Looking for some free advice on the next arc of a year-long campaign. We've had some player & character changes recently, so only 3 of the 6 original characters are still with us. The group has both a smuggling and a bounty hunting element, with a good/moral-leaning to them. This next adventure should hopeful make the group a little tighter and pull both sides together.
The plan is to bring up part of the Darryn's past (group pilot/captain). The ship he was serving on pre-campaign had a mutiny; he and the other loyal members were stranded, and the captain (Darryn's mentor) was executed. Both Darryn and his mentor were part of the Black Bha'lir smuggling group, which is still a major supplier of jobs for the PCs. One of the new players made the Bha'lir part of his background as well, as a junior member who has come under Darryn's wing.
The PCs have earned a decent reputation, and now seems like the perfect time to bring up the above. The group's Bha'lir patron found some info on the leader of the mutiny, last seen on Nar Shaddaa (mostly because I just picked up the new Hutt sourcebook). The PCs task will be to track down the scum and execute the Rite of Retribution on him.
I have some vague ideas, but I don't want the mission to be just a "go to this place, find the guy, gun him down". Any advice on twists to the story? Suggestions on checks to be made, avenues to be pursued, trails to be followed, etc.?
Thanks in advance!
