Riva's Chorus was a trio of telepaths who had lived with Riva since his childhood and who were extraordinarily attuned to his thoughts and emotions. Riva himself was deaf, a hereditary condition of the ruling dynasty of his planet, Ramatis III, and the chorus interpreted his thoughts and spoke on his behalf.
The trio each spoke for different aspects of Riva.
- The "Scholar/Artist" spoke on matters of the intellect and creativity, providing analysis and insight.
- The "Passion/Warrior" (or "Warrior/Adonis") spoke only when Riva's spirit was moved or excited.
- The "Woman", the only female of the trio, was the balance that held the other two together, providing harmony and wisdom.
The bond between Riva and his Chorus was nearly symbiotic. They were his good friends and the relationship between his family and their ancestors, who served the same role, stretched back generations.
In 2365, Riva's Chorus was murdered on Solais V when he attempted to bring two warring factions together. The loss of his communication abilities and dear friends was nearly a crippling blow for Riva and he felt responsible for their deaths. Ultimately, however, he resolved to finish the task and dedicated himself to bringing peace to Solais V. (TNG: "Loud As A Whisper")
