The stink hit them fifty paces before the ridge—damp slate, crushed cedar, and the hot, sour stink of friction-heated iron.
Red smoke from the signal flare hung low in the pine canopy. Beneath it, the mouth of the Old Watch-Trench looked like a broken throat torn into the hillside. The upper timber framing was gone, swallowed by thirty feet of dark, sliding clay.
From somewhere deep inside came a wet metallic screech, then a faint, muffled shout for air.
Field Master Kael pulled up at the edge of the slip, leather boots sinking two inches into mud. His hand reached reflexively for his signal horn.
James cracked his right eye open.
A red-hot needle drove straight into his jaw. The 90Hz molar hum slammed through his skull—a violent, blinding wave of noise. Water channels seeping through slate. Mud weight pushing down. Rot in the cedar. Four distinct heartbeats trapped under the main crossbeam.
Too much. His vision blurred into a smeared grid of failure lines.
"East wall," James gasped, his hand flying to his temple, teeth creaking. "The east wall is about to—"
He stopped. Clamped his jaw shut until a drop of dark blood prickled his lip. He forced his eye down to a slit, filtering out the slop.
"No," James grunted, voice stripped flat. "East wall's fake. West brace holds it. That goes... ceiling drops."
Drake didn't ask questions. He dropped into the trench entry, heels planting with a dull thunk into the clay. His left arm hung dead at his side, but his hips squared, his good shoulder locking into the angle of the earth.
"Watch the lip," Drake said. "Ground's moving."
They dropped below the timber frame into the damp dark.
The air smelled of crushed limestone and turned mud. Fifteen feet down, two junior surveyors were pinned behind a bowed ironwood support. Above them, the main ceiling beam bowed downward like a drawn bow, groaning under forty tons of wet slate.
Drake stepped under the beam, taking the load path onto his back.
Then his dead shoulder slipped.
The mud beneath his heel gave way three inches. The ceiling dropped with a sickening, grinding shriek—screeech.
"Drake!" Xander called.
Before the timber could snap, Luna dropped flat on her hands into the black slush.
She didn't summon green leaves or wild vines. Her breath hit the wet earth in a steady, deliberate rhythm. Beneath the bowed beam, a thick, pale pillar of dense ironwood erupted straight from the granite shelf below. It shoved upward with a dry, heavy thump, wedging itself under the fracture line just long enough for Drake to reset his heel and lock his frame back into the stone.
A temporary pillar. Living wood carrying slate.
Xander crouched near the wall gap, his eyes closed, hand loose in his pocket. A faint, cool breeze drafted past his knuckles, pulled through the cracks in the stone.
"Listen," Xander said.
Kael froze.
"Hear that?" Xander asked.
"Nothing," Kael said.
"Exactly," Xander muttered. "Should be groaning. Load moved."
Kara moved past them, sleeves pushed back, blue frost tracks mapping her veins straight up to her collarbone.
Near the surveyor's legs, a heavy iron ring bracket was glowing dull cherry-red, expanding under sheer pressure, seconds from snapping.
"Don't touch it!" the trapped surveyor screamed. "It's about to—"
Kara didn't raise her hands or chant. She reached out, hovered her bare palms two inches from the metal, and breathed out.
A quiet plume of white frost drifted from her mouth.
The glowing red iron lost its color in a single, shivering instant. The heat vanished, sucked straight into Kara's palms. The bracket dull-greyed, contracted, and locked frozen into the wood with a sharp clack.
Kara pulled her hands back, tucking them violently under her armpits as her body shuddered. Blue frost bloomed dark under her fingernails. Teeth chattering, she looked down at the surveyor.
"Was," she whispered.
Ten minutes later, the four surveyors were out on the bank, wrapped in wool coats.
The trench mouth remained quiet, braced by ironwood, frozen metal, and an anchored shelf.
Down the trail, forty pairs of heavy boots stomped through the mist.
Upper campus cadets rounded the bend, carrying heavy brass lifting-arrays and active fire-lances. At their head was Professor Vane, his junior tutor spectacles perched on his nose, a leather case of surveying slates tucked under his arm.
Vane pulled up ten paces back, his stride stuttering.
No screaming. No blood. No raging fire.
"Master Kael!" Vane called out, his voice thin, his hand tightening on his slates. "We brought the—"
He stopped.
His eyes swept over the scene. He looked at the pale ironwood pillar bracing the main beam. He looked at Kara, huddled in her coat, shivering quietly. He looked at Xander, who was casually wiping dark clay off his fingers.
Finally, his gaze landed on James—sitting on the mud bank, jaw set, right eye dead grey and still as marble.
Vane's mouth opened, then closed. In his side pocket, his hand tightened so hard his white stick of fresh chalk snapped with a faint pop.
"...Where is the structural breach?" Vane asked, his voice losing its momentum.
Kael didn't look up from binding a cadet's ankle. He gestured toward the quiet trench with a dirty glove.
"Under control," Kael said.
Vane adjusted his spectacles, his posture stiffening as the arithmetic in his head completely failed. "Who braced the shaft?"
Kael stood up, wiping clay off his palm.
"Unassigned."
