Or better yet make them predominatly Chinese, they own those little chinese buffets you see in every minimall and shopping center. The ones where you eat four plates of food and an hour later your starving agian.
Worst Jade Court Vampire idea ever.
Joking aside, there are two threads to consider:
1) What is conceivable within the fictional guidelines laid down between the novels and the RPG?
2) What will make an entertaining mystery, adventure or character?
Some of the ideas presented are not as feasible from the strictest interpretation of the WCV's predatory preferences, but they can still be cool. If Toe-Moss can "sip" from clientele at a particular establishment then others could. They could even be temporarily trying it out because of some personal conflict of their own.
My thoughts:
At the most basic level, WCV can incite and then feed on an extreme emotion, killing their victims in a way that is very difficult to diagnose by modern medicine but which may not directly reflect the way they died.
When a victim has been drained during lust and found
in flagrante delicto, one can maybe draw a line there. People who are "scared to death" by a fear-drinking WCV may have a rictus of fright on their face, which could be a clue. Both of these seemed to present as cardiac troubles or a brain hemorrhage.
But someone who was fed on while Gluttony was being drained may present with a stomach full of food, but they needn't have literally eaten themselves to death like the Gluttony victim from "Se7en" (
who IIRC was actually kicked to death and died from internal hemorrhaging - OMG, I spoiler-tagged this incredibly old movie
). They may actually present like the Fear or Lust victim.
Gloom and depression muddy up the field a bit because usually the victims usually succumb to suicidal thoughts and kill themselves, but those are I think convenient distractions from the actual mechanism of feeding.
