Maybe I'm just sleep deprived, but I don't understand how the Rebellion can liberate ANY worlds while the Empire is still in power (I.E. Before the battle of Endor). When were the Mon Calamari liberated and how could they stay that way long enough to use their orbital shipyards to construct vessels for the Rebellion?
Also, does anyone know of any good, condensed timelines that list events between 0-4 ABY that can be used as a good backdrop for adventures?
