A vast, desolate valley stretching towards the horizon, shrouded in a perpetual twilight. The sky is a deep, bruised purple, bleeding into streaks of fiery orange near the distant, jagged mountain peaks that dominate the background. A thick, ethereal mist clings to the valley floor, swirling around the bases of colossal, petrified dragon bones that litter the landscape, creating an unsettling atmosphere. The bones, weathered by time and etched with intricate patterns, are the only signs of life in this forsaken place. Shafts of pale, filtered sunlight pierce through the oppressive atmosphere, casting dramatic shadows that elongate the skeletal remains, emphasizing their imposing size. The foreground is dominated by the skeletal remains of a large dragon, its ribcage forming a natural archway. The lighting creates a strong sense of depth, highlighting the textures of the bone and the swirling mist. The overall mood is one of loss, remembrance, and the lingering presence of something powerful and ancient. The color palette should be dominated by muted purples, oranges, and grays, creating a sense of both beauty and melancholy. Volumetric lighting is essential.
