Since the time of that revelation, a number of fan-created theories have run rampant on the internet, most seemingly only creating more questions as to whether a set of post-Return of the Jedi/pre-The Force Awakens films will ultimately also need to be shot to focus on the Darth Vader mask as well as the origins of Kylo Ren.
The film doesn't spell it out, but Star Wars fans have constructed plenty of theories.
According to Screen Crush, in the "Art of Star Wars: The Force Awakens" book, concept artist Iain McCaig said Christensen was originally going to appear in "Star Wars: The Force Awakens".
One of the biggest surprises about The Force Awakens is how Kylo Ren, the Star Wars universe's new villain, was handled.
And yet Kylo Ren's keeping it locked away safely in his chambers on board the First Order's finest star destroyers and battle cruisers. (As Peter correctly predicted.) It hinges on Bazine Netal (Anna Brewster), the character who rats out Finn and Rey to the First Order at Maz Kanata's fortress. Most notably, if the Stormtrooper captain was on Endor, it's possible that he might have stumbled upon a Darth Vader's funeral pyre and made a decision to keep the burnt remains of the helmet as a souvenir. Mind you, those last two details are not confirmed. Ward was just trying to make a successful website about Star Wars, but knew that some unique information about The Force Awakens would go a long way toward achieving that success.
Within the short story, Bazine Netal, a gun for hire (whom you might recognize from the Cantina scene in The Force Awakens), is tasked with retrieving a mysterious package for an anonymous client.
