Set Harth was a male Human Dark Jedi active during the decades following the Ruusan Reformations of the Galactic Republic. Formerly a Padawan of the Jedi Order, his Master Aru-Wen was slain during the waning days of the Ruusan campaign in the New Sith Wars. After Aru-Wen's death during the final battle of the war on Ruusan, Harth was trained by Master Obba of the Council of First Knowledge. Obba's obsession in the research of Sith artifacts led to Harth's fascination with the Sith, and Harth fell to the dark side of the Force. Harth then abandoned the Order and moved to Nal Hutta, where he set up a mansion, as well as on other planets under his many disguises, to store all the dark side artifacts he could find.
