Ghtroc Industries, a well-regarded builder of starships, had its main offices on Clak'dor, the native planet of the Bith people. They were famous for creating the 690 and 720 small transport designs, but the company ceased to exist following the economic disaster of their Cargo Empress super freighter.
The initial reference to Ghtroc Industries occurred in Rebel Enslaved!, a 1991 supplement for the Star Wars role-playing game belonging to Star Wars Legends. Later, Ghtroc Industries was brought into canon via Before the Awakening, a young adult book authored by Greg Rucka and released in 2015.
