Kind Of Magical
Magic exists only in the mind. That doesn't mean it's not real. It is elusive, though, as everything a wizard does can be attributed to suggestion, probability and intuition. It doesn't help its reputation that most wizards are accomplished illusionists. Yet they do things other people cannot. Magic simply works.
But that's not the only mystery out there. Things go bump in the night, and while nobody can prove they saw anything, the traces they leave often reveal knowledge no prankster could possibly have.
