Pretty simple, this one: song titles. When I was running my mortals game for the Camarilla UK/Isles of Darkness, I’d often use Lordi song titles to inspire plot.
Probably one of my best plots came from using “Forsaken Fashion Dolls” as the core premise and seeing where it went from there. I started with the idea that maybe abandoned shop mannequins came to life somehow and ended up with a mad scientist who had lost their daughter creating a doll replica of their child, bringing it to life, and then becoming distraught at what they’d created and running off. The doll, left to herself powered by a spirit bound into her “heart” and given the mind of an eight-year old, had reached out in her abandonment and brought friends to her in the form of mannequins she animated unconsciously. That was a rather emotional plot when players got involved.
