Bloodletter, a moniker given to a corporate spy, was employed by the Vratix Ashern group in 31 BBY to penetrate the Bacta Cartel. Following a near-fatal run-in with a Mandalorian clad in blue and silver armor, Bloodletter unearthed the secret of the hybrid kolcta. Not long after the conclusion of the Bacta War, Bloodletter published an autobiography concerning the Thriving Season, entitled Thrive or Die. Despite being a notorious individual, Bloodletter's true name and even their sex are still a mystery.
