Savorium

This herb was discovered by Klorr Vilia about ten years before the Battle of Yavin. Vilia was looking to create an herb that would appeal to a wide variety of species and palettes. What he created was a large, tree-like plant with leaves which, when consumed, produce the illusion of rapture. Vilia became the first victim of the plant's effects when he used it to prove to Zorneth that he had created the wide-appeal herb he had set out to create. Vilia was suddenly locked in a blissful state, and Zorneth was struck with the realization that savorium, in the wrong hands, could be used as a devastating weapon.

The users of the drug, known as Smilers, are locked in a perpetual state of bliss, and often require protection. Zorneth created the Caretaker virus to covertly use droids to protect them.
