  "prompt": "A chilling and atmospheric audiobook cover illustration in a square 1024x1024 format. The style should be reminiscent of classic gothic horror art, with a focus on moody chiaroscuro lighting and a sense of profound unease. The central image is a dimly lit, desolate marsh landscape under a heavy, bruised sky. In the distance, shrouded in mist and silhouetted against the faint light, stands a stark, imposing, old manor house with dark, empty windows. A single, spectral, female figure, cloaked entirely in black, is visible standing on a narrow, muddy causeway leading to the house, her form indistinct and haunting. The overall color palette is dominated by deep, muted blues, greys, and muddy browns, with hints of sickly green in the marsh. The mood is one of isolation, dread, and impending doom. The composition should feel claustrophobic yet vast, emphasizing the oppressive environment. The artwork should be highly detailed, with a painterly texture, evoking a sense of ancient, persistent terror.",
