Greater Hertha

Origin and status
The Great Gerta is a member of the 83rd Society of Geniuses, an emanation of Erudition, and the owner of the space station of the same name—a testament to her extraordinary intelligence, abilities, and authority. As a member of the Society of Geniuses, Gerta discovered a way to halt aging by creating hundreds of dolls, granting them autonomy, and a means of "transferring" consciousness between them. Gerta herself is, one might say, the original of the dolls that accompanied the Pioneer on the Gerta station. She is also one of the creators of the "Virtual Universe"—a simulation that allows one to seek contact with the aeons.

Personality and character
Despite all her virtues, Gert is a rather eccentric individual and will stop doing anything that doesn't interest her. She lives secluded in a clock tower at the edge of space and devotes all her time to uncovering the secrets of the universe, as if she were practicing magic. She despises mundane tasks, so she usually delegates them to her puppets. She does only what she wants, and as soon as she loses interest, she abandons her project; the best example of this is the space station, which she controls through puppets.
The character's lines reveal her self-confidence and impatience with others: she demands obedience from her doll assistants, graciously accepts their praise ("Mrs. Gerta is a rare diamond," "Mrs. Gerta is an unrivaled genius," "Mrs. Gerta is the embodiment of beauty") and impatiently waves them off, urging them to get down to business.

Appearance
Gerta's appearance is that of a mature and eccentric scientist. She sports long, ash-brown hair with purple tips, appearing more mature than her puppets. Her hair color has a more lilac tint, her skin is fair, and her eyes are violet. Gerta's signature style is an elaborate black, white, and purple dress with an open back, a sweetheart-shaped corset neckline, long skirts, and a wide-brimmed hat adorned with flowers. Her appearance also references stereotypical witches: a pointed hat, a purple dress with a black corset, longer at the back, and a key-shaped staff that allows her to fly. Thanks to rejuvenation technology, she retains the appearance of a fragrant young woman, although Gerta's exact age is unknown—her biological appearance corresponds to approximately 20-25 years.
