I've got an idea for a campaign, or at least extended series of adventures for Age of Rebellion. I imagine that the PCs learn over a series of adventures that the Empire is building a new class of dreadnoughts. Further they learn that the lead ship of the class, the Bellator , is already earmarked for Darth Vader's personal naval force, Death Sqaudron. As they learn more about the ship it is clear that the Bellator poses a clear danger to the Rebel forces. The Bellator's combination of great speed and firepower could pose a great danger to any naval force or evacuation transports that it encounters. So, the PCs are made part of an operation to... Sink the Bellator!
Mostly I'm not sure how to structure the adventures leading up to the climax. I want the PCs to steadly learn more about the Bellator and the threat it poses to the Rebel Alliance.
