Chapter 10 The Oath-Lock

They tested the Oath-Lock on a door of their own making, because Skellick refused to ask the crew to walk a real one blind, and because Ophira wanted to see, with her own eyes, which of them it would refuse. The Oath-Lock was, as far as anyone in the Undercroft had ever been able to work out, a warding that read the intent of the person crossing the threshold. It did not examine what you had done. It examined what you meant. A person could have murdered a hundred men and still walk through it, if they had meant every murder. A person who had never once done wrong could be barred for a single true intention held back. Skellick built the practice lock from the description in an old Cognate treatise that Cadoc had photographed with his memory and recited twice. It was a frame of cold iron with a shallow dish in the threshold, and to cross it you had to say out loud what you wanted, and mean it, with nothing held back. "You first," Skellick said to Boden. Boden stepped into the frame. He thought for a long moment. Then he said, "I want to be a man who doesn't owe anybody anything," and his voice cracked on the last word, and the dish did not warm, and the frame stayed shut, and he stepped out without a word and went to stand against the far wall. "Me," Bettany said, and stepped in, and grinned, and said, "I want to be forgiven," and the dish stayed cold. "You didn't mean it," Skellick said. "I meant it exactly as much as I've ever meant anything." "Then that's the problem." After Boden and Bettany were done, Skellick put his back against the wall and told them the thing he had been holding back, which was the history. The Oath-Lock was not a Cognate invention. It was older than the Aureole, older than the terraces, cut into the cliff before there was a city on the cliff at all, and the first mages of Vessant had built their spire around it the way you build a house around an old well. Nobody knew who had made it. Nobody knew what it was for. What the Cognate knew, and what the treatise Cadoc had recited did not say out loud, was that the Oath-Lock had been opened exactly eleven times in a thousand years, and that nine of those eleven people had been executed within the year, not for what they stole but for what they said when they crossed. Because a person who crosses an Oath-Lock has to say what they want, and it turns out that a person's true want is the most dangerous document they will ever produce. "Kalfax has never crossed it," Skellick said. "He's the Archmage. He's the one man in Vessant who's supposed to be able to. And he's never crossed it, and the Cognate has never explained why, and I've heard three different versions of the story from three different scribes and all three of them end with the same sentence: the lock refused him." "Can a lock refuse an Archmage?" Boden said. "This one can." Skellick looked at the practice frame. "Which tells you something about Archmage Kalfax that the whole city should probably know, and doesn't." Bettany had gone quiet in a way that was unlike him. He was looking at the frame and his hands, which were never still, were very still. "If the lock reads your want," he said, "then the person who crosses it has to want one thing more than anything else in the world. Nothing held back. Not a single reservation." He looked at Ophira. "I've never wanted anything that cleanly in my life." "Nobody has," Ophira said. "That's the point." "Then what makes you think one of us can do it?" "I don't know that one of us can," Ophira said. "I know that one of us has to try, and I know that Cadoc is the closest, and I know that if he can't do it, then we've spent six days building a job that ends at a door nobody in this crew can open." She did not say the rest of it, because the rest of it was that she intended to try it herself, in private, after the others had gone, and she had a fair idea of what the lock would find when she did. Cadoc went next. He stood in the frame for a long time. His hands were clasped in front of him like a man at prayer, and he was not a praying man, or he had not been before this week. "I want my sister to be free," he said. The dish warmed, faintly. A hairline of pale light went around the frame, near the top, and held, and then guttered and died because Cadoc, at the last second, had thought about the twelve silver, and about the slip in Braccus's pocket, and about the difference between wanting his sister free and being willing to pay for it. The Oath-Lock had read all of it at once. "That was close," Skellick said. "You're the closest any of us have come." Cadoc looked as if he had been told he had a fatal disease and had a year to live. "I want it," he said. "I want it more than anything." "I believe you," Ophira said. "But the lock believes everything." She stepped into the frame herself last, when the others had gone to eat, and she did not tell them she was going to, and she said nothing clever. She thought about the fourth tier of the Aureole and the cabinet that was in no inventory and the small black book inside it, and she thought about her mother's name, and about Harlo, and about the fact that she had told this crew a lie about the slip and a half-lie about the book, and she held all of it, and said: "I want the people in that book to know what was done to them." The dish warmed. The frame lit from bottom to top in a single clean line, and the door did not open, because it was a practice door and there was nothing behind it, but the light stayed steady for the length of three breaths, and then she stepped out and let it go. She stood in the empty hall for a moment afterward with her heart going hard. The Oath-Lock had accepted her. Which meant the darkest room in the Aureole would open for a woman who had just lied to five people, so long as she wanted the ledger more than she wanted any of them to be safe. That was the joke, she thought. That was the whole ugly joke the Cognate had been making for a thousand years. The lock didn't want a good person. It wanted a person with one thing they would burn the world for. She climbed back up through the Undercroft with the answer she needed, and did not tell anyone, because telling them would have cost her the answer. She knew what it meant. She had known the shape of it before she ever stepped into the practice frame. The lock would open for her because she wanted the ledger with nothing held back, and if she wanted the ledger with nothing held back, then Cadoc and Skellick and Bettany were not people to her at all. They were the price. A job with a price is a job that has already named its casualties, and she had spent three years telling herself she would never build one of those again, and here she was on an ordinary night, building one, on purpose, in a cellar, with her name on nothing and her want on everything. ---
