The First Measure Academy had become a pale line behind the convoy before the midday halt.
Two wagons followed the province road through low fields and old quarry country. Vhar sat beside the team stores with both swords sealed across his back. Nyra rode opposite him with Thronebreak laid across her knees, its wrapped head turned away from the others.
Reth watched the ruts instead of the horizon.
Sera noticed before anyone else. "Has the road done something personal to you?"
"Not yet." Reth pointed his hooked stave toward a shallow print beyond the wagon wheel. "The supply cart passed before last night's rain, but those boots came through after the mud began drying."
Kavos leaned over the side. "Could be boundary workers."
"Could be, though they went toward the quarry and left no returning line." Reth sat back as the driver called for them to move. "One track is a reason to look again, not a reason to invent the person wearing it."
Vhar finished the last of his bread. "That sounds less exciting than declaring sabotage."
"It also keeps me from accusing the cook when we find out he wanted stone salt."
The wagons rolled on beneath lowering sunlight. Old extraction cuts appeared beside the road, first as shallow scars and later as dark shelves descending behind weathered sheds. Long before they reached the camp, the draft beasts began turning their ears toward sounds beneath the ground.
The entry yard stood between two systems of markers. Academy posts were painted white and red. Wildblood boundary stakes carried black iron hooks beneath their red heads, each hook facing away from the managed habitat.
An Academy observer met the convoy with a ledger tied across his chest. Beside him, a Wildblood contract worker wore stone-dust leathers and carried a forked probe polished by years of use.
The observer counted five candidates, one supervisor, and both drivers. "You camp on the upper rim and descend at first light, while the lower cuts stay closed tonight."
The contract worker did not look at the ledger. His attention remained on the draft beasts. "They smell something below the south shelf, so keep them inside the yard until I check the boundary."
Reth climbed down before the team packs were unloaded. At the first hooked stake, he stopped so abruptly that Sera nearly walked into him.
"This one moved."
The black hook faced the camp instead of the habitat. A ring of pale earth showed where the stake should have stood twelve paces east, while damp soil remained packed beneath its new position.
The Wildblood worker crouched without touching it. His forked probe entered the old hole, met stone, and came back carrying a translucent strand no thicker than thread.
"Jaw-root filament," he said. "Dead at this distance, but it belongs on the other side of the line. A Quarrymaw feels warm bodies through these when the strands reach connected stone."
Nyra lowered Thronebreak from her shoulder. "Could the beast have dragged the stake?"
"Not out cleanly, filled the first hole, and turned the warning hook around." He pointed to a flat-edged compression in the soil. "A hand packed this."
Vhar opened the field-meter case and held the instrument above the moved stake. The needle twitched right, eased back, and repeated the same movement three breaths later.
Nyra rested two fingers against Thronebreak's shaft. "The stone answers before the needle finishes moving."
The worker glanced at the wrapped spear and then at her handling seal. "Do not drive that into the ground unless you want every connected filament to feel the impact."
"I won't." She shifted the spear clear of the stone. "Does that rhythm belong to the Quarrymaw?"
"No living animal repeats so cleanly."
Kavos had moved to the rim rail. He waved them over without raising his voice. A black cable emerged from a trench beneath the south descent and ended under the weathered rail. Its copper core had been cut flat. Fresh binding cloth, darkened with lamp oil, lay beneath it.
The supervisor crouched beside him. "That line should terminate at the old collector house."
"It still might," Kavos said, "but somebody opened it here after the rain."
The wind crossed the quarry and struck a loose warning plate.
CLANG!
The echo traveled down the southern wall. Far below, dozens of gray-backed scavengers burst from warm cracks and ran north through the drainage cut. None paused to feed. Two abandoned beetle nests lay ripped open behind them, and a fresh groove crossed the dust where something broad had dragged an armored shoulder against stone.
The Wildblood worker used his forked probe to lift the edge of the groove without entering it. Packed gray hide had polished one side, while four deep claw holes marked where the animal had turned its weight toward the south shelf.
"Healthy adult," he said. "The broad shoulder print and those claws show enough stone control to redirect its body without sliding, so if it reaches open ground, do not mistake low height for low mass."
Sera looked at her hammer, then down at the mineral shoulder mark. "Will this break the armor?"
"Not from the front, because the jaw plates and shoulders carry the quarry stone they grew against. Strike an anchor, an exposed filament knot, a hinge, or the softer body behind the foreleg, since you survive Tier III by taking the habitat away before you trade strength with the body."
Kavos studied the narrow punctures left by old arrows in a nearby post. "Do the filaments bleed enough for me to see them from the upper ledge?"
"They turn dark when cut, so hook them against stone instead of shooting into empty air because a loose arrow may carry the strand back toward you."
Nyra listened without moving the spear. The worker had answered hammer, bow, and body placement according to what each candidate actually carried. When he reached Thronebreak, he pointed toward the jaw groove.
"A long spear can deny the head room to turn, but only if your rear grip has somewhere to go. That shelf will steal length from you."
"I can shorten the line," Nyra said. "I cannot make the people behind me disappear."
"Protect the problem you cannot move."
Sera stared after the fleeing animals. "Those are the scavengers from the lesson."
"Yeah," the contract worker said. "They know the difference between hunting and being hunted."
Reth walked the boundary without crossing it. He found three pale scratches descending from the moved stake toward the western fissures, each carrying more translucent filament. The strands entered a seam in the stone and disappeared toward the lower extraction shelf.
Vhar followed the cable's visible path with his eyes. It crossed that same seam.
"The machine cadence and the sensory strands share the rock," he said. "If the collector pulls, the beast feels it."
The worker gave him a sharp look. "That is what the ground says, but it does not tell us whether whoever cut the cable understood the beast or only got lucky."
The supervisor took the evidence container from Vhar's pack. Using the brass key attached to its lid, Vhar lifted the binding cloth without touching it and sealed the fabric inside. Reth marked both stake holes with white cord, while Kavos drew the exposed cable and filament scars onto the camp map.
Sera remained between them and the rim, one hand on her hammer. "We are not taking the south descent now."
"No," the supervisor said. "We can close the trial, or we can use the west shelf after Wildblood confirms it stays outside the deep feeding line."
Kavos looked toward the upper shooting ledge. "The west shelf gives me height, but the drainage cut runs below it."
"The scavengers have already abandoned that cut," Nyra said. "Which means anything returning through it will not be small."
Reth spread the map across a wagon crate. "The west shelf costs us an hour, but it has three anchor points and an inner wall. If the boundary is wrong there too, we turn around before the first descent."
The five of them studied the route. Nobody mentioned the score until the supervisor asked whether they wanted the closure entered immediately.
Sera tapped the sample shelf on the map. "I still want the field certificate, but not enough to walk through a marker somebody moved for us."
Kavos nodded. "We use the west shelf, and I take the high angle only after Reth checks the ladder."
Nyra looked at Vhar. "You have both swords, but there will be no room to draw if we bunch against the wall."
"They stay sealed unless the lane opens, because my hands will be faster than cutting through one of you by mistake."
Reth drew the west route in charcoal. "Alright, we keep the retreat line on the inner wall, and nobody crosses a filament without calling it."
The supervisor recorded their choice while the Wildblood worker added his contract mark beside the moved boundary. The site remained open only along the inspected western approach; the south descent closed under both authorities.
Closing even one descent had a human cost. Two quarry carts waiting beyond the yard would lose their morning stone, and the contract worker sent one driver back before darkness so no labor crew arrived beneath a false marker. The second driver stayed to carry evidence or injured candidates if the western route failed.
"People will complain about the lost shift," the worker said while tying the closure notice to the gate. "Let them complain; a cart can return tomorrow, whereas a family cannot send the same person twice."
Sera watched the first wagon turn toward the road. "That should be written over more trial gates."
"It should be written over more pay offices." He tightened the knot and left the loose end long enough for the morning crew to see it in poor light.
Camp rose before the last light left the rim. Sera drove the shelter wedges, Reth fixed the retreat line to the first western anchor, and Kavos rejected the rotten upper ladder after testing one rung. Nyra placed Thronebreak within reach beneath the shelter roof and checked the wax thread around its head.
Vhar set the field meter between the bedrolls. Its needle rested farther right than it had on the road, although the false rhythm had stopped.
Below them, the drainage cut remained empty. No scavenger returned for the split beetle nests.
The team had preserved the moved stake, the cut cable, the filament, the fresh oil, and the route decision before darkness took the ground.
Whatever happened at first light would not be allowed to pretend the quarry had been ordinary when they arrived.
