The Ashen Wastes did not kill you quickly.
That was the first lesson, passed down in the shorthand of people who had stopped needing to explain it. The Wastes were patient. They worked through the soles of your boots and into the tendons of your feet, through the rope calluses on your palms and into the small bones beneath. They worked through the filter cloth you pressed to your mouth on heavy vent days, settling into the wet tissue of your lungs in fine grey particles that never fully left. The Wastes did not take you in a single dramatic moment. They collected you in increments, a slow tax levied on every hour spent breathing their air and bleeding into their rock.
Jace had been paying that tax for four years.
He pressed himself flat against the canyon wall of the Tartarus Ravine, boots wedged into a crack in the scorched rock, and let his burning forearms rest for thirty seconds before the next climb. Below him, the 7-C section of the south wall dropped away into haze and heat. A vent fifty yards down exhaled a rolling column of sulphurous gas that turned amber and rust at its edges in the failing light. The smell reached him even at this height — sharp and chemical, coating the back of his throat with something that tasted like burnt copper. He adjusted the filter cloth over his nose and mouth and looked up.
Forty feet of sheer face above him, and then the flat broken ground of the upper Wastes. Forty feet was nothing. He had climbed harder faces in worse conditions with a full satchel banging against his hip. The problem was that his satchel held three cores when he needed eight, the sun was dropping toward the smog line, and Overseer Dreck ran the quota board at the settlement gate with the particular enthusiasm of a man who enjoyed delivering verdicts.
He'd cleared yesterday's numbers at the board that morning. Dreck had looked at the tally sheet, looked at Jace, made a mark without comment. Cleared. The family two rows ahead of him had not cleared. The woman had stood very still at the weigh-table while Dreck read the number, and when he told her the household ration was suspended pending compliance, she had turned and walked away without speaking, because there was nothing to say that Dreck did not already know and did not care about. Jace had watched her go. He had thought about it for approximately the time it took to collect his gear and walk to the ravine, and then he had stopped thinking about it because thinking about it did not change the number on the tally sheet.
Three cores. Today's shift. He needed five more before the light gave out or he'd be standing at that same weigh-table tomorrow morning watching Dreck make a different kind of mark.
Move.
He found a handhold, tested it, pulled. The rope harness bit into his shoulders as his weight shifted. His boots scraped for purchase, found it, and he climbed — the same sequence of movements he had performed so many thousands of times that his body executed them without instruction from his conscious mind. Grip, pull, find, push. The rock here on the south wall was different from the north face where most Scrappers worked — denser, darker, with a glassy quality where ancient heat had fused the layers together. Good for stability. Less good for cores, which tended to form in the looser sections where the Aether had room to crystallize. But the north face had been picked over by four hundred Scrappers working in rotation for years. The south wall of 7-C was largely unexplored. The vent proximity was worse here, and the rock's reputation for instability kept people to the familiar ground.
Jace's grandmother had warned him about the fresh subsidence near the upper ledge. Maren's boy had reported it. He worked below that line, methodical, striking and listening and moving — the rhythm as familiar as his own heartbeat. An hour of nothing.
He was considering moving to the adjacent section when he felt it.
Not a sound. Not a glow. A vibration.
It moved through the rock face and into the iron shaft of his prybar and up through his palms with a regularity that did not belong to stone. Rock vibrated in response to impact, to the pressure of gas vents, to the settling of its own weight. He knew those vibrations the way he knew weather — by feel, without needing to name them. This was different. This was rhythmic in a way that felt deliberate.
Thump. Pause. Thump. Pause.
Curiosity was not a survival trait in the ravines. The standing rule was simple: if it glows, it's worth money. If it hums, it's dangerous. Leave it alone. Jace pressed his bare palm flat against the rock face anyway and held his breath.
There it was again. A pulse, moving through the stone with the patience of something that had been doing it for a very long time and had no particular reason to stop. Warm, in a way that had nothing to do with the ambient heat of the canyon. A warmth that seemed directed. Like heat from a body rather than heat from a surface.
He found the fault line by feel — a hairline crack that ran diagonally for about two feet before disappearing into denser rock. He worked his prybar into it carefully, not forcing, applying steady pressure and letting the rock decide when to give. His grandmother's voice in the back of his mind: the rock talks. You just have to know the language. That was Hudson's line originally, passed through the household the way most useful things were — somebody said it once and it stayed because it was true.
The rock gave with a sound like an exhaled breath. A soft exhalation of trapped air and dust that made him turn his face away and wait for the cloud to settle. When he looked back, he had opened a hollow in the rock face roughly the size of a large crate. Perfectly smooth inside. Perfectly round in a way that no natural cavity ever was.
Sitting in the centre of it was an egg.
That was the only word for it, even though every practical instinct he had was suggesting alternatives — geode, crystal formation, mineral deposit — because those were things that made sense in a ravine, and an egg did not. It was roughly the size of a melon, covered in overlapping scales of a dark metallic material that caught his lamplight and gave back almost nothing. The scales ran in precise rows from base to apex with the regularity that living things produced and geology did not. Rough. Interlocking. Like tarnished iron.
And it was warm. He could feel it from six inches away — not the ambient heat of stored sunlight but something that came from within, steady and even and insistent.
Jace did not touch it immediately. He crouched on his ledge in the dark with the lamp throwing his shadow up the rock face behind him and looked at the egg in its hollow and thought about what it meant.
He thought about Dreck at the weigh-table. He thought about three cores when he needed eight. He thought about the family two rows ahead of him that morning and the woman walking away without speaking.
He reached out and touched the egg.
The jolt went up his arm and into the centre of his chest like a fist closing around something that had been open his entire life. Not a shock — not electricity, not pain. A feeling of profound, desperate hunger that was not his own. The scales rippled under his fingers, warm and alive, and beneath the hunger there was something else entirely — a presence. The unmistakable impression of something aware, something that had been waiting, something that in the moment of contact oriented toward him with a focus so complete it felt like standing in a beam of light.
Then the cliffside shuddered.
The sound came from below — a deep grinding crack followed by a rising mechanical shriek he felt in his back teeth before he heard it with his ears. A Scourge Crawler breaching the upper lip of a vent fifty yards down, its segmented body unfolding from the rock like something that had been compressed and was now releasing. Mandibles spread wide, each one the length of a man. Its sensory cluster — the pale organs at the base of its skull — oriented directly at the satchel-weight warmth against Jace's ribs.
It felt the egg. It was already climbing.
Jace shoved the egg into his satchel, grabbed his climbing rope, and hauled himself up the ravine as fast as his burning muscles would allow. The Crawler scaled the wall behind him with a speed that was wrong for its size, acid dripping from its maw, sizzling where it hit the rock inches from his heels. He did not look down. He scrambled over the canyon edge, rolled onto the flat dusty ground of the upper Wastes, and ran.
He did not stop until he was through the settlement perimeter, past the outer wall of corrugated steel and canvas, through the labyrinth of residential rows, and at the far edge of Ashford where nobody went because nobody had reason to. His private shack — the abandoned structure near the boundary where the settlement ward met the open Wastes. Close enough to the ravine that vent activity discouraged visitors. Far enough from the main paths to be untrafficked. He had found it three years ago, shortly after they pulled him to work, and he had told nobody it existed. Not Hudson. Not his grandmother. Not his mother.
He collapsed onto the floor and unclamped his satchel with hands that were still shaking.
The egg had changed. The iron-like scales were shedding on the outside, turning to ash, flaking away from a surface underneath that was darker and smoother and radiating heat through the canvas like a coal.
Jace sat on the floor of his shack and watched the ash fall from the shell in the lamplight, and the warmth of the egg pulsed against his palms, and outside the wind worked on the corrugated walls the way it always did, and Aethelgard hung overhead like a ceiling blotting out half the sky, and he understood without being able to name it that today was not the same as yesterday and that tomorrow would not be the same as today.
