I'm happy to see that they've announced a sourcebook for the dawn of the rebellion period, as I am currently co-GMing a campaing set just before the battle of Yavin. We're mostly doing Edge of the Empire stuff, but I'm working on having them join the rebellion in some way. And I was wondering how the official adventure supplements works for the pre-Yavin period. I've looked at some of it, and it seems most of it reference the destruction of the Death Star and the adventures are intended to play after this. Friends like this looks like it could work Pre-Yavin, am I right about that? What adventures would you recommend / suggest for that period?

The new source material seems to base it around the rebels TV series, rogue one and maybe the Han solo film. The defence of arda is a good one to introduce your edge characters to the rebellion
