An ultra-high-definition 4K digital painting showcasing a grand, deserted medieval castle perched on a hill, overlooking a misty valley at dawn. The castle’s ancient stone walls are covered in ivy, and its towering spires reach towards the first light of day, which breaks through the mist with a soft, golden glow. The valley below is shrouded in a blanket of fog, with the tops of trees and distant mountains barely visible in the morning light. The scene is steeped in a sense of history and mystery, with every detail, from the weathered stones of the castle to the delicate tendrils of mist winding through the valley, rendered to create an atmosphere of quiet majesty and ancient power.
