A set of various rumors originating at makingstarwars.net offer details on what J.J. Abrams' "Star Wars: Episode VII" could be about. Of course, most of these rumors are based on "inside information" from "anonymous sources," so take it with a grain. Some parts of all this are just speculation, a kind of informed connecting of the dots. Most of it sounds plausible, but at the end of the day none of it may turn out to be correct. Or maybe it all will. Or maybe J.J. Abrams has an entire intelligence department on the set, feeding false rumors to various bloggers. (What? It's not like he wouldn't.)
Potential major spoilers ahead.
The first report from makingstarwars.net is about the film's villains. This one suggests that stars Adam Driver, Lupita Nyong'o and David Oyelowo are "Jedi hunters." These are reportedly servants of the Dark Side who, like the Inquisitor on "Star Wars Rebels," travel the galaxy wiping out any Jedi they encounter. (The report speculates that this group may even call themselves "Inquisitors," which implies that "Star Wars Rebels" ties in very closely with the new film trilogy.) These villains could be remnants of Darth Vader's quest to wipe out all surviving Jedi following the Clone Wars. Even though the Emperor is gone, the Sith still has devotees who are trying to resurrect the old order. These Jedi hunters are described as wearing "black and chrome" armor, not entirely unlike Stormtrooper armor, and wielding lightsabers.
No new government has arisen to take the place of the Empire, and various pockets of Imperial forces are still scattered throughout the galaxy. This same report believes that Luke Skywalker has spent the thirty years since "Return of the Jedi" fighting these Jedi hunters, and now he's gone missing just when his old friends need him most.
This jibes with Aintitcool's summation of the film's basic plot: "Han Solo is pretty much the main character of 'Episode VII,' leading a galaxy-wide search party for Luke Skywalker." Harrison Ford's broken leg is no doubt complicating matters, but no one is yet saying how the production plans to handle it. (Couldn't they just write his injury into Han's story?)
The next report refers to a storyline adjacent to the "search for Skywalker." This one suggests that John Boyega's character may start out the film as a villain, but when his spaceship is shot down and he crashes on Tatooine, he's rescued by Daisy Ridley's good samaritan. Boyega's story arc in "Episode VII" finds him seeing the error of his ways -- thanks to Ridley's character, who he shares a mutual attraction with -- and defects from the Jedi hunters to eventually become a Jedi hero.
Makingstarwars.net also believes that "Episode VIII" will find the Jedi hunters, or Inquisitors, or whoever-they-are, succeeding in their quest to resurrect the Sith, and then "Episode IX" is the climactic battle between Jedi and Sith, for the fate of the galaxy.
