Thyferra is a hot, humid planet located in the Polith system on the Rimma Trade Route. It is on Thyferra where almost all of the Galaxy's bacta is produced.
Thyferra was the homeworld of the Vratix people. The Vratix had already colonized many celestial bodies in the Polith system when they were in first contact with the Republic. Since the Vratix had discovered how to create bacta from alazhi and kavam, the planet became an important Republic world, drawing profit-hungry Human colonists. The Vratix shared the secret of bacta production with their Human neighbors, who eventually gained control of the bacta industry.
As a result, Thyferra was 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.
The Rebel Alliance's bacta supply on the planet was a target set by Grand Moff Kohl Seerdon. In 2 ABY, after setting a diversion on Sullust, he raided the planet to prevent Alliance bacta from reaching the group. However, the plot was thwarted by Rogue Squadron.
In 7 ABY, Ysanne Isard backed a coup that saw a pro-Imperial faction taking over Thyferra. She was also elected head of state by the victorious faction. This allowed her to control the bacta industry. This started a small yet important conflict known as the Bacta War. During the Battle of Thyferra, Rogue Squadron, operating at the time independent from the New Republic—which for political reasons couldn´t directly interfere—liberated Thyferra from the Empire.
Thyferra later joined the Killiks in the Swarm War, the New Jedi Order being unable to defend it from a coup orchestrated by the Killiks. Following the end of the war, Thyferra reverted to Alliance control.
