That night, she dreamed of a loom. Not her grandmother’s modern one, but an ancient, upright loom made of bone and bamboo. A woman with Oba-chan’s young face sat weaving. Her fingers moved not with thread but with light. And she was singing — a language Saya had never heard, yet somehow understood.

“Before the first chapter,” the woman sang, “there was a thread. The thread became a story. The story became a grandmother. And the grandmother… forgot she was once the thread.”

Inside lay not letters or photographs, but a single handscroll, brittle as dried leaves. She unrolled it slowly. The calligraphy was elegant but strange — half-finished sentences, crossed-out words, and in the margins, sketches: a mountain with two peaks, a crescent moon split in half, a child holding a spool of thread.

Outside, the sun rose over the two-peaked mountain. Saya smiled. She had found the first thread.
