The one Sylt hit went down hard and did not come back up.

  She was already past it. Her read on the next one came before the first had landed, tracking its position, its weight, the particular way it was loading its back leg. She closed in three steps. The contact was precise. It hit the hollow floor and stayed there.

  Two down. Four still moving in her half of the hollow.

  Thrynn had taken the larger cluster. Three of them, and they had read her fast, spreading wide to deny the angle. She did not chase the spread. She let them come to her. When the first committed she met the full weight of its approach and redirected it through the second. The collision bought her a half-second of disorganization and she used all of it. One down. Two adjusting. She was breathing harder than she should have been. Her left side had taken a hit two exchanges back that she had not fully absorbed. She did not favor it. She noted it and kept moving.

  Leya held the hollow's upper edge. She had repositioned twice since the pack split, reading the sight lines before anyone else did, placing herself where the back half of the hollow funneled toward a single point. The two that tried to flank through the right side of the hollow found she had already solved for them. She did not miss.

  Simon worked the remaining two in his half. They were faster than the others. Low to the ground, changing direction at angles that should have been inefficient, their coordination tight enough that pressing one always invited a response from the other. He did not press. He redirected. He kept the distance exact and let them exhaust their read on the gap between where he was and where they expected him to be.

  He tried the air pressure first. He had been working the idea since Vyrhold. The principle was clean enough: change the load in the air column just ahead of an incoming strike, use the differential to redirect the force before it arrived. Against a still target, in stillness, he had felt the beginning of something real.

  Here it produced nothing. The strike came through unaltered. He was already somewhere else and that had nothing to do with the experiment. He filed the failure.

  He tried the sound next. A different approach, same foundation. Resonance at a frequency intended to disrupt spatial read. He reached for it and found only absence. Whatever he was looking for was not accessible from here.

  He filed that too and kept moving.

  * * *

  Two bells earlier, Lukas had caught them outside Highmark Registry Hall. He did not stop walking when he found them. He adjusted his direction and they adjusted theirs and the conversation happened in motion, which Simon had already come to understand was how Lukas preferred it.

  "Since you're here and it doesn't seem like you're busy, I might as well use you." A pack running in the worked terrain east of the city walls. They had been pressing the district edge for three days. Highmark Registry had logged the sightings and had not yet dispatched.

  Lukas had the dispatch order before Registry had finished writing it.

  He did not explain how. He did not look like a man who explained how.

  "The runner that left Sword Hall this morning," he said, still not stopping. "You have four days. I would use two of them on this."

  He turned at the next intersection. He did not look back.

  * * *

  Back in the hollow, the pack's coordination began to fray.

  The two working Simon were reading the exchange correctly but not fast enough. One of them overcommitted to a line that had been available three exchanges ago and was not available now. Simon felt the shift in weight before the commitment finished. He was already inside it.

  He reached for the lightning.

  He had not planned to reach for it here. The opening was there and the form was there and his hands moved before the decision was complete. The discharge was partial. Not nothing. The intended path was not the path the current took. He felt it the moment it went wrong, the branching burn running back from both wrists, shallow and specific, the current mapping a route through him rather than through the air between them.

  His opponent went down.

  His forearms were wrong. He kept moving.

  On the other side of the hollow, Thrynn's second went down. She was on the third. Her left side was still compromised. He read the angle of the engagement and saw the problem before it became one.

  * * *

  They came from the back of the hollow.

  Two of them. The rest of the pack had been noise and pressure, fast and low, angled to exhaust before the real weight arrived. This was the real weight.

  The first carried a short blade and a buckler strapped to its forearm. Broad across the chest for its size. It moved without the skittering urgency of the others. It moved the way something moves when it has been told to hold ground and knows how.

  Behind it, further back, half-visible in the hollow's shadow, the second worked. Its hands were moving. It was not watching the fight. It was watching something else entirely.

  Simon felt the air shift. Not wind. Something underneath wind. A pressure change at the wrong scale, moving in the wrong direction. The particular wrongness of a system being pushed from outside its natural load path. He did not know what was being built back there. He knew the structure of what was being built. It was not finished yet.

  It would be finished soon.

  The one with the buckler moved toward Thrynn.

  Bad matchup. Thrynn had the strength for it but not the angle. Her left was already compromised. Taking something built to hold ground from a compromised side was a problem that would compound before it resolved.

  Simon moved.

  He did not announce the swap. He did not need to. Thrynn read the line of him coming and stepped wide, clearing the space, redirecting her attention to the pack's remaining pressure without breaking her own rhythm.

  The buckler adjusted. It was faster than it looked.

  He let it come.

  The light in the hollow was wrong. Not the working behind him. His own. He had been holding the attempt at the edge of his attention since the exchange began, not forcing it, letting the shape develop the way he had learned to let shapes develop since Vyrhold. The distortion was not what he had been reaching for. It was not complete. But it was something. The hollow's ambient light bent slightly at the wrong angle just to the left of his position. Not enough to blind. Enough to produce a half-second read problem for anything relying on its eyes.

  The buckler hesitated.

  Half a second.

  He closed inside it. His body already knew the rest. His opponent was built for impact and durability. He did not try to match either. He found the load-bearing point. He found the fault. He put everything he understood about how force travels through structure into a single application at the precise location where the structure could not manage it.

  The buckler went down.

  It did not get up.

  He was already turning.

  The one in the back had lost its anchor. Its hands were still moving but the rhythm had broken. It was reading the new shape of the engagement, recalculating, reaching for something it was no longer going to finish.

  A case of content theft: this narrative is not rightfully on Amazon; if you spot it, report the violation.

  Leya had been repositioning since the buckler committed. She had read the same shape he had, maybe earlier. She was at the hollow's far edge. She had the angle. She had the line.

  It turned. It read the threat.

  It was too slow.

  Leya did not miss.

  The hollow went quiet. The pack's pressure dropped all at once, the particular collapse of a coordinated system when the coordinating element is removed. The remaining kobolds read the new shape of the engagement and reached the correct conclusion.

  They ran.

  Simon stood where he was and let his breathing settle. His forearms were wrong. He had felt the feedback the moment the lightning had partially landed, the discharge going somewhere it should not have gone, through the path of least resistance rather than the path he had intended. The sensation had been specific. A branching burn, shallow, running up from both wrists. He had kept moving. He could feel the pattern now, cooling, the particular map of where the current had traveled.

  He turned his forearms up and looked.

  The hollow was quiet around them.

  * * *

  Highmark Registry sat heavy and functional at the intersection of two of the city's main working streets. The ironwork was Forge Hall. The proportions were Sword Hall. The people moving through it were Ba'ag mostly, broad and unhurried, the ambient weight of a population that did not yield to foot traffic without a reason.

  The patrol walked in. They stated their business. The officer at the desk took the proof of completion without ceremony, logged it without looking up, stamped the record.

  "Pack is down," Simon said.

  "Logged," the officer said.

  That was all.

  They walked back out into the city's air. Coal smoke and worked metal and the flat mineral smell that lived underneath both.

  * * *

  He was on the street outside the Registry building.

  Young. Male. He had been standing at the edge of the foot traffic and had not been moving with it. That was the first thing Simon noticed. The city moved in shift rhythms, purposeful and dense, and he was not part of the rhythm. He was watching the patrol come out.

  Slight build. Held himself close. Not cowering. The particular stillness of someone who had learned to take up less space than they had available.

  Something in the shape of him was familiar. Not the face. Simon did not have the face. He had the outline. The proportion of shoulder to height. The way the weight sat. He had seen it before, briefly, at the edge of the transit street two nights ago, already moving away when Simon had other things to read.

  He looked at the patrol. He did not approach immediately. He stood with whatever he had been carrying and sorted through it, and then he came forward.

  "Can you help me," he said. Not quite a question.

  Sylt came up beside Simon. Her voice was quiet, meant for him. "Stomen," she said. "A hybrid of beast and human bloodline."

  Simon looked at him properly then. Fine, short fur at the jaw and the back of the hands, gray-brown and close. The eyes. The pupils were vertical, narrowed in the street's light to a fine line. Feline, his mind supplied, and if the underlying structure followed the same pattern, the eyes were built for conditions where this city's mana-light did not reach.

  He was visibly exhausted. Not the exhaustion of a long day. Something deeper. The kind that had been accumulating for longer than one night.

  "Come with us," Simon said.

  * * *

  The Cinder House put the smell of coal smoke into everything it touched. The common room ran full at this bell, shift workers overlapping at the tables, the noise of two rotations trading places. The patrol found the table at the back, away from the overlap, away from the window.

  The server brought food without being asked. Dense flatbread. A bowl of something rendered slow over several bells, dark and savory. A pot of bitter tea that was not quite what Vyrhold called tea but was hot.

  They put a bowl in front of the boy.

  He looked at it for a moment. Then he ate. He ate the way someone eats when they have not eaten in a long time and have learned to be careful about it anyway. Small careful movements. Not savoring. Managing.

  They waited.

  He finished most of the bowl before he spoke. When he did, he addressed the table rather than any of them specifically.

  "Six of them," he said. "Sword Hall colors. We were running." A pause. "My sister and me. We were running and they found us."

  Nobody spoke. He continued.

  "I tried." He said it without defensiveness. A fact about what had happened. "Two of them took her. The other four came after me when I broke for help."

  Sylt had set down her cup. Her ambient read was running at a level Simon could not sense but recognized from the quality of her stillness.

  The boy's face did something. The particular tightening around the eyes and jaw of someone who has reached for tears and found nothing there. Not composure. Not control. Something emptier than both. He had already used what he had. What remained was the shape of wanting to cry without the means to do it.

  The bowl sat in front of him. He did not look at it.

  Simon let the quiet run for a moment. Then: "Why didn't you say something that night."

  The boy looked up at him. His pupils were adjusted to the room's light now, narrowed to a fine vertical line.

  "You were shaped like them," he said. Meekly. But he said it.

  The table held the words.

  Simon looked at him for a moment. Then he nodded, once, and looked away.

  * * *

  They fed him more. They put a second bowl in front of him and he did not refuse it. He ate steadily. The color came back into him slowly, the way color comes back into something that had gone a long way toward empty.

  When it was clear he was not going to stay awake much longer, Simon stood.

  "My room," he said.

  Sylt looked at the boy. She looked at Simon. She opened her mouth.

  "There's no need to ask, Sylt," Thrynn said.

  Leya nodded.

  They brought him upstairs.

  * * *

  When they came back down the common room had thinned. The shift overlap was finished. The workers who remained were settled in for the long pull of the evening rotation.

  Thrynn waited until they had sat.

  "Are we sure we can believe him."

  No heat in it. No suspicion that announced itself. The flat direct question of someone who needed the ground solid before she put weight on it.

  "Yes," Sylt said. She did not elaborate. She did not need to.

  "The exhaustion and the hunger are not a lie," Simon said.

  Thrynn looked at both of them. She absorbed the answers. Then she set her hands flat on the table.

  "Good," she said. "I wanted to make sure we were walking into this with our eyes open. The evaluation is in four days. The disciplinary action is already filed. We are not in a position where we can afford to be wrong about what we're committing to."

  A beat.

  "Now that I know we're right," she said, "we're not leaving that boy without his sister."

  Nobody disagreed.

  * * *

  Lukas was at the Registry Hall when the patrol arrived. Not at a desk. Standing in the corridor outside the main floor with a document in his hand that he was reading without appearing to read it. He looked up when they came in.

  He set the document aside. He waited.

  Simon told him. Brief. The boy, the sister, the six practitioners, the timing.

  Lukas listened. He did not perform surprise.

  When Simon finished, Lukas was quiet for a moment. Looking at nothing specific. Running something.

  "Participate in the evaluation," he said. Then his eyes moved to Leya. They stayed there.

  "You read spaces, don't you."

  Not a question.

  Leya held the look. She said nothing.

  Lukas looked at the patrol once, the full sweep. Then he returned to his work.

  They left.

  Outside, the city pressed at them. The shift noise. The smoke columns. The pistons steady in the earth below the street.

  Simon walked. He did not ask what Lukas had meant. Lukas had the runner's contents before Sword Hall's ink was dry. He had the dispatch order before Registry had finished writing it. He had the shape of what the patrol needed before the patrol had sat with it. None of that was coincidence and none of it was generosity.

  He had a use for them. The use happened to run the same direction they were already going. That was all it was. That was enough.

  * * *

  The two days passed the way days pass in a city that does not stop.

  The boy stayed at the Cinder House. He ate. He slept. He sat sometimes at the back table and said very little, which the Cinder House did not find unusual. It had seen people in worse states than his and had fed them and asked nothing.

  Sylt checked him. She did not make it clinical. She sat across from him, drank the bitter tea, and her hands rested near his on the table at intervals, the read running quiet and low. What she found she did not report to the group. What she found did not change her face.

  Thrynn ran her floor work in the yard behind the inn at first bell each morning. Precise and unhurried. The Cinder House workers who passed through gave her room without being asked.

  Leya walked the streets. She had been walking them since arrival, the spatial read running low and constant, cataloguing what the city held. She walked differently now. Something in how she set her feet. Something in the quality of her attention. Simon had noticed it since the hollow. He did not name it. He filed it.

  Simon ran his forms.

  The first morning he ran them as he always ran them. The sequence. The particular precision of it. Every movement placing him somewhere specific for a specific reason, the pathways built over many turns expressing themselves through the accumulated mornings.

  The second morning he added something.

  It was not a technique. He had no word for what it was. It was an adjustment. A shift in the angle of a turning movement that created, at the apex, a condition he had been feeling toward since the hollow. His hands came around and for a moment, briefly, they crackled.

  Not the full discharge. Not controlled. A thread of it finding the path he had made available and running it before he had finished making it. The sensation was specific and brief and he stayed with the sensation instead of stepping away from it.

  He ran the sequence again.

  Later in the same form, at a different point, he reached for the distortion. The light bending. What had worked partially in the hollow. He felt for where it lived inside the sequence, which angle created the right condition, which movement allowed the application without the movement becoming the application. He found the edge of it. Not reliable. Not repeatable yet. The light at the periphery of his movement shifted slightly and then it was gone.

  He ran the sequence until the shift bell rang below.

  He sat with the forms afterward the way he always sat with them. Breathing settling. The city coming back in through the walls of the room. The pistons steady underneath everything.

  He looked at his forearms.

  The branching marks were still there. Lighter than they had been. The pattern followed the route the current had taken when it went wrong in the hollow, two days ago, the particular map of where the discharge had traveled instead of where he had sent it. They would fade. They had already begun to. But they were present.

  Tomorrow the evaluation would arrive.

  He pulled on his sleeves. He went downstairs. The Cinder House common room was loud and warm and smelled of the dense grain the kitchen ran at this bell for the morning shift.

  The boy was at the back table with a bowl in front of him.

  Simon sat down across from him and ate.
