Frona is Theo Aetos' wife. She was a high-ranking Mytrosian diplomat to Themis: however, around ten years ago, she made an oath to her husband that she would settle down and never again leave the city for her work in order to prove her commitment to their relationship.
She has two children, Hekate and Kore, with Theo.
Currently, other than her husband, no one else remembers Frona.
