The Fabrina solar system was an inhabited planetary system. The system consisted of a primary named Fabrina and eight planets. One of these planets was the homeworld for the Fabrini. In 8,000 BC, Fabrina went nova and destroyed its system. This system was depicted in the Book of the People. (TOS: "For the World is Hollow and I Have Touched the Sky")
This system's quadrant of origin is inferred based on the position of its star as seen in the star chart appearing in Star Trek VI: The Undiscovered Country.
