Dusk was gathering fast in the hollow as the sun dipped behind the jagged crest of the Spine. That turned the sky from pale amber to a deep, cold violet. The mountain draft swept down through the gorge. That brought the first bite of the evening freeze that made their breath plume white in the twilight.
Ten paces west of the freshly approved eastern pad lay Limeworks Square West.
It was a mirror to its partner. Sixteen paces square, lined up true to the world-size spirit vein, enclosing an open pad of hard-packed yellow calcining clay and crushed limestone rubble. In its southeastern side stood an old three-step loading stone base where quarrymen had once backed their carts to load burning lime powder barrels.
Fellis Dain had already set the water-tube level between the two pads, verifying that the outer edge height of Square West matched Square East within three finger-widths along all four boundaries. Both squares rested upon the exact same massive stone shelf of dolomitic limestone exposed in the drainage gallery eight paces below.
“The shape is flush,” Fellis said. He knelt at the northwestern corner peg to check the side sight line. “Height matches. North posture matches. The two parcels are a natural physical pair.”
Kezra wiped the sweat from her palms onto her woolen coat, stepped across the blue-whipped outer edge cord. Then she took her first pacing stride.
Sixty-four paces around the outer edge: sixteen paces south along the western kerb, sixteen paces east along the gorge rim, sixteen paces north through the neutral buffer, and sixteen paces west along the northern crag wall.
With each step, her boots pressed into the familiar yellow clay. Her body was tired—her shoulder blades carried a dull ache from two hours of heavy mallet work. The chill in the air made her knuckles stiff—but her survey pace remained steady. She locked the outer edge map points into the memory of her rag-paper ledger.
She completed the sixty-fourth pace. Then, the notebook warmed in her sling, inking the western square onto the open spread opposite Circuit Four.
“outer edge confirmed,” Kezra said, turning inward to face the inside matrix. “Now the sixteen nodes.”
She took her four-foot iron sounding rod and the two-pound steel mallet. She stepped to Node One in the northeastern side.
CLINK.
“Node One: yellow clay over compact rubble. Depth eight paces. Sound.”
Fellis chalked the slate.
CLINK.
“Node Two: bedded limestone beneath gravel. Depth eight paces. Sound.”
CLINK.
“Node Three: edge of the loading stone base foundation. Sound.”
She worked steadily across the quarter-width grid. Four paces between nodes, checking the plumb level, driving the rod tip into the packed earth, and striking the brass handle knob with measured, rhythmic force.
By the ninth node, however, the cumulative body toll of forty sound soundings began to exact its price.
The blast waves traveling up the Swedish iron shaft were no longer draining away cleanly through her arm. A sharp, burning ache throbbed in the fleshy base of her thumb. Her fingers began to twitch with reflex tremors whenever she relaxed her grip. A high, faint ringing—like the sound of a distant silver whistle—started up in her right ear, clouding her hearing senses of the deeper bedrock pulse.
At Node Twelve, she struck the handle knob.
CLINK.
The return pulse sounded muddy, blurred by the static buzzing in her own head.
“Node Twelve,” Kezra stammered, swaying slightly on her feet as a wave of lightheaded dizziness washed through her temples. “Node Twelve... I think it’s sound... But the return feels thick—”
A firm hand caught her by the collar of her coat. It pulled the iron rod out of her fingers.
Paxa Sel stepped into the square, her medical bag already open in her hand.
“Halt,” Paxa commanded, her voice brooking no pushback. “Sit down on the stone base. Now.”
“Paxa, the light is failing,” Kezra protested, blinking to clear the grey spots swimming in her vision. “I have only four nodes left—”
“You’ll not strike another blow with numb nerves,” Paxa said sharply. She pushed Kezra down onto the stone steps of the loading stone base. “If your fingers can’t distinguish between a sound void and swollen tendon sheaths, your sounding sheet is a forgery. You’ll sit here for ten minutes while your blood clears.”
Paxa pulled off Kezra’s right glove. The skin around the wrist tunnel was flushed red, warm to the touch, and trembling with micro-spasms.
From her satchel, Paxa drew a small glass vial of packed peppermint oil and bitter pine-resin. She rubbed three drops into the palm of Kezra’s hand with firm, kneading circular strokes. The cold, piercing sting of the bitter pine-resin made Kezra wince. But within thirty seconds the fiery ache in her thumb began to numb and subside.
Next, Paxa uncapped a pigskin canteen of cold water dosed with coarse stone salt and crushed willow bark.
“Drink half of this,” Paxa ordered. “Slow sips. Your nervous system is a salt-current battery. When you strike that iron rod, you discharge electrolytes into the rock. If you don’t replace the salt, your tone check sense shuts down to protect your brain from sense shock.”
Kezra drank the bitter, salty water, resting her head between her knees as Paxa massaged the tight muscles along her forearm.
Beside them, Yseld watched the darkening sky with her hooked staff propped against the stone base. “Ten minutes, Paxa. The stars are already coming out. If we can’t finish the anchors before full darkness, we’ll have to finish by torchlight.”
“Then we’ll finish by torchlight,” Paxa replied calmly, checking Kezra’s pulse with her thumb. “I’ll not allow an untuned map maker to cut anchors.”
For eight minutes, the hollow was silent save for the wind through the brambles. Kezra breathed deeply, opening and closing her hand, feeling the bitter pine-resin soothe the inflamed nerve sheath. The faint ringing in her ear faded away, replaced by the clean, sharp silence of the mountain dusk.
Her vision cleared. Her fingers steadied.
“I’m ready,” Kezra said, looking up at Paxa.
Paxa tested her grip strength, nodding once. “You have four nodes and three anchors. Don’t hurry your strikes.”
Kezra rose from the stone base, took her iron rod, and stepped back to Node Thirteen.
She set the tip, raised the mallet, and struck with clean, centered force.
CLANG.
The return pulse was crystal clear. Pure, unblurred dolomitic limestone ringing back from the eight-pace datum like a struck bell.
“Node Thirteen: sound!” Kezra called out, her voice strong and steady once more.
CLINK.
“Node Fourteen: sound!”
CLINK.
“Node Fifteen: sound!”
CLANG.
At Node Sixteen, set beside the southern boundary kerb, the final sound pulse surged through the rock, joining with the mesh of Square East to form a unified, ringing sound plane across the entire tiered arena.
On the open page of her notebook, the internal grid snapped into place with sharp, black glass shape:
INTERNAL LITHOLOGY Checked: 16/16 NODES SOUND TO 8-PACE DATUM.
“Now the anchors,” Kezra said.
With Fellis holding the horn lantern over the rock, Kezra knelt four paces beyond the northwestern, southwestern, and southeastern corners of Square West.
Her chisel work was swift, clean, and practiced. Three equilateral triangles, three inches on a side, half an inch deep, pointing their sharp apices toward the sharp-angled center of the western pad. She blew the fine white stone dust clear, pressed her bare palm into each pocket in turn. Then she felt the warm ringing link click home in her marrow.
As the third anchor locked, the Bonded Survey Notebook flared with deep, golden warmth in her hands.
Across the right-hand leaf of the centerfold, the formal status slate of Circuit Five inked itself into the rag paper:
Kezra stared at the two completed slates sitting side by side across the open spread.
PARCEL 04: Limeworks East (Approved) and PARCEL 05: Limeworks West (Approved).
Five completed circuits out of forty-four. Five live sites anchored out of eight maximum, leaving three open slots for the long road ahead.
“Circuit Five approved,” Kezra whispered, her voice full of awe. “The pair is complete. Both sixteen-pace squares are live, approved, and paired under the thirty-day walked thread.”
Fellis slammed his palm against the base stone, a wide, triumphant grin lighting his face in the lantern light. “We have our home pair! Two full Plot squares right here on Kilnstep land!”
He turned toward the edge of the pad. There, an old, two-wheeled wooden lime handcart stood resting against the retaining wall.
“Now,” Fellis said, his rigger’s curiosity burning bright in his eyes, “before we trigger the practice exchange, I want to test something I’ve been wondering about since the doorstep swap.”
He walked over to the handcart, grabbed the shafts. Then he rolled the heavy two-wheeled barrow into the center of Square West.
“What are you doing, Fellis?” Kezra asked, closing her inkhorn.
“Testing the cargo limits,” Fellis replied. He reached into his pocket for a length of stout raw, unwhitened hemp rope. “If we’re marching to Saltglass, we’ll have freight carts and baggage barrows. I want to see if tying a cart to a post makes the notebook treat the vehicle as a fixed structure.”
