Around the time of 8 ABY, Moff Kentor Sarne, an Imperial warlord, launched a string of attacks on the Minos Cluster originating from his bases of power in the adjacent Kathol sector. Even though his forces were fewer in number, Sarne was successful, seizing and maintaining control of areas within the cluster. The New Republic had heard whispers that the Moff had acquired a novel type of weaponry, leading to the belief that this was the reason for his military's battlefield advantage. Eventually, the New Republic was able to force Sarne's military back into the Kathol sector.
