The Vratix were a species of sentient insectoids from the planet Thyferra. They were the inventors of bacta, a gelatinous substance that encouraged the rapid healing of serious injuries. The production of bacta gave Vratix an almost mystical pleasure. It had such an intoxicating effect on them that they almost felt the need to produce the substance.
After discovering the healing properties of bacta, the Human settlers of Thyferra began to exploit the Vratix addiction. They encouraged them to produce more and more bacta, which they then sold to the general public. The Vratix eventually became a slave labor force, while the settlers made huge amounts of money.
