X-1
this was the codename given by Myk Bidlor to the poison used to kill Aruk the Hutt. Bidlor discovered that it was produced by the Malkite Poisoners, and was created from the stamen of a plant which grew on a planet known only to the Malkites. This made the drug prohibitively expensive, which led Durga to believe that clan Desilijic was behind its use. Large doses of X-1 were immediately fatal, but small doses create a dependence which can be deadly if the substance is withdrawn.
