Themes I Need A Theme Please Help Me?

Hi my names Megan, and I'm writing a novel on vampires(not Twilight vampires, but i am a fan) so i need a theme for a ball, that the vampires will hold at their castle. There will be roses and a chandelier, but i don't know what else to add and what to call it i want it to be a normal name, and i want it to be around Christmas time, but i don't want to call it anything that has to do with Christmas
