As of the 2370s, the Farian government had not been entirely successful in controlling their crime rates. As a result, their planet was a hot spot for Orion Syndicate activity. Several Farians were high-ranking members in the Syndicate in the 2370s, including Thadial Bokar and Raimus.
The planet had organized prostitution.
Physiologically, Farians were quite similar to Humans except for a rising ridge that went from their nose to the top of their forehead. Farius seems to have been a Class M planet with a standard oxygen/nitrogen breathable atmosphere.
In the late 2360s, Farius was a stop on many cargo runs, and this may have contributed to the planet's diversity. The planet was home to a number of species not native to the planet; species seen there included the Bolians and the Dopterians. (DS9: "The Maquis, Part I", "Honor Among Thieves")
The world's planet-wide communications system was a series of com booths, similar to ancient Earth "pay phones". The planet's road system was divided into streets, and public transportation was in place. The planet still used paper currency.
In 2374, Chief Miles O'Brien of Deep Space 9 went to Farius and got caught up in an undercover mission for Starfleet Intelligence. This became worse when the Dominion sent Vorta representative Gelnon to talk with some Syndicate members on the planet, and had several members of the Orion syndicate under Raimus planning the assassination of the Klingon Ambassador. A Human, Liam Bilby, was in charge of planning the assassination, and used his assistants Flith, Krole, and "Connelly" (actually O'Brien working undercover) to carry it out. Starfleet Intelligence pulled O'Brien however, and the assassination was averted. Klingon security took care of the syndicate members. (DS9: "Honor Among Thieves", "Prodigal Daughter")
