THE MUSIC BEHIND THE WALL

Several months after Wella's Ascension, Hallowmoon Academy was trying, in its slow and stubborn institutional way, to return to normal.

It was not succeeding.

Archchancellor Vermillion had fallen — that was the word the Council settled on, fallen, as if he'd lost his footing on a stair rather than been stripped of his seat and confined beneath the tower he once ruled. In the months since, his private records had been retrieved from hidden panels and false shelves across the Spire, laid out for a small, exhausted committee of scholars to examine.

Students whispered about it in the corridors, in the dining hall, in the cold morning queue: what had truly happened on the summit the night the Veil tore and healed itself, whether a wound-thing had walked through the outer wards unchallenged, whether the new Nightingale had performed the Ascension with a second violin at her shoulder, unlike any Nightingale before her.

Brother Armir had been given access to archives that were once restricted to the Archchancellor's office alone, and the collapse of nineteen years of institutional secrecy had left him dry, precise, and quietly delighted. It was, he told anyone who would listen, the single greatest professional development of his career, and he meant to catalog every dust-choked shelf of it before some future Council found a reason to seal it up again.

Twenty-year-old Petra Vey was one of his student assistants. Privately, she thought the restricted archive smelled less like history than like a building that had spent two decades trying hard to forget things on purpose.

Her starblood was weak — a thin, unremarkable thread of it, nothing that would ever let her lift a violin toward the Sundering and expect it to answer. But she had something the testing pipes had no way to measure: an ear for residual resonance, the traces of old music left behind in the wood of instruments, the stone of rooms, the leather of forgotten ledgers. She could run her fingers along a violin case and hear the last three songs it had ever carried. She could stand in an empty practice hall and know, without being told, that someone had wept there once, mid-scale, and never finished the exercise.

An unglamorous gift, Brother Armir liked to say, and an extremely useful one, which was precisely why he'd hired her.

She was cataloging manuscripts late one evening in the newly opened lower wing, still thick with the smell of old dust and older secrets, when she heard something that should have been impossible.

A woman, singing.

It came from nowhere she could place, low and aching, half-swallowed by stone, a melody she didn't recognize, threaded with a voice that trembled at the edges, the way a voice trembles after singing for a long time. She rose from her desk without deciding to, candle in hand, and followed the sound down a row of shelving until she stood before a section of wall that was entirely solid stone.

She pressed her ear against it.

The singing stopped.

For a single held breath, there was nothing at all. Then, so quietly she felt it more than heard it, a whisper pressed against the far side of the stone, as though someone had leaned their mouth to the exact spot where her ear now rested.

Don't let them close the door.

Petra didn't move for a long time. The candle burned steadily down while she stood with her palm flat against the stone, waiting for the voice to come again, for the wall to breathe, for anything to prove she hadn't imagined it. Nothing came. Eventually the cold of the archive settled back into her bones the way it always did this late, and she walked back to her desk on legs that didn't feel entirely her own. She didn't sleep that night. She lay still and listened to her own room, hoping to hear the singing again even though she knew it was impossible.

By morning she had almost convinced herself it could be explained away — almost, except that she'd spent three years cataloging this archive's every ordinary echo. She knew, with the same certainty she knew her own name, that ordinary echoes didn't go quiet when you touched them. They didn't ask you for anything.
