@RandomNoodels no clue, but they have a whole area all to themselves in my brain. They're so malleable. They're just monstrous to stand out but human enough to blend in. They're social creatures, pack animals, like us
and their often considered enemy, werewolves. You'll rarely find a solo vampire (that's why they're always hot). depending on the mythology or series lore, their concrete strengths and weaknesses can vary. also, vampirism is based off rabies symptoms. ya know, the disease that if you present symptoms you're doomed to die from. :)
