(Star Trek V: The Final Frontier) Its location in the Milky Way Galaxy was depicted in the starchart Data and Picard were studying in stellar cartography in 2371.

In 2267, after the war, the United Federation of Planets and the Klingon and Romulan Empires agreed to mutually develop the planet, in the hopes that it would serve as a model for a new age of peace and understanding. An advertisement broadcasted from the planet claimed it to be "...famous for its wildlife and the fishing is terrific." Individuals who wished to move to this planet could finance their trip through Federation Federal. In reality, the planet was a desert world and the colonists chosen for the undertaking were among the most unscrupulous individuals in the galaxy, quickly taking to fighting amongst each other, fashioning their own crude weapons after the planetary government forbade weapons from them.
In 2287, the Human St. John Talbot was the Federation representative stationed on Nimbus III. General Korrd was the Klingon representative and Caithlin Dar the Romulan. All three were captured and telepathically brainwashed by the renegade Vulcan Sybok when his "Galactic Army of Light" took over the planet's capital and only settlement, Paradise City. By taking the representatives hostage, his plan was to attract a starship to the planet, that he would commandeer to take them all to Sha Ka Ree.
The USS Enterprise-A and Klaa's Bird-of-Prey responded to the hostage crisis. The Enterprise-A was commandeered by Sybok. Captain Klaa followed them, after intercepting a distress call from Captain James T. Kirk. (Star Trek V: The Final Frontier)
