Magic doesn't exist in the real world nor does it exist anyplace else, all except for one's mind. The mind is complex, yet it is capable of a lot of things; even the deception that magic exists in such a world. Say that magic did exist, in all of its glory, but would there be only one place where it exists? Or would it be found all over the place?
Unless if magic is only found when someone imagines it to be. After all, it can just be a figment of their imagination. But maybe magic does exist, in the places that you'd least expect it.
