Fergriss Pharmaceuticals stood out as a large enterprise that exerted control over the contaminated Core Worlds planet of Balosar during the Galactic Empire's rule. This firm, together with its competitors on Balosar, such as BioTech Industries, consistently participated in corporate spying and acts of sabotage against each other, all while guaranteeing that the Empire overlooked any illicit actions by providing significant bribes to dishonest authorities.
Within the current Star Wars canon, a reference to Fergriss Pharmaceuticals can be found in Cyphers and Masks, a 2018 sourcebook for the Star Wars: Age of Rebellion RPG created by Fantasy Flight Games. The corporation initially appeared in the Star Wars Legends timeline, specifically in Galaxy Guide 11: Criminal Organizations, a 1994 book authored by Rick D. Stuart for West End Games' Star Wars: The Roleplaying Game.
