Overseer Harkun is a male human sent to meet Inquisitor player characters upon their arrival on Korriban. Harkun has been charged with testing new initiates in order to identify an Apprentice for Lord Zash; Overseer Harkun views slaves as filth, and believes it is impossible for a former slave to rise to power among the Sith.

An overseer active during the Cold War, Harkun had been tasked by Lord Zash to test a group of acolytes so that she may select the superior of the group as an apprentice. Among those acolytes was the Sith Inquisitor, who because of their former time as a slave he treats with contempt. After his arrival he tasked the future Inquisitor to see Spindrall, who would give the acolyte a trial of blood. After completing the task, the acolyte returned to Harkun, who killed Kory and then presented Ffon Althe to the others. He sent the slave to see Zyn and interogate Alif, a trial accomplished once again perfectly. Harkun was skeptical, believing Zyn had somehow assisted the former slave. He then sends the acolyte to retrieve a holocron from the tomb of Marka Ragnos, and after their return insists the holocron. He then tells Althe to kill Gerr, an apparent failure. Later, the slave is tasked to bring texts from the tomb of Tulak Hord, which later impresses Lord Zash. The slave is later sent to the second floor of the Academy, truly an assassination attempt. Unfortunately for Harkun, the pair of acolytes fail to eliminate the former slave. He gives an advantage to Ffon and allows him to depart earlier for the tomb of Naga Sadow, but with Zash's help, the Inquisitor succeeds in possessing the map with further assistance from the long-imprisoned Dashade assassin, Khem Val. In a final attempt to secure Ffon's victory, Harkun demands the map from the future Inquisitor and instructs Ffon to lie and claim the position of apprentice to Lord Zash. However, intimidation from Zash ultimately forces Althe to admit the truth and secures his death at the hands of the female Sith Lord. Albeit exceeded in authority by Zash, Harkun threatens to harass the newly accepted apprentice throughout their career as a Sith.
Some time later, after the Sith Inquisitor has become a Lord of the Sith, and orders Harkun to administer the trials to a group of slaves, one of which, the Kaleesh Xalek, shall become an apprentice.
