Rogue One: A Star Wars Story is almost here, and there’s a lot of pressure riding on the film, as the first Star Wars universe spinoff movie that could either launch or kill the fledging “Star War Story” brand. One of the things that makes the Star Wars universe special is the lived-in feel — characters drop casual references to fantastic events, with fans and writers taking it upon themselves to fill in those gaps, whether it be new theories or the now-defunct Legends canon. In fact, Rogue One is just one such story, telling the tale of how the Rebel Alliance came to acquire the Death Star plans from A New Hope in the first place.
