Luna stands between the woman who was once a library and the scarred other Luna, the ink in her veins burning. The woman claims the curse is a prison she chose to protect the world; the other Luna says it's a lie to trap a successor. Luna asks for proof, and the woman offers a book: the original contract, written in blood and bone. But when Luna touches it, the ink in her veins surges, and she sees the library's origin—a woman named Elara who made a deal to save her village, only to become the shelves and the stories. The scarred other Luna pulls her back, revealing that the woman is not Elara but the library itself, wearing a dead face. Luna must decide whether to sign the contract and become the new library, or burn it and risk the stories consuming the world. She chooses to burn it, but the fire does not touch the paper. The woman smiles, and the library groans. Luna realizes the contract cannot be destroyed—only rewritten. She picks up the bone pen, and the ink in her hand rises to meet it, ready to write her own ending.
