My PCs have just completed the open scenario and are no working their way through Long Arm of the Hutt, but I want to throw an interlude in with ten discovering ruins of an ancient cult. The times are perilous and the cult is returning to power. I want the leader to be a nemesis for the group.
But here's the thing. Most cults I have found in Star Wars are related to the Force. I don't want that or a droid base one. Any ideas?
