Duradel was a nice and loyal vampire but if you get on his bad side you will pay. 

He serves under Queen Lilith as her most trusted and loyal butler along as her lover which no one knows of. 

They fell in love the first time they met under their favorite willow tree. It is also where they shared their first kissed and where Lilith changed Duradel to a vampire. 

It was such a happing ending for them both to be able to love each other for all time.
