Rixx (or Riix) is the capital city of the planet Betazed. (ST reference: Star Charts) The city is also home to the Sacred Chalice of Rixx. Even though it's seen as an old, moldy "clay pot" by Betazoid Deanna Troi, in particular. Her appearance also was the holodeck basis for the deity of their religion, the Rixxan Goddess of Empathy. (TNG episode: "Haven", TNG novel: Q-in-Law, TNG episodes: "Ménage à Troi", "Hollow Pursuits") It is unclear if the city was named after the person, Rixx.
