Battle above Harloen

In 4 ABY, an Imperial Navy task force led by Commodore Mogge intercepted the Blaster Brethren pirate fleet, commanded by the Mandalorian warrior Naastau, above the planet of Harloen where the pirates intended to sell loot from a recent raid. The pirates were defeated with only a single vessel remaining and its captain, Naastau, as the last remaining Blaster Brother who wasn't killed or captured. After managing to escape the firing range of Mogge's superbeam cannon, Naastau's ship fled to the Concord Dawn system. Prior to the operation, Mogge had spent several months working with elements of the Imperial Security Bureau to bring the Blaster Brethren down.
