Star Wars Legends, formerly known as the Expanded Universe (abbreviated EU), encompasses every one of the officially licensed, fictional background stories of the Star Wars universe, outside of the original six Star Wars films produced by George Lucas and certain other material such as Star Wars: The Clone Wars, created before April 25, 2014. It is derived from and includes most official Star Wars–related books, comic books, video games, spin-off films, television series, toys, and other media created before the date. This material expands and continues the stories told in the films, taking place anywhere from over 36,000 years before The Phantom Menace to 136 years after Return of the Jedi. The issue of which aspects are canon was one of the most hotly debated topics among fans.
On April 25, 2014, Lucasfilm Ltd. announced that in preparation for the upcoming sequel trilogy, the Expanded Universe would be retconned; past tales of the Expanded Universe will be printed under the Star Wars Legends banner, and a new continuity has been established that consists only of the original six films, the Star Wars: The Clone Wars television series and film, and all future material from that point onward. Though past elements of the Expanded Universe have been declared non-canon as a whole, they remain a resource for future Star Wars material to reference, thus bringing these elements into the new continuity as canon.[1][2] Until today, the only Legends product that is still being released is the video game Star Wars: The Old Republic, along with short stories published at the Star Warsblog.
Can stuff be made canon again? Sure.
But it’s frustrating cause it’s in this weird Schrödinger’s Cat phase neither living or died.
And old storylines like the aforementioned Knight Errant aren’t getting continued anytime soon if ever at all.
To say nothing of games like 1313 getting trashed and the license going too… well we all know what happened there.
