A Stunning photo-realistic, 32k, Basque Civilizations, HD wallpaper, High-quality, Hyper-realistic image of a fantastical landscape. A majestic, moss-covered castle stands atop a verdant mountain, waterfalls cascading down its sides. A tranquil stream flows through a lush forest, leading towards the mountain. Ancient, gnarled trees flank the stream, their roots intertwined with rocks and vegetation. In the foreground, a partially ruined stone structure, overgrown with ivy, provides a sense of age and mystery. Figures, possibly travelers or guardians, are subtly visible in the distance. The lighting is dramatic, with soft light filtering through the trees and illuminating the castle. The image should be highly detailed, with realistic textures and lighting effects, aiming for a cinematic and immersive quality. High resolution, suitable for a high-quality wallpaper.
