A woman stands majestically before a sprawling city under the night sky, her presence illuminated by a golden halo that shimmers like an otherworldly crown. She embodies a portrait of a knightly heroine, her armored attire intricately detailed in steampunk fashion, with cogs and gears subtly woven into the metalwork. Her gaze is resolute and commanding, capturing the essence of a neo-gothic empress. The city behind her, a marvel of industrial wonder, twinkles with lights that reflect her regal poise, painting her as a guardian of this enchanting urban realm.
