The idea of a Force user who doesn’t label themselves a Jedi or Sith is nothing new in “Star Wars.” The galaxy far, far away has famously housed people known as Gray Jedi, who rose to prominence in the “Star Wars” Legends continuity. The term generally refers to those who walk the line between the light and dark sides of the Force and elect not to affiliate with the Jedi Order or the Sith. It’s also used to describe Jedi who may still practice the Order’s teachings while acting and speaking in ways not condoned by the Jedi Council.
With that definition in mind, the big question is, why is Baylan considered a Dark Jedi and not a Gray Jedi? He was once a Jedi who left the Order behind and sought out the dark side without becoming a Sith, so shouldn’t that label work for him? First and foremost, it’s worth remembering that Gray Jedi are purely a Legends concept, too. Additionally, the argument can be made that he has strayed closer to the dark than the light rather than seeking balance between the two. Thus, even if the Gray Jedi title was canon, it wouldn’t quite fit Baylan’s honorable yet sinister nature.
In the event Baylan Skoll returns to the “Star Wars” forefront in the future, it’ll be interesting to see how his stance on the Force changes. Will he remain a Dark Jedi, return to the light, or delve deeper into the dark? We’ll just have to wait and see.
