I do believe that scripture, and thus God (and Christ) states quite plainly that witchcraft, sorcery, divination, mediumship, ect... are all sinful activities, and in the OT worthy of being stoned to death. Even Satan took scripture and tried to manipulate it to say what he desired it to say. In the same manner and on the other side of the coin, people take sinful activities and other things, put a distorted spin on them to pretend they are showing God through them. In the end it is still the same as it was in first... sin.
Let us also not forget that the author is no friend to Christianity, nor did she write these books as allegory for scripture. ANY attempt to make these books illustrate an allegorical form relating to Christianity is deception working it's best.. magic. Smoke and mirrors, once done away with reveals the 'illusion' of the lie.
