Ramatis III

Homeworld of the mediator Riva

The home planet of Riva, the celebrated deaf mediator whose ruling family has for generations lacked the gene for hearing and speaks through a chorus of interpreters.

Ramatis III is the homeworld of Riva, one of the most respected negotiators known to the Federation. It appears briefly in the second-season Next Generation episode Loud as a Whisper.
In 2365 the Enterprise-D travels to the planet to collect Riva and take him to Solais V, where two factions have been at war for centuries. Picard, Troi and Worf beam down to his elegant hall and learn that he is deaf, as all members of the ruling line of Ramatis have been. He communicates through three companions known as his chorus, each of whom voices a different side of his nature.
Riva's past work included helping to negotiate treaties between the Klingons and the Federation. After his chorus is killed on Solais V, he chooses to stay there and teach both sides his sign language.
