The Yanthans were beings from the Yantha system who excised venom-sacs from windsnakes, creatures native to the planet of Ploo II. The Yanthans were experts at this task and rarely erred, although doing so resulted in what they termed dying well. In 21 BBY, Separatist Commander Asajj Ventress presented the X'Ting criminal Trillot with two windsnakes that had had their venom-sacs removed by Yanthans.
