The Malkite Poisoners were adept assassins who trained in and perfected their poisoning arts on the planet Malkii, where they got the ingredients for many of their deadly poisons. They were a highly secret group, and were responsible for helping Contispex I of the Pius Dea cult in his rise to power as Supreme Chancellor of the Galactic Republic. Zlarb, a slaver who was killed by Han Solo, was known to be a Malkite Poisoner. Malkite poisoners, possibly including Zlarb, were known to have been involved in the death of the Mor Agmor Glayyd.
