

  "What happened to him?" Ethan asked.

  "Became a very competent baker. Lives in the valley. Brings bread up twice a month. Finest sourdough I've ever had." Meric scraped the bottom of his bowl. "Not every student becomes a killer. Some of them just learn to fall well and make bread. Those aren't the worst outcomes."

  Ethan ate his terrible stew and didn't say anything for a while. The evening was cold and clear and the stars above the Shattered Spine were thick enough to blur together at the edges.

  "My wife used to say I collected skills the way other people collect stamps," he said. "She meant it as a criticism. I think she was right."

  "Used to?"

  "She's not my wife anymore. Hasn't been for a long time."

  Meric nodded. He didn't ask why or offer sympathy or make any of the noises people make when someone mentions a failed marriage. He just nodded—a fact received, no commentary required.

  "Tomorrow," Meric said, standing, "I'm going to show you something that will make the last six weeks feel like a holiday."

  "Looking forward to it."

  "You shouldn't be." He took both bowls. "I'll make the stew again next week. You can teach me about salt."

  He walked away. Ethan sat on the ledge and watched the stars and thought about the fact that for the first time since entering the Starforge, he didn't want the challenge to end quickly.

  Meric showed him Shadow Lightning on day forty-three, and Ethan's understanding of what was possible broke cleanly in half.

  It wasn't speed. Speed was fast movement through space—point A to point B with everything in between. Shadow Lightning didn't have an in-between. Meric opened a tear in the air the size of a fist and stepped through it and came out somewhere else. The tear was there and gone so fast that Ethan's eyes couldn't hold it, but his skin could feel the displacement. A wrongness—a stutter in the air where continuity should have been.

  "This is what I've been using on you," Meric said, standing in the center of the courtyard. "At low intensity. Controlled. Enough to move around you without you tracking it." He paused. "This is what it looks like at full speed."

  This tale has been unlawfully obtained from Royal Road. If you discover it on Amazon, kindly report it.

  He vanished.

  Reappeared six feet to the left. Vanished. Reappeared behind a pillar across the courtyard. Vanished. Reappeared directly in front of Ethan, close enough that his breath moved Ethan's hair, then was gone again before Ethan could flinch. Four more positions in the space of a heartbeat, each one coming from a direction that had nothing to do with the last, the air popping and stuttering with each displacement.

  Meric stopped where he'd started, hands behind his back. Breathing normally. The courtyard was still ringing with the absence of him—displaced air settling back, finding its equilibrium in slow, uneven waves.

  "You want to learn agility," Meric said. "This is what agility looks like when you stop thinking of it as movement and start thinking of it as choice. Every position is a decision. Every displacement is a commitment. The technique isn't physical. It's mental. You decide where you are, and the space agrees."

  "And if the space disagrees?"

  "Then you're inside a wall, and we have a very short funeral."

  Ethan had no ability to replicate this. His body lacked whatever cultivation allowed Meric to tear holes in reality. He was never going to learn Shadow Lightning. That wasn't the point. The point was learning to survive it.

  It took him eleven months.

  Eleven months of getting hit from directions that didn't exist, of reading displacements that lasted less than a tenth of a second, of training his body to react to information his conscious mind couldn't process fast enough to use. Meric hit him thousands of times. Ethan hit the ground thousands of times. He broke two fingers, cracked a rib, sprained his left ankle so badly it swelled to the size of a small melon and Meric made him train on it anyway because, as Meric put it, "the enemy doesn't schedule around your injuries."

  On the three-hundred-and-thirty-first day, Meric appeared on Ethan's right and Ethan wasn't there.

  He'd moved. Not fast—not by Meric's standards, not by any measurable standard. But he'd felt the displacement a fraction of a second before Meric materialized and his body had translated that information into a half-step to the left that put him outside the strike zone. Meric's palm passed through the space where his shoulder had been and hit empty air.

  They both stood still for a moment. "How?" Meric said.

  "Your portals aren't random. They can't be—there's a cost to each one, a recovery period. Fractions of a second, but real." Ethan rolled his shoulder, the one that was used to getting hit. It felt strange without the impact. "You favor certain angles when you're tired. Certain distances when you're pressing an advantage. The chaos is a mask for patterns you don't know you have."

  Meric stared at him for a long time. His pale eyes did something Ethan had never seen them do: they went warm.

  "Well," he said. "That's annoying."

  Annoyed, yes. But his eyes were still warm, and underneath the annoyance his voice carried something closer to pride than frustration.

  The years settled into rhythm after that. Training every morning. Ethan getting better in increments so small they were only visible in aggregate—not breakthroughs, just accumulation. Showing up every day and being slightly less bad than the day before. Evenings on the cliff edge, watching the sun go down behind the western peaks. Terrible stew that got marginally less terrible over time, because Ethan had taught Meric about salt and Meric had grudgingly admitted it was an improvement, though he maintained this was a personal defeat.

  In the second year, Meric told him about a job that had gone wrong.

  "Early career," Meric said, legs dangling off the cliff edge, which was a profoundly casual position for a man who could relocate his entire body with a thought. "I was supposed to acquire a document from a magistrate's office. Simple extraction. In and out. Except the magistrate had a cat."

  "A cat."

  "A very large cat. With opinions about strangers." Meric's face was straight but his voice had the careful cadence of someone setting up a story he'd told before and still enjoyed. "I opened a portal into the office, stepped through, and immediately stepped on the cat's tail."

  "The cat screamed. I screamed. The magistrate woke up. His wife woke up. His wife had a crossbow."

  "The magistrate's wife had a crossbow."

  "Loaded. Under the pillow. I still don't know why. But I can tell you that a woman in a nightgown with a crossbow is significantly more frightening than any magistrate, and I have been shot at by professionals." Meric scratched the scar beneath his left eye. "She got me here. With a bedside candlestick, not the crossbow. The crossbow went into the ceiling. The cat went out the window. I went out behind the cat. I did not get the document."

  "Did you go back?"

  "I sent a student. The student brought fish for the cat." A pause. "The student also didn't get the document. But he and the cat became quite close."

  Ethan laughed. It was the first time he'd laughed in the Starforge, and the sound surprised him enough that he stopped, which made Meric raise an eyebrow.

  "I had a project once," Ethan said. "Bridge retrofit. Small town, tight budget, the kind of job where everything has to work the first time because there's no money for a second try. I spent three months on the calculations. Triple-checked everything. Drove to the site for the final inspection and the bridge was six inches too short."

  "Six inches."

  "Six inches. The surveyor had measured from the wrong benchmark. Three months of perfect engineering applied to the wrong starting point." He looked out at the valley. "My boss asked me what happened and I told him the bridge was right and the river was in the wrong place."

  "Did he appreciate that?"

  "He did not."

  They sat in the fading light and Meric didn't say anything about how they were friends now, or how this felt different from the teacher-student relationship, or any of the things people say when they're narrating their own lives instead of living them. He just sat there, legs dangling over a drop that would kill a normal man, and Ethan sat beside him, and the silence between them was the comfortable kind that only exists between people who've stopped performing.

  In the third year, Ethan started teaching.

  Junior students. The ones still learning to survive their first weeks. He taught them what Meric had taught him: how to fall without fighting the ground, how to read displacement, how to get up one more time than you went down.

  One of them was a girl, maybe sixteen, with sharp elbows and a jaw set so tight it looked wired shut. She hit the courtyard stones forty times the first session and got up forty-one—the extra one because she'd gotten up before the first hit landed, just from the look in Ethan's eye.

  He watched her get up the forty-first time and something turned over in his chest. Not memory, exactly. Recognition. The stubbornness that bordered on stupidity, the refusal to let the ground win. She stood up mad instead of hurt every single time.

  Stephanie would have adopted her on the spot.

  He made her run the drill again. She hit the ground twelve more times and got up thirteen. By the end of the session, her palms were bleeding and she hadn't asked to stop once.

  "You're doing it wrong," she told him on her way out, holding her hands under the courtyard's cold-water pump. "You're supposed to tell me what I'm doing wrong. That's what teachers do."

  "You're getting up," Ethan said. "That's the lesson. Everything else is refinement."

  She gave him a look that said she thought this was a deeply unsatisfying answer, and walked away dripping.

  Meric, who had been watching from the doorway, said nothing. But his expression had the particular quality of a man who was seeing something he recognized and wasn't sure whether to be pleased or afraid.

  In the fourth year, Meric flinched.

  It happened during a routine evening. A trader had come through the valley—the kind of circuit merchant who appeared twice a year with goods the temple couldn't produce itself. Nothing unusual. Meric was reviewing the man's inventory in the courtyard when the merchant mentioned a town name. Kareth. A border settlement two hundred miles southeast, known for wool and not much else.

  Meric's right hand closed. Not a fist—a contraction. The fingers pulled inward a quarter-inch and held there for two seconds before releasing. His voice didn't change. His face didn't change. The conversation continued without interruption, and the merchant noticed nothing.

  Ethan noticed.

  He filed it the way he filed everything: clean, unsorted, waiting for a second data point to give it direction. Everyone had triggers. Everyone had places or words that landed differently than they should. It didn't mean anything until it meant something.

  The second data point came three months later.

  Meric was teaching a lesson on situational awareness. Standard material—reading a room, identifying exits, cataloguing threats. The kind of thing Ethan had been doing instinctively since the cave and now understood the formal architecture of. Meric was good at this. Clear, precise, building from principle to application with nothing wasted between.

  "Awareness is obligation," Meric said, pacing the training hall. "When you see a threat, you own it. Not tomorrow. Not when it's convenient. The moment you see it, it belongs to you, and what you do with it defines what kind of person you are."

  His voice changed on the last sentence. Not louder or softer. Flatter. The cadence shifted from teaching to reciting—from something he was explaining to something he was repeating. Words he'd said to himself before, many times, in a context that had nothing to do with training.

  He caught himself. Moved on. The lesson continued. The students noticed nothing. Ethan noticed.

  Two data points. A town name that made his hand close. A principle about obligation that he'd lived before he taught it. The engineer's mind did what it always did: it drew a line between the points and extended it into the dark and didn't like where it was heading.

  He didn't ask. Not yet. Meric would tell him when Meric was ready, or he wouldn't, and either way the line would keep extending.

  The fifth year began on a morning cold enough to turn breath into cloud.

  Ethan was in the courtyard running drills with a junior student when one of the older apprentices came through the gate at a pace that was faster than walking and trying not to look like it. His name was Callun, and he was the kind of student who took himself seriously enough that hurrying embarrassed him.

  "Someone at the gates," Callun said. "Not a merchant. Not local. He asked for the master by name."

  "Name?" Ethan asked.

  "Wouldn't give one. He's old. Civilian. Carrying a leather bag like it's the only thing keeping him upright."

  Ethan looked across the courtyard. Meric was at the far end, adjusting a student's grip on a practice blade. He hadn't heard Callun—or if he had, he hadn't reacted.

  "I'll tell him," Ethan said.

  He crossed the courtyard. Meric looked up as he approached, and whatever was on Ethan's face made the adjustment stop mid-motion. Meric straightened. Let the student's hand go. His pale eyes moved past Ethan to Callun, still standing by the gate, and then to the gate itself, where presumably someone was waiting.

  Something happened in Meric's face. Not a flinch this time. Deeper. The blood left his cheeks in a slow tide that started at his jaw and climbed, and his hands—those precise, certain, impossibly steady hands—went still in a way that was different from their usual stillness. The stillness of a man who was holding himself together by not moving.

  "I need to ask you to do something you won't want to do," Meric said.

  "What?"

  "Stay."

  Ethan looked at his friend—his teacher, his sparring partner, the man who couldn't make soup and told stories about cats and had taught him to read the space between moments—and saw something he hadn't seen in five years of watching Meric Der'aydies navigate the world with absolute control.

  Fear.

  "I'll stay," Ethan said.

  Meric nodded once. Walked toward the gate. His stride was even and unhurried and his hands were at his sides and he looked exactly the way he always looked, except that Ethan knew him well enough now to see the difference between a man who was calm and a man who had decided to be calm because the alternative was coming apart.

  Ethan followed him to the gate. The man on the other side was old. Not elderly—weathered. The kind of old that comes from decades of outdoor work and too little sleep. He had a farmer's hands, thick-knuckled and cracked at the joints, and they were wrapped around the strap of a leather satchel that hung from his shoulder. The satchel was worn soft from years of handling, its buckles dull with use. Whatever was inside it was heavy enough to pull the strap taut.

  He looked at Meric. Meric looked at him. Neither of them spoke for a long time.

  "You know who I am," the man said. His voice was quiet. Tired. The voice of someone who had been walking for a very long time and was almost at the end.

  "No," Meric said. "But I know why you're here."

  The man's grip tightened on the satchel strap. His hands were shaking. Not from anger. From the weight of thirty years pressing down on knuckles that had never been built for this kind of carrying.

  "My name is Dorhen," he said. "I think we should talk."

  Meric's pale eyes held the man's face for a breath. Two.

  "Yes," he said. "I think we should."
