The campaign I began in January wrapped up its first major story arc with the party of heroes deciding they want nothing more to do with the war between Jedi and Sith. Those that have fallen to the dark side killed their masters and those that stuck to the Jedi ways have now decided to abandon the order, finding common ground with each other in that they are done with it all. This comes right at a moment when they had achieved the majority of the goal the Council set out for them, interestingly enough. They have the means to accessing a power the Sith have been trying to discover, have chosen not to pursue it, and are planning to keep the key to said power. The Jedi tasked them to destroy the source of the power so the Sith couldn't obtain it.
Now we seem to be moving into a more Edge of the Empire style game. The party wants to acquire their own ship, send the Explore Core crew that was taking them on Jedi missions back home and start earning some credits. It seems they just want to survive and don't have any particular long-term goals in mind beyond that.
I'm pretty excited to be covering a different aspect of Star Wars for a while, though admittedly a bit disappointed the original plotline wasn't resolved (yet). I hadn't considered the group deciding to do absolutely nothing with the key to unlocking untold power and abandoning their quest.
