After watching the newest Fantastic Beasts movie, there are a few ideas established in the movie that I'd love to explore in a slash line. My preference is to create an original world and magical setting but I'd be open to a Harry Potter setting as well.
A powerful sorcerer has gathered around him a fanatical follower base, all determined to see their master's vision of a new world made reality. Their methods are spreading chaos across the world, upsetting the traditional order of the magical world, and threatening to reveal the supernatural to humanity. Character A is one of the Master's most trusted followers and has been tasked with an important mission. -Bring a Character B, potential powerful ally/weapon, to their Master's side. -Take Character B, a valuable new member, under their wing and foster loyalty. Character B could be an enemy of the Master who is infiltrating the group. -Eliminate Character B, an honest threat to their Master's plans or an opposing sorcerer that has gotten in the way too often.
These are very basic ideas that need to be expanded upon and developed between the two of us. I am happy to play either role in any of these.
