Honestly, a pretty big part of my motivation for Voices of the Force is to do something new.
I'm tired of Star Wars stagnating. Sometimes I'm in the room when my parents are watching Acolyte or the Ahsoka show or what have you, and every time I hear that they introduced a new O66 survivor trying to keep all the Jedi ways alive or something like that, I just... tune it out. Not that Legends did any better on that particular score, of course, but that's exactly my point.
That's part of why Fate of the Jedi, for all its numerous faults, is so enjoyable to me. It attempted, and had some success in, shifting the paradigm in largely new ways, like showing a subculture of Sith that could understand when not to stab each other in the back, and ultimately the Jedi becoming politically independent. The cosmic horror angle of Abeloth's portrayal, especially, was an area that the EU hadn't done very much as far as I know, and Denning's actually good at it.
And as I've come to know that, after reading on Wookieepedia about the connection of Abeloth's origin story, it's increasingly fascinating to do stuff set after FotJ because of how many new things it gives me an opportunity to do. Technically, the concept of using forward time travel to explain Ahsoka's absence in the EU post-TCW has been in my head since I read Crosscurrent at something like 8 years old, when that book was all I actually knew about the EU.
Now, the most interesting part of this AU to me is 16-year-old Ahsoka's relationships with ass-end-of-Legends characters that maybe 0.01% of Ahsoka's fanbase has even heard of.
TLDR, I guess: I think I'm at my best when I can do things in my writing that only I'm crazy enough for.
