A while back my Star Wars group (in a now ended campaign) awakened a 4000 year old Sith Priest on Yavin 4 and inadvertently led him to the Temple of Exar Kun where he made contact with the spirit of his Master/God and the small Cult in the Temple. They left before it hit the fan, but they know a Inquisitor group sent to investigate the spike in the Force at the contact was mind controlled by the Priest. They were never bothered about follow up and went on to acquire a shipping route contract and a decent (mostly) legit income. Just as the campaign was ending however, after being unable to raise a contact on Yavin and hearing stories of odd disappearances they decided they should do something about the mess they made, but player/gm fatigue was quite large by then and we stopped.
My players however have expressed in picking this back up, but rather than use their 1500 point high end characters I have been musing doing low level characters who are working for their high level one's Company doing missions which have an aim to impact the final fight vs the Priest and Cult. I was thinking of doing this on a timer- the Cult is attempting to resurrect Exar Kun at X point and they have until then to work against them. I was thinking missions like:
-Recruit more forces for the fight: the players like more diplomatic missions so gaining recruits might be there sort of thing.
-Gain more ships: just before the end the High-Levels got word of a Venator that might be salvageable, so sending the new crew to get it is an idea
-Stop the Cult gaining X or Y McGuffin
-Scouting on Yavin IV
-Preparing for the Big Fight
Trouble I am having is how to time this - do I set a fixed number of missions? Do I pick a date on the calendar and just keep notes of the days until the resurrection ritual but drop hints its coming to chivvy them along?
Also what if they fail a mission or succeed exceptionally well? Do should I record impact for or against the Company and Cult?
Any GM advise welcome!
NOTE: Vader and the Empire are unable to just sweep in and glass Yavin as apart from the first 'burst' the Force has gone quiet, and the Controlled Inquisitors reported everything was fine, and there is a Major Insurrection broken out on Corellia, and they are gearing up for Hoth...
