Thyferra is a hot, humid planet located in the Mid Rim Polith system. Almost all of the galaxy's bacta is produced here. This is the homeworld of the Vratix race who discovered how to create the bacta from the alazhi and kavam plants. The Vratix shared the secret of bacta production to their human neighbors, the result of which is that Thyferra is almost completely controlled by two human-run corporations: Zaltin and Xucphra. These two corporations were chosen by Emperor Palpatine to supply the Empire's bacta, thus eliminating any real competition in the bacta market.
From Thyferra the planets of Korriban and Cinnagar are seen but the planet of Koros Minor is not seen. The reason for this is that the planet of Koros Minor is not seen because of the seven moons blocking it. Together the three planets form a non-equilateral triangle.
The planet was featured in the Nintendo 64 videogame Star Wars: Rogue Squadron. In the game, Grand Moff Kohl Seerdon launched an invasion of the planet to prevent bacta from reaching the Rebel Alliance, starting the Battle of Thyferra. Under command of Luke Skywalker, Rogue Squadron liberated the planet and Skywalker killed Seerdon as he fought in his modified Shuttle.
Shortly after the fall of Coruscant, the Director of Imperial Intelligence and self-proclaimed Empress of the Galactic Empire, Ysanne Isard, fled to Thyferra with two Imperator-class Star Destroyers, one Victory-class Star Destroyer, and the Super Star Destroyer Lusankya. After six months, the new Rogue Squadron attacked and systematically destroyed the Imperial fleet and ended the Imperial control of the planet. After the battle, a joint coalition government, including humans and the Vratix was set up on Thyferra, and the New Republic took over control of the Lusankya.
