While Ciri isn’t technically a magic user, she does have some rather mysterious powers which she’ll definitely need to learn more about in the coming season.
Basically, both women are powerful as hell, and I can totally see where self-proclaimed “professional witch” Schmidt Hissrich would have mad respect for that.
Yenn went through hell to become a user of magic and learn to wield Chaos to the benefit of herself and others.
Lauren Schmidt Hissrich noting that she sees all women who “inspire” and “light a fire” under her as part of her “coven,” makes total sense when it comes to The Witcher, as well.
