Thyferra
this planet, located in the Polith System, produced much of the galaxy's bacta. A temperate world with two moons, it is the homeworld of the Vratix race, which discovered how to create bacta from alazhi and kavam. The Vratix shared the secrets of bacta production with their human neighbors, and a healthy business was created as the galaxy realized the healing potential of bacta. The planet had two human factions engaged in bacta production, the Zaltin and Xucphra factions, in addition to the Vratix Ashern faction. The two human factions were chosen by Emperor Palpatine to supply the Empire's bacta, effectively eliminating all competition in the bacta market. The Vratix were relegated to the position of rebellious terrorists, until they petitioned the New Republic for admission as a member race. The Republic was unable to do so without the consent of the native human population, which was under the yoke of Ysanne Isard until she was killed in the Battle of Thyferra. Once free of Imperial domination, Thyferra applied for membership and was accepted. The Vratix then expelled the human leaders of the bacta cartels, and took control of its production for thenselves. Unfortunately, the Vratix were no match for the Yuuzhan Vong, who invaded the galaxy shortly afterward. The Yuuzhan Vong control of Thyferra casued serious problems to the New Republic, which had to rely on existing stockpiles of bacta to supply their military medical facilities. In a series of hit-and-run attacks, New Republic forces eventually defeated the alien invaders and recaptured the planet. The average day on Thyferra lasts just over 21 standard hours.
