" Well, here he was. They could save each other, the way the poets promised lovers should. He was mystery, he was darkness, he was all she had dreamed of. And if she would only free him he would service her - oh yes - until her pleasure reached that threshold that, like all thresholds, was a place where the strong grew stronger, and the weak perished. Pleasure was pain there, and vice versa. And he knew it well enough to call it home. "
― Clive Barker , The Hellbound Heart
