The silver line cut through Jiang's shadow and waited.
Devika moved first. She slid the wrapped heat away from the line while keeping it beside the shelter wall. "Nobody follows the mysterious floor crack until my patient keeps breathing."
"It is a route," Aylin said.
"Routes are floor cracks with confidence."
Ruth shut the dry side door against the wind. "How do we test it without giving it somebody?"
Father Matthews stared at the shaving balanced on its edge. "We begin with the light. That is how the rod left."
He pointed toward the chapel's side windows. During Monsignor Keane's vigil, late light had crossed the bier from there. Matthews had carried the dark silver rod past the feet, expecting its blessing to end the service.
"The shadow under him moved against the light," Matthews said. "The rod pulled toward it. I dropped the thing before I understood what I had seen."
"Did the shadow touch you?" Ruth asked.
"It reached. The rod came between us."
Aylin's compass hung straight down. "The living thing beneath the dead man used the rod."
Father Matthews looked toward the empty nave. "That sentence is worse than the version I have carried."
Ruth cleared the nearest chairs while Devika remained beside Jiang. The warming-room guests had left through the dry exit before the altar fight, but their cups and folded blankets still marked the tables. Nobody would be invited back into an experiment.
"I need a lamp," Matthews said.
Devika opened her transport kit and passed him a broad examination light. "This came for a penguin, not a haunting. I want it returned."
"I have never lost a medical lamp to Rome."
"Your record with silver rods concerns me."
Jiang's breath stirred flour on the tray. He might have enjoyed the exchange more if a line beneath his body had not been waiting to swallow a shadow.
Matthews placed the lamp where the chapel windows had cast the vigil light. Ruth angled it first at the empty transport crate. Its barred shadow crossed the shaving.
Dark silver dropped flat.
They next used the folded red velvet, one chair leg, and the case that had once held the sight rod. Each shadow passed over the shaving without opening the line.
"Objects fail," Aylin said. "It wants life."
"We have one result repeated," Devika replied. "Use the word fail after you know the test."
Aylin accepted the correction with a tight nod.
Ruth shifted the lamp until the silver curl lay outside Jiang's silhouette. The line beneath him withdrew. When she angled the beam back, his rounded breast and short feet fell across the shaving again.
The shaving lifted onto its edge.
Blue text appeared above the flour.
[SIGHT ROUTE DETECTED]
[ROUTE REQUIRES: ONE LIVING SHADOW]
The System offered no destination and no promise that a passenger would arrive alive.
Around the lamp, every person cast one. Ruth's shadow reached across the abandoned cups. Devika's hands made a pair of dark birds over her open kit. Matthews kept his close to the pew. Aylin's stretched east with the compass.
The panel had turned each living body into the same kind of payment. Jiang hated how quickly a route could make that sound reasonable.
On the flour, Jiang scraped two words: LIVING SHADOW.
Devika read them, then looked at the line under his body. "Your private hallucination has excellent timing."
"You still think he is hallucinating?" Aylin asked.
"I think labels come after evidence. The floor is currently winning."
Father Matthews moved toward the lamp.
Ruth caught his sleeve. "Your shadow stays out. You already gave this thing one bad night."
"I know the first crossing."
"Your value is the memory you carried here," Ruth said. "Keep your body beside me."
Matthews stopped. Fear showed in the hand he tucked beneath his opposite arm. He had come carrying information and old guilt, and Ruth had named the difference before he could confuse them.
Aylin set her compass beside the shaving. A narrow green loop formed around the metal without touching it.
"No Natural Essence enters the road," she said. "I hold the boundary only."
Jiang tapped once. Her wording preserved a limit instead of asking them to trust intention.
Devika counted the rise of Jiang's breast with two fingers resting on her own knee. "Shiver present. Head still up. You get one short test before I end it."
Aylin tilted the compass. The route line followed its eastward needle, sliding from beneath Jiang toward the altar. A gray slit opened in the floor, too narrow for a claw and deep enough to contain moving light.
At its bottom, candles burned upside down.
Father Matthews knelt outside the beam. "Those are not Mercy Street candles."
Their flames leaned in different directions. Some were white and clean. Others smoked beneath bronze lamps Jiang had never seen. Stone arches appeared between them whenever the slit widened, then folded away before he could hold one shape.
Rome existed somewhere inside that depth. So did every wrong place connected to the same road.
"Destination unproven," Devika said.
The copied contact call came through the shaving.
Jiang's feet pressed against the towel. His body heard an emperor penguin beyond the slit, isolated and calling for its group. Penguin Instincts reached under the perfect note and found no offered location, no pause for his answer, and no concern for what followed.
Gredudande had found the road.
Aylin's compass chain tightened around her fist. The bruised ring on her throat darkened as the gray slit bent toward her shadow.
"It already carries my trace," she said. "Use me for the test."
She had honored Jiang's stop beside the shelter. Now she was trying to make that debt payable with herself. Four dead candidates stood behind the offer even if she never named them.
Jiang struck the tray rim, hard enough to scatter flour.
"We need to know where it goes."
He dragged his beak through LIVING SHADOW until the words vanished beneath a white furrow.
No passenger would enter.
Aylin met his gaze. "You refused to let the prisoner claim me. This is my choice."
Jiang pointed his beak toward the black hook creeping from the slit into her shadow. Her offered choice had already attracted Gredudande. Whatever answer she gave now would come with the trace pulling at her throat.
Ruth saw it too. "A choice made after the hook closes is captivity with polite timing. Step away."
The hook crossed Aylin's heel.
Green light jumped along her leg. She tried to lift her foot, but her shadow held flat against the stone while the rest of her moved.
Devika reached for her and stopped before entering the light. "Tell me what contact helps."
"Break the lamp," Aylin said.
Father Matthews raised his hand toward the switch.
Jiang answered with one bark.
Breaking the light would close the route with Aylin's shadow already inside. The last trapped fragment had survived by flattening between surfaces. Gredudande might keep whatever the closing line cut away.
Jiang pushed himself upright.
His supported flipper stayed bound to his side. The good flipper opened for balance, and both feet shook beneath his weight. Devika put one hand near his breast without touching.
"You have three steps before I catch you," she said.
Two steps would reach the line.
The first webbed foot landed across the silver line. The slit pulled wider around his toes, yet its height collapsed toward the floor.
Jiang dragged the second foot beside it and lowered his breast over the shaving.
An emperor penguin's shadow had no long human legs to seize. His rigid body filled the lamp beam in one low block. The road shrank around that shape, losing the height it had used to climb Aylin.
The black hook slid down her calf.
Aylin pulled her foot free and fell backward into Ruth rather than across the route.
Jiang's tired legs folded beneath him.
Devika caught the towel beneath his breast and returned him to the cooler shelter opening. The exertion had quickened his breathing. His shoulder dressing remained closed, but warmth drained through his feet where they had crossed the silver.
"Test over," she said.
Father Matthews killed the lamp only after the shaving lay free of every human shadow.
The deep slit closed. Dark silver remained upright beneath Jiang's low silhouette, tracing an opening no taller than his breast.
From the hair-thin gap, Gredudande called again.
The sound reached for a penguin and found a doorway shaped exactly like one.
