I am a Wizard. It means someone without magic. In America, they call them No-Majes. I suppose it is only to be expected that differing communities would use different words to describe similar phenomenon. It is quite common. We have those as well. They are called Aurors. Do they really? How inherently? Has anyone happened to document the different types and their uses yet? I imagine the scientists here must have some idea, but then it becomes a curious idea of 'what will a question or some information cost you', so perhaps it is easier to make the discovery on my own.
Are you a witch hunter that practises magic or one that does not?
