Thyferrans are human colonists of the planet Thyferra. During the days of the Old Republic it was there that the value and potential of bacta as a healing agent was discovered and the Thyferrans started working together closely with the Vratix to produce bacta for supply to the galaxy.

Business is the focus of Thyferran society and it is a very competitive culture. Beginning in the family business at a young age, many of Thyferrans never leave the planet; instead spend their life maneuvering their way up the corporate ladder.

Because of Thyferra's low gravity, Thyferrans tend to be rather tall and skinny. The climate is warm and humid, so fashions are usually abbreviated.
