Imagine Umbraea, an ancient and powerful being exiled to Earth, now disguised to blend in with humanity. She appears as a young, innocent woman, her ethereal beauty softened to avoid drawing attention. Her dark, flowing gown has been replaced by modern, subtle attire: a simple, elegant black dress that hints at her mysterious nature but is unassuming enough to pass unnoticed. The dress is form-fitting, with long sleeves and a modest neckline, yet it carries a subtle sheen, reminiscent of the shadows she once commanded. Her long, black hair falls in loose waves around her shoulders, framing her delicate, almost translucent skin. Despite her attempt to blend in, her eyes—gray or pale blue—retain their cold, intense gaze, a window to the immense power and ancient wisdom she possesses. Her face, though youthful and serene, bears a faint, almost invisible scar in the shape of a rune, a remnant of her true identity. Umbraea's presence is muted but still carries an undercurrent of her true nature. Her posture is graceful, almost ethereal, and she moves with a quiet elegance. The setting is a bustling city street at twilight, with people passing by, unaware of the powerful being among them. The sky is tinged with the colors of dusk, and the city lights are just beginning to flicker on, casting a soft glow on the scene. Umbraea stands near a streetlight, the shadows subtly bending towards her, hinting at the power she still holds despite her efforts to conceal it. The image should capture the contrast between Umbraea's attempt to appear as an ordinary human and the subtle signs of her true, otherworldly essence. She should look youthful and innocent, yet with an underlying sense of mystery and depth that sets her apart from those around her.
