That one is indeed canon!  I think Iden is an entirely canon character?  I think I read the beginning of it (then got distracted, as I often do) and was feeling like there’s just no way to really win with Iden’s character.  Either you have to make her a horrible person to be so loyal to the Empire OR you have to make her really dumb to not notice what’s going on.  Or else you just sort of have to ignore all that and avoid the question altogether.  And it feels like it winds up being that last one that really is what happens with her.
I love Iden as a character, I love her story as a personal one.  And I’m wondering–as I’m reading all these various Imperial POVs, like Rae Sloane and Ciena Ree and Zare Leonis and Wilhuff Tarkin and Darth Vader, etc.–if maybe there is a point being made, on a bigger scale, about how people just sort of Don’t Think About the bad stuff.  God knows that would be a really fitting thing to play with, given the current political climate.  (My problem is then that nothing is done with it, it hasn’t yet come to any satisfying narrative head for me yet.  But I’m still reading and I’m a slow reader when I’m ALSO reading fic and writing meta about everything I read!  XD)
yeah I mean I guess I'd reframe the question not so much as
“How could she be an intelligent and decent person, if she was so deep into the Empire before this?” But in general "Why are you serving the Empire given what it does?" I don't need it to come down on morality (though there will always be that question given what the Empire does), but the answers themselves can be interesting. So like Thrawn's reason is different from Arihnda's reason is different from Ciena's, and so on. I find that really interesting to explore in general
I had to put this on a separate post because this is EXACTLY what I’ve been feeling, yessssss. I’m with you that I don’t need the story to come down on the side of morality (I’m a Darth Vader fan, after all!) or even necessarily answer the question, because I think it’d be fascinating to explore something that a lot of people face in a fascist (or growing-into-fascism) government: What does it say about the nature of the beast that otherwise “good” people ignore these things?
There’s a lot to explore in how otherwise good people join the Empire because they don’t have any other reasonably viable options if they want to live or not put their families in danger. There’s a lot to explore in how some people are scared and they join because they feel they have to. There’s a lot to explore in that the Empire wasn’t always voluntary!
But I need the question--whether answered or deliberately ignored--to be part of the story. And I feel like, for all that I got bored reading about the space football parts, stories like Servants of the Empire (and, as you say, Rebel Rising?) are aware of that question, about how Zare feels this intense disconnect between what he knows his happening versus his family who are unaware, but he has to struggle with how much they would believe him, how much it would destroy their family if he told them, etc.. So he keeps quiet, but the question is very much there.
I feel like the Darth Vader and Dark Lord of the Sith comics are aware of it as well, like the Tarkin novel, in that the answer is, “They just don’t care because they’re not negatively impacted by it/they’re using that negative impact for their own justifications.” I could believe this of Iden Versio--she doesn’t see the truly ugly things, she’s been taught that the people getting hurt are deserving of it, she’s been taught that if you’re loyal, if you keep yourself toed to the line, things will work out, and anyone who doesn’t is just being selfish or troublemaking.
Who I REALLY want an answer for this is Rae Sloane. She believes so strongly in the Empire, she believes the Rebellion is bringing lawlessness and chaos into a galaxy that desperately needs structure because otherwise people just turn around and destroy each other. And she hates working with the propaganda and people like Pandion or Gallius Rax, but how does she justify the cruel things the Empire does, like the enslavement of entire worlds, with making the galaxy a better place?
With Ciena--at least so far as I am--she hasn’t seen the ugly sides of the Empire, as well as she is incredibly grateful to the opportunities that it gave her, the resources she has now, the chance to actually be on even ground with people who would have lorded it over her back on Jelucan. I get why she is fiercely loyal to such an awful regime!
But Sloane worked with Tarkin. She worked with the worst of the Empire. She can’t be unaware of the truth, she understands that they spin stories to benefit themselves. She can’t be unaware of why they enslaved the Wookies or the Twi’leks. How does she square that with thinking that Rebels are only bringing chaos to the galaxy and that she thinks the heart of the Empire is good?
Is the point ultimately that she’s sticking her head in the sand, too? That she believes so strongly in the Empire that she doesn’t see the true ugliness right in front of her? Does she just straight up not care about the Wookiees and Twi’leks? Does she buy into the idea that they deserve what they got for going against what the Empire wanted of them? Does she think that the sacrifice is worth it, for the “greater good”?
I feel like there’s a really good story in there, how she can be an honorable person while still seeing so much ugliness in the galaxy and, man, do I want THAT story! :D
