Farius Prime was the inhabited prime planet in the Farius system. It was the homeworld of the humanoid Farians. Politically neutral, this world was a major trading destination for many species and hosted the embassies of several galactic powers, including the Klingons.
It was not particularly distant from station Deep Space 9, and freighters frequently traveled between the station and the Galador II. Surprisingly, the planet maintained diplomatic relations with the Klingon Empire. Paper currency was in use on the planet. (DS9: "The Maquis, Part I", "Honor Among Thieves")
Among its attractions were races, and prostitution.
Farius Prime was also the headquarters of a large segment of the Orion Syndicate criminal organization. In 2374, Miles O'Brien was sent undercover by Starfleet Intelligence to the planet to infiltrate the organization and build a case against some of its members. Many Farians were also members of the Syndicate. Such individuals included Raimus, Flith, and Thadial Bokar. (DS9: "Honor Among Thieves", "Prodigal Daughter")
