The Sacred Chalice of Rixx was a chalice of historical importance to the people of Betazed. In the 24th century the chalice was in the possession of the Fifth House of Betazed. Lwaxana Troi would quite frequently remind people that she was the holder of the chalice, in addition to being a daughter of the Fifth House and heir to the Holy Rings of Betazed.
