The Ac'fren Spur was a hyperlane and a branch of the larger Sisar Run. The Spur originated at Sriluur in the Periphery, and connected the planet with the Si'Klaata Cluster passing through Ques on the way. For many years, around the time of the Galactic Civil War, a group known as the Disac pirates were a presence on this route. However, they were later wiped out by one Ket Maliss, a Black Sun assassin. The Rebel Alliance liberated a Golan Arms weapons cache in the Ac'fren Spur.
