Craft a female character that is both a creature of nightmares and a vision of desire—a being that embodies the darkest fantasies and deepest fears of those who encounter her. She should possess a form that is simultaneously grotesque and alluring, with twisted, unnatural features that inspire terror, yet a beauty that is undeniable and hypnotic. Despite the horror she evokes, there is a magnetic pull to her, a seductive power that draws others in with a promise of forbidden pleasure and danger.
