The death offering was a Barrayaran ritual in remembrance of the dead. A lock of hair or other personal item was burned on the grave of the dead for the peace of the dead person's soul. Before making a death offering, it was obligatory to fast. A public death offering was part of Barrayaran funeral practices.
Cetaganda held a public death offering for the Dowager Empress Lisbet Diagtar, in which priceless cultural artifacts, bier-gifts, from planets all around the Nexus were burned in a nuclear pyre. It is unknown whether Cetaganda had personal death offerings as Barrayar did, or if it was reserved for high-ranking royalty.
