The worn-grey chick ran beyond Black-Crown's reach.
Jiang dropped onto his belly before his feet could fail him. One shove from the good foot sent him after the youngster; the slope and wind supplied the rest.
His breast scraped over wind-hardened ice. The right flipper steered. Bound cloth dragged on his left side, pulling him toward every hollow he meant to avoid.
Ahead, the basalt shelf narrowed over the buried salt road.
The chick reached its edge and stopped.
A low adult called from the left.
Another answered from the right.
Both voices carried the soft ending that had drawn the youngster away from Black-Crown. Neither side showed a body. Dark rock broke the shelf into blind corners, and wind had polished every approach clean.
Jiang came off the slope too fast.
He spread his right flipper, dug his beak into snow, and turned. The sling jerked across his shoulder. His body stopped with one foot over a crack and his breast facing the chick.
Black-Crown appeared on the opposite ridge.
The adult had taken higher ice rather than following Jiang. It lowered its head toward the youngster and gave a short warning call.
Ignoring both visible adults, the chick called into the empty shelf. Left and right answered at the same instant.
The two hidden adults shortened the final note by the same amount. They waited through the same breath and repeated together.
Head swinging between the blind corners, the chick tried the left. That voice called again unchanged, even when the youngster sharpened its answer and waited.
Both hidden adults returned the first soft promise.
One step carried the chick right. It lowered its belly, called from a different posture, and received the same two replies. A living parent might have been frightened, angry, or already rushing into view. These voices remained patient because nothing waited behind them.
Jiang stayed still. He had no parent call to offer, and borrowing one more voice would only give the fragment another mouth.
Black-Crown called again from its visible body. The warning was harsher now, aimed at the open crack rather than the chick.
As the youngster stepped backward, both false parents softened their voices. It kept retreating until Jiang's body stood between its tail and the open crack.
Relief barely reached him before black-green light rose through the crack.
A root strand followed the chick's shadow across the ice. It curled around one webbed foot, climbed the grey down on its belly, and tightened without touching flesh.
Jiang drove his breast between the shadow and the light, taking the closing loop around his black outline instead.
Cold bit through feathers already emptied by Frostwake. Jiang pressed lower, pinning the strand against the shelf while the chick stumbled free behind him.
The root pulled toward the crack. Jiang's breast slid a hand's width before his claws found rough ice. He bit down on a ridge and held with beak, foot, and body weight while the bad shoulder shook inside its sling.
Behind him, the chick pecked once at the strand. Jiang barked until it backed away.
Black-Crown struck from above.
Its first peck cracked green ice. The strand twisted under Jiang and threw pain through his ribs. A second blow broke the raised loop but left its buried length pulling at the shelf.
Fractures opened under Black-Crown's feet.
The adult jumped back. A slab near the left false voice dropped far enough to expose darkness beneath it, then caught on the root like a tooth in wire.
"Hold there!" Aylin shouted.
Her damaged voice tore on the second word. She came over the ridge bent low, one hand clamped over her injured arm. Split-Beak and Grey-Throat remained behind her with the trailing birds.
Aylin saw Jiang on the strand, Black-Crown above the crack, and the chick pressed against Jiang's tail.
She reached inside her coat.
The silver splinter lay across her palm, shorter than the width of two fingers. Once it had belonged to a road between worlds. Repeated crossings, rescues, and false shelters had reduced it to a warped sliver with one bright edge.
Aylin turned it over with her thumb. One face still reflected green; the other had gone grey from old burns. Her hand closed around it long enough for the sharp edge to reopen the cut in her palm.
Jiang barked a warning.
Aylin looked at him. "I know what it is."
He struck the ice with his beak and pointed toward the salt road. Her last piece could still matter later. Somewhere beyond the fragment waited Eres, Edric, and every answer she had crossed Earth to find.
"It stops being a road home if I spend people to keep it," she said.
Aylin set the bright edge against the salt-road crack. It bent before it entered. She leaned her weight onto the dull side and pushed until metal touched the buried root.
Silver light ran under the shelf.
The left adult voice broke into three Pale-Cheek calls. The right became Grey-Throat, Edric, and the worn-grey chick layered over one another. Reflections peeled off the basalt and showed the black-green root braided through every footprint behind them.
The splinter burned white in Aylin's fingers.
She held it until the final bright edge vanished. Her empty palm carried a red groove and a dusting of burned silver.
Beneath Jiang, the revealed braid tightened.
Every uphill track fed the shelf. One strand held the dropped slab; another ran under Black-Crown; thinner cords reached back toward Split-Beak and the hungry adults. Cutting beside Jiang would release the slab and leave the rest anchored under living feet.
Aylin followed the braid with her eyes. At the shelf's center she raised her glowing hand, then saw the cord holding Black-Crown's slab. Farther back, another branch passed beneath Grey-Throat's feet.
"One cut drops this side," she said. "The rest keeps every bird behind us."
Jiang shifted his beak toward the saddle knot. Cutting there would catch all the converging tracks, but reaching it now meant abandoning the chick on the shelf.
Aylin gathered green light around her wounded hand.
Jiang pecked the root once, then pointed to the birds standing over its branches.
"I see them," she said.
Her fist closed. Natural Essence cooled against her skin without entering the ice.
The false parents called again, one from either side. Their borrowed voices had separated, but both still promised the chick a body beyond the rock.
The youngster gave a rough answer of its own.
Neither promise changed with it. Each returned the same soft ending it had used before.
The chick turned its back on both voices.
It pressed against Jiang's tail until Black-Crown crossed the safe edge and placed its breast on the other side. Warmth existed between them for the space of one frightened body.
A possessive thought rose in Jiang: keep it here. He hated how quickly rescue had become a claim. The youngster had backed toward a body it could see; tomorrow it might choose another.
Jiang crawled left along the shelf and tapped a slow pair with his beak. He returned to the exposed center, rested until his good foot stopped shaking, then dragged himself right and struck three quicker beats.
Two marked exits led away from the braid.
Jiang stopped tapping and waited.
Black-Crown tested the left route with one foot. Aylin moved to the right and planted her boots where the shelf still held. Neither called the whole group after them.
In the resulting silence, known bodies found one another before routes did. With its older chick tucked close, one adult turned toward Aylin's downhill exit and kept its breast between the youngster and the crack.
Recently fed pairs followed at their own distances. Across the shelf, two empty adults faced Black-Crown and the western ridges. They tested the left route without bringing chicks after them.
Split-Beak waited for Grey-Throat to choose the first step. The chick went right toward Aylin, so its parent covered it from the wind and followed.
The worn-grey youngster left Jiang's tail.
It looked left at Black-Crown, right at Aylin, and downhill toward the changing calls of other chicks. After a long shiver, it moved toward the living voices below.
Black-Crown gave one low call behind it. The youngster paused, answered, and kept going downhill. They remained two strangers who had shared warmth on a dangerous climb.
Jiang stayed beside the shelf as it went.
The revealed braid slid out from under his breast. Black-green cords withdrew from the fractured shelf one by one, leaving ordinary cracks and a slab that settled with a heavy knock.
All of them pulled back toward the saddle.
There the strands tied themselves into a dark knot beneath the shared footprints.
Groups began moving away from it.
Black-Crown's call sounded downhill from the path it had left.
Grey-Throat answered from the western route it had never taken.
From the knot between them, Gredudande called to each group in the voices walking the other way.
