The new doorway's light was wrong.

  Blue, like the torches, but thinner, stretched over stone that hadn't decided whether it was a corridor or a throat yet. The air had that used feel again, like too many lungs had shared it without anyone cracking a window. Cobblestone picked up where the Witness Chamber floor left off, the lines just a hair off-straight, as if someone had laid them in a hurry and trusted the weight to do the finishing work.

  They stepped through single file, Serh first, then Merrik, then Matas. The ash-figure in the front row watched them go, its hollows empty, and then the chamber fell out of sight behind his shoulder.

  The mailbox flag pulsed in the corner of his vision.

  Four-count.

  [Glance the Fall] rode in on the backbeat.

  The world split.

  In one version, they took three more steps into the new corridor. The slab door behind them stayed exactly where it was: open, patient, unbothered. In the other, it slammed shut with enough force to shear granite, catching Merrik mid-stride and shearing off his heel at the boot. Stone shards sprayed forward, one catching Serh along the cheek in a neat, lethal line.

  Pain lanced through Matas's bad eye, up behind his ear, locking his jaw.

  "Move!" he snapped before his better sense could argue.

  His hand hit the back of Merrik's harness. He yanked him forward hard enough that Merrik swore, stumbled, and crashed into Serh. She staggered, grabbed a stone with one hand to keep from going down, and they all lurched three, four steps deeper into the new space.

  The door behind them came down like a verdict.

  Stone slammed stone. Air punched the back of Matas's neck. Chips and dust sprayed past where Merrik's shoulder had been a heartbeat ago. One shard caught him along the upper arm; it wasn't deep, but it left a line of blood the length of Matas's hand.

  Merrik hissed between his teeth. "What in—"

  The flag flickered again.

  Omen-Touched (Stage 1): Glance the Fall triggered under acute threat.

  Probability Debt: increased.

  Matas swallowed against bile and the needle of pain behind his eye.

  "Door decided it was tired," he said. "You okay?"

  Merrik flexed his fingers experimentally, then rolled his shoulder. "Stings. Had worse from the training ring."

  Serh's gaze went past him to the now-sealed slab. No gap. No light. Just an outline in the stone that might as well have always been there.

  "No going back," she said. "Good. I hate pretending that's an option."

  Matas didn't.

  The corridor ahead of them widened by half again and then resolved into something halfway between hallway and gallery. Benches had been carved directly out of the walls, low stone thrones with their backs sunk into the rock. On each one, a gray shape sat fused into place, half-statue, half-ash, features eroded to near-blankness.

  They weren't the same as the Witness Chamber's neat rows. These looked like the spillover—people who had come late and been told to sit along the side, out of the way.

  They also weren't empty.

  "Eyes up," Merrik said softly.

  "Eyes are the problem," Matas muttered, but he looked anyway.

  The ash-figures didn't move. Not a tilt. Not a twitch. They just sat where time had put them, shoulders slumped, hands resting on knees or folded in laps.

  The cobbles between them and the far door—another slab, this one narrower—had a different story to tell. Scuff marks. Thin channels in the dust where boots had slid, not walked. Little crescents where metal had scraped stone in a hurry.

  The hairs on Matas's neck lifted.

  "That's a lot of panic for such a quiet hall," he said.

  "Maybe they knew you were coming," Serh said.

  Then something cold and gritty latched around Merrik's ankle.

  He swore and went suddenly sideways, his boot skidding on the stone. For a second it looked like the floor was tipping him into nothing.

  Matas grabbed for the back of Merrik's harness again on instinct. His fingers found leather. Weight jerked against his shoulder—more than he should have held at that angle. The bad eye flared. Brace hit in the same heartbeat, legs locking, boots welded to the cobblestone.

  Pain shot up his thighs like someone had driven anchor spikes into each muscle and twisted. His ribs complained about the sudden load. The world narrowed to Merrik's weight and the thing dragging at his foot.

  "Stone," Merrik grated. "Something's got me."

  Serh's spear swung down. The iron tip bit into the bench to Merrik's right with a crack of stone on stone.

  The figure sitting there hadn't moved.

  Its hand had.

  From the elbow down, ash and grit had sloughed away from the fused body and hardened into a forearm that now stuck out over the path, fingers clamped around Merrik's boot.

  The spearhead pinned it just above the wrist.

  For a heartbeat, everything held in a bad angle of tension: Merrik's line to Matas, the ashen hand to his ankle, Serh's spear haft bowing under the strain.

  Then the hand let go.

  It didn't just fall. It crumbled along the length of the arm, ash sloughing away like old mortar as the spear drove through. What hit the floor did so in three distinct clumps—fingers, palm, a shard of forearm. They broke up further on impact, scattering in a gray splash across the cobbles.

  Matas let Brace go before his quads decided to do it for him. The after-shake ran all the way from knees to teeth. Merrik staggered sideways, caught himself on the opposite wall, and sucked in a breath.

  "Everyone accounted for?" he asked.

  "Boot's going to smell like a fireplace," he said a second later. "Otherwise, fine."

  "That's generous," Matas said.

  The ash on the floor twitched.

  Not a breeze. Not the settling you get when dust decides which way is down. It crawled.

  Little rivulets of gray drew together, sliding along the stone in thin fingers toward the nearest bench. They gathered at its base, climbed the plinth in a slow, deliberate smear, and worked their way back into the fused shape's leg.

  Another hand tore free from a different statue three benches down.

  "Don't let them touch your feet," Serh said, voice low and flat. "They don't seem to care about anything higher."

  The mailbox flag pulsed.

  Hostile manifestation: Witness fragment.

  Vector: Omen.

  Behavioral focus: destabilize footing.

  "You had to ask," Matas muttered.

  The corridor erupted into motion.

  Hands pushed themselves out of benches and plinths, wrists flexing as if shrugging off centuries of dust. Some came straight, fingers reaching for ankles. Others scuttled sideways on their knuckles like blind spiders, searching for seams in boots and gaps between cobbles.

  Stolen content alert: this content belongs on Royal Road. Report any occurrences.

  His eye tried to be helpful. For half a breath, the floor became nothing but paths, every hand's potential line drawn in ghost-white over reality. The pain that came with it felt like someone was scraping a chisel around the inside of his skull.

  He did what Merrik had told him back in the lower throat: said what he saw before it killed them.

  "Center line's worst," Matas snapped. "They're going for our weight, not our throats. Keep to the sides—bench edges are less loaded."

  Serh didn't argue. She pivoted to her left, putting her back almost against the carved stone, and started working the spear like a broom handle. Not stabbing. Sweeping. Every time a hand got close, she knocked it sideways, into another reaching limb or against the wall where it could only flail.

  "They don't like joints," she said a breath later. "Break the wrist, they have to crawl to find their knuckles again."

  "Comforting," Matas said.

  One of the ash-hands went for his right boot from behind. The itch got there first, like a nail dragging along the line of his Achilles. He stamped backward on reflex.

  Heel met grit. Something snapped underfoot. Ash smeared, then started dragging itself toward the nearest bench again.

  "Don't get cocky," Merrik said, voice tight. His spear haft took two hands at once, slamming them together and then grinding them against the wall. "These aren't full bodies. They don't have blood to lose, and they don't care if you knock bits off."

  Another hand latched around Matas's left calf, just above the boot top, where leather turned to cloth and then skin.

  Cold grit bit down hard enough that he yelped.

  Instinct pulled his leg away. The hand tried to come with it. The bench didn't. For a split second, he felt the weird give of something that was both anchored and trying to be mobile.

  Fine.

  Two could play that game.

  He dropped his weight backward and to the side, letting the grip on his calf help him pivot. As he turned, he drove his heel into the stone at the base of the bench.

  Not a full Weighted Strike—he didn't have the space or time—but enough intent and angle that the system decided to count it.

  Pain flared through his ankle and up into the old break in his wrist as the strike echoed along bone. The stone under his boot answered with a crack.

  The plinth's front edge sheared off in a neat, rectangular chunk. It fell onto the floor at an angle, smashing two crawling hands to powder under its weight. The one on his calf lost purchase as the bench shifted. He kicked it hard.

  Ash exploded off his leg and scattered across the floor.

  "Better," Serh said. "Use the stone, not just your edges."

  Matas would have given her a thumbs-up, but three more hands were already swarming toward his boots.

  It didn't take long to realize they weren't going to win this by trying to knock every piece away. For every hand they broke, the fragments hauled themselves back toward a bench somewhere. Even when they crushed them to powder, the powder flowed.

  "We need a place they can't climb back from," Matas panted. "A recess. Low spot. Somewhere the stone eats them instead of the other way around."

  "Up ahead," Merrik said between grunts. "Right side. There's a drainage cut."

  Of course there was.

  It was a shallow trough in the floor where water—and now ash—liked to settle. Hands already crawling that way had more trouble climbing back up the lip; ash slid, lost cohesion, and had to gather itself all over again.

  "Drive them there," Matas said.

  They adjusted.

  Merrik took point on that flank, boots shoving, spear sweeping every grasping limb toward the trough. Serh mirrored on the other side, guiding strays inward whenever they lunged for her or Matas. He stayed half a step back, stamping down anything that got clever and tried to go around.

  Brace fired twice more before they were done. Once when three hands got his ankles at once and tried to roll him onto his back, once when Merrik's boot skidded on scattered ash and Matas had to take his whole weight again for two heartbeats.

  By the time the last of the grasping limbs went skidding into the drainage and dissolved into a slow, reluctant flow of gray sludge, his thighs felt like someone had been beating them with hammers. Rope burns of grit and abrasion marked both calves where rough ash had chewed through cloth.

  Merrik bent, hands on his knees, breathing hard. His right knee had a smear of darkening blood where stone had cut through his trousers; not deep, but messy. Serh's left side of her chest was already blooming purple under the leather where one of the arms had managed a lucky hook with more weight behind it than it had any right to.

  The benches watched, as indifferent as ever.

  The mailbox flag pulsed.

  Hostile manifestation: Witness fragments contained.

  Behavioral data: stance control logged.

  "Nothing about passing," Matas said. "Just that it watched."

  "Watching is what it does," Serh said. She prodded the nearest bench-figure once, hard, with her spear. It didn't react. "Room two will be worse."

  "Good," Merrik said. "Means we've still got growing to do before it decides we're not worth the stone."

  They moved on.

  The corridor beyond the benches kinked left, then right, the turns tight enough that they had to go single file again. The air changed as they walked: drier, hotter, with a faint chemical taste at the back of Matas's throat, like the time a propane heater had gone bad in a closed garage.

  His boots started to pick up grit of a different sort. Not ash. Something finer. A dust that clung and dragged, like ground glass.

  They came out into the snakes' room without realizing that's what it was until they were already in it.

  At first glance, it was just another carved-out bulge in the mountain. Low ceiling, maybe a foot above Merrik's head at its highest point. Walls close enough that if Matas spread his arms, he could almost touch both at once. No benches this time. No ash-figures.

  Just floor.

  Cobblestone had given up somewhere back in the corridor. Here, the ground was one continuous slab, smooth enough that his roofer brain immediately distrusted it.

  It wasn't flat. Not really. Not once he looked twice.

  Shallow grooves wound their way across the stone, cut into its surface like dried riverbeds. They twisted, looped, crossed one another in a lazy tangle that set his teeth on edge. Some were barely deeper than his fingernail; others you could have run your thumb down and felt the edges.

  From the right angle, with the bad eye trying to help, they looked like exactly what they were.

  Tracks.

  Serh's lips pressed thin. "I don't like this," she said.

  "Me either," Matas said. "Lines shouldn't look like they're waiting to move."

  The Omen in his head agreed.

  The flag pulsed.

  The grooves lit up.

  Not literally—yet. For a heartbeat, they just predicted it. His vision doubled again, the world splitting into now and almost-now. In the now, the channels were just dry cuts in the stone, catching the light from the one blue torch set high in the far wall. In the almost, they glowed a bright, ugly white-blue, heat shimmering up from them in ropes. Lines of fire rose from the floor and struck at knees and ankles, not teeth-first but like whips.

  His calf muscles clenched in anticipation. Pain carved a vertical track through his eye socket.

  "Don't go any farther," Matas ground out.

  Merrik froze mid-step. His boot hung just above the nearest groove.

  "What now?"

  "Grooves," Matas said. "If they light, they'll go for our legs. All of them. At once."

  He eased back from the cut as delicately as if it had been the edge of a roof with nothing underneath it. His boot came down in a patch of untouched stone. Nothing happened.

  For now.

  "Can you tell which ones are safe?" Serh asked.

  "No," Matas said. "Only which ones want to kill us first."

  "That narrows it down," she said dryly.

  The room didn't give them time to think of a better answer.

  A faint hiss started up under their boots, soft as a kettle just before it breaks. The air thickened with heat, rising in thin threads from the grooves. Somewhere deeper in the stone, something answered with a muffled, hungry crackle.

  "Back," Merrik said.

  They tried.

  The slab behind them had ideas of its own.

  There was no warning this time. No world-split preview. No generous second path where the door stayed open.

  The stone in the archway ground and then slammed shut so hard the floor jumped. Hot air belched around them from the impact.

  A tiny, tired line slipped across the edge of Matas's vision.

  Egress: disabled until trial resolution.

  External support: locked.

  "Of course," Matas said. "Wouldn't want us getting help if we trip over our own feet."

  "We won't," Serh said. "We'll trip over theirs."

  Flame hit the channels.

  It didn't burst all at once. It crawled.

  A thin, blue-white thread of fire licked along a single groove near the far wall, picking up speed as it went. The hiss grew louder. A second line lit along their left, then a third under Merrik's paused boot. They ran in opposite directions, following the curls and loops of cut stone, joining, splitting, crossing each other like a nest of kindling catching in slow motion.

  "Up," Merrik said. "Higher stone if you see it."

  There wasn't much. The floor was designed for walking, not climbing. A few raised ridges where the channels had left islands of untouched rock, no bigger than a man's footprint. They each picked one and stepped on, balancing on the literal high ground.

  The grooves between them burned brighter.

  Flame peeled free of the stone.

  The first one to lift had the shape of a spear thrown from the floor: a straight column of fire, maybe waist-high, narrow enough that Matas could have hugged it if he'd been suicidal. It twisted once, then bent in the middle, the top curving toward Merrik's leg.

  Merrik jerked back. The flame snapped at where his knee had been, missing by inches.

  A second line near Matas's left foot did the same thing, bending, coiling. By the time it struck up, it had a head: a thicker flare at the end, pointed and flickering, with two hollows of darker blue where eyes might have been on something that cared about eyes.

  "Snakes," Matas said.

  "Torches," Serh corrected. "Snakes have more sense than to live in their own fuel."

  It struck.

  Matas hopped sideways onto another tiny island of stone. The flame-snake hit the spot his boot had occupied a half-second earlier. The heat from its passing still seared his calf through cloth, sharp enough to raise a blister.

  He yelped.

  The snake hissed.

  Not like fire. Like pressure. Air was shoved violently aside, a sound more felt than heard.

  The groove it had come from burned brighter for a second, then dimmed. The flame flowed back toward the point where it had risen, then kept going, tracing the cut deeper into the room.

  All around them, more of them were rising. Some were only knee-high. Others towered up to shoulder level, coiling and uncoiling like they were testing the ceiling.

  The flag flickered.

  Hostile manifestation: Witness fragments (serpentine).

  Vector: Omen.

  Behavioral focus: destabilize footing.

  "Noted," Matas said through clenched teeth.

  "Stop talking to it," Serh said. "Talk to us. Where do they break?"

  His eye tried to oblige.

  For a heartbeat, each flame-snake carried a faint, gray line along its length, from floor to head. Some lines were smooth, unbroken well past where a man would stand. Others had faint stress marks: tight little knots of darker stone under the groove, hairline fractures in the channel walls, tiny imperfections that couldn't handle repeated heating.

  "Joints in the cuts," Matas said. "Where the stone's already tired. Hit them there, and the flame stutters."

  "How?" Merrik asked, already moving.

  "Stone on stone," Matas said. "We don't have water."

  The snakes hissed, brightening on six surrounding heads that rose and died as quickly as reaching flames. Each snake head snapped its jaws at us before dying, like they'd heard the plan and were taking offense.
