"Design a comic book cover featuring a mysterious and adventurous atmosphere. In the center, a young, brave heroine with short, windswept hair and wearing a futuristic leather jacket stands on a rocky cliff, overlooking a dark, stormy ocean. In her hand, she holds a glowing, ancient artifact that casts a soft light around her. In the background, an abandoned, futuristic city with towering skyscrapers is half-buried in sand dunes, blending into the storm clouds above. The title of the comic, 'The Lost Relics', is boldly displayed at the top in a futuristic metallic font. The overall color scheme is dark, with shades of blue, gray, and flashes of neon green from the artifact's glow, creating a sense of tension and discovery."
