To promote the Star Wars High Republic book series, they’ve released an animated short, the first of many. The series sets the stage and introduces Vernestra Rwoh, a gifted young Jedi Knight in the High Republic.
The High Republic series is set 200 years before the events of the Skywalker saga and 800 years after the fall of the “Old Republic”. I have a feeling it’s going to lead to more books, a video game and eventually a movie or tv series. You can buy the books here
