Jadus Kess was created with the rest of his species by Darth Sirena, Zar Quwil, and Seren Teancum Mordavo. He was a Pureblooded Sith, or as close as could be, cloned using genetic material from an ancient derelict. Jadus was a member of the second generation of experiments aimed at aimed at resurrecting the Sith Species. He shared slight genetic resemblance to the Sith-Hybrid Exan Kess and so was named likewise. The spirit infusion was perfected reducing the amount of utterly useless subjects produced by the earlier cloning process. Jadus represents the first true success in the program, having both potential and the properly devious mindset.
