The sparkdrake weighed almost nothing and still managed to occupy Ren's entire left shoulder as if the bone had been reserved for it.
Sparkdrake was not a Compact breed-name. It was the working word pit crews used for a small Rift-hatched thing with bronze plate, a coal-center eye, and a habit of sneezing live heat. Most sparkdrakes that came over the fence did not live long enough to need a better word. They burned a conduit, took a bolt from a watch rifle, and went into a sample bag if the watch was honest. This one had hatched in Ren's hands. It did not walk. It claimed. Claws hooked into the patched seam of his coverall. The tail wrapped once around his collarbone. The chin parked against his jaw, so that every few steps he received a face full of warm bronze plate and the smell of hot metal after rain.
The link opened the way a comms channel opens when the person on the other end is already talking.
[Warm. High. Mine.]
Not words. Pictures with weight behind them. Up. This human is acceptable scaffolding. Do not set me down or I will bite the soft place.
Ren kept his voice low. The service road was empty except for a distant ore hauler and the wind that never quite left the Rift fence. That wind smelled of cold stone and old ozone. Everyone in Slagfall knew why.
The fence did not mark a property line. It marked a wound.
The Precursors were the civilization that had been here before the Compact, before the pits, before the stacks. They were gone. What they left was ruin, scavenged code, and tears in the fabric of space. The Compact called those tears Rifts. A Rift did not open with warning. It simply was: a bright, wrong seam in the air, or a dark one, and then the seam began to print beasts the way a foundry printed parts. Most tears near a settlement were small. What came through them ran from the size of a chicken to the size of a large dog. The Compact's standing order was close the tear or stabilize it until it stopped printing. Closing took crews, Grade Two and Grade Three charge-stones seated in rift-anchors, and time. Stabilizing took less stone and left a scar in the ground that children were told not to touch.
Slagfall lived beside an old scar. The waste beyond the fence was Rift-scarred because the Precursors' ruin under that ground had never finished dying. Small tears still opened out there. The watch closed what they could. What they could not close in an hour, they pinned with anchors until a specialist arrived.
Far from districts like this, past the last warm settlement and the last regular shuttle lane, lay the Rift Front. The Front could not be closed. Some stretches of it held still for years. Some did not. The Front printed everything from chicken-sized hatchlings to beasts large enough to break a haul-rig by walking past it. Rumor, which the pits treated as a kind of weather report, said that once in a long while a Front-beast died and left behind a crystal that did not belong to any of the five grades. Those stones had no copies. They were not a sixth rank. They were individuals. Ren had never met anyone who had held one. He had met men who claimed a cousin's foreman had seen a crate stamped with a name instead of a grade. That was as close as Slagfall came to the Front.
Cinder—though she did not have the name yet—shifted on his shoulder and sneezed a spark into the wind.
"You hatched beside a coolant tank," Ren said.
[Correct. Excellent dumpster. You found it. Therefore mine.]
"That is not how property works."
The little thing sneezed a spark into his ear. It stung. Then, smug:
[It is now.]
A flicker cut across the bottom of his vision. Not a hallucination. Text. Clean, industrial, the same family of lettering a haul-ticket reader used when it wanted a signature, except no ticket reader had any business living in the wet surface of an eye.
BOND MATRIX: ACTIVE
PARTNER: [UNREGISTERED / RIFT-FORGED / JUVENILE]
DESIGNATION: —
SYNC: 11%
CLASS: —
STATUS: NULL (CONTESTED)
WARNING: SIGNATURE DOES NOT MATCH KNOWN TEMPLATES
Ren stopped walking.
A bond matrix was not a Class. A Class was what the Resonance Key woke in human blood: Caster, Knight, Artificer, Field Medic, the four permitted shapes the Compact knew how to train and tax. A bond matrix was older language. It was precursor architecture, or the Compact's best attempt to read precursor architecture, sitting between two living things and reporting on the join. Licensed companion bonds existed. The Academy issued them. Those bonds came with breed-books, feeding schedules, and a registered designation before the creature left a lab. This overlay had none of that. It had a warning.
When he focused on the text the way he focused on a haul-ticket reader, more lines unfolded.
AVAILABLE FUNCTIONS
— Link-speech (emotional / imagistic)
— Shared proprioception (limited)
— Spark output: 0.4 kJ (uncontrolled)
NOTE: Host Key returned NULL. Secondary architecture detected.
Do you wish to name the bond-partner?
Shared proprioception meant he would feel, in part, where her limbs were, as if a second set of balance-signals had been laid along his own. At eleven percent it would be only a tug, a hint of wing-twitch when there were no wings on his back. Spark output at 0.4 kilojoules was a rude sneeze, not a weapon. A Grade One lamp core stored more than that and spent it slowly. She spent hers in specks of heat that singed foam and ears.
The sparkdrake butted his cheekbone.
[Name. I am not "it." I am magnificent.]
"You are the size of a lunch pail."
[Temporary. Name.]
Ren thought of slag, of the way the egg had flexed under his thumb, of the three claw-marks of light that had crawled across the membrane and then, later, would rise under the skin of his own throat. "Cinder."
The overlay accepted the word as if a form had been filed in a place he could not see.
DESIGNATION LOCKED: CINDER
SYNC: 14%
Three points for a name. The join liked being called something.
Cinder made a sound that was a laugh if a laugh could also be static.
[Acceptable. You may keep your tall name. Ren.]
He started walking again. Home was four stacks down, two flights up, a door that stuck in humid weather. His mother would be off shift in forty minutes. He needed a story that was not: I put my hands on a BIO-CONTAIN crate and now I have a diagnostic overlay in my eye and a Rift-forged juvenile on my collar.
Cinder offered one.
[Tell her I am a heater. I am warm. This is true.]
"You are a spark-spitting lizard with opinions."
[Heater with opinions. Even better.]
The stack smelled of boiled grain and solvent. Mara Calder had the same grease-line across her knuckles that Ren had inherited. She had come off the evening cut with stone-dust still in the creases of her cuffs. She took one look at the bronze thing on his shoulder and did not raise her voice. Pit people did not spend breath on odd animals. They asked the useful question.
"Is it going to eat the wiring?"
"I do not think so," Ren said.
Cinder, without shame, sent through the link a clear picture of chewing a power conduit to find out what the current tasted like. The conduit in the picture was the stack's main line, the one that fed the wall-lamps and the hot plate. Those lamps ran on Grade One cores. A chewed line would drop the whole floor into dark and leave three families blaming the Calders until a tech reseated the contacts.
Ren stepped on that thought. He did not have a manual for stepping on another creature's intent. He only refused it, hard, the way he refused to put a bad shard in his pocket. The overlay flashed.
SYNC SPIKE 14% → 19%
HOST: SUPPRESSION ATTEMPT NOTED
PARTNER: AMUSED
Five points for an argument. The join liked that too, which was not comforting.
Mara washed her hands at the basin, set out two bowls, and then a third saucer of broth because she was not a monster. "Priming?"
"Null." He said it flat, the way a haul-weight was said flat when the number was the number. "They will process the Nulls tomorrow. Secondary scan. Paperwork."
She nodded once. That was the whole conversation the Calders required for disappointment. Then she pointed her spoon at Cinder. "If the Compact asks, it wandered in from the fence. Happens."
It did happen. Small Rift-print beasts came over or under the wire after a tear opened in the waste and the watch was slow with the anchors. Most were hungry, lost, and the wrong shape for a kitchen. A few were useful enough that a block kept them until a Compact inspector made a note. Mara was offering him the oldest story in the stacks: the fence gave it, we did not go looking.
Cinder preened.
[I like her. She understands dumpsters.]
Ren ate. The grain was the same as yesterday. The broth on the saucer vanished in three precise laps and one spark that scorched nothing only because Cinder aimed at the broth and not the table. Mara watched that spark the way she watched a Grade One core that flickered in a lamp housing: not panicked, already measuring whether it would need replacing.
"If it burns a hole in my wall," she said, "you patch it before second shift."
"Yes."
That night Cinder slept against the side of his neck. The second pulse sat under his own and did not fade when he closed his eyes. Shared proprioception arrived as a dream of four wings that would not open and a hunger shaped like a rat. He woke once to the overlay ticking SYNC: 20% and a note that said nothing he could use.
Morning processing for Nulls was held in a prefab clinic that had been a parts depot before the Compact painted a medical sunburst on the door. The waiting room still had bolt-holes in the floor where shelving had stood. Twenty-three youth sat on benches, most of them already wearing the look of people who would be back in the shaft by midweek. A bored tech waited with a scanner heavier than yesterday's drone. The scanner's housing held a seated Grade Two crystal, clean enough that the light in the window ran in a straight line. Grade Two was the Compact's ordinary work-stone: good for tools, sidearms, and clinic gear. It did not forgive a bad seat, but it did not require a witness the way Grade Three did. Ren found himself noticing the seat the way his father had taught him to notice a lamp that was about to die. The pins were tight. The lattice, what little he could see of it, was uncracked. Someone who knew their work had put that stone in.
"Calder. Neck."
The second scan was not a shot. It was a collar of cold light and a hum that made his teeth itch. Cinder, hidden inside his jacket because the sign on the wall read NO ANIMALS, went rigid against his ribs. Through the link came a single tight image: the three claw-marks, then a fist closing around them.
The tech frowned.
Ran it again.
Called a supervisor.
The supervisor was Compact, gray at the temples, tired in the specific way of a person who had seen too many readings that did not fit a form. She looked at the readout. She looked at Ren. She looked at the faint three-mark glow that had risen under the skin at the base of his throat, the same marks that had crawled over the egg beside the coolant tank.
"Null on primary," she said. "Secondary is not null. It is not a listed Class either."
The overlay translated the official language without being asked.
OFFICIAL READ:
ANOMALOUS BOND MATRIX
UNCLASSIFIED COMPANION SIGNATURE
PROVISIONAL STATUS: GRAY-FILE
RECOMMENDATION: OBSERVATION / REMEDIAL INTAKE
DO NOT ASSIGN STANDARD ELITE TRACK
DO NOT RELEASE TO LABOR POOL UNTIL CLEARED
Gray-file meant the Compact had no permitted box and would invent a holding box until a specialist said otherwise. Elite track was the shuttle and the Academy and the stipend. Labor pool was the shaft on Monday. He had been removed from both.
The supervisor pinched the bridge of her nose. "You have something. We do not have a box for it. That means you do not go back down the pit and you do not get a shuttle seat with the golden-eyes. You get a holding berth and a specialist when one can be spared."
"How long?" Ren asked.
"Until someone who understands precursor-bond architecture leaves orbit and looks at you. A week. A month. Do not leave the settlement. Do not let that—" she flicked a glance at the bulge in his jacket, because of course she had seen it "—start a fire in the stacks. If it is a companion, keep the sync under control. Unclassified bonds have a habit of eating their handlers when the percentage jumps too fast."
The warning was not poetry. Licensed bonds rose on a schedule the Academy published. Unregistered Rift-forged bonds did not. Sync was the join's own measure of how much of one nervous system had been loaned to the other. Rise too fast and the loan stopped being a loan.
Cinder's voice in the link was small for the first time.
[I will not eat you. You are my dumpster-finder. Eating is for conduits.]
Ren let out a breath he had not noticed he was holding.
Not a Class. Not a stipend. Not an Academy crest. A gray file, a sparkdrake the size of a lunch pail, and a system that still printed CLASS: — as if it were waiting for him to invent the rest. The Key had found no Caster, no Knight, no Artificer, no Field Medic. The secondary architecture had found Cinder and refused to apologize for the mismatch.
The supervisor stamped a temporary chit and slid it across the counter.
CALDER, REN — GRAY STATUS / BOND OBSERVATION
Travel: settlement only
Next scan: 72 hours
Seventy-two hours was three days of staying inside Slagfall's wire, sleeping under a second pulse, and not letting a sparkdrake negotiate with the stack's main line.
Outside, Cinder climbed back to his shoulder and shook herself the way a cat shakes off rain. The bronze plates clicked. A single spark died on the clinic step. The Grade One strip-lamp over the door flickered in answer, then steadied. Coincidence, or the beginning of a habit. Ren did not know which.
[Seventy-two hours. We will become less small.]
"You are already planning to grow."
[Obviously. Also: there is a rat behind the clinic. I would like to discuss tactics.]
The overlay ticked.
SYNC: 22%
NEW FLAG: SHARED HUNT IMPULSE (SUPPRESSED)
QUEST? — OPTIONAL
[ ] Do not let the specialist arrive before you understand your own matrix
The last line was not Compact language. Compact language did not offer optional work. Precursor code did as it pleased. The matrix, whatever it truly was, had decided he needed a warning dressed as a task: learn the join before a specialist arrived to name it for him, or take it from him.
Ren looked at the chit, at the slag heaps, at the thin line of Academy-shuttle contrail still fading in the upper air. Nineteen woken youth were already beyond that line. He was not. The fence ran the other way, toward waste and old tears and the kind of small printed beasts the watch shot if they came too close to the wire.
Short weakness. Not gone. Only unnamed.
"All right," he told the weight on his shoulder. "Tactics. And you do not chew the stack wiring."
[We will negotiate.]
