A captivating dark fantasy cinematic scene featuring Diana Mariven, a 22-year-old mage of exceptional talent. She is slender, with flowing black hair and confident, striking amethyst eyes. Diana wears a red and white mage robe that accentuates her silhouette while maintaining an elegant and refined appearance. The scene should convey a sense of self-assuredness and sophistication, with a focus on her mastery of illusion magic. The background should be a magical setting with subtle, ethereal effects that highlight her powerful presence without overshadowing her.
