tl;dr is katharina is a failed christian mystic turned vampire who has reoriented her faith to center on herself, and has over the years kept a little group of people around herself who basically believe she's the center of the world. she cultivates these intense personal connections with them and makes them grateful for her feeding from them, and a select few that she's closest with she eventually turns into vampires. everyone else she lets die LOL. i'm always sniffing around for people she's trying to recruit, people who are already members, or even people who have lost a friend or a loved one because of her. you can let me know if anything's interesting to you and it's no pressure!
