The iron muzzle scraped the bark a second time, working left to right across the grain of the root above his feet, slow and deliberate, the rusted cage holes reading the upper edge of the gap.
It didn't come in. The iron cage over its jaws was the reason. The Inquisition bred its hounds to find and hold, not to take, because a heretic torn apart in a hole couldn't be put to the question. It would work the mouth of the hollow and bay until the man on the other end of its chain caught up, and that man would not be far behind.
Vane lay on his back with the hollow's far wall against his shoulders and the entrance six feet past his feet. The waxed canvas ground-sheet was rolled tight at his belt. Getting it out meant working the frozen leather tie with a seizing grip, pulling board-stiff canvas free in a four-foot-wide space with a root ceiling, then getting it to the entrance without turning around. Fine. He pressed the dagger back into its sheath and went for the roll with his left hand.

[ HOUND: ENTRANCE - PROBING ]
STRONGLY RECOMMEND: FASTER.
The leather tie had gummed with bog residue. He drove his thumbnail under the stiff knot and felt the nail flex. On the second drive, the knot shifted. He got the roll free with his fist. The sheet's leading edge hit his knuckles rigid in its folded shape, the wax locked into every crease during the ditch submersion, as unyielding as cold wax in a cold space. He worked his forearm under the top fold and levered outward, and the canvas came free in a stiff, dragging slide.
Rendered tallow spread through the hollow's sealed air the moment it came clear, old and concentrated, sitting over everything else.
He got the near edge across his chest and shoved it along the floor toward the entrance, both forearms pushing together. One rigid corner caught the root ceiling and another caught between his feet. He worked the second corner free with a short kick, the locked knee delivering the kick two seconds after the command, and pushed the canvas another foot toward the gap.
[ GROUND-SHEET: DEPLOYING ]
[ ENTRANCE: 4 FEET ]
[ HOUND: STILL OUTSIDE ]
FOUR FEET. YES WE ARE COUNTING.
He came up onto his palms and backed toward the entrance in short drives, pushing the canvas ahead. The root ceiling caught his coat at the shoulders with each push and dragged the frozen cloth backward against him. Three drives, then the cold coming through the gap reached the bog floor around his calves in a thin, flat edge from below. The canvas had reached the threshold.
The muzzle went still at the gap's upper edge. The scraping stopped. A long, even pull of breath came through the cage holes, deliberate and unhurried, drawing the new smell down into the hollow.
The tallow.
He kept backing, one more drive off his palms, until his head cleared the low root section and the entrance sat within reach. He braced the near edge against the bark threshold at the gap's lower lip with his left forearm flat across it. The blizzard hit the other side of the canvas at the same moment, slamming the stiff sheet inward in one hard impact.
[ WIND: SEALING LOWER EDGE ]
[ UPPER THIRD: OPEN ]
THAT'S WHERE THE SCENT VENTS. JUST SO YOU KNOW.
The upper edge pulled inward at the gap's crown, the wax-locked fold holding the canvas away from the bark whatever Vane needed it to do. He jammed the upper right corner into the crook where the root forked at the gap's right edge, pressing the heel of his right hand against the canvas until it seated. One corner. He reached across his own torso with his left arm at full extension, the frozen coat seam cracking through the arc, and found the upper left edge by touch. He dragged it toward the root's left side and jammed it into a bark split with the flat of his palm, pressing until it stopped moving.
The blizzard hit the canvas full-face an instant later and pressed it taut across the entrance.
The four corners held in their bark crooks under the wind's full push, the lower edge seated hard against the root lip. The tallow smell came back dense from the canvas face, and the blizzard's roar above reduced to a low vibration traveling through bark and wood rather than air, filling the hollow at a register below sound.

[ SCENT LAYER: FAT/WAX - ACTIVE ]
[ HOUND: STATUS UNKNOWN ]
IT'S UP. THE IRON-WEED SEEP IS STILL HAPPENING BEHIND IT.
The iron muzzle found the lower left corner a moment later, working at the seam between bark and canvas in short, even passes, testing the edge where the wax-locked weave met the root crook, the cage holes pressing steady against the canvas from outside.
His left hand, shifting against the far wall to brace his weight, brushed something that wasn't root or frozen peat.
Stiff, rotted canvas. A leather strap gone brittle with age. A satchel, half-buried in the freezing mud. He wasn't the first prospector to decide this hollow was a good place to hide, and the previous owner had never left.
Beneath the strap, flat against the satchel's back panel, an oilcloth sleeve held something rigid and square. He left it where it was. Below it, a canvas sack clinked like iron when his knuckles pushed past, and under that sat a coil of stiff rope. He left those too.
His bare fingers worked over the rotted canvas in the dark, finding an outer sleeve. Inside it, wrapped in old cloth against rattle, was exactly what a deep-wastes prospector carried to break frozen ground.
[ DEAD DROP: DISCOVERED ]
He slid the dagger back into its sheath. This needed both hands.
[ PRYBAR: ACQUIRED ]
[ HOUND: LOWER CORNER - ACTIVE ]
Three feet of forged iron, the claw end heavier than the shaft, tipping in his grip as he pulled it free in a grinding drag. The claw dropped onto the bog floor with a flat ringing note that the hollow threw back from every bark face at once.
He couldn't lift it. The root ceiling ran flat at back height with no clearance for a swing. He pushed the bar ahead with both forearms flat against the ground, steering the claw toward the canvas's lower left corner where the muzzle kept working, its pressure visible as a short, repeating bow in the face. He brought the blunt end down with his weight behind it.
The frozen earth sent the force back up the shaft into his raw palms before his grip had finished committing, a sharp report through bone, the arm ringing from palm to shoulder. The claw hadn't moved. He reset and struck a second time, the blunt end cracking against the root ceiling and folding its resistance into the strike. A chip of frozen peat broke from the entry point, and the claw settled by no more than the chip was worth.
[ EARTH: FROZEN - FULL DEPTH ]
[ CLAW: UNSEATED ]
[ HOUND: TESTING LOWER EDGE ]
CORRECT. THAT WAS ONE CHIP. THERE ARE MORE. ALLEGEDLY.
Third strike. He kept both forearms rigid through the rebound this time, trapping the force and driving it down instead of bleeding it off. The chip had opened something in the surface grain, and the frozen peat below it shifted character. The claw's angled face drove sideways into the bark of a buried cross-member running beneath the hollow floor, bit in, and held.
He got the canvas's corner fold down over the claw's neck and pulled it taut against the seam. The wax-locked weave resisted the angle with a stiff, cold pressure, then went taut and held the corner flat.
[ PRYBAR: LODGED - ROOT FACE ]
[ CORNER: HELD - PROVISIONAL ]
[ IRON-WEED: SEEPING - CONTINUOUS ]
PROVISIONAL. THE WORD IS DOING REAL WORK.
The muzzle's pressure had shifted from the lower corner to the center. Vane still held the prybar's grip end in both hands, the iron cold against his bare, shredded palms, the claw lodged in the root face at the floor's edge. He wrenched the claw free of the root face, the pinned corner slumping loose behind it, and pulled the shaft back along the hollow floor toward him, where the surface had shown that different character on the third strike.
[ HOUND: CENTER CANVAS - TESTING ]
[ GROUND-SHEET: HOLDING - PROVISIONAL ]
He drove the blunt end down.
The sound that came back was not frozen earth.
It came up the shaft into both wrists before the note had finished running, a high, clean ring at a register frozen peat had no business producing, cracking across the hollow with a clarity that had nothing to do with the low blizzard vibration in the root mass. The blizzard traveled through wood. This traveled through something else, and the bark walls threw it back from every direction at once: bright, hard, going on half a beat past when it should have quit, and then further still.
[ ALERT: METALLIC CONTACT - GROUND ]
THAT'S NOT DIRT.
He held the prybar shaft without moving. The tallow-soaked canvas, the hound's intermittent pressure against its face, the hollow's complete stillness; the ring died in a long, receding note against the bark. His forearms had stopped. The cold worked through the iron into his raw palms at the same patient rate it had been working through everything all night.
Then the floor moved.
Three inches at the hollow's center. A slow, grinding subsidence, the frozen peat crust separating from the substrate along a seam running in a rough arc from the near wall to the mid-floor, the surface dropping away in fragments as the weight below it found a new resting point. One layer pulling away from another, as if something supported for centuries by a structure beneath it had just felt that structure move. He slapped his right palm onto the floor to redistribute his weight.
The bog floor was not there.
The peat crust at the center had dropped, fragments tilting down on their broken edges into the gap below. Where the floor had been, old rust showed at the gap's inner face: dense orange-brown, pitted and fibrous, the iron oxide of metal corroding for an age in a sealed, wet space. The peat fragments had come to rest on a latticed surface, and what showed through the gap was not more earth.
Architect work.

[ GRATE: CORRODED - COMPROMISED ]
[ DEPTH: UNKNOWN ]
WE RECOMMEND NOT PUTTING YOUR WEIGHT ON THAT. WE ALSO RECOMMEND MOVING. THESE DO NOT BOTH APPLY AT ONCE.
The plasteel lattice showed through the fragments in sections: each bar running in a cross-hatch eight inches on center, the surface eaten to rough texture by oxide but the original geometry holding beneath. Two centuries of bog load had sat on top of it. The rust had gone fibrous at the bars' upper faces where the peat packed against them, and where the fragments had pulled entirely clear the plasteel showed grey-black below the oxide, darker and harder than anything the bog had produced. Through the lattice, the dark ran to no visible bottom.
He pulled both arms flat against his chest and lay without moving.
The canvas bowed inward at its center as the hound made another pass, the wax face pressing in a short, repeating rhythm. The prybar lay along the hollow floor at his side, two inches from the gap's outer arc, and the ring from the strike was still working through the root mass, section by section, the blizzard's vibration absorbing what little remained of it.

[ YOU ARE LYING ON TOP OF IT ]
WE CANNOT MAKE THESE NUMBERS ADD UP. WE HAVE TRIED.
Without thinking about it he had dragged the satchel strap over his shoulder and slid the bar through it along his back. The lattice bars groaned once, deep and metallic. Then the floor went in a single cascade: the central bars first, the oxide fracturing along each joint at once, the cross-hatch collapsing inward along its own axes before any single bar could go alone.
The sound ancient plasteel made under full load failure was nothing iron had ever produced: higher, sustained, the note climbing as each bar torqued against an old oxide bond before the bond gave, and it filled the hollow at a register that cut through the blizzard's low conduction and held for half a second with no room in it for anything else.
The floor was gone before the sound had finished ringing. The dark came up from below in one fast swallow, and he was already falling through it.

The root mass overhead withdrew upward in the System's blue and was gone. The shaft walls moved past in the dark at a speed his body hadn't found on its own in some time, cold Architect plasteel close on all sides, smooth enough under the corroded face that his right hand found three seconds of contact before the locked knee kicked and broke the angle, and the wall passed and did not wait.
His left thumb found the cartographer's disc in the coat pocket, the grooves worn near-smooth, the Banker's Weight pressed cold against his sternum, and the shaft walls moved past in one unbroken column of corroded metal with no sign of when they intended to end.
