Vilgefortz is an interesting character. Sapkowski certainly made sure he was plenty easy to hate. Not just by bothering Geralt, Ciri and Yennefer but because he’s a little overzealous in general when it comes to disposing of human lives in general.
My Witcher lore videos are not meant to replace playing the game series or reading the books. Seriously, the novels are really good and I couldn’t possibly convey every detail by just telling you about the events and characters. Go read the books, play the games, then come back to tell me how awesome the Witcher series is.
