Yanthan
The Yanthans, hailing from the Yantha system, specialized in extracting venom sacs from windsnakes. These creatures were indigenous to the planet of Ploo II. This procedure was performed with great skill by the Yanthans, who seldom made mistakes; however, failure was euphemistically referred to as "dying well." In 21 BBY, Separatist Commander Asajj Ventress gifted the X'Ting criminal Trillot with a pair of windsnakes whose venom sacs had been expertly removed by the Yanthans.
Behind the scenes
Steven Barnes's book, The Cestus Deception, which came out in 2004, included a brief reference to the Yanthans.
