Ancient gothic castle towering above a misty mountain valley

A vast ancient Gothic castle perched dramatically on a towering rocky cliff, overlooking a deep misty valley. The castle is dark, grim and imposing, built from massive weathered black and charcoal-gray stones, with towering battlements, narrow arched windows, ruined towers and jagged Gothic architecture. A winding mountain road snakes up the cliffs toward the castle, along which a large host of medieval knights marches in formation, carrying banners, spears and shields. In the foreground, sitting alone on a rugged rock, an old hooded monk leans heavily on a long wooden staff, his weathered face thoughtful and solemn. Dark storm clouds gather above the castle, rays of cold light breaking through the clouds, mist drifting through the valley, dramatic atmosphere, epic medieval fantasy, cinematic composition, atmospheric perspective, highly detailed stone textures, realistic medieval clothing and armor, moody chiaroscuro lighting, dark desaturated color palette, monumental scale, mysterious and haunting, epic historical fantasy painting --ar 16:9 --stylize 300
