Something I’ve been considering- one of our group’s cinematic touchstones is Only Lovers Left Alive, and one thing I liked about that story is how the vampires found something personal that they cared about (music, books, Christopher Marlowe).
I think adding some intentional touches like that to character development would give more plot-drivers. “The city is on fire and the mortals are dying? Hm, I can always feed in the next town, but I need to get home and save the Stradivarius!”
