The SLV-16 serum was a potent psychoactive medication developed by the Intelligence arm of the reconstituted Sith Empire. It sapped the willpower of most humanoid species, leaving an individual obedient and helpless for one hour before its effects wore off. Blue in coloration, one such serum was given to the future Cipher Nine agent by Imperial Command for use on a slave leader on the Sith capital planet Dromund Kaas.
