Rieekan, a Human male who held the position of Bureau Chief, served within the Republic Strategic Information Service. During the era of the Cold War, he oversaw SIS operations conducted on Nar Shaddaa. When Imperial forces commandeered the Power Guard Project and abducted SIS Agent Galen, Rieekan sought assistance from a Jedi Knight to both recover the project and rescue Agent Galen. Tragically, Imperial forces launched a raid on the SIS headquarters, resulting in the deaths of Rieekan and several other SIS agents.
Before the Cold War between the Sith Empire and the Republic, Rieekan, a human male, became a member of the Republic Strategic Information Service (SIS). By 3643 BBY, Rieekan had risen to the rank of Bureau Chief for the SIS branch located on Nar Shaddaa. This unit maintained a concealed headquarters on the Promenade, accessible via a clandestine turbolift hidden behind Gudnem's Gadget Emporium.
In the year 3643 BBY, Lord Sadic, the apprentice of Darth Angral, took control of the Republic's Power Guard Project on a specific planet. SIS Agent Galen, who had arrived several days prior to secure the project, vanished after contacting Rieekan. Shortly after, a Jedi Knight arrived, seeking both the project and the missing Galen.
Despite the fact that only half of his agents responded to the omega alert sent out by his subordinate Special Agent Korol Tander, Rieekan remained determined to maintain their base located beneath the shop. He dispatched the Jedi Knight to the Nikto Sector in an effort to locate Galen, who had disappeared while searching for a contact kidnapped by Angral's forces. He tasked the Knight with recovering Galen's reports, which the agent had left at designated drop points within the area, while also cautioning that the Nikto gang known as the Kintan Kings controlled the Sector.
Once the Knight retrieved Galen's reports, Rieekan deciphered them and shared their contents with the Jedi. Galen's investigation had led him to the Power Guard recruitment center, where the Jedi discovered that Imperial forces had seized control of the facility. The Knight defeated the Imperial shocktroopers occupying the center and freed Vell Narroc and the other recruiters. Utilizing information provided by Narroc, the Jedi and Rieekan determined that the Power Guard lab was situated in the Red Light Sector. Rieekan then instructed the Knight to disable the sector's power grid to pinpoint the lab's precise location.
Following the trail, the Knight arrived at the main Power Guard Cybernetics Lab, where he witnessed Imperial Commander Graul communicating with Lord Sadic via holocomm. After defeating Graul and his Mark I Power Guards, the Knight hastened back to the SIS base, only to find that it was too late. Sadic's Mark II Power Guards had already launched an assault on the base, resulting in Rieekan's death.
