Unnamed Fabrini
A list of unnamed Fabrini.

Citizens 
These Fabrini citizens lined the corridors when James T. Kirk, Spock, and Doctor McCoy were captured and brought underground on Yonada. ()

Guards 
These soldiers attacked and captured James T. Kirk, Spock, and Doctor McCoy when they beamed to the surface of Yonada a ten thousand-year-old asteroid-ship, built by the Fabrini. ()

Old man 

The old man was an inhabitant of the Yonada, a ten thousand-year-old asteroid-ship built by the Fabrini when they realized that their home sun was about to go supernova. Yonada was on a collision course with the populated planet Daran V and James T. Kirk and Spock attempted to alter its course. The old man and the rest of the people of the asteroid spaceship were not aware that they were on a ship and believed it to be their homeworld. Their deity, the Oracle, was a computer programmed by the ancestors of the people of the Yonada to guide the ship. The old man wore the instrument of obedience, which punished wrong thinking. 

Even though the old man was wracked by pain by the device, he told Kirk that many years ago he had climbed the mountains, even though it was forbidden, and touched the sky. The device killed him as he finished his story. ()

Oracle guards 
These guards were summoned to the Oracle room by Natira when Kirk and Spock were caught eavesdropping there. ()

Servants
