Xenobi was a biotech company affiliated with the Sith Empire that was a rival of the Republic-allied ChemFlex. During the Cold War, the Empire persuaded Xenobi to attack and sabotage ChemFlex Labs, ChemFlex's facilities on Nar Shaddaa; however, the Xenobi thugs released biotoxins that ChemFlex was studying, and they were infected along with the lab animals. The infected were wiped out by Republic forces in order to prevent the spread of the viruses.
