I write about some of the effects of this kind of magic in the book by Avalonia Books called Both Sides of Heaven.
As you write these pacts are a product of the middle ages and the mentality of the time. Though there may be groups and individuals who deal with such "pacts" in the same manner today, I've yet to encounter any.
