Luna stands face to face with her grandmother in the vault beneath the convent, the ledger still burning in her hand. Her sister watches from the shadows as the grandmother reveals the final piece of the bargain: the cage beneath the altar holds not just their mother's voice, but the soul of every woman in the family line — including Luna's own, waiting to be claimed. In a desperate gamble, Luna strikes a match and sets the ledger ablaze, but the flames do not consume it. Instead, they spread along a trail of oil to the chain that binds the cage, and the mother's voice falls silent. Luna is left with a choice: leave the vault and let the bargain stand, or follow the chain deeper into a darkness no one has ever returned from.
