“Has it ever occurred to you that maybe you’re sane? That you’ve always been sane? That perhaps you’re the sanest person in the city?" "I hope not," whispered Neverfell. "Because, if I’m sane, then there’s something wrong with Caverna, something horrible and sick, and nobody else has noticed. If I’m sane, then we shouldn’t be sitting around talking – we should all be clawing our way out as fast as we can." "Oh, I don’t think she’d like that," the Kleptomancer remarked, with a hint of affection in his voice. "She needs us. Without us, there is no her, after all. She is the city, not the tunnels, and so she does everything she can to keep us down here. Sometimes I even wonder whether it is only possible to create True Delicacies here because she gives them their power, as a bribe to stop us leaving. When the Grand Steward declared that nobody was allowed to enter or leave the city, I believe he became her chosen beloved. I will tell you something else, though I cannot prove it. The city grows, and not just through the effort of pick and shovel. She has been stretching, spreading and contorting to make room for us all, and I think that is why geography no longer makes sense.”

“For a second, she could almost see Caverna as the Kleptomancer did, a murky, monstrous beauty, smiling her fine-fanged smile as she prepared to stretch and grow, shaking out her tunnel-tresses as they became longer and longer. Perhaps Caverna had already known that such an opportunity was open to her. Neverfell imagined her discarding the Grand Steward like a worn-out toy, and reaching for a new favourite, a man who could extend her empire and bring her new strength . . . Maxim Childersin.”

“This was why he had become a master thief, to achieve this theft of thefts, this masterpiece of larceny. All the time, fascinating and terrible Caverna had been his goal. Whilst other Cartographers had sighed in vain after the beauty of her treacherous geography, he had decided to win her with cunning and threats. All along Caverna had been his opponent and his prize, and she had never suspected it for a moment. He had fooled her, fought her and defeated her. She would be furious, no doubt, would hate him, rail against him and look for ways to destroy him, but he had outmanoeuvred her and now she had no choice but to play things his way. Unlike her earlier favourites, he was her lord, not a plaything to be tossed aside when she was bored. And yet, for the first time in ten years, he found himself at something of a loss. I have succeeded. I have won. I rule the city. I wonder what I was planning to do with it?”

“She’s got us, she’s got us all. Caverna. She doesn’t want to let us go. Do you know what she’s like? A huge trap-lantern with us inside her, digesting us really, really slowly, and not wanting to let any of us go. Maybe that’s the worst kind of prison – not knowing you’re in a prison. Because then you don’t fight to get out.”

“Sometimes she felt she would like to engulf him like a trap-lantern, and never share him with anyone or anything else again, not even the light. Even his obsession with ruling Caverna pained her, as if the city were a woman, and a rival.”

“I understand Neverfell, you see. For Neverfell, it is as if other people are part of her. When she believes they are in pain, it hurts her, like a wound in a pretend limb. So right now she is in pain for all the people she saw in the Undercity.”

“I no longer draw up maps – and maps are a Cartographer’s love letters to Caverna, his way of serving and worshipping her. She is in my thoughts all the time, but I am no longer her slave.""Then you still . . . love her?" asked Neverfell, struggling with the notion. "More than ever," her companion answered softly.”
