What are the families like? Just like, coven of vampires living together? I'd be willing to take the head for one depending on this (and what McHaggis' head is gonna be like). 

Also are there more vamp weaknesses other than sunlight? Fire? Wood? Silver?

Also I wouldn't make a point to put a limit on weapons. Most people are pretty reasonable about them. Like "one weapon allowed" is just an opportunity to make a ridiculous weapon when allowing two simple ones might make more sense. But, in my opinion, vampires don't really need weapons anyway, lol
