I've recently found myself with a stroke of creativity during physics class and jotted down some quick notes, and now am seeking to better organize the ideas. What I have right now is just a simple web showing different characters and their relation to one another, see attached. Also, I am terrible when it comes to names of characters, so any help on better names would be much appreciated.
The general gist of the story is as follows.
The main character gets caught up in a blood feud between a family of mages and a family of vampires after his parents are murdered due mistaken identity, romantic hyjinks and drama follow.
I was planning on having the setting be in Seattle (I am a local here so I know the area, and it is fairly recognizable).
The point of this thread, other than being a gauge to see how well this kind of idea would be received, is to get advice on how to organize the actual scenario lay outs into a manageable form. Also, is this kind of character relation plotting a good idea?
