Lilith and Vlad were married and living in the large house. But a rival pack of vampires (Dina Callinate, Alexander Goth, and their leader Max Villareal) set fire to the place, and killed them off.
Dina, Alex and Max were murdered during the Great Werewolf/Vampire war, after Max killed Jacob.
The ones who are still around are Morgan Fryers (she lives somewhere else) and her son (who loves partying and people - but the bloodsucking thing is turning people off. He's young and will figure it out). He lives in Forgotten Hollow. He's living with vampire Luna Villareal, who just got dumped by vampire Caleb.
Wolfgang hated being a vampire, ran away, and lived with the love of his life, Cassandra Goth. After Cassandra cured him, she decided to infiltrate the vampires and take them down. She lives with her now-boyfriend Caleb. And enjoys being a vampire.
Alexander's mom, Bella, brought Alexander back from the dead. But apparently he was brought back without a soul. He lives with his girlfriend, Lilith Pleasant, and is all sorts of trouble. They often kidnap people to feed on them. And Morgan Fyres comes in and cleans up their messes.
