The figure features a soft vinyl body with smooth sculpted anatomy, a finely painted face-up with delicate blushing, and large expressive eyes rendered with layered shading. Long flowing synthetic hair is rooted to a realistic scalp and styled to match the character's signature look.

Articulation at the neck, shoulders, elbows, wrists, and hips allows varied posing and display options.

Etheldreda is a central figure within the Zanmataisei Demonbane mythos, often portrayed as an enigmatic and dignified woman whose knowledge of ancient technology and arcane lore influences events around her. In many interpretations she serves as a guiding presence to protagonists, balancing a reserved exterior with deep compassion and a strong sense of duty. Her background suggests ties to lost civilizations and forgotten sciences, making her both a repository of secrets and a moral anchor in crisis. Stories frequently explore her internal conflict between past responsibilities and present relationships, revealing layers of sacrifice, loyalty, and quiet resilience as she navigates alliances, mysteries, and the consequences of awakening powers beyond ordinary understanding.
