Scientific disciple of magical art - depends how you look at it really
Folk magic is more of a magical tradition than a school of scholarly research being as old as the hills, some say as old as time itself. It is as deeply ingrained to the psyche of the country folk as the changing of the seasons and has been passed down from father to son and mother to daughter for countless generations.
In a small inn (the more remote the better), a man turns up dead. There are no wounds on his body what-so-ever, and he aboslutely reeks of garlic.
The man died of a curse that forced him to eat a clove of garlic a day or suffer the penalty. This gets really interesting if the body somehow appears on top of a someone the villagers are suspcious of.
