I am writing a vampire novel and my main character in the story (in his past life) apprentices under an enchantress/sorceress in order to learn the craft of magic. She only allows him the opportunity because he posseses a special gift. He leaves her in the end because she plans to do something to harm humanity or someone of a higher power, but who and how? She curses him with ultimate death by a human figure, and unknowingly he finds a loop hole when he is bit by a vampire when he is in hiding. I am stumped on those aspects of my preface. The preface is set in the 18th century. Thanks.
