A savorium plant The savorium herb represents a specific plant species. It was engineered by Zorneth, an Ithorian botanist, in collaboration with Klorr Vilia, a Human botanist. Upon consumption, the herb induced a state of pure tranquility and delight, while simultaneously fostering a submissive attitude and diminished self-restraint. Individuals affected by the herb were commonly called "smilers" due to the constant smiles they displayed. The herb earned the nickname "slave drug" because of its appeal to slavers, pirates, and other criminal elements who exploited its mind-altering properties.
Following Klorr's experience with the herb, Zorneth aimed for widespread production to ensure universal happiness. Nevertheless, Vilia made the ultimate sacrifice by eradicating all existing savorium herbs.
Despite Vilia's actions, persistent rumors suggested the continued existence of savorium herb, with whispers of clandestine harvesting operations scattered throughout the galaxy.
