Codatski@JacobBurgess, you're the only person I'm aware of who has authority on this kind of question.
Jacob Burgess@codatski Oh, I like this very much. It depends on the Vampiric paradigm we're talking about, but keys go with the classic one as I understand it.
The prohibition of entering a home is because the vampire is unnatural and unwelcome in a space that is a part of another person's life. They must be invited into that person's life, essentially.
I would say this would be situational depending on how much part of society the dweller felt and further would need to see the warrant for entry.
