- "The Gorn language used a variety of names to describe their homeworld depending upon which aspect of it that the Gorn wish to discuss."
It was located in the Beta Quadrant as the ninth planet in the Tau Lacertae system. Gornar was a tropical jungle world. (ST reference: The Worlds of the Federation) The planet had less of a tilt than Earth and the atmosphere traps much of the heat and accounts for its high warm temperature. Mammals never rose to any type of prominence on Gornar. This lead to the development of the Gorn race. Dinosaur like creatures still roam the wild areas of the planet.
The Gorn built many cities near great swamps. These cities were equally built above and below ground and cover much of the planet. Many connections between cities are found underground. (Decipher RPG module: Worlds)
