100% true from the new SW Archive Book GL interview.
Maul and his female apprentice Talon.
I’m sure some will now claim this is brilliant Maul > Emperor
Ah, so that explains the Talon connection.
Quite a bit of George's ideas ended up in the Disney flicks then.
The two sibling heroes of George's ST, Sam and Keira, morphed into young Han (as you can see from Sam's look below), with Keira's name going to Han's love interest (spelling changed to Q'ira) and her Force powers and general look went to Rey. Sam's seduction translated to Ben Solo's seduction, with them being a dyad instead of siblings.
So George wanted to bring back Maul (again, lol) and JJ wanted to bring back Palpatine. Yeah if I was Iger I would have granted JJ's wish over George as well. We owe everything to Lucas but the guy absolutely requires others with the power to tell him "no" once in a while.
Even then they still let Maul sneak in regardless which I'm fine with. But the big bad of an entire trilogy? No, no, no.
