I was thinking a couple of weeks ago about writing a story about a witch in the Harry Potter world. It wasn't going to include any of the characters or events that JK wrote about: it was going to be an original story about a witch born into a muggle fundamentalist-Christian family (imagine how tricky that situation would be). The things taken from Harry Potter would have been the different sorts of magical creatures, the fact that there is a ministry of magic, the historical background, the spells and, of coarse, Hogwarts.
Anyway, I got over that idea pretty quickly but it got me thinking: would my story have been classed as "fanfiction"? Where is the line drawn between fan fiction & original fiction? Are there certain unwritten guidlines about this sort of thing?
I thought this was a pretty interesting topic, so give me your opinion . . .
