The cold from the arch had not shifted in close to a minute.
He pushed off the block face one shoulder at a time, weight carrying forward, the boot sole going down in a controlled heel-draw along the corridor stone. Both walls returned the scrape before he'd finished the step. Six seconds of nothing from the south. He sent the second step north and kept the jaw locked on the grip leather, each exhale going out in a near-soundless thread between his teeth.

The fourth door frame arrived under his right hand a dozen steps in, one cell past the three from the lantern pass, the face-plate oxide-rough at the rivets. Fifth frame. The mortar joints between them fed their alternating texture into his bare, wire-shredded palms, each boot scrape running south behind him and coming back diminished before the next step made a new one.
The cold moved again on his thirteenth step. The mineral warmth pulled back from the corridor floor ahead in one long recession, no wind behind it, no source in the stone's geometry, its necrotic edge deeper than anything the bog had reached. It arrived at his shins without announcing itself. He shortened the draws to what the fractured rib would allow and pushed the pace north regardless, because whatever tracked behind him had no opinion about what his rib thought.

[ DISTANCE: CLOSING ]
The sixth door frame arrived with its face-plate gone: raw block edge, open space, the door itself hanging outward into the corridor at a steep list with the lower hinge pulled clean from the mortar and the cross-bar lock bent outward and driven into the wall face from the inside. He went through the gap one shoulder first, his coat snagging the hanging door and shoving it further into the cell's dark, the iron giving a single flat scrape against the floor as he cleared the threshold.
[ CELL: OPEN ]
[ INTERIOR: NO DATA ]
NO DATA. ENTERING ANYWAY.
Four feet wide, six deep, the ceiling dropping to head height inside the entrance. His boot found raised flagstones on the first step, the floor buckled in long arched cracks from the bog weight above, and he ran his hand along the left wall and found the rack before his shin found anything else worth noting.
It had come off its wall mounting and gone across the floor in a collapsed mass of forged iron bars and rusted spiked rods from the rack's working face. The frame ran from the right wall to within eighteen inches of the left, the spiked rods angled outward across the gap in an irregular tangle. Past the rack's near edge, fitted stone sat at thirty inches: a second passage at an offset angle to the main corridor, acoustically separated from the cell doors and the close-cut run.
The necrotic cold cleared the cell threshold as he went down onto his stomach on the buckled floor.
He took the dagger out of his teeth and sheathed it first; nothing about that gap was going to be kind to a blade in his mouth. He unhooked the scabbard and pushed it through ahead of him by the pommel, then fed himself into the gap headfirst, boot-toes on the raised stone behind him. The first spike caught the coat at the shoulder blade, the rusted point dragging through saturated wool before the cloth gave with a low, grinding tear. A second spike found the coat's lower hem and pulled a long strip free from the seam. Then the main rack bar settled across his chest, its weight finding the fractured rib in a focused press that climbed through the collar bone and held at its peak for the rest of the traverse. The bar's position and his were a disagreement he couldn't resolve without going forward.

He came through the rack's far edge in a forward pitch and went down onto the offset passage floor, the drop short enough that nothing new broke. He hooked the sword back onto his belt.

His shirt was gone from mid-back downward, the coat's long tear having pulled the linen with it through the second spike, and the passage's deep-earth warmth reached the raw skin at the temperature of something that hadn't met surface cold in two hundred years. Small involuntary contractions ran through his trunk, his muscles doing their own accounting now that the thing they'd been bracing against was behind two feet of collapsed iron and angled stone.
The passage ran about forty feet before the stone changed under his boots.
He cracked the lantern shutter. The beam found the passage end twenty-five feet north: a rough-cut arch, three feet wider on each side than the passage, and beyond the threshold a spatial nothing that the beam ran into without returning. Not the dark of corridor stone, not the sealed black of the ossuary. Something with dimensions the beam couldn't read. He went forward on the fractured rib's terms, one half-step at a time, and stopped at the arch's lip.

He widened the shutter to full, and the cavern opened.
The sphere occupied the center of it. Obsidian, or a material that had taken on all its qualities over long years in the sealed dark: a surface that caught the lantern's orange at its nearest curve in a faint smear of color, then absorbed the rest without returning it, the far hemisphere lost to the cavern's dark. Thirty feet across, at minimum. The upper surface curved toward a ceiling the beam couldn't find. The lower curve dropped away below the equator into a dark the cavern walls simply continued into, descending past the lantern's reach without bottoming out. Four chains ran from the sphere's equator to anchor bolts driven into the cavern walls: massive iron links, corroded to grey-black oxide at every face, the iron at each anchor showing stress fractures in the oxide, short diverging lines running from the bolt heads into the fitted stone. Architect plasteel bolts, countersunk at angles calculated once and never revisited, and the chain links nearest each anchor were the worst, two centuries of load and sealed damp consuming the iron from the outside in.

STRONGLY RECOMMEND: NOT TOUCHING THE CHAINS. STRONGLY RECOMMEND ALSO: NOT STANDING WHERE YOU ARE ABOUT TO STAND.
A walkway ran from the arch threshold to the sphere's near face: four feet of iron plate on support runners, forty feet of it spanning open air over the drop. The plate's outer edges had warped away from the runners in places where the iron had flexed for two hundred years without correction. At mid-span the worst warp had opened a gap between the plate's edge and the runner below. He angled the lantern beam down through it, and the beam went into the drop and kept going without finding anything.
His right boot came down on the plate first. The walkway responded: a slow flexion running outward from the boot's contact point to the wall anchors at both ends, the bolt at the arch's left side shedding a thin curl of stone dust from the mortar around its head. The dust drifted across the lantern beam in a slow sideways fall into the dark. The chain at the sphere's nearest anchor took the load change and groaned. A low, metal-dense note traveled the full oxidized length and arrived at the equator as a faint ring, then carried out across the cavern and came back from all four stone walls at different intervals. The echoes built for several seconds. The last thinned and settled. He set his left boot on the plate while that last echo was still running.

NOTE: THAT GAP IS WIDER THAN IT LOOKS. WE MEASURED. BOTH FEET ON THE PLATE. WE HAVE LOGGED THIS DECISION. WE HAVE CONCERNS.
Open air on both sides of the plate's outer edges, the drop running to no floor the lantern could reach. He ran the beam north along the walkway's center line, and at the sphere's near face, where the equatorial seam ran across the visible curve, a recessed panel sat flush with the obsidian in a square cut: an inset plasteel handle, oxidized to grey-black, the seam channel sealed with something dense and dark from long compression. Forty feet of flexing iron plate between him and it, over a drop with no floor.
The chain groaned again, longer this time, working through the full oxidized mass of the links in a sustained, building vibration the cavern returned from all four walls. The walkway carried the whole sequence up through both boot soles, the warp gap at mid-span opening and closing in the shudder, stone dust falling again in a thin, continuous thread from the arch bolt into the dark.
[ CHAIN: GROANING - 7 SECONDS ]
THE SPHERE HAS A DOOR. THE CHAIN JUST GROANED FOR 7 SECONDS. BOTH REMAIN TRUE. STRONGLY RECOMMEND EVENTUALLY DOING SOMETHING ABOUT ONE OF THEM.
The seam, the panel, the plasteel handle: all Architect work, all designed for access, all of it built to require a man to stand on a forty-foot walkway of warped iron over a bottomless drop on chains actively shedding mortar from their anchor bolts. The original engineers had decided this was a reasonable set of working conditions and built the arrangement to last indefinitely. It had, except for the parts currently failing.
The walkway took his full attention across forty feet. He kept the center line, lantern shutter narrow, each boot landing with deliberate weight. The warp gap at mid-span opened a three-finger spread under his left heel: the plate flexed, the chain groaned at the near anchor, stone dust fell from the arch bolt in a thread. He was four steps past it when the groan faded.
The sphere's near face arrived at his outstretched hand. Cold, the curve running away from his palm in both directions. The recessed panel sat flush at chest height, its seam packed dense with settled particulate. He jammed the prybar's thin end into the seam and worked it along the lower edge in short passes, cracking the compression seal apart in sections, each releasing with a short adhesive pop. The plasteel handle turned under his palm when he pulled it.
A low internal click conducted through the sphere's full mass and out into the equatorial chains at once. The whole suspended structure ran one resonant note before the door swung inward.

STRONGLY RECOMMEND: NOT BREATHING THE FIRST EXHALE. THE FIRST EXHALE IS VERY OLD.
He turned his face sideways and held it turned until the sealed-air release dissipated: warm, dense, carrying centuries of closed stone and old iron with something else threading through both, sweet and dry, clinging when he drew his first breath inside.
Curved obsidian walls on all faces, the flat stone floor set at the equatorial level. Carved channels ran from the ceiling toward the floor in a close grid, with etched sigils cut at each junction. Blood had dried in those cuts and set, turning each carved line the color of old wood.
At the center: the iron maiden.
