I have a few ideas for the New Jedi Order series, and have done some changes.
1.) The main antagonist is Antinnis Tremayne from the EU (
Antinnis_Tremayne) with some changes. He betrayed the group of Jedi he was hiding with for power, and is involved with the secret church of the Dark Side (which is so top secret even most imperials were unaware it existed). Tremayne is kinda hoping to become the new Emperor, and is manipulating an ambitious but kinda stupid politician into being his puppet (it's a reverse of the Palpatine Vader Dynamic whereas the Palpatine figure is really a buffoon and the Vader analogue is the one actually running the show.....which is also similar to how Palpatine was originally envisioned funnily enough.) Tremayne will be seen as a major milestone in pop culture villainy since he's a.) actually extremely competent and b.) is capable of putting on a likable facade to hide what a monster he truly is. He actually manages to successfully corrupt one of Luke's students to the dark side (Though in true Star Wars fashion Luke is able to save them)
2.) I think that aside from the big three Luke's first class should also get a lot of focus. Luke is trying to settle into the mentor role (though of course he does struggle with it). Since I want to be REALLY ballsy I think that the main protagonist of this group is a female character, who is actually fully fleshed out and developed with a good arc (so a MAJOR milestone for girl characters in animation).
I definitely think they should have a hard scrabble life or some degree of tragedy, and I'm debating two possible backstories
a.) They're a former slave or street rat
b.) They were raised by Tusken Raiders after their family was killed (I'm thinking that the Tuskens found her while she was lost in the desert and in a show of mercy took her in); her adopted tribe was brutally wiped out (either by Imperials or a criminal gang). They initially have somewhat of a difficult time adapting to "civilized" norms, but grow into a badass Jedi over the course of the series.
3.) Concepts like "Sith", as well as other worlds that will be prominent going forwards (Dathomir, the Tapani Sector) will get introduced here. Byss is also the site of the series finale; after Coruscant is liberated the heroes pursue Tremayne to the core to stop him once and for all.
