The Arcanum functioned as a space station, ordered into construction by the Sith Emperor. Its designated function was the secure containment of perilous Sith artifacts owned by the reconstituted Sith Empire.
During the Galactic War in 3638 BBY, which saw conflict between the Empire and the Republic, the Sith Lord Tagriss, acting as a rogue element, raided the station. He pilfered both the Darkstaff and the Seeds of Rage for the Dread Masters. Darth Acina was appointed by the Emperor to protect the facility.
