Indeed... but what I am saying is, the story is a fantasy, so why would real-world methods enter the plotline at all, other than to create a juxtaposition?
I can see that you may feel the need to set the scene with this, but surely you only need to to 'skim over' the first part and get straight into the soul-selling—which is much more interesting in a book.
Granted, you may want to pad this out if it were a movie or screenplay, but it isn't, it's a book. It works a lot differently.
I would primarily concentrate on building the character of the magician BEFORE the accident, rather than worry about methods.
In fact, surely your 'method' can be fantastical too, as who KNOWS how it's done, right?
