My current vampire household has babies. Cordelia has the Vampire Family aspiration so I have her expanding that family both by turning adults and by having babies. Right now they have two little ones, and her husband had an alien baby before she turned him, so it's a pretty full house. She has turned one adult so far, and that vampire moved in with Vlad. Backstory is that Vlad turned her and he wants her to create more vampires for him, and everyone she does turn then ends up in his brood up in the mansion. She and her husband raise the biological children, who are both vampires even though the oldest was born when his father was still human, and the little alien.
Cordelia is a bit conflicted, sometimes drinking without permission, sometimes asking her mother and siblings for a drink, and she makes a lot of plasma fruit salad. I recently gave her the guilty weakness so she feels bad if she drinks without permission. She's in the botanist career and has a little plasma fruit orchard in the backyard. Her husband Wolfgang is not at all conflicted. He has the public enemy aspiration and does not care what anyone thinks. Every evening as soon as it gets dim enough in Forgotten Hollow he goes out and feeds on one of the walkbys. He never goes to work thirsty (he's working night shifts in the criminal career). He has the withered stomach weakness so he can't rely on plasma fruit, and he doesn't really want to.
I have a lot of interesting ideas for the vampire brood, but I play in rotation with all of Cordelia's siblings so it takes me a while to accomplish goals with any one household. I'm planning on having her turn Ulrike & Maaike from Windenberg, and Raj and Akira from San Myshuno. Then I'm going to do all kinds of crazy story ideas with that household while Cordelia's remains supernatural family play.
