Reasons for banishment? (Fictional Story)?

ooh i do love a writer in the process of creating lol. I am a big fiction fan. I think it is a hard question, because u are the creator. Think about where u want her to be in a couple of chapters, or even at the end of the book or next book and how the conflict changes her and the cheaters the problem may introduce, it can help developing the conflict. Do u want her to have created the crime and be a kind of rouge witch, or unjustly betrayed? maybe she uncovers a conspiracy or betrayal inside the witch community? Also whats ur targeted readers? Young adult, or adult? That helps when making the conflict knowing the maturity level of the readers. Look on goggle and read online writers forums, there is a lot of writers out there more then wiling to help out new writers, but be wary when sharing ur story, u don't want someone to scam it out from under u. Good luck!!
