The back story:
Jastra (the PC) has left his home a couple of years ago because he found in his father's desk a datapad marked with the Imperial Logo (he didn't check what it was). He was angry that his dad was working for the Empire (his perception, though). He left and travelled away, ending at Coruscant. He was then welcomed by Bounty Hunters, and managed to evade them...
Turns out, those Bounty Hunters were working for the Empire (he learned a couple of session later).
Jastra's father was arrested by the Empire for Treason. Turns out he wasn't really working for the Empire, he's a Rebel agent... His treason? Giving plans about a secret weapon somewhere in the the Despayre system
Imik is a Rebel contact that's trying to get him out of a certain Lieutenant who picked him up from the Kessel Mine prison.
During the last few games, they've ran the Shadows of a Black Son, the Trouble Brewing, the adventure of the GM Screen, Gun Nut (with some updates), and now they are starting the Hunter and Hunted.
I know my players are not regulars here, so after that one, I'm planing on having the Lieutenant (if it survives) get in trouble for having taken a prisonner out of Kessel and loosing him have to become a deserter and wanting his revenge on the PCs. If he doesn't survive, the Imperial Securty Bureau will be investigating the incident and track the PCs.
I currently have 2 players:
One is playing Jastra, the Botan Politico/Doctor with a Bounty obligation and a motivation is to protect his family from his Evil dad (looks like this will change!)
The other plays a Gand Outlaw Tech, who got caught upgrading spaceships and equipment for the Rebels (though he doesn't want to really get involved). Yet his motivation is to overthrow the Empire, or at least help the Rebels, without being involved too much.
I've added a NPC to the mix, an R3 Droid that was rebuilt by the Gand, and renamed R3-D0 (Redo). It's a Slicer, who also has a better shot with a blaster than any of the others. He has been equipped with a Blaster (permanently set to Stun).
