A woman stands on a rooftop at night, holding a glowing book with a cityscape in the background.

In the heart of a bustling city at night, a young woman stands poised against the backdrop of towering skyscrapers, their windows glowing with the warm light of countless lives. Her long, flowing blonde hair cascades down her shoulders, catching the subtle glow of the city lights. She is dressed in a shimmering, metallic gray robe that reflects the ambient light, adding a touch of ethereal beauty to her appearance. Her expression is serene yet enigmatic, as she holds an old, weathered book in her hands. The book, with its yellowed pages and intricate diagrams, seems to hold secrets of its own, as a vivid bolt of lightning crackles across its surface, hinting at the power and mystery contained within its pages. The scene is a blend of urban sophistication and mystical allure, evoking a sense of wonder and the unknown.
