Well I don't want her to be old enough that she would have been a slave, because then she would really have to be an idiot to let him go. But she needs to be old enough that she at least knows some of the dangers, So I think I'm going to make her 20 that way there as been ten years since the upraise. Also she would be very close having to prove that she come take the throne. With the humans I think that they royalty will be a birth right in a way but they also have to prove that they would be able to hold it.
