The Farius Planetary Authority was the Farian state in the 24th century. Its seat was the planet Farius Prime. (Decipher RPG module: Worlds)
In the 24th century, it was also known as the Farian Syndicate. (ST video game: Infinite)
It was an oligarchy with a heavy focus on economics and business. It claimed the right to independently prosecute those who broke the law within the system. It had no extradition treaties with any major powers, and handled extraditions on a case-by-case basis. As a result, although many semi-legal and illegal actions were coordinated from Farius Prime, the criminals responsible were wise not to make an enemy of the Farius Planetary Authority. (Decipher RPG module: Worlds).
It had embassies and ambassadors from a number of states. One of these was the Klingon Empire, though it was not a valuable posting. (DS9 episode: "Honor Among Thieves")
In 2346 it was led by Syndic Gaimon. (ST video game: Infinite)
