The Twelve-Sided Shadow

Basalt never lied, but the iron pins kept jumping out of their boreholes.

Cui Donghai drove his eight-pound sledge against the head of the sixth anchor pin, sending a sharp ring across Ridge Four. The iron wedge sat three inches deep in the grey stone, stubbornly refusing to bite. If he failed to seat the full set of eight before the noon whistle blew from the valley camp below, the haul-teams would refuse to winch the heavy quarry tram cables up the eastern face. That meant another day lost to the Confederation's penalty tallies, and Donghai had no interest in paying the supply clerks out of his own wage packet.

He spat stone dust onto the ledge, adjusted his grip on the ash-wood handle, and raised the hammer again.

The sun went out.

It did not vanish behind a rain cloud or fade behind mist. A vast, sharp-edged shadow dropped across the ridge like an iron plate. The heat vanished from Donghai's leather-clad shoulders so fast his sweat went cold against his neck.

He looked up.

High above the Granite Confederation's northern peaks, a dodecahedron hung suspended in the pale sky. Twelve regular pentagonal facets of matte charcoal-bronze caught the midday glare along their razor-thin joints. It had no wings, no exhaust, and no sound. It simply occupied the sky where the clouds ought to be, five miles wide and dropping straight toward the lower gorge.

"Get down!" someone shouted from the lower tram platform. "Clear the line!"

Donghai did not run. There was nowhere on Ridge Four to run to. The cliff dropped two thousand feet into the gorge on his left, and sheer granite rose four hundred feet on his right. Instead, he dropped to one knee, planted his broad boots against the bedding plane of the rock, and gripped the half-driven anchor pin with his gloved left hand.

The twelve-sided titan hit the valley floor.

There was no boom. No roar of crushed stone shook the basin. The massive shape touched the alluvial terraces and came to a dead halt without kicking up a single pebble of dust.

Then the world turned on its ear.

The sensation struck Donghai not as an earthquake, but as a violent, instantaneous pivot in the pit of his stomach. The downward drag that had held his boots to the ledge since dawn snapped ninety degrees to the east.

The vertical cliff wall at his back was no longer a wall; it was the ground beneath him. The horizontal ledge where he had knelt became a sheer, vertical precipice, dropping away into empty eastern air.

Loose gravel from the ledge did not tumble down into the gorge. It hissed across the rock surface like shot, falling horizontally toward the distant eastern horizon.

Donghai's boots slid off the smooth ledge. The sudden sideways pull tore at his shoulders, swinging his body out into the open sky.

His knuckles turned white around the iron head of the unfinished anchor pin. The iron bent under his two hundred pounds of dead weight, screeching as it levered against the basalt collar.

If the anchor pulls, I fall across the sky.

He did not let go of the hammer. Granite Confederation smiths were taught one rule from their first apprenticeship: when the earth fails, the anchor must hold.

Donghai swung his legs up, searching for traction. His boots struck the vertical cliff face—now the floor beneath him—but the stone was slick with morning seepage. He needed a rigid triangular brace. If his body tilted beyond eighty-five degrees relative to the new gravitational plane, the shear would peel his fingers off the iron.

He wedged his right boot heel into a natural quartz seam, forced his knee to lock, and hauled his torso perpendicular to the stone face. He brought the eight-pound sledge around in a tight, brutal arc, driving the flat steel hammerhead into the anchor pin's collar at a clean ninety-degree strike.

The iron bit four inches deeper into the fissure. The pin held.

A sharp, chime-like vibration rang through the iron handle, vibrating directly into the bones of his forearm.

A translucent pane of pale gold geometry flashed into the air three inches before his eyes, sharp as cut glass.

The violent drag on his arms cut out instantly.

Donghai hung from the pin, but he was no longer hanging. The invisible pressure that wanted to fling him across three leagues of open sky subsided into a steady, manageable weight pressing firmly into the bottoms of his boots. The vertical cliff face felt as solid and level underfoot as the flagged floor of his workshop.

He let out a slow, ragged breath, blowing grey grit from his mustache.

His brass water canteen, attached by a leather thong to his belt, hung straight out into the empty air, pointing east like a rigid bronze pointer. He reached down and prodded the flask with a thumb. It stayed completely horizontal, obeying the wild gravity of the valley below while his boots stayed anchored to the local stone.

"Stupid thing," Donghai muttered, tightening the thong so it stopped rattling against his hip.

Donghai tested his stance, easing his weight back half an inch. A faint yellow wireframe grid projected across the stone around his feet. The moment his left heel shifted three degrees off-center, a crimson flicker crawled along the edge of the display and his stomach lurched with sudden vertigo.

He planted his heel firmly back onto the centerline. The crimson warning vanished, replaced by steady gold.

"Strict," Donghai said to the empty air. "Worse than the master guild-examiner."

A deep, dry crack split the mountain above him.

Donghai turned his head carefully, keeping his shoulders aligned with the glowing gold grid. Half a mile up Ridge Four, a massive slab of grey granite—the entire upper shoulder of the peak—was separating along a clean, mirror-smooth plane.

There were no jagged boulders, no dust plumes, and no tumbling debris. The rock parted with the precision of a hot wire slicing through wax. The top half of the mountain simply lifted off its roots and began sliding sideways toward the east, gliding horizontally through the sky like a raft upon calm water.

Behind the departing mountain face, the sheared interior of the peak stood exposed to the sunlight.

Carved straight into the living core of the bedrock was a colossal flight of black basalt stairs. Each step measured ten yards wide, perfectly square, and cut at a ninety-degree angle to the natural earth—built not for climbing upward toward the sky, but for walking comfortably sideways across the horizon.

Donghai gripped his sledge, locked his boots to the glowing grid, and looked at the road opening horizontally into the blue.
