The Birthright Ceremony is performed between the ages of 8-10 in appearance and this is a very special time in the society of the Blood. This is their first step in getting the power that they will wield when they are adults. The Ceremony is always performed by a Priestess at an altar and it is a gathering of family and friends. The child undergoing the Ceremony will receive a Birthright Jewel between White and Red, though there is a small chance that they will not be given on at all if they are simply a Blood Female or a Blood Male. Just because they do not receive a Birthright Jewel does not mean they will not be able to receive an Offering Jewel when they give their Offering to the Darkness.
The Birthright Ceremony is also the time when the father is acknowledged by the mother and paternity is either granted or denied.
