Newblood is a flexible term, but usually refers to any vampire less than 500 years old. There are relatively few Oldbloods around when compared to newbloods, but those that are around are really deadly. Like Tristan, Magnus, and Pipistrelle.

Of course, the title is also used to refer to status. A more powerful and imposing vampire might be called 'oldblood' at 400, whereas a less imposing vampire might not earn the title until 600. Being less impressive in the eyes of other vampires means it takes more time.
