For their own particular reasons, Cpt. Grayviper, the Tam sisters and a wookie bounty hunter had come into the employ of Zorbo the Hutt as a way to pay off their various debts to him.
The group was assigned to retrieve some Imperial-issue surveillance gear. The surveillance gear was held on an Imperial space station and the group managed to retrieve it by impersonating Imperial officers on a supply run.
The newly acquired surveillance gear was delivered to another planet to trade it for smuggled weaponry. As it happened, the trading party was overtaken by an arm of the Rebellion. They attempted to take the equipment by force and keep the guns. A pitched battle ensued, with the Imperials arriving at the last minute, intent on arresting everyone involved. The group managed to kill the surviving merchant and then Captain Greyviper spun a tale of rebel deceit, that those were his guns and he had brought them to trade, but when he discovered the surveillance goods were stolen property, he opened fire like a good Imperial citizen. With the storm troopers mollified, Grevyiper and his crew took “their” shipment back and left the troopers to clean up a mountain of rebel bodies.
With a pile of weapons in hand, the group returned to Tatooine and was swiftly tasked with drumming up business on the planet for them. To do so, the group stoked the ire of the local sand people and drummed up fear in the local populace. All of this was done, surprisingly, without following through with Greyviper’s plan of kidnapping a few children, then saying the sand people did it.
