A dramatic, atmospheric painting depicting a crumbling, ancient stone castle perched precariously on a jagged, mist-shrouded cliff face overlooking a turbulent, dark sea. The sky is stormy and bruised with deep purples, grays, and hints of fiery orange on the horizon. Jagged rocks, partially obscured by thick fog, surround the base of the cliff. The overall mood is mysterious, foreboding, and epic. The visual style should be reminiscent of romantic landscape painting with a touch of dark fantasy, evoking a sense of isolation, danger, and grandeur.
