"POWAAAH!!! UUUNNNLIIIMMITEEED POWAAAAAAAAAHHHHHHH!!!" ~ Sith culture and philosophy in a nutshell.
Seriously, everything else is just lip-service to make they're unending thirst for MOAR POWAH sound acceptable to other people, barring a few once-in-a-blue-moon oddballs.
By that standard, Ciaran is a fine Sith. She's pretty dedicated to the cause of increasing her own power. As far as I can see, her main argument with Sidious (besides him being in the way of Ciaran ruling the galaxy from behind whatever puppet throne or senate she sets up) is much of his scenery-chewing evil acts kill people who should be worshipping Ciaran as their saviour or destroys planets that she could Naboo.
I think she's just a Sith Lord in title only, unless I've simply forgotten which is very much possible. I don't really remember her being an avid user of the Dark Side.
She's been shown using the Dark Side, but doesn't seem to heavily use it (because doing so hasn't been necessary and because doing so would make her a slave of fate, not truly powerful in her own right).
And to be honest, Ciaran does the best job of living up to the Sith code of any character I've seen in Star Wars or Star Wars fanfiction.
Peace is a lie. There is only Passion.
Through Passion I gain Strength.
Through Strength I gain Power.
Through Power I gain Victory.
Through Victory my chains are Broken.
The Force shall free me.
Though of course, there is the oddity that Ciaran's passions are money, helping people, and especially helping people she's just robbed blind. But her attitudes are otherwise pretty Sithy to me.
And so far this whole quest could be viewed as an allegory for the Sith code. Ciaran started out as a jumped up gang leader/bartender, and gained power through her passion for information, credits and her rejection of the peace of the galaxy at that time - one of the first things we were doing is helping the Separatists and many of the early opportunities she grew fat on were the scraps she gained by aiding Plagueis and Palpy's plans. And she snowballed those gains into real victories that started to threaten Plagueis' plans, causing him to lash out at her which was what directly led to her developing her shatterpoint power and eventually led to the spirit of Plagueis being erased.
Remember that Palpatine's signature power is that he's a seer - perhaps the best there has ever been since the Sith were founded. But Ciaran's shatterpoint allows her to mess with that in a major way. The fruits of her victories means she's munching through the chains Palpy has forged at an ever increasing rate, even as she's been casting off the chains she's put on herself.
As we speak she's well on the way to owning the galaxy and achieving Sith nirvana.
Then, there's the way Vectivus especially, but also Asajj treats Ciaran. Vectivus definitely is still Sith. Asajj is, if I remember, also still identifying herself as Sith. Both of them treat Ciaran as a respected peer. Someone who is a genuine ally, someone who their Sithy goals are furthered by teaching and occasionally someone to learn from to become better Sith.
Ciaran is probably some sort of heretic. But I am pretty sure she counts solidly in the "Sith" column.
But I grant you that there is plenty of room for interpretation here. And either way, I suspect that Ciaran doesn't care much for anyone's interpretations of what sect she is. Ciaran probably just thinks she's Ciaran...
I hate to be that person, I really hate myself for what I'm about to say, but I did commit to some level of reasonable rationality.
At this moment in time Ackbar is the head of the Mon Calamari Guard, essentially the personal troops of the King. He has no training or experience in naval warfare. I'm unsure how he learnt it in Disney Cannon, but in Legends he got unintentionally taught by Tarkin when he was the Moff's slave. Tarkin liked to brag about how he was going to enslave more worlds and didn't notice the fact that his 'valet' was adsorbing what information he could.
So we can't use Ackbar, though if you want a Mon Calamari Captain we could have Raddus.
Hm, that whole bit about Ackbar being Tarkin's slave isn't in his canon Wookipedia page, it's on his non-canon Wookipedia page, so I guess Disney threw that out.
Still, you're right about him not being a naval officer about this point. In the new continuity, he seems to have mysteriously gained naval experience without any explanation between the Imperial attack on Mon Cal and the Battle of Yavin.
Of course, maybe Thrawn's re-organizations of the CNS defence forces have meant that Ackbar has been shuffled into the naval forces anyway... But even in such a case, he's probably a rather green commander, so ya, unlikely he'd be tapped to captain the interdictor.
Oh well.
Huh, I wonder if Force Users are in anyway aware of prayers and worship made to them?
Did Palpy ever try to set up an imperial cult? 'Cuz if this didn't actually hurt him, I bet he'd have done it.
