Tetragenes

Tetragenes is a developed planet and homeworld of Opera Vectra and Ernest Raviede. Natives of Tetragenes are physically noted for having three eyes, with the third being in the middle of the forehead. A part of Tetragenes may be seen (Opera's quarters) in Opera's main ending.

Tetragenes are one of the oldest civilizations in the universe, along with Nede. Tetragenesians are seen at a meeting with Nedians prior to the rebellion, four billion years ago. Tetragenians are easily recognized by the Ten Wise Men, if Opera or Ernest are part of the group.

Tetragenes maintain a heritage of noble houses and families. Opera is described as coming from a wealthy, noble family.

Aside from Opera and Ernest, a third Tetragenesian is known: Alfred the Butler. Alfred is Opera's personal butler and is encountered in Opera's main ending.

Trivia

 * The name Tetragenes looks to be from Latin, meaning "fourth people" or "fourth family." From tetra- "fourth" and gēns "people," "clan," "family," "tribe." Perhaps the name indicates the Tetragenians are a fourth race of people.
