Star Wars Jedi: Fallen Order features Darth Vader, lightsabers and other Star Wars trappings, but is it official Star Wars canon?
The term “canon” is defined as ‘a collection or list of sacred books accepted as genuine’ and while that might be pushing it when it comes to Star Wars, the principle is the same. Is Star Wars Jedi: Fallen Order official Star Wars canon? Do the events in the game count as having happened in the Star Wars universe?
The short answer is yes. When Star Wars: The Force Awakens was released, Lucasfilm/Disney declared that all prior Star Wars games/books/films didn’t count, giving them ‘Legends’ status, making them a sort of Star Wars ‘what if’. Since Star Wars Jedi: Fallen Order comes after that, Fallen Order counts as official Star Wars canon.
The long answer is that, for a long time, Star Wars movies were considered ‘main’ canon and books/games/shows, while still canon, carried less weight. It’s not as clear whether this still stands – but if something in Star Wars Jedi: Fallen Order or any Star Wars game contradicts what happens in the movies, the movies are considered correct.
So if there’s a Star Wars Jedi: Fallen Order sequel where the Death Star blows up because Cal Kestis accidentally downloads his Linkin Park MP3s to it, that wouldn’t be considered canon.
