A vamp AU question

Something I write through the haze of "I should be in bed already": I offer anyone who wants a thought exercise to come up with their own vampire/servant duo (potentially followed by a witch and/or were-being). What are they like, how did they meet, which court does the vamp belong to (if any), etc.

Asking because I want to do some more vamp AU stuff (in addition to a million other things) and this might serve as inspiration. XD
