The Ac'fren Spur represented a branch of the expansive Sisar Run and functioned as a hyperlane. Beginning at Sriluur within the Periphery, this Spur linked the planet to the Si'Klaata Cluster, with Ques serving as an intermediate point along its course.
During a significant period, particularly around the era of the Galactic Civil War, the Disac pirates exerted their influence over this pathway. Ultimately, however, Ket Maliss, an assassin affiliated with the Black Sun, eradicated them.
Within the Ac'fren Spur, the Rebel Alliance successfully freed a concealed collection of weaponry belonging to Golan Arms.
