For those of us that have been fans of the Star Wars universe for decades, we used to have a pretty solid understanding of what happened after the movies. We know about Grand Admiral Thrawn, Mara Jade, the Emperor's clones, the New Jedi Order, and more. Unfortunately, when The Force Awakens was being made, all of those facts and stories were collectively dumped into the "Legends" category. As such, those stories can be thought of as some sort of alternate universe. And that means we have a lot of catching up to do with our old friends.
