The fifth shadow matched Devika's next breath.
Its bare shoulders rose when hers did. When she exhaled, the headless shape sank and took one step closer to Jiang.
"It is following whoever watches him," Aylin said.
Devika changed her breathing, and the shadow copied her.
Nerea lowered the hooded lamp. Four living silhouettes shortened across the stair wall. The fifth grew longer, feeding from a seam beneath the next step rather than any body or tool.
"Keep moving," she said. "The chamber is below us. I need room for the rod."
Jiang's feet found each step through the open sling. Devika and Aylin carried enough weight to preserve his shoulder, but stone still scraped his claws and told him where the stair turned.
Behind them, Matthews held the return line. "Four moving. Fifth between Devika and the wall."
Lucia answered from the upper lamp. "I can close on your pull."
The headless shape raised one arm.
Devika looked at Jiang's injured side. Its hand copied the motion and reached toward his silver-ringed mark.
She forced her gaze forward. "It uses care as a route."
"Care still gets to exist," Aylin said.
Green light drew a narrow edge between Devika's shadow and Jiang. The fifth hand crossed it and lost two fingers, yet its arm kept reaching.
The stair opened into a round stone chamber.
One sealed door stood opposite them, dark wood bound by strips of dull silver. The black core thread passed beneath it. Every copper strike and seed-cake smell came from the other side.
Nerea entered first. She set the lamp on the floor with its hood facing the wall and unwrapped the sight rod's aperture.
Dark silver moved across the chamber.
Aylin's shadow carried the branching trace under her collar. Devika's carried a faint rhythm at the throat. Nerea's cast a scarred hand around the rod. Jiang's low outline held beak, missing tail edge, and two uneven feet.
The fifth silhouette showed none of those living changes.
It borrowed each living change instead.
Devika breathed, and a throat appeared. Aylin glanced at Jiang, and one black-tipped ear grew from the empty head. Nerea tightened her scarred hand, and the fifth shape formed fingers around an invisible rod.
"It is assembling from attention," Nerea said.
Jiang wanted to strike before it finished. His feet already pushed against the sling.
Devika felt the movement. "The pressure test taught us what that costs."
He looked at the silver-bound door. Gredudande's true thread remained beyond it. Spending his body on the copy would leave the core stronger and Aylin's trace deeper.
Jiang settled both feet.
The four living shadows entered the chamber. The fifth followed.
Its first breath came from Devika. The second came from Aylin. By the third, Nerea inhaled with them even while fighting the rhythm.
Pressure closed around Jiang's breast.
The chamber pulled every breath toward one shared pace. Aylin's green boundary pulsed with it. Devika's fingers on Jiang's sling tightened to the same count. Even the return line moved against the stair in time.
"It is making one shadow from four," Nerea said.
"Break the lamp?" Matthews called.
Nerea watched the rod. "The core thread would disappear with it. Hold."
The fifth silhouette gained a face from their combined fear. Aylin's eyes, Devika's mouth, Nerea's scar, and Jiang's old human jaw settled together beneath a skin of darkness.
It smiled on their next breath.
Behind Jiang, the return line rasped over stone, a reminder that retreat waited one pull away. Aylin at the sling, Devika guarding his breast, Nerea surrendering the door: they would all leave without blaming him.
That kindness made the route harder to take. Beyond the silver strips, Gredudande held the pattern stolen from four chests while Aylin's trace pulsed beneath her collar. Running would preserve Jiang's breath and teach the creature everything else.
Jiang trusted the three women beside him. Trust felt worse than charging because it required him to remain reachable while they acted.
His beak pressed once against Devika's wrist.
She understood. "One pressure hold. You stay on the floor. I end it if your body loses the choice."
Aylin lowered the rear sling until Jiang's belly met cold stone. "I hold my trace. I leave you still."
Nerea turned the rod toward the fifth shadow. "I find the false rhythm."
Jiang committed to `Pressure Heart I`.
His heartbeat softened into the chamber's pressure.
The next beat waited beyond the shared pace.
Devika's fingers found the slowing pulse and remained steady. Jiang's lungs reduced their work. Warmth withdrew from his feet. Every fast response he wanted became a cost capable of ending the hold.
The four-shadow rhythm reached for him.
It found an empty beat.
The fifth silhouette stumbled.
"Hold that broken rhythm," Nerea said.
Aylin and Devika kept breathing. Jiang's heart chose another living interval, shaped by the flexible dive response rather than the chamber's demand. The counterfeit body jerked between their shadows and failed to predict him.
Nerea swept the sight rod across its chest.
Inside the headless shape, dark silver exposed four stolen breathing lines tied around a black center. No living pulse answered from the center.
"There," she said. "Aylin, below the copied ear."
Aylin drew her own shadow tight against her boots. Green light climbed from heel to shoulder, separating the trace from the face wearing her eye and ear.
The stolen part tore free.
Behind the fifth body, Devika snapped the thermal sheet wide. Crumpled silver caught its borrowed mouth and broke the smile across dozens of bright folds.
"Lucia, close on my pull," Nerea called.
She yanked the return line once.
Above them, the hooded light died.
Nerea's floor lamp remained. Its single beam held the fifth silhouette against the thermal sheet while every upper route vanished.
The false body reached for Jiang.
Without moving, he let its fingers pass over his back, close enough to bend feather tips. Aylin wanted to grab him; he saw the choice in her hands. She turned that movement into a green cut through the black center instead.
Devika held the sheet despite the shape striking her arms. Nerea pinned the exposed center with her padded fork, using tool and light rather than skin.
"Now, Jiang," Aylin said.
He released one low two-voice note through his open beak.
The call required little movement and carried a living variation Gredudande had not predicted. One voice crossed the stolen breathing lines. The second beat against the false center.
Four borrowed rhythms separated.
Devika threw the thermal sheet closed. Aylin sealed its edges with cool essence. Nerea rolled the trapped center away from every living shadow and toward the empty stair wall.
Lucia reopened the upper light.
Brightness struck the sheet from behind. The false fifth shadow flattened between both sources, found no unbroken body to wear, and peeled away from the chamber floor.
It fled beneath the silver-bound door.
Gredudande's black core thread remained visible beyond it.
Jiang felt the pressure hold stretching past usefulness. More sight tempted him; another living choice mattered more.
He ended `Pressure Heart I`.
`[PRESSURE HEART I ENDED: VOLUNTARY | RECOVERY REQUIRED]`
His heart returned with a hard blow against his breastbone. Air filled him too quickly. He coughed, flattened his feet, and failed to lift his belly from the stone.
His right foot kicked once without permission. Cold pins ran up both legs, but the left answered only when he dragged its claws against the floor. The lower door stood within beak reach, and he no longer had enough body to cross it alone.
Devika knelt without moving him. "Conscious?"
Jiang gave one weak tap with his right foot.
"Stay with that. Standing is finished."
Aylin crouched beyond his feathers. "Permission for the sling when we move?"
His second tap granted it for the retreat.
Nerea kept the sight rod trained on the sealed door. "The false shadow crossed back. The core remains deeper."
The silver strips on the door bent outward.
Someone struck the other side with a human shoulder.
"Release the line!" a man's voice shouted.
Matthews flinched above. "That voice is new."
Nerea moved the lamp across the threshold. A real hand appeared beneath the door, bloody at the palm and shaking under its own weight.
The old lock split apart.
A man in black clerical clothes stumbled through, his red sash dark with blood. Gray threaded his hair. One side of his face carried the bruised imprint of a chain.
"Cardinal Martelli?" Nerea said.
He found the penguin on the floor, then the sight rod, and understood enough to be afraid.
"If you followed the voice," he said, "it learned mine before you arrived."
Martelli fell across the threshold.
A dark thread slipped out of his blood and withdrew under the door.
