Nivellen, a character from The Witcher, is referred to as 'Fanger' or 'Degen' by the locals due to stories of his 'monstrous' nature. These tales were often used to scare children, painting Nivellen as a fearsome creature. Despite his reputation, Geralt, the Witcher, determines that Nivellen cannot be a true monster as he can touch silver without any ill effects, a trait not shared by most monsters in the Witcher universe.
