Around 3638 BBY, Tagriss, the Sith Lord, orchestrated a raid targeting the Arcanum. This Arcanum was a location managed by the Sith Empire for the secure storage of perilous Sith artifacts, and Tagriss's goal was to pilfer certain relics for the Dread Masters. To protect the Arcanum, the Empire deployed a Sith strike team, while the Galactic Republic also sent their own strike team to thwart Tagriss's objectives. However, despite these defensive actions, Tagriss managed to abscond with both the Darkstaff and the Seeds of Rage.
