No one remembered what for. The older soot sprites whispered it was for a creature that had stopped coming. Kamaji, who now needed two pairs of glasses to thread his herb pouches, said nothing at all.
“So,” he said, “the Lantern Eater finally has a face.”
Lin answered. “A former guest. A river spirit that got filled with junk—bicycles, concrete, broken wishes. The Old Master tried to clean it, but it swallowed three workers and turned bitter. Now it lives in the attic. It eats light. That’s why we don’t fill the twilight lanterns. They’re its lure.”
“What’s the Lantern Eater?”
Kai opened his empty lantern. “I don’t have light. But I have an echo. The last time someone said my name out loud, it was a girl on a train. She said, ‘Kai, don’t look back.’ I didn’t. But I remember the sound. You can have that.”
The bathhouse had a new rule: never fill the twilight lanterns.
“I’m looking for the boiler room,” he said.
He climbed alone. The attic was a graveyard of forgotten holidays—cracked masks, torn kimonos, a carousel horse missing its pole. In the center sat a shape the size of a small hill: mud and reeds and rusted chain, with two pale fish-eyes staring sideways. It had no mouth, but it hummed.
