Mission to Norval II (Imperial Period)

In 13 BBY, the Mandalorian warrior Naastau traveled to Norval II, which was the site of a disastrous battle between Fenn Shysa's Mandalorian mercenaries and Republic clone troopers in the closing months of the Clone Wars. He traveled to the site in search of a prototype disruptor bomb, which Shysa's mercenaries intended to use against their foes but were wiped out before it could be used.

Overview
Upon arriving in the system, Naastau was ambushed by a small group of armed scavengers, but managed to evade his attackers and continued his mission.

While he and another Mandalorian peer were investigating the battlefield, he encountered a Mandalorian who survived the battle and had been living in the abandoned battlefield for nearly a decade surviving off of what could be salvaged in the area. The survivor, who knew the area, notified Naastau that the bomb had been taken by Imperial Army troopers that searched the battlefield only weeks prior, and took it to a nearby outpost. The trio left in a land speeder in the direction of the outpost; during their transit, they were ambushed by an Imperial Army patrol whose scouts had noticed the three Mandalorians and hid until they passed by. An AT-ST walker was also involved in the ambushed, but was destroyed after Naastau disabled it with an EMP blast from his blaster pistol and subsequently destroyed it with explosive darts. They managed to fend off the ambush and make their way to the outpost, which was lightly defended. After a skirmish lasting minutes (and resulting in the death of the survivor, who sacrificed himself covering the other two as they made their way into the outpost's armory), Naastau managed to contact his astromech droid to swing his ship around and bombard the outpost, covering their escape. As Naastau fled the system, he was pursued by TIE fighters after a fleet of Imperial patrol crafts descended upon the system to investigate the outpost's distress beacon; he managed to eliminate a few starfighters before jumping out of the system. The disruptor bomb was brought back to the Mandalore sector where insurgents used it to destroy an Imperial Star Destroyer from within.
