A Birthright Ceremony was a ceremony Blood youths underwent in order to be granted a Birthright Jewel. However, not all Blood who participate in the ceremony have enough psychic power to wear the Jewels and don't come away with one. If they do come away wearing a Birthright Jewel, the Blood youth would wear it until they were old enough to make the Offering to the Darkness; a ceremony that allowed the Blood to descend to their Jewel of rank. A persons Jewel of rank was never more than three ranks lower than their Birthright Jewel.
After a Birthright Ceremony, a public celebration was held during which a mother would openly grant a father all paternal rights to the child. Even if the father had raised, loved and nurtured this child, he has no rights to them until he is granted paternal privileges after the Birthright Ceremony.
