A conversion for 'Empire at War: Forces of Corruption', Return of the Clones is based on a what-if senario - what if parts of the old Republic had survived Order 66, leading to a civil war between the Empire and Republic. Meanwhile a grassroots Rebellion has started against the tyranny of the Empire, whilst Tyber Zann and his Consortium salvage old Confederacy droid, vehicles, and starships in order to make his own grab for power.
I just love it! It works well with this one story that me and a friend made where, though it not Clones, the faction has an Old Republic flare to its military.
