As I was researching the Zhong Lung/Same-Bito connection, I came across a Zhong Lung Flaw that only appeared in the Breed Book 6 - Mokolé:
Fertile Essence (1 point Flaw)
You are filled with life-giving Essence, to the peril of anyone who knows you. If anyone drinks from the same glass as you, uses the same bathing pool, or even handles your clothing or utensils, they can have children who resemble you. Even people who are sterile or barren might become pregnant because of you (Storyteller's opinion, and certainly not applicable to metis characters). This can become annoying, and cause serious misunderstandings.Breed Book 6 Mokolé p76
As it is worded, it seems to imply that the bearer of the flaw is male, spreading his genetic code by touching people. But what is the implication for a female Zhong Lung with this trait? Will she suddenly be the (spiritual?)father of children of other people?
I have not been able to track down this flaw in any other edition, so it might be endemic to this one rulebook because of it being... game breaking. I mean, it certainly IS game breaking when the Dragon King takes a bath in the cistern for Shanghai and ends up starting a Baby Boom...
