  "prompt": "A dark, atmospheric, and gritty medieval fantasy book cover. The central image is a towering, partially ruined stone castle silhouetted against a stormy, bruised purple and deep indigo sky. Jagged lightning forks illuminate the sky momentarily. Below the castle, a vast, desolate battlefield stretches out, strewn with scattered broken weapons (swords, axes), fragments of armor, and the faint, ghostly silhouettes of fallen soldiers partially obscured by mist. A single, tattered banner, its emblem unclear due to distance and damage, flutters defiantly from a broken rampart of the castle. The overall mood is one of desolation, impending doom, and fierce, desperate struggle. The visual style should be painterly yet detailed, with a strong sense of depth and texture, evoking old masters but with a modern fantasy edge. The color palette is dominated by deep blues, purples, greys, and earthy browns, with stark contrasts from the lightning. The composition is square, 1024x1024, with the castle as the dominant vertical element, leading the eye upwards, while the battlefield provides a grounding horizontal element. Professional, epic, and foreboding aesthetic.",
