The train pulled away from Sea Charts Town Station.
Beads of moisture lingered on the windowpane, refusing to dry even when wiped. The humidity of Sea Charts Town had seeped into the very air inside the carriage.
Koyoi pressed his finger against the glass. A droplet transferred to his skin, forming a thin film over his fingertip. It had the same texture as the water in Starfall Town—water that had dissolved names into itself.
He had journeyed through three towns now.
In Shimozato, names were frozen. If you touched them, frost would bloom against your skin, leaving shards of ice beneath your fingernails.
In Starfall Town, names were half-melted. When he dipped his hands into the wells, the lukewarm water slipped like silk through the gaps between his fingers.
And in Sea Charts Town, names were buried in the mud. Even after the sludge he scooped up had dried, it left dark streaks following the fine lines on the backs of his hands.
Three different states, all preserved in the same record.
"Kuon," Koyoi said, his drawstring pouch still resting in his lap. "That record you read in the fissure at the Heart of Shadow… tell me a little more."
Kuon sat with his catalog closed upon his knees. The light emanating from his prosthetic eye was faint. The strain of pushing his output to the limit at the center of the Shadow still weighed on him.
"I could only read fragments. But I found the way." Kuon opened his eyes slightly. "Deep within the Scripture Repository, there lies a primordial record—the record of the one who first ordered names to be frozen. The three wells are the keys to that repository."
"And where’s the entrance?" Asahi asked.
"Churyo," Kuon replied.
Koyoi looked up.
Churyo. They had been there before. The station with the pale, ghostly lights.
"The entrance only reveals itself to those who have journeyed through the three towns and witnessed the three states. That was the condition."
"Did you know that from the start?" Asahi’s voice dropped low.
"I didn't know it. I traveled to confirm it. Even for me, it was nothing more than a hypothesis." Kuon traced the cover of his catalog with his palm. The gray decay was spreading from the corners of the duplicate; he could feel the deterioration even through his touch.
Koyoi looked at his own hands.
Beneath the nails of his right hand, the frost of Shimozato still clung, white and stubborn. On the tips of his left, the water of Starfall Town remained as a thin, undrying film. And across the backs of both hands, the mud from Sea Charts Town traced the wrinkles of his skin in dry, brown lines.
It was exactly as Yaé’s prescription had said: The medicine is already in the patient’s hands.
"They’re all still here," he whispered. "All three traces, on my hands."
"Yeah," Kuon said. "Your hands are the key."
The scenery outside the window began to shift. The humidity vanished, replaced by air that was cold and biting.
The train entered the Heart of Shadow.
It was their fourth time passing through.
The gray rushed toward them, but this time, it didn't feel as overwhelming as before. The memory of the "true colors" he had glimpsed the second time, and the "fissure" he had found the third, made the wall of gray feel thinner, more fragile.
There were more fissures now than before.
Slender cracks ran everywhere across the gray walls, and through them, color was leaking out. Even after the train cleared the Heart of Shadow, the cracks did not vanish.
The gray failed to recover completely. The scars of the ruptures remained, turning the world outside the window into a mottled patchwork of gray and vibrant hues.
"…It isn’t closing," Kuon muttered, staring at the window. "The fissures are staying open. The Heart of Shadow can no longer maintain control."
"You mean it’s collapsing," Asahi said.
"It is. The power required to sustain the Bleaching is no longer sufficient."
Inside the pouch on Koyoi’s lap, something pulsed.
A heavy, singular throb. The bead within the droplet—the jewel that held three colors at once—was glowing in resonance with the fissures outside. A faint light leaked through the fabric of the bag.
"This little one feels it, too," Koyoi said. "It’s beating in the same rhythm as the cracks outside."
Kuon looked back and forth between the glowing pouch and the fractured world beyond the window.
"It is the same record. The three states within the bead and the records kept in the three towns… because they share the same root, they are resonating."
The train began to slow.
A pale, bluish light appeared outside. Only around the light did the gray seem particularly thin, as if the glow itself was fighting back against the Bleaching.
It was Churyo Station.
The train came to a halt. Even before the doors opened, the very weight of the air changed. It wasn't humidity, and it wasn't a chill; it was a pressure being pushed out from somewhere much older, much deeper.
Koyoi clutched the pouch to his chest. The bead’s pulse was quickening. The "droplet" knew before any of them that they had reached the place it had been waiting for.
Asahi stood up, his sword's scabbard clattering briefly against the seat.
"Let’s go."
The doors slid open.
The air of Churyo poured into the carriage—heavy, ancient, and silent.
The three of them stepped out onto the platform. The cobblestones beneath their feet rang with a hardness unlike any of the previous three towns.
Koyoi looked down at his hands. Under the dim, ghostly lights, the traces of frost, water, and mud each shimmered with a different, haunting glow.
