Great drawing I have to say, but I do not think she would have the wolf belt, because wolf belongs only to Geralt. But I can imagine such character in a game or book. Great work - I would like to see it in colours one day
As far as I know that wolf is the symbol of the wolf school. There are also other witcher schools. And every real witcher in the wolf school wear one of these amulets to detect magic and monsters. Also, in the game, when you kill barengar, you can retrieve his amulet.
Well, according to the books women can not be turned into witchers becouse of the hormones. I don't really remember what it is exactly but generally it was about the hormonal changes each period. The only female-wither was Ciri but she only received training and was thought about magic by Yennefer. It's a polish book, so it's quite known here.
