You are airborne and airborne is part vampire part witch part werewolf and they can have children. And because you can have children vampires are after you. Then you meet the originals (Rebecca, Klaus, Elijah, Kol, fray), who are siblings.

You were walking down the street at night when you bumped into a group

Klaus: what do we have here? I think I just found my food

Rebecca: You mean us

Elijah: oh dear sister you know he would not share

kal:well he will today

Fray: This girl looks so adorable
