14th Generation
2 point Flaw
You were created five or fewer years ago by a member of the 13th generation. though you have 10 blood points in your body, only eight of them may be used to heal wounds, power Disciplines, raise Attributes, etc. Obviously, taking this Flaw precludes you from taking the Generation Background, and you may not start with Status either. YOu are likely a clanless Caitiff, for your blood is probably too thin to pass down the distinguishing characteristics of a clan. Most 14th-generation vampires should also take the Thin Blood flaw.
As time progresses, such characters can gain age if they are lucky and skilled. Change "five or fewer years ago" to "after the dawn of the 21st century." -Jamie
