Paranormal Murder Mystery RPG

I'll probably edit this later for a bit more detail but as of now...

GENRE AND SETTING

Genre: Urban fantasy / mystery

Setting: Big, modern day city

 SUPER BASIC PLOT:

Tensions between humans and vampires have increased rapidly over the years as a natural resource, [super awesome-sounding natural resource name], is being fought over. Humans have found this resource to be of significant religious value to them, while the vampires seeks it for supernatural powers. We find our two antagonists, one human and one vampire, team up in an ironic plot to stir the two species into a war by committing a kidnap/murder on two humans, the murder of a husband and the kidnapping of a wife, who happens to be the daughter of the president.
